Mechanic here. I can't even begin to list all the things wrong with this. That "grit" is the metal shavings caused by using kerosene. Pro tip: Change your oil at the proper interval and use a quality filter. You will be fine.
I've been a mechanic for almost 30 years and I cringe when I see people doing a flush like this. All that grit is going through your oil pickup and pump and all of your galleries. I've seen peoples oil pump pickup come out so clogged you cant even see the screen
I used to be a GM mechanic at a Chevrolet dealership and had a local mailman who owned a 1972 Impala with a 454 in it We did all of his oil changes and he always demanded 6 quarts of oil and 1 quart of ATF. At around 200,000 miles (with no engine repairs) I changed valve cover gaskets on it and was amazed. The engine was SPOTLESS inside! It looked like a brand new engine! Last I heard was that he got over 400k out of that car with no engine repairs before he sold it and bought a new car.
Just change your oil and filter on time or little earlier, and also use high quality oil and filter, use the right type of oil grade, type and amount, as well as proper oil filter, and it will run good for long time.
I don't know what the negatives will end up being from this, but even really sludgy engines are usually cleaned up by using premium synthetic oil with relevant additive packages. For example, Mobil 1 High Mileage just indicates to do a few shorter.oil change intervals so the oil can slowly and safely dissolve deposits into solution for removal during the drain.
The grit you have found is in the pan and does not enter the engine oil galleries. This is the sump reservoir that delivers oil to the filter. The filter prevents this debris from entering the engine. If you feel compelled to flush this debris, then pour the kerosene down the dipstick tube with the drain plug removed and capture the kerosene in a container. This will prevent the kerosene entering the engine, diluting the new engine oil, and causing a dry start after the oil change.
I use a quart of Marvel mystery oil a few days before I do my oil change. I never get sludge buildup and it cleans lifters and piston rings quite affectively. I’ve tried this technique for 40 years and as an engine builder
Marvel Mystery oil. The mystery is - what is it good for? That's a joke. It's great stuff. I've used it on aircraft engines for years. I also don't have sludge in my engines. Sea Foam is the same stuff.
@@robertthomas5906 I don't know if Sea Foam is the " SAME STUFF " but they both work slowly & are more gentle on the engine. I've personally had better luck ? with Marvel especially for sticky lifters.
I add a quart of MMO to my engine after a new oil change. I don't believe having an extra quart in the crankcase of a 6 quart engine hurts anything. I change at 3000 miles. Never had a problem.
In older engines this is actually true. The sludge acts as a seal for all the bearings. That's why you should never clean out your oil like that or even with oil circuit cleaner in an older engine. There are also CONs for this in newer engines with VVT and things like that. As long as you have no problem, don't try it. The cleaner might release grit and sludge, which can go into your VVT solenoids or similar things and block them.
That is true. I have heard that with transmission Flushes. Only change what's in the pan. Ya don't wanna empty out a transmission of all or alot of it's fluid because all the new fluid with all it's detergents will clean all them old ass seals up & all those old ass clutchs out and pretty soon it's leaking & a slipin'. If ya go puttin a solvent in yer oil then YEP it's gonna clean the hell outta some seals & bearings. Not to mention help all the sludge & gunk travel thru the rest of your engine. But wtf do I know. I'm just am old Hellbilly. Hahaa
As a journeyman HD mechanic I'm horrified. If you want to destroy your engine and starter this is the quickest way to do it. There are pickup screens before the oil pump and a filter in the circuit. Rotating your engine with kerosene as a lubricant will destroy your mains and valvetrain. This completely disregards oil wedge theory and points to sludge as the cause of most engine failures, not true. Don't do this, bad idea. Also, engine oil gets dark because it has detergents in it, most large diesels will have jet black oil after 30mins of running. Color of oil is less important than viscosity and acid content(or total base number). The creator of this video is not posting proven maintenance techniques.
I know this is slightly off topic,but I've used Fram oil filters for years until I saw a video with the guy who cut open 4 or 5 popular filters to show how much filter material is inside. Fram failed miserably,but Napa & Wix rated the highest. Needless to say, I paid a few bucks more for the wix,but it's worth it!
Your big end shells are made of a very soft material and have a grove cut in them ! The grove fills with oil so that your crankshaft etc are actually not touching any other metal surface ! ie there is a fine film of oil in-between the two, You add kerosene to that its just metal to metal and you will have scored all those nice soft bearing shells ! Just change oil regularly and let the filter do its work
And what if he just got the car, and it’s oil is disgusting (like this) and you suspect that sludge may be in the oil galleries and the cam phasers and actuators ? Then as long as the engine doesn’t start, there’s really no pressure on the crank bearing and only valve spring pressure (indirectly) on the cam bearings. The vast majority, even of quality mechanics are simply NOT going to pull apart the entire engine to try and save a cheap car, but this might do it. There are lots and lots of cars that already weren’t taken care of, too late to lecture about timely oil changes for those cars.
I've actually seen people do this, I know of a farmer that buys old Massey tractors like from 50s if engine is free first thing he'd do is add 50/50 oil to diesel the diffence is insane its like it makes the oil wetter and you wanna talk about bad looking oil he wouldn't run the engine just turn it over put a blow torch to pan from a distance. I'd never do it in my own Audi, my method is if there's thick gunky oil or extremely black I'd change the oil/filter once a month for 3 months and continue on every 4000, or 9 months.
Good oil prevents oil sludge buildup. I have 385,000 miles on my truck, use full synthetic oil, change it at 12,000 mile intervals, have it analyzed, and I never had a sludge problem. Oil analysis always comes back good with the advice that I could go even longer before replacing the oil.
The most oil analysis ive ever done went to the extent of cutting the filter open and running a magnet through the drained oil... why would you send the oil off to a lab for an engine with 385,000 godamn miles on it in the first place tho? Yea a motor needs good oil to keep a truckin and will prevent it from killing itself but there are other things that can kill a motor that has had oil changes every time needed..
@@Z-Ack because I bought it new and have a record of the oil conditions throughout the engines life. The analysis includes the bearing metals so you can see which bearings are wearing the most by the amounts detected. For $20 it's worth it to me. Satisfies my curiosity.
@jerrygraves6531 can't remember off hand but I'll get back to you on it. I'm busy doing farm chores right now. BTW, the engine now has 450,000 miles on it.
Back in the 60's the 82nd Airborne would add a half pint of auto transmission fluid to the crankcase for the last 100 miles or so. The motors were spotless when torn down finally. AT fluid is highly detergent but a superb lubricant. No dry start.
Now they have you take samples of all fluids to a lab for analysis and then they tell you if it needs to be changed or any other enomolies. Yes I totally agree about the trans fluid. Its highly detergenated and completely safe. Its also a great way to break in a new motor. ( I learned alot from my father who was one of the best mechanics ever. Also trained & worked 63S USA.) For the skeptics about women mechanics. 😀
We do it to all our fleet of semis during the last 100 miles or so. It’s cheaper and way more effective than most products and safer. Auto tranny fluid is the best. We also use a mix of tranny fluid and paint thinner as a rust penetrate for bolts and screws.
My first car was a junkyard w126 300se, it hadn't run for years, after ceaning the tank, flushing the gas lines and cleaning the injectors and kjet filter, I decided to tackle the oil. I I drained the oil, removed the sump, cleaned out the sludge and bought the cheapest 5w30 oil, and GUD oil filter I could get my hands on. She started right up, made a bit of tapid noise but idled smoothly. At the time I didn't have a driver's licence, so I asked my dad to drive it to and from work every day for about two weeks. After the two weeks I drained the oil, again it wasn't pleasant, I spent a seventeen year olds equivalent of an arm and a leg on a Bosch oil filter and Liqui Molly's semi synthetic oil for older engines (20w50). Ran like a charm! No tapid noise, instant oil pressure. This is the best way to "flush" your engine in my opinion...
@@nolo4133 lol watch the movie light house it’s bw they end up drinking kerosene in the end bc they ran outta Liqour I think it’s called lighthouse it has the dude who played the green goblin and the vampire dude loll from twilight
Hey guys im gonna show you how to prematurely deteriorate your crank seals. So what you need is kerosene. Kerosene is pretty caustic which is ideal for doing the opposite of conditioning. And those pieces of black in the flush may just be one of those, before mentioned, crank seals just breaking down to what would be the equivalent of nibbled cheese. And voila! There you have it folks Kerosene Is rich In fatty properties which remain after the evaporation of the grease. Every time an area or piece of rubber is exposed to a kerosene mixture the rubber Is deprived of more of its strength. Eureka! We've just "F'd up" our crank seals. 👏👏👏👏
So kerosene is pretty caustic but then you say it's rich in fatty properties? Go take a crank seal and put it in a bucket of kerosene and look at it a year later and you will see no deterioration.
Petrol is neither an acid nor is it a base. pH applies to water solutions and Petrol does not dissolve in water, therefore, petrol cannot be classified as either.
Bro. I tried Marvel Mystery Oil two weeks ago in just the fuel line and after a week the power in my Jeep with 157k was noticeably improved. A lil extra kick and my mpg improved too. Gonna add Marvel on my next oil change as well to see.
Same results with Seafoam. I got a case for less than $2/bottle so I will be using that for the foreseeable future. Home Depot had a cray price on the case so I grabbed it and ran. I felt guilty. Not guilty enough to not go back 2 days later hoping there was more on the shelf at that price. No dice someone figured it out and changed the price to $8+ bottle.
As an auto mechanic I have heard of old school guys using this technique. It’s better to use a quart of transmission fluid with clean oil, granted it can be cheap oil because it’s getting immediately flushed, followed by what you generally run the vehicle on. This is my preferred method. Sure costs alittle more but only needs to be done every 10-15k miles on today’s cars.
Back in the 80's I had a vega with 140psi , it blew the filter gasket Refilled it with diesel fuel, ran it for 20 minutes, drained it refilled with oil Cleaned it right up
My GMC had 160K on it when it was sold. Replaced a leaking valve cover gasket just before sale. The inside of the valve cover and the inside of the head was spotless. Oil and filter change every 6K
@Moto Guzzi Performing a Full Volume Oil Change will get rid of that kerosene. 10-20% of the residual oil and kerosene will remain. Performing a second oil change after driving on the highway for 20 minutes and draining/change the filter will affectively remove 96-99% of the oil and contaminents. Now the fully formulated oil with all its detergents, dispersants, anti-wear additives will be able to protect your engine much better. No need for mystery oils. Finally, it is 100% safe and affective. Flushes and mystery oils are gimmicks, at worst harmful to your engine.
I'd say higher than that since the guy said he uses "synthetic oil" I use royal purple oil and filter, and only change my oil around 12,000 miles and it's NEVER looked that bad.... and the shit starts out purple to begin with
TheChemist187 I been doing that for year. A qort (nope I can't spell) of ATF about 100 miles before an oil change. I've ran a 3.9 Dakota with 4 qorts of GTX 10W-30 and 1 qort of ATF for four years. Only way I wasn't adding a qort at every red light lol! I've never had one issue. And Lord did I drive that Dakota lol.
Yup if I know my oil is starting to get bad. I put 1 quart of transmition oil to 4 quarts of oil. Run it for 3,000 miles. Always a succes on cleaning up engine.
Btw - you should ALWAYS inspect the inside of a new oil filter before installing it, because they often have metal burrs/flakes inside where the threads are machined. These flakes are on the FILTERED side, meaning they can exit the filter and go straight to the engine internals. It'd be pretty ironic if the source of the "grit" was the oil filters themselves...
Sorry but that's not entirely true it's machine before they put it together if the flakes went down inside their that is the intake side of the oil it can't get through the filter do your homework
I worked at the oil filter company making oil filters when their employees went on strike. There are not metal contamination inside bran new USA oil filters. They are made with pistons and lubricants sprayed on them threw the entire process so no metal fragments are inside oil filters!
I’ve been a mechanic for 45 years, and I just want to say, this guy is an idiot! Never do this to your car. Your ex-wife’s car? Sure. But never your own....
I was thinking on the same line you are, probably would plug your engine.Someone wrote that your oil fries at 210°F.The newer cars oil viscosity keeps getting thinner, I used to run 20w-50 in the 400m Ford engines, when I changed the engine would also put a TRW high volume oil pump. I been working on some 80's model 351Windsor HO, getting ready to take one out a1985 E-250 that has 35,000 miles and don't want to turn over after a small fire by the mechanical fuel pump.Also have 1982 1 ton duelly with 1983 351W, I been looking for another small block to put in while I rebuild the 351W HO.Carbuerated, I found a 300-6 cylinder, not sure about it yet.Still looking.
I just came for the comments. I was not disappointed lol. Your wife's hands look great turning the key. Can you qualify how many people is a lot. I have been around cars my whole life and have never seen anybody remove a pan to remove sludge.
Whatever is in the sump will stay in the sump, the oil pump will pick up oil and send it thru the filter which will catch the smaller bits. The bigger bits will stay on Tue bottom of the sump. You may save some wear on the oil pump but like many comments here... Just change your oil regularly and use a good filter and you're good.
In the early 80s the old-timers would drain the oil, leave the old filter on and pour in a 50/50 mix of diesel and kerosene, then run the engine for 20 minutes These guys used their pickups every day to check their wells here , and these pickups would run 8 to 10 hours a day continuously 7 days a week. When we would tear em down they were surprisingly clean, especially the ones that ran on propane,. 90 percent of the time the reason for the rebuild was wore out oil pumps and plastic timing chain gears.
I did that engine flush with a car I had bought. Never again. Looked great at first with all the crap that came out but about 3 months later all the other crud that started breaking lose but did not come out at first stoped up the pickup tube. Don't short cut, drop the oil pan and valve cover and remove that way.
Years ago a friend did something similar except he changed the oil minus one quart and added 1 quart of Kero. He would then run it for about 20 minutes and replace the oil with fresh oil. Never had any issues with his engine and makes sense since you never run the engine with no oil and Kero is distributed throughout under pressure.
But that seems more sane.Dilluting the oil just makes more sense. You are atleast providing protection. But pure kerosine seems like a horrible idea to me.
Your methods may be effective and are well intended. I agree that removing contaminants from an engine is beneficial. However, those pieces (and grit) you show typically don't circulate through the engine and remain in the pan. If they are lifted by the oil pump, then the oil filter will trap them before going through the motor. (Viewers please lookup the filtering efficiency at stated particle size of the oil filter you currently use.) Many will believe that the motor medic flush you showed to be 'basically' kerosene, when in fact its mostly mineral oil with a lesser percentage of kerosene (look up the SDS on the product) because kerosene has little to no lubricity. The fear that viewers may intentionally use straight kerosene as they would the motor flush you showed may be misinterpreted and is real. The average backyard mechanic may not wish to pull a fuse to perform this, and potentially may cause damage by idling the engine until the oil is hot. Keep in mind, in your process there is kerosene left in oil passages through out the motor and this of course will stay with the new oil. This may not be desirable.
If you get kerosene hot enough (well within the normal operating temperature on some components) it can become quite volatile with deadly and catastrophic results. Kerosene has a Flashpoint between 100 and 150F and everything under the hood of your car is usually over 100F. Now it doesn't necessarily combust at 150F, but it's not real hard to get it to combust at that temperature. When I feel compelled to flush an automotive crankcase, I drain the oil, refill with ATF, let it idle 5 to 10 minutes, drain the ATF, replace the oil filter and refill with the correct viscosity motor oil. Some might call me crazy, but at least I'm not putting light volatiles in a pressurized crankcase and then heating it up. Lol
On older cars that I have owned; I drain the old oil, replace oil plug, fill up with ATF and run on idle for 20 minutes. Drain, add new oil and new filter. You can also add half a quart of ATF with new oil change and drive for 100- 300 miles to build up oil pressure. ATF does an excellent job @ removing sludge safely as its petroleum oil and it doesn't remove too much sludge or deposits. Gotta be careful not to clog your oil screen.
I agree with most of what you said. But IMO i would not want to run an engine with ATF in the oil, for any longer than 15 to 30 seconds, if even that long. Then I'd drain the oil, change the filter, and refill with some cheap oil to do a "rinse" and run the engine for 15 - 20 minutes. And drain and refill for good, after that. I just have a problem with running the engine with ATF or other solvents in the oil, it seems very counter-productive.
I don't like the idea of pouring kerrosine into the engine , why don't you just change the oil , run it for fifty miles and change it again , I'd consider this to be much safer for my engine .
Jaber Jaber eeemmm thats not how any of this work, to get the grit out of the engine u have to remove oil pan, lucky my audi has a very simple oil pan and does not need a front axel to be removed like most cars do.
Jaber Jaber , use marvel mystery oil. put one qt when your oil level goes down one. Drive with mmo for a couple of days then change oil and filter. Does a good job plus it removes varnish from the rings. Your engine will run smoother and regain its power.
You are right. I change mine every 5,000 and I use high quality oil and filter. Mine has never looked that dark and I don't get any of that other crap coming out of my engine either.
Any oil is better than no oil, and Any sluge can and will cause problems. A 92 volvo that sat and seized over a two year period will definitely have more sluge in the pan and filter, and using the kerosene to free up the stuck motor is just the ticket. I just use the drill and socket to spin the intermediate shaft to pump the mixture into the engine. A new filter is used to catch any mung, Goin to the engine passages. And any contamination release is going to sit in the oil pan. So flushing it out seems like a no brainer to me. I would also pump some cheap oils through to remove the kerosene, replace the filter and add fresh oil, and see if I can get another quarter million miles out of this 240 volvo.
Don't do it. Kerosene is very dry and will strip any remaining lubricant from the working surfaces and it wil damage and dry the seals, causing them to leak. Put about 1/2 pint of diesel in the hot engine before draining the old oil out, let it idle for about 10 mins. (don't drive it) then drain the oil. I have worked on Audis, and they are very prone to sludging; make sure you use a fully synthetic oil and change regularly, more often if they are doing short trips or in adverse weather conditions.
Madness , a good quality engine flush has a lubricant added , also it cleans out the scraper rings equalizing compression and cleans oil galleries and any sludge through the entire motor .
There is why I don't have that problem. I never ever buy Fram filters. Not even the supposedly good Fram filters. I only use Mann filters or Purolator. My car takes a cartridge type filter so there is no hiding bad quality inside a metal can, you can see it for yourself before you put it in there. Then when you change the oil you can see how very well it held up.
@@charleshines6155 you are a man of my own heart, I only will use Mann or in a pinch Purolator in my Bmw or Porsche. Same with my wife's Mini. Never had a filter come apart or not trap everything. Also german cars use cartridge type filters for a reason, so you or your mechanic can check for anything severe happening in your engine like abnormal wear resulting in metal fragments, even seal fragments. In an enclosed spin on filter you would need to cut the filter in two.
@@brandonbentley8532 I bought a Purolator for my Passat and it is the one without the metal can. It looks identical to the Mann filter and is even made in Germany, Oddly the Mann filter for that car is now made in Mexico but I used to see them from Germany. Mann Hummel bought Purolator. The Purolator Boss filter is a white media and close in price to the Mann filter sometimes. Other than the color of the media the two filters are identical. My car is a 2013 Passat 2.5.
One question - isn't the oil filter supposed to filter out all this grit to stop it from circulating around the engine when it filters out the engine oil?
I'm no mechanic but I cringed at the kerosene. But he is worried about his engine oil being dirty and goes through the whole process and then before replacing the oil he puts a fram filter on it. WHAT?! Fram? Its barely even a filter. No wonder why you have sludge in your car because you're basically not using a filter at all. For those that use Fram, crack one open and see what's inside. Geez.
All that grit in your oil would be a fundamental failure of your oil filter. Likely picked it up from the catch pan or something falling in the catch pan from under the car. Also, not sure those short cranks fully circulate the kerosene which is why a good flush like liqui moly pro flush is a better choice.
Good decision. Just reading through these comments I've read like 25 good reasons why this is a terrible idea the one that popped up my head immediately is the effect of kerosene on rubber seals I mean any type of solvent on rubber is a terrible idea.
I have a GDI engine....mother of all sludge building engines. I change my oil every 1500 miles to keep on top of the build up. Engine runs alot smoother keeping the oil clean.
Removed the pan on my engine with over 250,000 miles. It was clean. I took the valve cover also it was clean. I used good oil and changed it regularly. Use a high grade oil filter. I wonder if it could be flammable. Being that it is so thin could it pass thru the rings and clog the O2 sensors. I will stick with my way. I would never use engine oil cleaner either. Waste of money. Rebuilt a few motors . Only thing that cleans the oil pump sump is if you take it out.
how is the grit forming? Also should not the oil filter be blocking this grit going back into the enigne? it looks too big not to be blocked by the filter.
That grit is usually dirt and not something inside your engine. Using transmission fluid is a better way of removing sludge due to it's high detergency but won't thin out your oil nearly as much as kerosene. If you keep up with oil changes there won't be any sludge and if you need to flush out your engine, it means it wasn't well maintained so flushing it out will only make it worse. And if the car you're looking to buy NEEDS an engine flush, it wasn't maintenanced properly so why buy it?
How do you remove the kerosene 100‰ later on to avoid mixing up with the new engine oil? This is not good for long term because the kerosene still be around even if u drain completely unless u open up the engine and use pressure jet to remove it
This works great by the way. Had a 350,000 mile 5.3L chevy look almost Brand new on the inside said the mechanic that put in all new gaskets and oil pump along with a transmission at the time. Did the cleaning at the 250,000 mile point.
5.3L chevy LS "vortec" engine will often go to 350,000 miles if maintained well. A good synthetic or high mileage oil has detergents and anti-foaming agents in then which will clean the carbonized oil "sludge" out of the engine over time. This idiot is putting and pumping kerosene into an engine that also supplies oil to the bearing in his turbo. This guy is an idiot and should not be listened to. If you want to mix something into your oil to help with sludge use a half quart of ATF (automatic transmission fluid). You don't need any special kind since I highly doubt you had an L33 aluminum block 5.3L. You're best off just using a quality oil filter and royal purple oil and change them regularly. I dont know what you drive now but if you want to keep it running good then dont try to lubricate the friction surfaces with a strong solvent like kerosene. Just an FYI. Gotta love those LS engine though.
Dave here from southern Australia….If you are weird about your oil being contaminated just change your oil filter twice during your cycle…Full synthetic always 5w30 12.000 Kay’s never a drama 🎭 ROYAL PURPLE
this has been done since the 50's, it does work but you have to not be silly. why way back in the 50's+? cuz motor oil used to not have alot of detergents in them.
@@TheFunkymohawk nope... Wix, aka Napa gold filters, are far superior to FRAM. I used to use FRAM and changed every 3k and my oil always looked as dark as the oil in this video. Just went almost 10 with a wix because every time I checked the oil it looked clean! I've always used synthetic oil. I swore off FRAM after one nearly destroyed my phasers...
Do you think the kerosene is actually going to unclog a pick up screen? I was trying to liqui-moly and it did not cure my little oil pressure from a clogged screen
I like the toothbrush ideal, I've seen many oil screens and they are mostly all clogged up. If you are able to reach it with a toothbrush then that's a great idea! Also use a magnetic drain plug to pick up fine pieces of metal.
Magnetic drain plug for modern engines doesn't do much since blocks are made from mostly aluminum these days meaning nothing is magnetic to begin with. When iron blocks were common, yes, using a magnetic drain plug would help.
@Lwnmwrboy5 it's not the blocks that the magnetic drain plugs are used for. It's to collect bearing material which is in every block not matter what it is cast from. And all bearings wear over time not matter how well you take care of the engine.
+William Poetra Yoga You do bring up a good question. It is possible that if you crank a starter over and over and over that it would overheat and damage the starter motor. In this particular case I took the starter over a small amount and then give it a break. I have definitely been in that situation where a car will not start and I am cranking it hoping that the car will start soon and in my mind I know that the starter is getting a work out more than it should. In those cases I have put my hand on or near the starter to see if it is overheating. Luckily I have found that the battery will usually be dead before you overheat the starter. What would really be bad for the starter would be to change the battery and keep cranking heavy on the starter. When I was using the starter to crank the engine over in the video are used many small Kranks to move the kerosene through the engine. From experience I did not feel that I was putting an extreme load on the starter. Of course the reason I was using the starter to move the kerosene through the engine was to keep the Pistons moving slow so there would be less wear and tear on the piston rings and the piston walls. I have known people to run the engine with kerosene in the engine without a problem, I'm just being a little more conservative. So the thought I would leave you with is, if you crank The engine with the starter motor make sure that your starter motor does not get hot. If it does get hot let it rest and cool off. I still feel better about giving the starter a bit of a work out rather than running the engine with kerosene instead of oil. I hope I answered your question, please feel free to ask any other questions. Thank you again for your comment.
Will wear it out MUCH faster...if you must...crank for 10-15 seconds continuous...then let it cool for 10-15 min...bumping it like that stresses the contacts and can burn the solenoid contacts
ATF fluid also works very well. You can substitute one quart of oil with it and drive normally on it untill your next oil change. My auto instructor did it all the time.
USED KEROSENE for 35 years on all my vehicles, Fords, Dodges, all kinds all types and never had problems w shavings. Never had any pinging, clicking, or damage, with long life to the motor. New Filters often have thread shavings on them, check your filters. Its also based on how often you do this and also what kind of oil you use, and running the kerosene thru until it cleans the oil pan. All oils allow for some metal wear, cheap oil will shave your motor more, good synthetic not as much.
Been using 1 bottle of marvel mystery in all my vehicles every other oil change. I'm a betting man that I've owned less vehicles and internally problematic engines than 90% of the people commenting. Just change your oil on time along with a quality filter.
Also, do not use the kerosene/motor flush trick on an old engine. the sludge inside is sealing off holes that are in your gaskets and other greasy spots, only do this as a last resort! and another note, after flushing your engine, pull the oil pan to clean off potential sludge/junk that might get sucked up in the oil pick-up tube.
Not really, I rebuilt starters for a while and in my experience it was the long cranking that over heated the starter due to heat cause the persons car would not start, or just old age
Randizle Peregoy i agree. Had put in a new started on a old 4cyl wagon and one day flooded steets got water got on the ignition system since i was missing splash shields and cause the engine to die out and i tried to start the engine over and over again since i was in a bad spot trying to get it started. Held the starter on for about 10 sec each attempt. Eventually draining the battery. Ever since then, the starter acts funny from time to time by not activating when the key is turned.
I wiped out the rod bearings on my 1954 Hudson using this method and the same thing happened to my friends 1951 Merc.This is an old school method that has been passed down for years.that can do major damage to your engine.BEWARE!!
Yup, it's safer to add 1 or 2 cups of kerosene to the old oil in the engine and run at idle then stop, drain and change the oil filter. I'd never put 100% kerosene in an engine!
@@illuminatedzach4206 It gets out a lot of grit, all of it? we'd never know, but I find that the sludge on the inside of the rocker covers is gone, etc. If you have a vintage car, sludge & blow by is common, if you have a 2000s + car and take car of it, there won't much awful grit to get rid of. Don't over-do it, like 100% kerosene or damaged crankshaft seals will occur!! Good luck!
krazor8 he poured kerosene in it whet did you think would happen that's what makes his oil look like that You can never get all that stuff out don't care how long you let it drain. Marvel mystery oil works better You can driv around for 20
Oh he accomplished something, he managed to break loose all the deposits from prior lack of maintenance and now is likely to do more damage than otherwise would have been done. Especially with a junk fram filter with the cardboard bypass. If someone tries this on a newer car with variable valve timing they will be taking their vehicle to a shop to have the vvt actuator replaced after the orifice inside gets plugged with sludge. Just leave it alone, the damage is already done.
I would like to add, i have tried this method number of times, instead of cranking the engine 50 times, i used to do it 2-3 times only without letting the engine start. In end, i used to blow pressurized air from inlet and have the remaining Kerosene come out from drain with pressure as that would make sure that non is left inside. This method works and you can feel the difference on your engine running smooth. Many people would disagree with the method, its their own choice but this works well.
Oil filters are for this very purpose. Oil that darkens in colour (UK spelling) is doing its job keeping contaminants in suspension. I agree that some of the 20,000 - 30,000 mile oil change intervals are probably slightly ambitious but there's no need to flush in the way shown here.
not so much, diesel works well too. HOWEVER, i don't recommend you turn your car over 50 times in a row as he does. nice way to need a new starter soon.
Mechanic here. I can't even begin to list all the things wrong with this. That "grit" is the metal shavings caused by using kerosene.
Pro tip: Change your oil at the proper interval and use a quality filter. You will be fine.
I've been a mechanic for almost 30 years and I cringe when I see people doing a flush like this. All that grit is going through your oil pickup and pump and all of your galleries. I've seen peoples oil pump pickup come out so clogged you cant even see the screen

I used to be a GM mechanic at a Chevrolet dealership and had a local mailman who owned a 1972 Impala with a 454 in it We did all of his oil changes and he always demanded 6 quarts of oil and 1 quart of ATF.

Just change your oil and filter on time or little earlier, and also use high quality oil and filter, use the right type of oil grade, type and amount, as well as proper oil filter, and it will run good for long time.
I don't know what the negatives will end up being from this, but even really sludgy engines are usually cleaned up by using premium synthetic oil with relevant additive packages. For example, Mobil 1 High Mileage just indicates to do a few shorter.oil change intervals so the oil can slowly and safely dissolve deposits into solution for removal during the drain.
And it works quite well.
@@miguelquazar883 You mean cleaning with the Mobile one high mileage? I never used it but if it cleans up deposits...
Do not use mobil one high milage it's recycled oil. Be sure to go for mobil one full synthetic. It has the proper additives for your engine
The grit you have found is in the pan and does not enter the engine oil galleries. This is the sump reservoir that delivers oil to the filter. The filter prevents this debris from entering the engine. If you feel compelled to flush this debris, then pour the kerosene down the dipstick tube with the drain plug removed and capture the kerosene in a container. This will prevent the kerosene entering the engine, diluting the new engine oil, and causing a dry start after the oil change.

I use a quart of Marvel mystery oil a few days before I do my oil change. I never get sludge buildup and it cleans lifters and piston rings quite affectively. I’ve tried this technique for 40 years and as an engine builder

I add a quart of MMO to my engine after a new oil change. I don't believe having an extra quart in the crankcase of a 6 quart engine hurts anything. I change at 3000 miles. Never had a problem.
My Grandpa used Marvel,my Dad used it and I do the same, Great way to keep things clean inside
I love sludge, it keeps the old car from leaking alot of oil.
Gotta say, you gave me a good laugh. You get a thumbs up from me.
It help things keep from rusting to lol
In older engines this is actually true. The sludge acts as a seal for all the bearings. That's why you should never clean out your oil like that or even with oil circuit cleaner in an older engine.
There are also CONs for this in newer engines with VVT and things like that. As long as you have no problem, don't try it. The cleaner might release grit and sludge, which can go into your VVT solenoids or similar things and block them.
That is true. I have heard that with transmission Flushes. Only change what's in the pan. Ya don't wanna empty out a transmission of all or alot of it's fluid because all the new fluid with all it's detergents will clean all them old ass seals up & all those old ass clutchs out and pretty soon it's leaking & a slipin'. If ya go puttin a solvent in yer oil then YEP it's gonna clean the hell outta some seals & bearings. Not to mention help all the sludge & gunk travel thru the rest of your engine. But wtf do I know. I'm just am old Hellbilly. Hahaa
As a journeyman HD mechanic I'm horrified. If you want to destroy your engine and starter this is the quickest way to do it. There are pickup screens before the oil pump and a filter in the circuit. Rotating your engine with kerosene as a lubricant will destroy your mains and valvetrain. This completely disregards oil wedge theory and points to sludge as the cause of most engine failures, not true. Don't do this, bad idea. Also, engine oil gets dark because it has detergents in it, most large diesels will have jet black oil after 30mins of running. Color of oil is less important than viscosity and acid content(or total base number). The creator of this video is not posting proven maintenance techniques.
Your 1000 percent correct. I'm horrified as well.
This is truly unconventional.....
May be a fast way to remove such slug,but certainly a fast destructive technique.
Which is the best way of removing sludge except using detergent like kerosene and engine flush

Why not swap the entire engine ? Then change the oil on a daily basis. Think of all the gratitude you will receive from the oil companies?
But a new car, fill the old one with grit.
I know this is slightly off topic,but I've used Fram oil filters for years until I saw a video with the guy who cut open 4 or 5 popular filters to show how much filter material is inside. Fram failed miserably,but Napa & Wix rated the highest. Needless to say, I paid a few bucks more for the wix,but it's worth it!
Hes gonna start that car and that engine is gonna say, take the BUS.
Your big end shells are made of a very soft material and have a grove cut in them ! The grove fills with oil so that your crankshaft etc are actually not touching any other metal surface ! ie there is a fine film of oil in-between the two, You add kerosene to that its just metal to metal and you will have scored all those nice soft bearing shells ! Just change oil regularly and let the filter do its work
And what if he just got the car, and it’s oil is disgusting (like this) and you suspect that sludge may be in the oil galleries and the cam phasers and actuators ? Then as long as the engine doesn’t start, there’s really no pressure on the crank bearing and only valve spring pressure (indirectly) on the cam bearings. The vast majority, even of quality mechanics are simply NOT going to pull apart the entire engine to try and save a cheap car, but this might do it.
There are lots and lots of cars that already weren’t taken care of, too late to lecture about timely oil changes for those cars.

I'd never do it in my own Audi, my method is if there's thick gunky oil or extremely black I'd change the oil/filter once a month for 3 months and continue on every 4000, or 9 months.
Good oil prevents oil sludge buildup. I have 385,000 miles on my truck, use full synthetic oil, change it at 12,000 mile intervals, have it analyzed, and I never had a sludge problem. Oil analysis always comes back good with the advice that I could go even longer before replacing the oil.
The most oil analysis ive ever done went to the extent of cutting the filter open and running a magnet through the drained oil... why would you send the oil off to a lab for an engine with 385,000 godamn miles on it in the first place tho? Yea a motor needs good oil to keep a truckin and will prevent it from killing itself but there are other things that can kill a motor that has had oil changes every time needed..

AT fluid is highly detergent but a superb lubricant.
No dry start.
Now they have you take samples of all fluids to a lab for analysis and then they tell you if it needs to be changed or any other enomolies. Yes I totally agree about the trans fluid.

I I drained the oil, removed the sump, cleaned out the sludge and bought the cheapest 5w30 oil, and GUD oil filter I could get my hands on. She started right up, made a bit of tapid noise but idled smoothly. At the time I didn't have a driver's licence, so I asked my dad to drive it to and from work every day for about two weeks. After the two weeks I drained the oil, again it wasn't pleasant, I spent a seventeen year olds equivalent of an arm and a leg on a Bosch oil filter and Liqui Molly's semi synthetic oil for older engines (20w50). Ran like a charm! No tapid noise, instant oil pressure. This is the best way to "flush" your engine in my opinion...

Hey guys im gonna show you how to prematurely deteriorate your crank seals. So what you need is kerosene. Kerosene is pretty caustic which is ideal for doing the opposite of conditioning. And those pieces of black in the flush may just be one of those, before mentioned, crank seals just breaking down to what would be the equivalent of nibbled cheese. And voila! There you have it folks Kerosene Is rich In fatty properties which remain after the evaporation of the grease. Every time an area or piece of rubber is exposed to a kerosene mixture the rubber Is deprived of more of its strength. Eureka! We've just "F'd up" our crank seals. 👏👏👏👏
All very true!
So kerosene is pretty caustic but then you say it's rich in fatty properties? Go take a crank seal and put it in a bucket of kerosene and look at it a year later and you will see no deterioration.
@@William1866 Kerosene is a similar ph to petrol.
Petrol is neither an acid nor is it a base. pH applies to water solutions and Petrol does not dissolve in water, therefore, petrol cannot be classified as either.
Your exactly right.
Use Marvel Mystery Oil regularly. At oil change intervals and add to gas now and then at fill up. You'll notice the difference!

As an auto mechanic I have heard of old school guys using this technique. It’s better to use a quart of transmission fluid with clean oil, granted it can be cheap oil because it’s getting immediately flushed, followed by what you generally run the vehicle on. This is my preferred method. Sure costs alittle more but only needs to be done every 10-15k miles on today’s cars.

@Moto Guzzi Performing a Full Volume Oil Change will get rid of that kerosene. 10-20% of the residual oil and kerosene will remain. Performing a second oil change after driving on the highway for 20 minutes and draining/change the filter will affectively remove 96-99% of the oil and contaminents. Now the fully formulated oil with all its detergents, dispersants, anti-wear additives will be able to protect your engine much better. No need for mystery oils. Finally, it is 100% safe and affective. Flushes and mystery oils are gimmicks, at worst harmful to your engine.

Atf is a 5w20 base oil with a ton of additives and detergent. Has a ton more film strength than kerosene.
Btw - you should ALWAYS inspect the inside of a new oil filter before installing it, because they often have metal burrs/flakes inside where the threads are machined. These flakes are on the FILTERED side, meaning they can exit the filter and go straight to the engine internals. It'd be pretty ironic if the source of the "grit" was the oil filters themselves...
Years ago that was common, much better noe
Sorry but that's not entirely true it's machine before they put it together if the flakes went down inside their that is the intake side of the oil it can't get through the filter do your homework

Whatever is in the sump will stay in the sump, the oil pump will pick up oil and send it thru the filter which will catch the smaller bits. The bigger bits will stay on Tue bottom of the sump.

Years ago a friend did something similar except he changed the oil minus one quart and added 1 quart of Kero. He would then run it for about 20 minutes and replace the oil with fresh oil. Never had any issues with his engine and makes sense since you never run the engine with no oil and Kero is distributed throughout under pressure.
But that seems more sane.Dilluting the oil just makes more sense. You are atleast providing protection. But pure kerosine seems like a horrible idea to me.
😂that's the instructions on the bottle🤦♂️
Your methods may be effective and are well intended. I agree that removing contaminants from an engine is beneficial. However, those pieces (and grit) you show typically don't circulate through the engine and remain in the pan. If they are lifted by the oil pump, then the oil filter will trap them before going through the motor. (Viewers please lookup the filtering efficiency at stated particle size of the oil filter you currently use.) Many will believe that the motor medic flush you showed to be 'basically' kerosene, when in fact its mostly mineral oil with a lesser percentage of kerosene (look up the SDS on the product) because kerosene has little to no lubricity. The fear that viewers may intentionally use straight kerosene as they would the motor flush you showed may be misinterpreted and is real. The average backyard mechanic may not wish to pull a fuse to perform this, and potentially may cause damage by idling the engine until the oil is hot. Keep in mind, in your process there is kerosene left in oil passages through out the motor and this of course will stay with the new oil. This may not be desirable.
thanks for the insight
If you get kerosene hot enough (well within the normal operating temperature on some components) it can become quite volatile with deadly and catastrophic results. Kerosene has a Flashpoint between 100 and 150F and everything under the hood of your car is usually over 100F. Now it doesn't necessarily combust at 150F, but it's not real hard to get it to combust at that temperature. When I feel compelled to flush an automotive crankcase, I drain the oil, refill with ATF, let it idle 5 to 10 minutes, drain the ATF, replace the oil filter and refill with the correct viscosity motor oil. Some might call me crazy, but at least I'm not putting light volatiles in a pressurized crankcase and then heating it up. Lol

On older cars that I have owned; I drain the old oil, replace oil plug, fill up with ATF and run on idle for 20 minutes. Drain, add new oil and new filter.
You can also add half a quart of ATF with new oil change and drive for 100- 300 miles to build up oil pressure. ATF does an excellent job @ removing sludge safely as its petroleum oil and it doesn't remove too much sludge or deposits. Gotta be careful not to clog your oil screen.
I agree with most of what you said. But IMO i would not want to run an engine with ATF in the oil, for any longer than 15 to 30 seconds, if even that long. Then I'd drain the oil, change the filter, and refill with some cheap oil to do a "rinse" and run the engine for 15 - 20 minutes. And drain and refill for good, after that.
I just have a problem with running the engine with ATF or other solvents in the oil, it seems very counter-productive.
I don't like the idea of pouring kerrosine into the engine , why don't you just change the oil , run it for fifty miles and change it again , I'd consider this to be much safer for my engine .
Jaber Jaber what works is adding a quart of diesel to the oil and running the engine
Jaber Jaber eeemmm thats not how any of this work, to get the grit out of the engine u have to remove oil pan, lucky my audi has a very simple oil pan and does not need a front axel to be removed like most cars do.

Jaber Jaber , use marvel mystery oil. put one qt when your oil level goes down one. Drive with mmo for a couple of days then change oil and filter. Does a good job plus it removes varnish from the rings. Your engine will run smoother and regain its power.
Jaber Jaber : Thanx for a good idea!
Put magnets on the oil filter!! Works good
I think the filter will catch the metal just fine.
@@guidedbygreen1480 Unless the filter goes in to bypass which actually happens more often than most people realise
He claims to change his oil whenever he sees the oil getting dark but his own video shows he waits until its black af lol
I was thinking the same lol
Lmao, true!
You are right. I change mine every 5,000 and I use high quality oil and filter. Mine has never looked that dark and I don't get any of that other crap coming out of my engine either.
Exactly 5k miles still a golden honey color.
I saw it and was wondering what the heck he could do to make oil that bad in 3K miles????
Any oil is better than no oil, and Any sluge can and will cause problems. A 92 volvo that sat and seized over a two year period will definitely have more sluge in the pan and filter, and using the kerosene to free up the stuck motor is just the ticket. I just use the drill and socket to spin the intermediate shaft to pump the mixture into the engine. A new filter is used to catch any mung, Goin to the engine passages. And any contamination release is going to sit in the oil pan. So flushing it out seems like a no brainer to me. I would also pump some cheap oils through to remove the kerosene, replace the filter and add fresh oil, and see if I can get another quarter million miles out of this 240 volvo.
Hehe, that grit brother isn't sludge, it's engine ring fragments! Sludge is thick gooey carbon buildup, not grit.
he never said the grit was sludge.
@@vaquero3578 thats the point, you dont put this in to remove "grit" you put it in to remove sludge.
Don't do it. Kerosene is very dry and will strip any remaining lubricant from the working surfaces and it wil damage and dry the seals, causing them to leak.
Put about 1/2 pint of diesel in the hot engine before draining the old oil out, let it idle for about 10 mins. (don't drive it) then drain the oil.
I have worked on Audis, and they are very prone to sludging; make sure you use a fully synthetic oil and change regularly, more often if they are doing short trips or in adverse weather conditions.
I use diesel on my Chevrolet blazer 2001, I put about 1/2 pint of diesel on the engine before remove the old oil and it works just fine......
@Mark Stuckey do you mean put 1/2 pint of kerosene in the engine, before change the old oil?
@@leonardussamderubun986 No, no, no. not kerosene. Diesel.
Put small amt of diesel in a premium oil tank before oil change? That takes care of sludge?
Madness , a good quality engine flush has a lubricant added , also it cleans out the scraper rings equalizing compression and cleans oil galleries and any sludge through the entire motor .
Could just be chunks of the cheap fram oil filter you’re using! Kerosene=seal failure
There is why I don't have that problem. I never ever buy Fram filters. Not even the supposedly good Fram filters. I only use Mann filters or Purolator. My car takes a cartridge type filter so there is no hiding bad quality inside a metal can, you can see it for yourself before you put it in there. Then when you change the oil you can see how very well it held up.
@@charleshines6155 you are a man of my own heart, I only will use Mann or in a pinch Purolator in my Bmw or Porsche. Same with my wife's Mini. Never had a filter come apart or not trap everything. Also german cars use cartridge type filters for a reason, so you or your mechanic can check for anything severe happening in your engine like abnormal wear resulting in metal fragments, even seal fragments. In an enclosed spin on filter you would need to cut the filter in two.
@@brandonbentley8532 I bought a Purolator for my Passat and it is the one without the metal can. It looks identical to the Mann filter and is even made in Germany, Oddly the Mann filter for that car is now made in Mexico but I used to see them from Germany. Mann Hummel bought Purolator. The Purolator Boss filter is a white media and close in price to the Mann filter sometimes. Other than the color of the media the two filters are identical. My car is a 2013 Passat 2.5.
One question - isn't the oil filter supposed to filter out all this grit to stop it from circulating around the engine when it filters out the engine oil?
Depending on how the oil system works
Will the residual kerosene that didn’t come out, degrade the oil when you fill the oil? Both regular and synthetic. Thanks for the video
Yes
*Fills engine with kerosene*
*Also puts a fram filter on it.*
“I know car tricks you don’t”
🤦♂️
"Look at this sludge" holding up fragments of big end bearing lmao. dear god no one ever do this.
@@AskAboutMyZombiePlan I think they were ring fragments but yeah, more steel in the case then in the engine. That engine has got to be toast by now.
I'm no mechanic but I cringed at the kerosene. But he is worried about his engine oil being dirty and goes through the whole process and then before replacing the oil he puts a fram filter on it. WHAT?! Fram? Its barely even a filter. No wonder why you have sludge in your car because you're basically not using a filter at all. For those that use Fram, crack one open and see what's inside. Geez.
Fram is the crappiest filter on the market
Anything but that "Fram" filter, I believe by far, that's the worse oil filter on the market. I certainly won't use it, it's low quality at It's best.
Start your starter 50x in such short timing and you'll need to replace that starter as well.
@Leo Coffy 🤣🤣🤣
thats what I was thinking ... better to just run it for a minute or two
@Leo Coffy 😂😂🤣
ehehehee
How about a quart of Marvel Mystery oil before changing the oil and let it run for ten minutes. then drain.
All that grit in your oil would be a fundamental failure of your oil filter. Likely picked it up from the catch pan or something falling in the catch pan from under the car. Also, not sure those short cranks fully circulate the kerosene which is why a good flush like liqui moly pro flush is a better choice.
He got like 4 specs of dirt out that thing 😂😂😂😂
slabbinonspokez z 😂😂😂
I've found after the 2k mark on the odo the trade in method works the best for those peskey carbon buildup and sludge issues.
there's something therapeutic and satisfying about flushing a motor and putting clean oil back in it
Lmfao not gonna try that ever
Jeremy Cole lol...right?! 😲
Jeremy Cole specially on a damn Audi.
Best April fools joke ever!
Jeremy lmao I said the same thing
Good decision. Just reading through these comments I've read like 25 good reasons why this is a terrible idea the one that popped up my head immediately is the effect of kerosene on rubber seals I mean any type of solvent on rubber is a terrible idea.
I have a GDI engine....mother of all sludge building engines. I change my oil every 1500 miles to keep on top of the build up. Engine runs alot smoother keeping the oil clean.
Removed the pan on my engine with over 250,000 miles. It was clean. I took the valve cover also it was clean.
I used good oil and changed it regularly.
Use a high grade oil filter. I wonder if it could be flammable. Being that it is so thin could it pass thru the rings
and clog the O2 sensors. I will stick with my way.
I would never use engine oil cleaner either. Waste of money.
Rebuilt a few motors . Only thing that cleans the oil pump sump is if you take it out.
james37603 not true.
Thank you, thank you Forrest Gump. Mama would be so proud.
Hahahahahaha exactly Mr. Gump
how is the grit forming? Also should not the oil filter be blocking this grit going back into the enigne? it looks too big not to be blocked by the filter.
That grit is usually dirt and not something inside your engine. Using transmission fluid is a better way of removing sludge due to it's high detergency but won't thin out your oil nearly as much as kerosene. If you keep up with oil changes there won't be any sludge and if you need to flush out your engine, it means it wasn't well maintained so flushing it out will only make it worse. And if the car you're looking to buy NEEDS an engine flush, it wasn't maintenanced properly so why buy it?
Someone else mentioned using transmission fluid in the crankcase as well to remove sludge before an oil change. Seems to be an effective technique.
watch project farm atf is not a good substitute for flushing
significant wear
It was a great technique for destroying the bottom end of my buddy's 350 Vortac engine. lol
How do you remove the kerosene 100‰ later on to avoid mixing up with the new engine oil? This is not good for long term because the kerosene still be around even if u drain completely unless u open up the engine and use pressure jet to remove it
This works great by the way. Had a 350,000 mile 5.3L chevy look almost Brand new on the inside said the mechanic that put in all new gaskets and oil pump along with a transmission at the time. Did the cleaning at the 250,000 mile point.
5.3L chevy LS "vortec" engine will often go to 350,000 miles if maintained well. A good synthetic or high mileage oil has detergents and anti-foaming agents in then which will clean the carbonized oil "sludge" out of the engine over time. This idiot is putting and pumping kerosene into an engine that also supplies oil to the bearing in his turbo. This guy is an idiot and should not be listened to. If you want to mix something into your oil to help with sludge use a half quart of ATF (automatic transmission fluid). You don't need any special kind since I highly doubt you had an L33 aluminum block 5.3L. You're best off just using a quality oil filter and royal purple oil and change them regularly. I dont know what you drive now but if you want to keep it running good then dont try to lubricate the friction surfaces with a strong solvent like kerosene. Just an FYI. Gotta love those LS engine though.
This video turns magical in 1.25x speed.,..... Try it 😀
2x is better
I've known people put in a quart of transmission fluid just before changing oil but I've never heard of using kerosene.
Dafuq,why transmission oil?
Is this a joke?
Dave here from southern Australia….If you are weird about your oil being contaminated just change your oil filter twice during your cycle…Full synthetic always 5w30 12.000 Kay’s never a drama 🎭 ROYAL PURPLE
You lost me at “fill the car up with kerosene “ 😭
Ain't bad done it with diesel & transmission fluid before
this has been done since the 50's, it does work but you have to not be silly. why way back in the 50's+? cuz motor oil used to not have alot of detergents in them.
@Tee Mack 110% correct
after filling up....leave the cap open and throw a lighted match in ! Tadah! no mor engine grit to worry about!
@Tee Mack just commented the same thing lmao glad theres some people here doing the work by spreading the word
go through all that to clean your engine and then put a fram oil filter on it . maybe try a good filter you may not have to do all that lol
@Big Mike no cheap fram filters has paper end caps. Royal purple has metal end caps
Unless you use a proper racing oil filter. All the conventional filters are as good as the other
@@TheFunkymohawk nope... Wix, aka Napa gold filters, are far superior to FRAM. I used to use FRAM and changed every 3k and my oil always looked as dark as the oil in this video. Just went almost 10 with a wix because every time I checked the oil it looked clean! I've always used synthetic oil. I swore off FRAM after one nearly destroyed my phasers...
Do you think the kerosene is actually going to unclog a pick up screen? I was trying to liqui-moly and it did not cure my little oil pressure from a clogged screen
I like the toothbrush ideal, I've seen many oil screens and they are mostly all clogged up. If you are able to reach it with a toothbrush then that's a great idea! Also use a magnetic drain plug to pick up fine pieces of metal.
Good idea!
Magnetic drain plug for modern engines doesn't do much since blocks are made from mostly aluminum these days meaning nothing is magnetic to begin with. When iron blocks were common, yes, using a magnetic drain plug would help.
@Lwnmwrboy5 it's not the blocks that the magnetic drain plugs are used for. It's to collect bearing material which is in every block not matter what it is cast from. And all bearings wear over time not matter how well you take care of the engine.
Won't this break the starter motor ?
+William Poetra Yoga
You do bring up a good question. It is possible that if you crank a starter over and over and over that it would overheat and damage the starter motor. In this particular case I took the starter over a small amount and then give it a break. I have definitely been in that situation where a car will not start and I am cranking it hoping that the car will start soon and in my mind I know that the starter is getting a work out more than it should. In those cases I have put my hand on or near the starter to see if it is overheating. Luckily I have found that the battery will usually be dead before you overheat the starter. What would really be bad for the starter would be to change the battery and keep cranking heavy on the starter. When I was using the starter to crank the engine over in the video are used many small Kranks to move the kerosene through the engine. From experience I did not feel that I was putting an extreme load on the starter. Of course the reason I was using the starter to move the kerosene through the engine was to keep the Pistons moving slow so there would be less wear and tear on the piston rings and the piston walls. I have known people to run the engine with kerosene in the engine without a problem, I'm just being a little more conservative. So the thought I would leave you with is, if you crank The engine with the starter motor make sure that your starter motor does not get hot. If it does get hot let it rest and cool off. I still feel better about giving the starter a bit of a work out rather than running the engine with kerosene instead of oil. I hope I answered your question, please feel free to ask any other questions. Thank you again for your comment.
Will wear it out MUCH faster...if you must...crank for 10-15 seconds continuous...then let it cool for 10-15 min...bumping it like that stresses the contacts and can burn the solenoid contacts
You can doing is motorin diesel for engine
William Poetra Yoga
Starter motor and engine gaskets.
If you take the sparkplugs out, there's less load on the starter. And you can do a piston soak.
Thank you does it cure low oil pressure light?
ATF fluid also works very well. You can substitute one quart of oil with it and drive normally on it untill your next oil change. My auto instructor did it all the time.
Is there a specific ATF to use on a car or just any ATF will do?
USED KEROSENE for 35 years on all my vehicles, Fords, Dodges, all kinds all types and never had problems w shavings. Never had any pinging, clicking, or damage, with long life to the motor. New Filters often have thread shavings on them, check your filters. Its also based on how often you do this and also what kind of oil you use, and running the kerosene thru until it cleans the oil pan. All oils allow for some metal wear, cheap oil will shave your motor more, good synthetic not as much.
Been using 1 bottle of marvel mystery in all my vehicles every other oil change. I'm a betting man that I've owned less vehicles and internally problematic engines than 90% of the people commenting.
Just change your oil on time along with a quality filter.
Also, do not use the kerosene/motor flush trick on an old engine. the sludge inside is sealing off holes that are in your gaskets and other greasy spots, only do this as a last resort! and another note, after flushing your engine, pull the oil pan to clean off potential sludge/junk that might get sucked up in the oil pick-up tube.
false
Everytime he says “grit”, take a shot.
By the way, I think the term for that is either debris or metal shavings.
"Particulate contamination" per aviation maintenance standards.
from the kerosene stripping all the lubrication out
I have been doing this for at least 30 years works every time good knowledge to know
Good way to blow the starter motor
Jonathan Crumley He should've removed the plugs.
seen a guy lockup his motor doing that "sounds good method".
Not really, I rebuilt starters for a while and in my experience it was the long cranking that over heated the starter due to heat cause the persons car would not start, or just old age
Randizle Peregoy i agree. Had put in a new started on a old 4cyl wagon and one day flooded steets got water got on the ignition system since i was missing splash shields and cause the engine to die out and i tried to start the engine over and over again since i was in a bad spot trying to get it started. Held the starter on for about 10 sec each attempt. Eventually draining the battery. Ever since then, the starter acts funny from time to time by not activating when the key is turned.
Gabriel Pla Clean the connections from the battery and from the ignition switch.
I wiped out the rod bearings on my 1954 Hudson using this method and the same thing happened to my friends 1951 Merc.This is an old school method that has been passed down for years.that can do major damage to your engine.BEWARE!!
Yup, it's safer to add 1 or 2 cups of kerosene to the old oil in the engine and run at idle then stop, drain and change the oil filter. I'd never put 100% kerosene in an engine!
@@mmpiforall5913 does this get all the grit out? And I assume it’s much safer if I works right
@@illuminatedzach4206 It gets out a lot of grit, all of it? we'd never know, but I find that the sludge on the inside of the rocker covers is gone, etc. If you have a vintage car, sludge & blow by is common, if you have a 2000s + car and take car of it, there won't much awful grit to get rid of. Don't over-do it, like 100% kerosene or damaged crankshaft seals will occur!! Good luck!
Will the leftover kerosene that still draining down into the oil pan send out the new oil causing more friction?
If your oil. Looks like that at 3000... Wth are u doing to that engine?
krazor8 he poured kerosene in it whet did you think would happen that's what makes his oil look like that You can never get all that stuff out don't care how long you let it drain. Marvel mystery oil works better You can driv around for 20
krazor8 that numbnuts put kerosene in it
Running kerosene in it😛
@@michaelchadwick3497 👍
Accomplished = Nothing.
Oh he accomplished something, he managed to break loose all the deposits from prior lack of maintenance and now is likely to do more damage than otherwise would have been done. Especially with a junk fram filter with the cardboard bypass. If someone tries this on a newer car with variable valve timing they will be taking their vehicle to a shop to have the vvt actuator replaced after the orifice inside gets plugged with sludge. Just leave it alone, the damage is already done.
He took a few months off the life of his starter lol
lol
Right. The inrush current of getting the engine moving heats the windings up more than just keeping it turning for a few seconds.
I would like to add, i have tried this method number of times, instead of cranking the engine 50 times, i used to do it 2-3 times only without letting the engine start. In end, i used to blow pressurized air from inlet and have the remaining Kerosene come out from drain with pressure as that would make sure that non is left inside. This method works and you can feel the difference on your engine running smooth. Many people would disagree with the method, its their own choice but this works well.
Oil filters are for this very purpose. Oil that darkens in colour (UK spelling) is doing its job keeping contaminants in suspension. I agree that some of the 20,000 - 30,000 mile oil change intervals are probably slightly ambitious but there's no need to flush in the way shown here.
This is VERY VERY BAD advice!
Not if you do it the right way.
You are right. Very bad idea and completely unnecessary.
not so much, diesel works well too.
HOWEVER, i don't recommend you turn your car over 50 times in a row as he does. nice way to need a new starter soon.
Looney tunes. And was it me or did it sound like the voice was automated? Like Jeeeeeesus christ pal get some cadence going man!
Google auto oil pump read how they work
Do you do that with your filter on? Or use a dry and new filter to clean the system?
nope, below 300 rpms the pickup cant pick oil (or kerozene) up, to circulate.
Oscar Flyer > That's what I thought. He wasn't turning it over enough. I was told that kerosene is bad on modern engines, never do it.
