Hi, today is Aug 28/ 2023, @ 1:51AM.monday. I've been using Liquid Moli for over a year and a half. Gas and oil treatment. I have a 2004 Nissan Maxima 3.5 V6. It was emitting blue smoke ( burning oil) on start up. Well a friend suggested that I use this treatment to see if it helped. Well, good news! It did and it continues to do so!! No more smoke, the tops of the cylinders are very clean. And the exhaust pipes don't have that black soot. They look new. The cars runs great. I changed out the electronic coils, plugs and installed a new plenum gasket...was leaking a little blow by. Engine is very tight! The stuff is great! By the way? Great video! Liqui- Moli is a great product! All
Wow! Thanks for taking the time to write such detailed feedback. I think so too about Liqui Moly products. I used their engine flush plus and it really did decent work on a sludged up engine. Thanks for the compliments too!
That is a surprisingly thorough testprocedure! Very nice, good pacing and very good method of procedure. The brown residue which is most likely from subpar fuel with excess sulfates etc. won't be burnt away with Liqui Moly. Only with high quality fuel you get a chance. That being said, this residue is neglectable and only carbon buildup is of real concern. Well done!
Great video. Thank you for putting the time and mileage into the project. Liqui Moly is in my opinion the best overall to always use as quality of fuel slowly gets worse. You might want to swap your plugs, valve clean can leave a strange byproduct on them. Fresh plugs will always help everything work the way it should during cleaning.
You know you can also clean plugs? My dad used to do it on his cars when I was a child (loved 'helping' him work on the car at weekends). He had a soft wire bristle brush just for the job, would whip out the plugs, clean off the junk (leaded fuel back then and clearly not as squeaky clean as people like to think) and then check the gap (and reset as needed) with a feeler gauge. Really simple job anyone can do. Seems wasteful to bin plugs just because they look dirty. They last a long time really (my grandad was involved in the manufacture of NGK plugs).
Impressive video and results. Clean pistons improve compression and performance. Its quite difficult to clean them and most products have minimal effect. I use several liquimoly products and i'm also going to try this one.

First option was Performance Improver from Amsoil but was a little expensive and second option remaind from Liqui Moly. I hope to see some results but based on your success I will surely use the Valve cleaner product for the next fill-ups. Thanks for the invested time in searching products that worth buying.
Thanks mate. I'm sure 600km of straight driving will do a lot of cleaning. Getting and keeping the combustion chamber hot with such a cleaner is the perfect recipe for cleaning carbon.

Nice video man i hadnt even thought of moly. Its unfortunately illegal in a bunch of states now but the best bang for buck carbon and all around fule system cleaner ive ever used was RXP Gas Kicker. Best before/after was on a 120k mi 1992 cadillac STS - an aluminum component 4.9L TBI V8. After driving for 200mi I thought the engine died at a stoplight and went to restart the car. It hadnt and my starter was mad at me. Thats just how crazy smooth it was running after blowing puffs of black and gray out the exhaust for the 1st 100mi.
Thanks a lot. Nice. Honestly I think a 200-mile non-stop trip with decent revs will do the trick. Thanks for sharing. Never heard of RXP Gas Kicker. Will have a look.
I use it and it works. But you gotta combine it with a good hard drive. I use it with half a tank and go push the car for 20-30 minutes HARD. Makes all the carbon go away. Also cleans the injectors good. When I say push it hard I mean it, no highway, go to some mountain and go uphill, get some heat into the engine and get 7-8mpg out of it.
@@DIYAutoworksNG it also works for GDI engines, my forester XT never needs Valve cleaning because I push it hard and race it 3x a week. Just pulled the motor to do head gaskets (small leak at 150.000kms, about 500 races) and some seals, the Valves where quite clean.
@@flipd2830 you could also look for some backroads with a lot of cornering... That will keep the speed lower but you should be able to push the engine out of the corners, so it will heat up more than on the highway
this is the best video so far i had watch for fuel cleaner. this is the video that i want to watch, apply and result. other channel that i watch is meh.
@@DIYAutoworksNG I have already used 1 bottle. Can I use 1 more bottle for the next refuel, or is there a recommended range for adding injector cleaner?
I would have used Yamaha's Yamalube Ring Free Plus Fuel additive in the fuel at a shock treatment dosage. This is widely used in the outboard 2 stroke marine industry to remove carbon from valves, combustions chambers, and largely preventing piston rings from sticking. I use this on my outboard engines at every fill-up and it keeps the engine and spark plugs incredibly clean and is safe for both 2 and 4 stroke engines. Ring free treats 10 gallons per ounce, and the "shock treatment" is 5 gallons per ounce is what some people use when they initially buy a used boat that's never been treated with the additive for aggressive cleaning of carbon. See the below video link of this guy using it in an attempt to help his oil consumption. This product is a highly concentrated cleaner, and I would simply mix this with a gallon of gas, pour it into the fuel tank and then fill the gas tank at the station to get the syrup like consistency of the cleaner properly mixed into the fuel. This is not designed to be added to your oil....fuel only. th-cam.com/video/-3Ielu6dJwo/w-d-xo.html
I actually saw this video when it premiered! Thanks for sharing. Apparently what worked most for @FamilyFriendlyDIY aka DIY Dave was the piston soak with B12 chemtool.
@@scottykilmer3920 that because some country already have aditif in fuel it's standard requirement like my country france nobody need to buy lquid moly* that why they say it's fake yes because they already put in fuel! LUL
Yea. It even stopped the oil consumption I was having. I think the Italian tuning plus the cleaner potentially unstuck the oil control rings. I would usually add a quart in 1500 miles or so, but the oil has remained at the top dot through 2000miles of high speed driving.
The big problem with direct injection engines is the accumulation of carbon in the intake valves. In this video the cylinders are cleaner because the gasoline and the product is injected directly into the cylinder and does not pass through the valves. If the valves were shown, they still had carbon deposits. Only solution is a dual injection system like Toyota's
Thanks so much for taking the time to comment and particularly recognising that this 5-min clip took months in the making! I'm running another multi-tank fuel system cleaner experiment! Just waiting to hit 1k miles before my first set of findings!
Hello, nice video documenting your experience. Btw, reading the SDS of this product it seems that it's almost kerosene (no PEA included as you said) but using it regularly and driving with high rpms it seemed to work on your engine. I have to try the same thing as you, but with kerosene.
Thanks for sharing! If you do have before and after footage, I won't mind seeing. Personally can't stomach adding kerosene to the tank for now. Maybe if I know better.
Interesting because PEA is the most common way to reduce carbon build up in an engine. PEA will increase carbon build up on new engines however reduce or remove it on an older engine.
Would be interesting to see what adding it right to the cylinders through the spark plugs would have done. Those tan deposits are super tough to remove with a wire brush even. My old carborated harley pistons are cleaner than that after about the same km..... the wonders of 'modern' technology lol
Yep! Slow process it is. Probably why it comes in that can of 12. Lol. That said, I'm yet to see something that gives spick and span results in one treatment!
Cool. How do you know it was not the spirited driving alone though? Proof would be that the double treatment did not make much difference but rather the continuous spirited driving?? 🤷♂️
Agree, I have done borescope comparisons on my GDI engine using premium fuel. In as little as 15km of high rpm and multiple WOT runs significantly reduces carbon. th-cam.com/video/Zr6m5WGjpg4/w-d-xo.html
@@DIYAutoworksNG you better ask the company first 😎 Engine cleaner to put into your Oil than 15 min on 1,500 rpm before oil change… 99% Diesel 🤷♂️ You just pay a lot more 🤪😂😂
Good question! Both definitely had an effect. I'm yet to test removing significant carbon build up with just a Italian tune up. Will look into this whenever next I have a planned long trip!
Most interesting for me - how about try "clean" pistons only with long run on high rev?🌚 My thoughts: higher revs - higher temperature - more "vibration" - all provides to self-cleaning 🌚 Do we really need those additives?🌚
Looks like it does a good job. I wonder how much of a difference it really make by cleaning the carbon build up off the pistons? Would have been good the do compression numbers before and after.
Yea. Doing compression would have been another good addition! However, engine was pinging before this. Totally gone afterwards. Also gained 2 - 3 mpg and cut my oil loss by more than half telling me that it did free up oil control rings.
Excelente video, estoy interesado en realizar la prueba en mi vehículo. Quisiera consultar que clase de combustible es la que cargaste que dice combustible limpia en 5to tratamiento?
I used to clean valves all the time the hard carbon would have to be steel brushed off the valve it took alot of work I would say the best thing is to take preventative measures before they have that much build up lol
Good method of testing. Pity you did not perform an engine compression test before and after since removing carbon buildup should remove carbon buildup around your oil scraping rings on the pistons thus improving compression and reduce oil consumption if they are not worn too much. Did you note any change in oil consumption afterthe cleanup?
Great point there. That would have made the puzzle complete! Will consider for future efforts. But it definitely improved compression because oil use dropped. I have a video on the benefits I gained after doing this treatment; decrease in oil consumption included! th-cam.com/video/7acdMb10Kbw/w-d-xo.htmlsi=2xc_e54d_-lEGGoW
Your efforts are much appreciated. Help us to know What is the difference between liqui moly valve cleaner and diesel purge? Combustion for all like valve, piston and spray nozzle happens same time. So cleaning point starts from Diesel spray nozzle, valves then to piston. Would all these also cleaned. A big thanks in advance
Piston carbon build up isn't an issue on modern engines using modern fuel. Considering that Earth Dreams engines are direct injection, your worry should be carbon build up on the back of the intake valves. That's what Liqui Moly valve cleaner is meant for. Cleaning the fairly thin layer of carbon on the piston head is just burning money.
Yeah, no mention of the car getting better MPGs or feeling like it has more power or idling better. Not to mention once Liqui Moly is out of your system the carbon is going to rapidly build right back up again.
50 50 mix of distilled water and windshield washer fluid will clean it much better. It does it slower. If engine spends time at idle you can have more buildup like in cold weather.
Thanks for sharing! Won't windshield washer fluid have one of those catalyst poisons? Your last sentence is why I get a lot of build up. Some usual traffic in my regular routes.
No it won't. Think of a blown head gasket. The cylinder that injest the coolant is perfectly clean. Piston and valves. The water turns to vapor and the washer fluid helps it turn to vapor faster. It does not take much. Inject it behind throttle body. Use a vacuum switch so it come on under load or when acceleration. Most buildup occurs from PVC positive crankcase ventilation.
I have a diesel car but always add the 'supreme' diesel rather than standard as it supposedely has more detergent in it. Of course no way for me to test that claim but I don't get DPF problems like so many other people. Sure the outlay is a bit higher but I'm not paying a garage to clear error codes or try and flush my DPF so probably balances out. I used to use a particular additive (won't name them) but after calling their helpline after I split some on myself the guy let slip it's basically kerosene... which would have been about 10 times cheaper to buy than the additive was.
I wana know what the valves look like tbh, I saw how dirty it was under my valve covers and well. it wasnt pretty so i would love to clean it without opening the covers and all that
I know that is the head gasket is leaking coolant in the cylinder , that piston is clean. Wouldn't be interesting to actually have while running the engine, from time to time to inject a mist of water? That would be a nice experiment
Good question. Yes there is. Depends on how thick the layer is. Increased carbon will reduce the volume of the combustion chamber and thereby affect compression ratio. An out of spec compression ratio will lead to spark knock or pinging. I was having this before starting the cleaning process. It was gone when I was done. Remember, the combustion chamber is actually the little space with the piston at the top of its stroke (top dead center), so it's much smaller in volume compared to what I show in the video.
It sounds like redlining your car every so often is the best thing you can do. Great video but not sure how much the liqui moly did compared to the high revving
I hope you will answer this question. After all of the Chrome-Moly you put in your tank. Did you look at the valves to see before and after the use of this product? Tour videos are very useful and I thank you sincerely. I'm driving an 02 Accord LX 2.3L with 5 Speed Manual Transmission. I've owned this Awesome Accord since I bought it Brand New.
Sure pleased to answer! No need looking inspecting the intake valves since the engine is GDI. That car is sure going to be so difficult for you to let go of. I let go of a 2003 Accord I had for 13 years. Almost cried when the guy drove off🤣
it si a valve cleaner, and your video is about the impact in the combustion engine. You car is fuel injection (not direct injection), the results will be more appreciated in the intake valves.
Thanks for your compliment! I tested it on soaking carboned up spark plugs and noticed that its not good as a soaking agent. Did nothing in terms of softening the deposits. That just tells me it needs heat to activate.
Very nice video, only my question is does the car's tank have to be completely empty or only half full.....and I also wanted to ask you, do I have to refill the Liquid Moli with every tank?
@@DIYAutoworksNG Thank you for your answer but you didn't answer my second question, which is that I have to add these additives every time I fill up the tank
Hello that's what I meant by consistent use. Not practical to use every single time you fill up, but good to use back-to-back for some fill ups. Also, if you use premium gas, you likely won't need this.
Hi, nice video! I have one question, all the carbon removed stuck in the catalytic? Or it will be desentigrated and no harmful the catalytic? Thank you!
Great point! From the previous videos I've done investigating this, the risk is minimal. Search for the videos I did on "will CRC clog your catalytic converter", and the BG44K Platinum video. I think the only place where there would be issues is if the catalytic converter was maybe partially clogged already. It could also be that I haven't tested products enough to see if its a problem!
What do you think? 🤔 Willing to go several fill ups in other to get clean pistons? I guess significant buildup will require multiple treatments.

From a previous video I did, it will burn off and not get trapped in the CAT.
It will break down your engine due too a thick layers of carbon over piston@@davidkrocks

be nice to pair this with an oil catch can, and of course an oil change not too long after application. great vid!
Right on the money! I have an oil catch can already installed. Did so early this year. Has significantly cut deposits reforming since installed.
an oil catch can on a Honda GDI engine is pointless it will have minimum effect so its not needed.
Nice video man i hadnt even thought of moly. Its unfortunately illegal in a bunch of states now but the best bang for buck carbon and all around fule system cleaner ive ever used was RXP Gas Kicker. Best before/after was on a 120k mi 1992 cadillac STS - an aluminum component 4.9L TBI V8. After driving for 200mi I thought the engine died at a stoplight and went to restart the car. It hadnt and my starter was mad at me. Thats just how crazy smooth it was running after blowing puffs of black and gray out the exhaust for the 1st 100mi.
Thanks a lot. Nice. Honestly I think a 200-mile non-stop trip with decent revs will do the trick. Thanks for sharing. Never heard of RXP Gas Kicker. Will have a look.
I use it and it works. But you gotta combine it with a good hard drive. I use it with half a tank and go push the car for 20-30 minutes HARD. Makes all the carbon go away. Also cleans the injectors good.
When I say push it hard I mean it, no highway, go to some mountain and go uphill, get some heat into the engine and get 7-8mpg out of it.
Thanks for sharing. Interesting take on pushing hard. That will certainly turn up the heat🔥
@@DIYAutoworksNG it also works for GDI engines, my forester XT never needs Valve cleaning because I push it hard and race it 3x a week. Just pulled the motor to do head gaskets (small leak at 150.000kms, about 500 races) and some seals, the Valves where quite clean.
Wow! Thanks for this insight. Will try this out.
Hmmm,....going to look for a mountain in south florida to try this out.....lol
@@flipd2830 you could also look for some backroads with a lot of cornering... That will keep the speed lower but you should be able to push the engine out of the corners, so it will heat up more than on the highway
this is the best video so far i had watch for fuel cleaner. this is the video that i want to watch, apply and result. other channel that i watch is meh.
Glad you found it helpful!!!!
@@DIYAutoworksNG I have already used 1 bottle. Can I use 1 more bottle for the next refuel, or is there a recommended range for adding injector cleaner?
That's exactly how I did it. Used it consistently with every fill up.
It works great. It also is a great presoak on pistons and heads if you're cleaning up carbon. Overnight and it flakes off and cleans right up.
Good to know. Never tried using it as a a presoak.
I would have used Yamaha's Yamalube Ring Free Plus Fuel additive in the fuel at a shock treatment dosage. This is widely used in the outboard 2 stroke marine industry to remove carbon from valves, combustions chambers, and largely preventing piston rings from sticking. I use this on my outboard engines at every fill-up and it keeps the engine and spark plugs incredibly clean and is safe for both 2 and 4 stroke engines. Ring free treats 10 gallons per ounce, and the "shock treatment" is 5 gallons per ounce is what some people use when they initially buy a used boat that's never been treated with the additive for aggressive cleaning of carbon. See the below video link of this guy using it in an attempt to help his oil consumption. This product is a highly concentrated cleaner, and I would simply mix this with a gallon of gas, pour it into the fuel tank and then fill the gas tank at the station to get the syrup like consistency of the cleaner properly mixed into the fuel. This is not designed to be added to your oil....fuel only.

I actually saw this video when it premiered! Thanks for sharing. Apparently what worked most for @FamilyFriendlyDIY aka DIY Dave was the piston soak with B12 chemtool.
I love using all of Liqui Moly’s products!
They are becoming my go-to too!
This was an excellent video. I especially liked you explaining on opening the car up on those longer trips. Well done!!
Glad you enjoyed it! Thanks!
never had these problems. I only used ROZ 98 and better fuel. the pistons was so clean and I cleary saw the QR codes from the factory ^^
Nice. Unfortunately we don't have those higher octane fuels in my setting.
exactly, if you use premium fuel, you dont need any of these additives.
@@scottykilmer3920 that because some country already have aditif in fuel it's standard requirement like my country france nobody need to buy lquid moly* that why they say it's fake yes because they already put in fuel! LUL
One of the best before and after videos!! Excellent job, you made me go try this.
Thanks!
Clearly a cleaning method for the patient minded.
Yea. Well, if you have significant build up like I did, you'll have to be patient except you want to pull the head or do a piston soak.
@@DIYAutoworksNG Non-invasive is good.
Yea. It even stopped the oil consumption I was having. I think the Italian tuning plus the cleaner potentially unstuck the oil control rings. I would usually add a quart in 1500 miles or so, but the oil has remained at the top dot through 2000miles of high speed driving.
@@DIYAutoworksNG It's good to have collateral benefits instead of collateral damages. 😄
@@DIYAutoworksNGlso Is this Product less effective if i dont floor it ???? Meaning it wont clean carbon in city driving
I appreciate the way you did this video, meat and fufu, no need for anything else.
🤣😂🤣 @ meat and fufu!
Brilliantly done video! Always thought this sort of liquid was snake oil but after watching your video I'm going to give it a try, thanks
Thanks
Hello @andrejedidaniels, did you give it a try? Any feedback after one year? Thank you.
The big problem with direct injection engines is the accumulation of carbon in the intake valves. In this video the cylinders are cleaner because the gasoline and the product is injected directly into the cylinder and does not pass through the valves. If the valves were shown, they still had carbon deposits. Only solution is a dual injection system like Toyota's
💯 Agree! I don't know why other manufacturers have not adopted dual injection.
They want service they dont f about us
So you are telling me the product is going to be less effective at cleaning carbon build on pistons on a car with port injection only????
Nope. It's should clean as well!
This is awesome, thank you for sharing! and investing and taking the time to demonstrate this.
Thanks so much for taking the time to comment and particularly recognising that this 5-min clip took months in the making!
I'm running another multi-tank fuel system cleaner experiment! Just waiting to hit 1k miles before my first set of findings!
Hello, nice video documenting your experience. Btw, reading the SDS of this product it seems that it's almost kerosene (no PEA included as you said) but using it regularly and driving with high rpms it seemed to work on your engine. I have to try the same thing as you, but with kerosene.
Thanks for sharing! If you do have before and after footage, I won't mind seeing. Personally can't stomach adding kerosene to the tank for now. Maybe if I know better.
Interesting because PEA is the most common way to reduce carbon build up in an engine. PEA will increase carbon build up on new engines however reduce or remove it on an older engine.
@brarautorepairs How does PEA increase build up in newer engines?
I tested several. The best one to clean combustion chambers was Italian Tuneups on pure E85...
Thanks for sharing your process! Alcohol does burn cleaner.
I would love another test with a MPFI car, as these being an older techology found in older cars, deposits MAY be even more substantial/
Great Vid .
Thanks mate. On the contrary, GDI would have more buildup all things being equal.
Good video. I imagine those long 100 mile Italian tuning sessions are where the product worked best.
Exactly!
Damn nice video man. I think a lot of people are scared to tamper with their vehicles and are uninformed. Keep up the good educational videos!!!
This means a lot. Thank you for taking time to comment!
Best video and explanation for the product. Liqui moly should hire you bro 👍🏽
🤣 Thanks for watching!
Would be interesting to see what adding it right to the cylinders through the spark plugs would have done. Those tan deposits are super tough to remove with a wire brush even.
My old carborated harley pistons are cleaner than that after about the same km..... the wonders of 'modern' technology lol
You should see today's video! Not soaking but interesting all the same.
Use the Liqui-Moli oil treatment! It does work.
I use a can of it at every oil change.
Thanks. Looks like a slow process which is probably good. This product is available in a case of 12!
Yep! Slow process it is. Probably why it comes in that can of 12. Lol.
That said, I'm yet to see something that gives spick and span results in one treatment!
To think that I just started researching about Ceratec and I saw your notification 😂
😁 Haven't used ceratec before, but I've heard good things about it.
Thank you for informative content. Only thing i was hoping for but didnt get was why i shouldn't do this
Well... If you have access to top tier gas, then I guess you wouldn't need this because the fuel should have additives to reduce build up.
great results! could you also try hot shots secret gasoline extereme?
Thanks, mate! I'll look into getting the hot shots. Haven't found it locally. Being HAZMAT, will be challenging to ship internationally.
Cool. How do you know it was not the spirited driving alone though? Proof would be that the double treatment did not make much difference but rather the continuous spirited driving?? 🤷♂️
Good point. Recently did a separate run without additives. Videos should be coming soon.
I would like to see the same test but without liqui moly... just keep those revs up and I bet you could get the same amount of cleaning.
Challenge accepted!
Agree
Agree, I have done borescope comparisons on my GDI engine using premium fuel. In as little as 15km of high rpm and multiple WOT runs significantly reduces carbon. th-cam.com/video/Zr6m5WGjpg4/w-d-xo.html
Hey, thanks for sharing. Seems like the video is offline. Followed the link but it pulled a blank screen.
When???@@DIYAutoworksNG
I got a Veloster 1.6 GDi, gonna try this method.
It’s pretty much the same as breakfluid…
Remember Valves are in need of their ‚crusted surface‘.
It’s always good to know how to do the needs.
This is not true. Unrelated to brake fluid.
@@DIYAutoworksNG you better ask the company first 😎
Engine cleaner to put into your Oil than 15 min on 1,500 rpm before oil change… 99% Diesel 🤷♂️
You just pay a lot more 🤪😂😂
Excellent video, perfect amount of info and length. Subbed
Awesome, thank you!
Is every comment written by a bot? Good lord.
Yeah these all fakes bot I only trust liqui moly injector cleaner since it work for me
Liquimoly is the only brand I trust for my cars maintenance try some today by going to your local automotive shop
Sure feels like it is lmfao
Think so lol
this is a great comment! my mileage went up 6 mpg after reading it! I'll be re-reading this comment every 500 miles from now on!
Excellent video! I wonder which had more effect on carbon removal. Driving hard for extended periods of time aka “Italian tune up” or the additive.
Good question! Both definitely had an effect. I'm yet to test removing significant carbon build up with just a Italian tune up. Will look into this whenever next I have a planned long trip!
I have subscribed to your channel. Very well presented and informative
Thank you!
Most interesting for me - how about try "clean" pistons only with long run on high rev?🌚 My thoughts: higher revs - higher temperature - more "vibration" - all provides to self-cleaning 🌚
Do we really need those additives?🌚
Did that already 😁. Here th-cam.com/video/S12ioOeiRWk/w-d-xo.html
80k miles ..what are you burning. Coal.
I use this product every second tank fill up. Reduced fuel consumption.
Ty , it was exacly for what i´m looking for , continue doing this type of reviwes to thos products
Thanks for taking the time to leave a comment. Means a lot. Yes, will continue. I have quite a bit of fuel system cleaner videos on the channel.
Looks like it does a good job. I wonder how much of a difference it really make by cleaning the carbon build up off the pistons? Would have been good the do compression numbers before and after.
Yea. Doing compression would have been another good addition! However, engine was pinging before this. Totally gone afterwards. Also gained 2 - 3 mpg and cut my oil loss by more than half telling me that it did free up oil control rings.
Excelente video, estoy interesado en realizar la prueba en mi vehículo. Quisiera consultar que clase de combustible es la que cargaste que dice combustible limpia en 5to tratamiento?
Thanks for the compliment. No difference in the 5th tank. I used exactly the same fuel I've been adding.
lol. One tank of fuel lasts me one to two months. The shot of four bottles for four fillings caught me off guard.
I used to clean valves all the time the hard carbon would have to be steel brushed off the valve it took alot of work I would say the best thing is to take preventative measures before they have that much build up lol
100% right you are!
Like what?
Good method of testing. Pity you did not perform an engine compression test before and after since removing carbon buildup should remove carbon buildup around your oil scraping rings on the pistons thus improving compression and reduce oil consumption if they are not worn too much. Did you note any change in oil consumption afterthe cleanup?
Great point there. That would have made the puzzle complete! Will consider for future efforts. But it definitely improved compression because oil use dropped. I have a video on the benefits I gained after doing this treatment; decrease in oil consumption included! th-cam.com/video/7acdMb10Kbw/w-d-xo.htmlsi=2xc_e54d_-lEGGoW
Your efforts are much appreciated.
Help us to know What is the difference between liqui moly valve cleaner and diesel purge?
Combustion for all like valve, piston and spray nozzle happens same time. So cleaning point starts from Diesel spray nozzle, valves then to piston. Would all these also cleaned.
A big thanks in advance
Piston carbon build up isn't an issue on modern engines using modern fuel. Considering that Earth Dreams engines are direct injection, your worry should be carbon build up on the back of the intake valves. That's what Liqui Moly valve cleaner is meant for. Cleaning the fairly thin layer of carbon on the piston head is just burning money.
Yeah, no mention of the car getting better MPGs or feeling like it has more power or idling better.
Not to mention once Liqui Moly is out of your system the carbon is going to rapidly build right back up again.
I addressed the reasons and gains from doing this in this video th-cam.com/video/7acdMb10Kbw/w-d-xo.htmlsi=o9OWrcEhNaSUybCI
50 50 mix of distilled water and windshield washer fluid will clean it much better. It does it slower. If engine spends time at idle you can have more buildup like in cold weather.
Thanks for sharing!
Won't windshield washer fluid have one of those catalyst poisons? Your last sentence is why I get a lot of build up. Some usual traffic in my regular routes.
No it won't. Think of a blown head gasket. The cylinder that injest the coolant is perfectly clean. Piston and valves. The water turns to vapor and the washer fluid helps it turn to vapor faster. It does not take much. Inject it behind throttle body. Use a vacuum switch so it come on under load or when acceleration. Most buildup occurs from PVC positive crankcase ventilation.
I have a diesel car but always add the 'supreme' diesel rather than standard as it supposedely has more detergent in it. Of course no way for me to test that claim but I don't get DPF problems like so many other people. Sure the outlay is a bit higher but I'm not paying a garage to clear error codes or try and flush my DPF so probably balances out.
I used to use a particular additive (won't name them) but after calling their helpline after I split some on myself the guy let slip it's basically kerosene... which would have been about 10 times cheaper to buy than the additive was.
Yea. I agree with higher quality fuels. The extra detergents does help engines run cleaner.
I wana know what the valves look like tbh, I saw how dirty it was under my valve covers and well. it wasnt pretty so i would love to clean it without opening the covers and all that
I got you. I've a couple of valve cleaning videos using CRC intake valve cleaner and Liqui Moly Throttle valve cleaner
No annoying hands and music, ty.
I hate those too. Lol
I know that is the head gasket is leaking coolant in the cylinder , that piston is clean. Wouldn't be interesting to actually have while running the engine, from time to time to inject a mist of water? That would be a nice experiment
Yea, but I shy away from the water injection treatment because some of it will mix with the oil
Best video review ever i like the camera down the cylinder to see before n after 👌👏👏👏
Thanks for the compliment! I do a lot of these fuel system cleaner videos, and have some more in the works!
Genial video, gracias!
Has probado el limpiador de inyectores de Liqui Moly?
Thanks! I have it in stock, but haven't used.
Great video! Is there any evidence that proves that a layer of carbon on the tops of pistons has any detrimental effect on engine performance?
Good question. Yes there is. Depends on how thick the layer is. Increased carbon will reduce the volume of the combustion chamber and thereby affect compression ratio. An out of spec compression ratio will lead to spark knock or pinging. I was having this before starting the cleaning process. It was gone when I was done.
Remember, the combustion chamber is actually the little space with the piston at the top of its stroke (top dead center), so it's much smaller in volume compared to what I show in the video.
It sounds like redlining your car every so often is the best thing you can do. Great video but not sure how much the liqui moly did compared to the high revving
Very valid point. Another experiment will tell. I agree that regular high revs are good for cleaning carbon.
High rpm’s won’t do anything to remove carbon. The liquid moly did the job.
I hope you will answer this question. After all of the Chrome-Moly you put in your tank. Did you look at the valves to see before and after the use of this product?
Tour videos are very useful and I thank you sincerely. I'm driving an 02 Accord LX 2.3L with 5 Speed Manual Transmission. I've owned this Awesome Accord since I bought it Brand New.
Sure pleased to answer!
No need looking inspecting the intake valves since the engine is GDI. That car is sure going to be so difficult for you to let go of. I let go of a 2003 Accord I had for 13 years. Almost cried when the guy drove off🤣
My man emptied 4 tanks in a 5 minutes video. Impressive
🤣 This was more than 6weeks of footage in 5mins. Lol
Should be pretty easy for me in my v8 petrol 100 series Landcruiser 😂. Just speed up and the tanks empty!
@@DIYAutoworksNG thanks for your efforts
it si a valve cleaner, and your video is about the impact in the combustion engine. You car is fuel injection (not direct injection), the results will be more appreciated in the intake valves.
Yea, was running out of options and needed to try this. The better product will have been DI Jectron.
Straight to the point. Well done and thank you.
You're welcome!
I never knew one can wouldn't be enough.😮
Great video!
Thanks mate!
Thanks for the great video, well done! Did you consider pouring the additive into the combustion chambers and letting it soak over night?
Thanks for your compliment!
I tested it on soaking carboned up spark plugs and noticed that its not good as a soaking agent. Did nothing in terms of softening the deposits. That just tells me it needs heat to activate.
try Redline Complete Fuel System Cleaner , worked for me very well with one treatment
I have my eyes set on this!
Thank you for this video. Do you think that it cleans piston ring as well?
Yes. I did a follow up video on the benefits I gained after this procedure. Oil consumption went down significantly.
@@DIYAutoworksNG Thank you for your answer.
Great video! But what`s the point of this experiment? Did this prolong your engine life? Improve your car`s performance?
Thanks mate.
Stopped the pinging that I was having due to carbon build up, also increased fuel economy by 2-3 mpg.
Very nice video, only my question is does the car's tank have to be completely empty or only half full.....and I also wanted to ask you, do I have to refill the Liquid Moli with every tank?
Thanks for the compliment. Tank doesn't have to be completely empty for this product. I found that consistent use is what brings the result.
@@DIYAutoworksNG Thank you for your answer but you didn't answer my second question, which is that I have to add these additives every time I fill up the tank
Hello that's what I meant by consistent use. Not practical to use every single time you fill up, but good to use back-to-back for some fill ups. Also, if you use premium gas, you likely won't need this.
Hi, nice video!
I have one question, all the carbon removed stuck in the catalytic? Or it will be desentigrated and no harmful the catalytic?
Thank you!
Great point! From the previous videos I've done investigating this, the risk is minimal. Search for the videos I did on "will CRC clog your catalytic converter", and the BG44K Platinum video.
I think the only place where there would be issues is if the catalytic converter was maybe partially clogged already.
It could also be that I haven't tested products enough to see if its a problem!
@@DIYAutoworksNG Thank you man! I'll search the videos.
You have subscribe from me for not pushing in deep video to 20 minutes. Good job!
Thanks mate. 😅 When looking for videos, I also like brevity, though some subjects can't but be longer.
I totaly agree and wish more youtubers be like you. Keep doing good job, you are gem!@@DIYAutoworksNG
Many thanks!
Liqui Moly should literally pay you some commission for every of their valve cleaner sold. Im going buy 6 cans of liqui moly valve cleaner 😂❤.
Lol. Video totally not sponsored.
@DIYAutoworksNG I meant.. you have done such a great experiment that liqui Moly themselves haven't showcased the full ability of this product.
