- What happens if you put gasoline in a diesel car? What if I put gas in my diesel truck? What if you put diesel fuel in a gas car? We'll walk through all of the components, the fuel tank, in-tank pump, fuel filter, electronic pump, high pressure pump, fuel rail, and fuel injectors to talk about what damage might occur, and what you can expect the dealer to replace.

This is all ridiculous. I've been in this spot before. You just drain the system, replace the filter, refill with diesel, and start her up. Replacing the entire fuel system for eight grand because one part might fail in ten thousand miles is something only the mechanic who's charging for the work would think reasonable.
I'll second that. Just a money spinner. Depends how long you drove it though. Then you deserve the Darwin award.
Me, I've filled a couple of times with diesel. Just pump her out, Blow the lines out. Refill WHOLE tank with Diesel. Way you go. Also have put a liter of petrol/tank every six month as injector cleaner.
The manufacturer mandates to the dealership mechanics what needs to be repaired for this particular problem. He's not just a shop mechanic, he's a dealer mechanic. If he doesn't replace those parts and one of them fails down the road, it falls on VW to explain and fix it, not this guy or his shop. We're also talking about modern, precision engineered diesel engines, not the rusted out 1970 chevy that spews a plume of black smoke every time the gas pedal is touched.
The reason people use the dealer mechanic instead of just a regular shop is because they don't cut corners. Yes, they may do more than is necessary sometimes, but it's always in the name of longevity of the vehicle. Personally, if I were in this situation, I'd prefer to spend more to know beyond a shadow of a doubt that my car isn't going to break down in 2 months with my wife driving alone on a backwoods highway 80 miles from the nearest mechanic.
Feel free to fix your vehicles however you see fit, but I don't think it's close to ridiculous for other people to be willing to pay extra for the piece of mind, and I don't think it's ridiculous for VW to require this extensive repair for this situation where they would be liable.
I have a 2002 Jetta Diesel since new with 475k on it now. Always been mixing 50 to 1 in the summer and 25 to one in the winter. I get 1400+ km on the highway and anywhere from 1000km to 1200km in the city. Also been using Amsoil since day one. Oh and everything is original on the engine except the normal maintenance requirements and twice I had to replace the alternator clutch pulley.
+DJ Harrison LOL. Stealership techs are more inept than a reputable indie shop. The tech are just there for a paycheck while indie shops actually care about their business.
I put fuel into my 2013 common rail work truck when its was brand new, and drove it for about 30 kms. All we did to fix the problem was drain the fuel out of the tank and change the filter.
That same truck has done 140,000 kms since then with no issues whatsoever.
$8000 repair, pfft! That's criminal...
I'm suprise he didn't recommend changing the A/C unit and the tires
And the cupholders
And the blinker fluid!
Let's just replace the entire engine while we're at it.
That's worth most cars on craigslist, utterly insane!!!
I accidentally put coal in my 737 airliner once.
Same, I won’t make that mistake twice
Just switch it off and on again
Did it smoke any?
Me too, I just flushed it out with gasoline then flushed it again with diesel. It ran kinda rough for a while but I walked it off so to speak.
I've been a mechanic for almost 40 years (aviation, automotive, heavy equipment) and have seen my fair share of this kind of thing. Replacing fuel lines and cleaning things out with BrakeClean and compressed air to eliminate every drop of gas is really unnecessary. Claiming the fuel rail is a sealed component that you can't service or see inside is also quite incorrect. The one you show: all you have to do is removed the fuel sensors and any metal trapped in there could easily be removed with compressed air. As far as the pumps and injectors go, unless the vehicle was run on straight gas for quite some time (which would be difficult because the head gasket won't last very long), they're more than likely going to be fine. If there was any pump damage, you'll find evidence of it in the fuel rail.
You can also dump the gas/diesel mix with your waste oil. (And where do you live that it costs $25/gal to dump that stuff?)
Thanks for coming by man.
I hope I know what the hell I am talking about. Lol at least I think I nailed "Hello everyone, AND welcome". Lol
Always a pleasure Charles.

2- Don't put gasoline in a diesel engine
3- If you're thinking of not doing number 2 (that is to not not put gasoline in a diesel engine) then drive an old diesel engined car

Why not replace the whole engine while you're at it. Better yet, replace the entire car...

Do you know how much engines cost for better cars? it's way cheaper buying new parts instead of a new engine.
That always happened to us
There's a good song about that. "One piece at a time" I think it's called...
14x25=3000
I think we discovered why so many people get over charged getting work done on their car. mechanics can't math
I make math mistakes all the time, everyone does regardless of background. Don't read into it too heavily, we have computers to do the heavy lifting these days.
+Engineering Explained I was just making fun of a social issue. people get massively overcharged all the time.
+Jack Truitt Well I just wanted to make it clear that Charles is a very honest and knowledgable fellow, though I think his channel speaks that quite clearly.
+Engineering Explained I'll be sure to go check it out, though I have no doubts about his knowledge or skills
I dont know what kind of math you were teached but 14x25 is 350
7:45 that awkward moment when you realize you overcharged a customer...
actually, that awkward moment when you realize you the customer has a brain and knows the math doesn't add up
It worries me that this gentleman is out there suggesting this kind of work for this problem. Other mechanics will charge $100 and send you on your way. This fellow charges $8,000 just in case things were damaged by exposure to gas. The thought process he goes through is frightening. "This could be impacted, new assembly. This might be touched, new assembly. This could have a thing in it, new assembly."
It's outrageous.
+WoodysGamertag dude its crazyy seeing you here
+WoodysGamertag woodys not a car guy
this guy works for a dealer and OEM have procedures(bulitens) what to do when a diesel engine is run with gasoline . the metal contamination I also seen it in BMW our repair for this usually run around 15k. if the engine is not run we jusy drain the tank
+WoodysGamertag Crazy seeing you here Woody! I would have to disagree. Any common rail diesel will need to have all these parts gone through if you run gas through it long enough. It is under extremely high pressure, and under very high tolerances. Yes with older diesels you just flush the system and make sure it's primed with diesel and be on your way, but it's not like that with the newer systems.
none of what he said to replace was for exposure to gas, except for the things that would be ruined by gas.
Mechanic: "I'm really bad at math." Customer: "I hope you didn't have any input into figuring out my bill."
Service advisor who gets paid on commission: "don't worry, he didn't"
The thought process a mechanic goes through to give a person an estimate is very...... disturbing
How is that?
+HumbleMechanic It did seem a bit suspect when it was like 4000 + 1200 + 350 = 8000... uhm.
+HumbleMechanic I'm not hating though, people have got to get paid and your industry does benefit from from people generally having no clue about cars.
+Ben Melluish remember that this is a VW mandated repair. VW was paying for the repair.
If a dealer made a repair not inline with the strict instructions from VW, and the customer has an issue, the dealer becomes responsible for fixing it.
+Ben Melluish hahaha however I will take full responsibility for my bad math. That's Jason's department. ;)
I worked almost 20yrs on medium + heavy duty trucks and all kinds of equipment. Unless it was ran under a load and overheated badly, we drained all the tanks and lines, blew out the system, fresh filters and fill with diesel with no problems. I only saw a handful of damaged engines because of gasoline ingestion, usually new engines that hadn't broken in and none catastrophic. I think your repair procedures are quite a bit overkill. Replacing good parts because they "might" fail in the future??? is bs, parts are either damaged or not, even the rubber lines shouldn't be bad. I usually enjoy your videos but this one bombed.
I have to agree with you Jim about over kill about putting gas in a diesel motor mostly with older diesel motors are built to handle way more than a modern diesel motor will do because I have a old VW diesel motor and I have put in quarter of a gallon of gas in my diesel often in the winter time for faster starts and less gel up with diesel fuel on summer grade fuel and better performance. Been doing it to my older diesel for many years now and no show of any damages to my diesel motor at all,
the russians mix diesel with gasoline up to 1:1 otherwise it would freeze or flake out and clog a filter or whatever... their heavy duty stone age engines handle it quite well as far as i know
Near the end of the video they said old diesel systems where less harmed than newer ones. And that they fixed them the way you describe. Could it be that you where working with those older systems?
Hi my good peoples, I have BMW X3 diesel,just brought into garage after the owner mistakenly put petrol second time again, even we clean the tank and replaced diesel pump just run few miles now doesn't want to start.should I replace pressure pump, rail pressure and diesel injectors?
Hi, could you possibly help me. I need I asap. We bought a skoolie. The guy dropped it off to us and everything seemed great. Until we tried to start it after he left and we realized he left us on empty and it wouldn't start. We went and got a big 20 gallon fuel can to fill it up, but then read that we would need to prime it, or bleed the engine first. It is a flatnose FE dt466. We are not mechanically inclined at all! If anyone could walk us through these steps I would be forever in your debt. It's just me and my 22 year old daughter, yeah we are in way over our heads, but I can't get it from my house to the mechanic for real knowledge and help with this first. Ugh, help🤯😬
Different times, back in the days we used to put 10% gas on diesel cars @ winter here in nordic countries. Can't do that with modern diesel engines.
+Rentta I still hear of that here. Especially when the temperature is around 0F
+70chevelle8 cheap anti-gel
+Rentta I still do it, I have a 2004 Toyota.
Around 5% but only if temperature goes below -10°C in the night.
+KevinTheFirefighter I ran my VW van on a mixture of waste veg oil and 20% petrol for 6 years with no problems, Don't try it on a common rail but the old Bosch V series pumps are all but indestructible
+Rentta
Today we regularly mix up to ~10% Kerosene into our diesel for cold weather use.
No gel, no hard starts, no fuel system or engine damage.
Kerosene is a fuel oil and has lubricating properties, gasoline is technically a solvent with virtually no lubricating properties.
Over kill for sure. Seen this situation many times. If gasoline was put into the tank but the engine not started, then just drain the tank the best you can and refill with diesel. If the engine was started and run for only a short time, again, drain the tank, replace with diesel then turn on the key and let the fuel pump run for awhile. The gas will mix with the diesel and be diluted.
In 40 years I have never seen a bit of gas hurt a diesel engine. If something does fail down the road, replace it then. Chances are the gas had nothing or little to do with it. I know of one case where a fellow put about 5 gallons of gas into his tank before realizing his mistake. Being too cheap to drain the tank, he just topped it up with diesel and ran it through. Drove that truck for another 10 years before he sold it. It ran like a charm.
Jesus just drain the tank and refill it with diesel, if the parts fail then change them.
Exactly!
+MrGuvEuroman well problem is, if you get those metal particles from the high pressure pump into your injector, and it starts to leak fuel into the cylinder, your going to wash away the oil in the cylinder lubricating the pistons. sooo your going to have a engine failure aswell... so rather change fuel filter, high pressure pump, rail and injectors, before having to replace the hole engine later on.. the higher the pressure in fuel system, the more likely that this will happen... its still a low chance overall, but yea.. "be safe, spent a lot" right?
i have. I just may not be able to express myself like i wanted to. (english is my secondary language).
I mean like, you have put gas into your diesel car, and you stopped. Now the tow truck brought you to a shop, and they flushed the system. Now, after 50k miles (or whatever) there could still be metal particles in the system, potentially damaging the injectors, which may start leaking. (its a lot of if and may... i know).
Now the problem is, where i live, you have to give warranty on your work, no matter what you did, for 1 year. My buddy is working in a car shop and they had exactly that problem.
Customer put gasoline into their transporter (mercedes sprinter), drove away, car stopped, got towed to my buddys shop. they only flushed the system, and after ~70k kilometers they had a engine failure because one of the injectors started leaking.. unnoticed. And they sued the shop. (the sue is still going btw).... so humble mechanic has a point of changin the hole system.
on the other hand, they had countless times where they just flushed and nothing happened over the years.
I like the Humble mechanic and I like engineering explained, I am a VW guy and have been for over 15 years but this video just got under my skin. I've been into tuning and building TDI's specifically for about 10 years and I truly think this is a little excessive. This is also the reason I stay as far away from any dealership as possible.This is just my opinion and I do not disagree with many of the "possible" problems this "could potentially" cause but to approach something like this in such a drastic manner right out of the box just seems a little over board to me. Needless to say, good video like usual, keep it up.
AdrenalineJunkieProd u
As somebody who works at a dealer, Volvo to be specific, and has done PLENTY of incorrect fuel jobs. We usually, activate the fuel pump, pump all of the wrong fuel out (to get as close to 0 fuel as possible, if not possible tank may be removed to remove the incorrect fuel), change the filter, fill the tank with the correct fuel, and so far, had 0 issues with D5's that I've seen cover 150k since the incident. Did however have one that had a funny issue, but supposedly never incorrectly fueled but it was a possible source of the issue, if that makes sense? But otherwise no issues at all. We realise, because it makes sense, that the components on these cars were built to handle a lot worse scenarios than this and it won't just kill them suddenly. Maybe VW's use terrible fuel pumps but idk. Least as far as Volvo is concerned never been a problem.
Interesting video, but i cant help but think thats utter tosh about the necessity of the expenses involved in this. I put petrol in my diesel van and drove away until it literally died in the middle of a junction. The recovery vehicle came and took it to a garage that can fix this problem and it cost me £30 - thats like $50. Never needed anything replaced.
My workmate then did the same again in the same van about 8 months later (and about 15k miles) and again, £30 to remove petrol and clean the system. Never had any problems in the following years and 60k+ miles till i traded it in. I know a few other people who have done the same on rare occasions over the years and non needed any parts replaced or ever had any related problems.
How you could justify changing the entire fuel system at a cost of $8000..... blows my mind.
It also happens way more often than you think - especially if you drive a diesel for work and a petrol at home. A friend did this at xmas, and when the recovery guy came he asked if this happens a lot and he says this was the 10th call out of this nature in a week!
My friend told the recovery guy he felt really embarrassed as this was something a woman would do and the RAC guy said that 9 of the 10 people he helped were males lol.
modern deisels have basically no tolerance for misfueling, but old deisels could run on a mixture of vodka a sticks and wouldn't break.
Halofan830 My van was a 2006 dont know if thats old enough to have been/not have been a problem.
+Marc Gooding (marcoboyle) Mine was a 1980 Rabbit, but did the same thing and never had another problem!!!!
+AspergerDad Yep!
I also just got my RAC breakdown cover renewal through and read through it and it specifically states that they will help if i put the wrong fuel in and pay for everything. somehow i dont think its standard practice to change all this - otherwise there is no way that would be offered for free on a $80 a year breakdown policy.
+Marc Gooding (marcoboyle) Diesels in EU have smaller fuel nozzle and on the gas stations the petrol one is wider, meaning its really hard to do it accidently. Even putting the diesel nozzle in a diesel is harder, at least for my car. I often have to really try to put it inside.
I like the collaboration between you two. Someone who's got knowledge from hands on work and someone who's got it from studying is a good combo.
New fuel pump - $200
New injectors - $200
New new filter housing and high pressure lines - $200
Cost of work - $200
Disposing fuel at oil refinery - they pay YOU $0.1 per gallon
Total profit - $7200.
Ma samo se promeni filter i ispere rezervoar dizelom. I to je to, ne znam zasto ljudi potenciraju i dalje na ovolike skupe popravke. U svakom slucaju moj ceo auto kosta kao pola ove "popravke".
Where ya getting a fuel pump for a diesel for 200 dollars id buy 20 and resale
Where are you getting high pressure common rail diesel injectors for that price? Even my old Bosch injectors cost more than that.
Or just put the gas in your lawn more or sell it to a friend lol
@@wvboy0311 right? The injectors for my truck are $1,200 lmao
Complete bs. Did it to my Ford f350 . Went to the dealer after driving about 10miles They drained the tank , replaced the filters, and I was good to go . Cost about $250 and $100 worth of gasoline. This
Yup. Seen lots and only a couple had issues and needed a full system replacement. Worth trying, since the only other option is full system replacement anyways.
How's your truck?
Assuming what this guy is saying is true, what plastics and elastomers do they use in diesel fuel systems that are reactive with gasoline? I find it a little hard to believe all that needs to be tossed after a relatively short exposure to a mixture of diesel and gas.
It's less the exposure to fuel and more about the contamination of metal from the HPFP.
+HumbleMechanic
Seems as though it would be prudent for manufacturers to install a high pressure fuel filter down stream of the HPFP.
That would help mitigate fuel rail and injector replacement from all types of fuel contamination.
Same could be said for an in tank or post lift pump fuel sensor similar to a Flex-Fuel sensor on gasoline vehicles to quantify ethanol percentage that would alert the ECU of water or gasoline contamination and shutdown before post lift pump and primary filtration contamination can occur.
+patw52pb1 Some diesel fuel filters, Chrysler is one, solidify (melt) if gasoline comes in contact with them so no liquid will pass through them and they are, of course, placed upstream of the high pressure pump. For those not knowledgeable about engines, this causes the engine to stall as a result of fuel starvation and all that is necessary to fix the problem of mixing gas with diesel is to drain the tank, blow out the lines, replace the fuel filter and possibly prime the system.
Buck0338
I am aware of genuine Chrysler/Mopar diesel fuel filters on the RAM and Sprinter series that swell and clog in the presence of water by design, but I am not aware that they will "solidify" in the presence of gasoline.
Do you have a citation that supports the premise that the filter will solidify in the presence of gasoline?
Buck0338 I was wondering about the filter housing and hoses more than the disposable element itself. It seems to me like an unnecessary expense to throw away that too. It would be like throwing out the airbox when you change your intake air filter.
We have 2 tankers for fueling equipment where I work, 1 gas and 1 diesel. Aside from the nozzle color and placards, they are identical. One day I must have been in outer space, and I pulled up to the wrong tanker and managed to pump about 20 gallons into my Ford Powertsroke before I realized what I was doing. All I did was drive it over to the shop, empty the tank with a transfer pump, and fill it back up with diesel. Still going strong to this day. Replacing the entire fuel system seems a bit overkill...
Your Ford Powerstroke heavy duty has different tolerances (and is heavy duty) than a modern volkwagen passenger diesel system. Please don't compare the two.
He isn't wrong though. So the comparison is correct. One of my first bought cars was a 1999 Diesel Volkswagen Jetta. My girlfriend at the time mistakenly put gas into it, a quick run to the local mechanic to drain the system and throw in a new filter did the job just fine. To this day the car still runs solid. Generally speaking, unless the mechanic is a friend, a mechanic will typically try and nickel and dime every avenue to maximize his profits.
Fast forward to now, my 2010 Volkswagen Passat Diesel, I mistakenly put diesel into the tank after I failed to properly read the label (didn't help that the marked diesel was blue and not the typical green or yellow). Again, a trip to the local mechanic to drain the system, new filter, all is said and all is done. 6 years later, the car still works beautifully, no issues.
Uninformed people are usually the ones to fall victim to those trying to shove their hand into your pocket/wallet as deeply and greedily as possible. People with a general lack of knowledge about certain things will normally always follow a mechanics say-so, without actually questioning whether or not it is needed. When a person is being informed that their vehicle needs whatever in order to function properly, and the person informing them is someone that is most qualified at what they're supposed to do, it becomes abundantly clear to the uninformed that is what they should do - even if it's a huge cost.
Some people don't realize what they've done. Far more often is that you pull up to a full serve pump and the gas jockey fills your diesel with gasoline, then you drive 100 miles down the highway to get home and your truck never starts again.... RIP duramax
So yeah it depends on how much goes in really. Driving it 500 feet, it probably isn't even going to start to eat that gasoline.
Be careful. I nearly put E 85 in my diesel, because the pump handle was the same color as diesel.
Les Brown
I can't just shut down and spend an hour draining the tank in the middle of an active AOA. My shop is about a quarter mile down the airfield from our tankers, and hunting down crew to help tow a truck can be difficult. I did what I had to do. Yes, it still runs just fine. That was over a year ago.
understand that these guys "play it safe" at the customers cost!
just drain that tank and refill call it good if something shags out later on then replace it..
Of the 20 or so I have replaced exactly zero were paid by customer. It was either VW or insurance paying the bill. When VW pays they bill, they decide what needs to be replaced.
+HumbleMechanic I have seen VW hand a customer a bill for this. Maybe its different over there but here neither VW or insurance will cover owner abuse (unless its specifically mentioned in the policy)
+ItsFriscoBaby I am not sure that you having 2nd hand experience with one situation gives the full view of this issue. I have personally replaced a hand full of these systems, and seen many more replaced by the techs I work with.
I also wonder how much experience you have in dealing with these parts failures for whatever reason.
Who knows, maybe that dealership didn't follow the proper protocol. I wasn't there so I am not going to speculate. :)
+HumbleMechanic That's the second time now you have jumped to the conclusion that I have never touched a system that had petrol put through it. The 2nd hand information was a quote from a VW main dealer for the repairs. The customer had told them where to go. Why would I think the customer faked the quote?
+HumbleMechanic Oh and while we're talking about the gospel according to vw do they still say that 1.9pd heads can't be skimmed?
this is a joke....drain the tank, put diesel back in and you're fine.
Garages scam you every time, try to do as much as you can yourself. Just search for some help on google and you will be fine most of the time
I think he was talking about when it goes beyond dangerous. A Diesel Engine is not designed for Gasoline. If you catch it right away, yeah, drain and be good. If you don't... and your engine doesn't work anymore, then you've got problems.
Like he mentioned though, it may not be immediate, but often times, it can lead to a way more expensive repair down the line. Moral of the story though, don't fill your diesel vehicle with gas!
Yes. Be clear and Always warn about potential damage or life shortening of components.
Could the manufacturers develop a sensor that detects gasoline as it enters the filler pipe or tank? And once the sensor is tripped it disables the car before damage is done. Gas gives of plenty of fumes, can't be that difficult to invent a sensor to detect it. Then you would only have to pay to have your tank drained.
Yes but why would they want to lose possible business fixing it?
Agent Office
Sadly i think you are correct, i can think of no other reason why something so simple is not available.
+100SteveB and in 3 years when the sensor fails in the middle of nowhere and leaves you stranded you'll be the first to complain about unnecessary and overly complicated electronics on modern cars and how they render a car useless.
Jo TUWE
Well, yes, it would add yet another sensor to cars that already getting far too complicated, but seeing that a gas sensor is not vital to the car running correctly, they could simply fit an override, either a switch somewhere, or have it somewhere in OSD menu. If the sensor fails it could easily flash the fuel warning light to let you know what the problem was. And unless you had just dumped a load of gasoline into the tank, you would know it was a fault and override it. Quite simple to implement, but like the previous poster said, why would manufacturers want to build something into a car that could lose them thousands of $ in repairs.
+100SteveB Sounds like a pretty good idea. Why don't you develop an aftermarket device? Maybe something to insert in the fill line that would start beeping or shut the line if it detected the wrong fuel? How hard could it be?
Wow. You guys are crooks. That's utterly ridiculous to change all those parts out. I hope nobody ever brings a car in your shop for that.
You bring the car to the shop for an oil change and end up changing the whole engine.
Don't put gasoline in a diesel engine then dipshit lol
It's the VW way; "Ve have vays of making you pay!"
😂😂😂
Right when the cost was mentioned, I was remembered again why I stepped away from VW cars and engines years ago...
They were already expensive to maintain mediocre crap when a lot of people still believed in 'german quality', let alone today...
I'm not in a position to quote VW repair costs, but replacing an entire fuel system in any car is not going to be cheap...
+Engineering Explained I've had a VW and an old Volvo with the VW 2.4 diesel engine, among a selection of other random cars... While not the least reliable, the VW and VW powered Volvo were certainly below average, and the costliest to keep up with on year basis.
Even my current lemon costs me less while being twice as much in the garage...
The VW's don't break down that much, but it's always the expensive stuff...
+Candisa Are you from US? If you are, i feel bad for you, you guys get the crappiest versions of European cars over there. It seems the quality drops significantly once they go over the Atlantic.
+MyRealName I'm from Belgium...
+Central Intelligence Agency Yeah, not liking VW's is very typical for Belgium... That's why half the cars on the streets here are VW/Audi/Skoda's!
Smartass...
In 1972, my mother had a 1970 Coupe DeVille with a huge 500 CU motor. We were on a trip to a relative in another state and mid -trip she pulled into a gas station to fill up where an attendant pumped the fuel for you (before DIY pumps existed). The kid put diesel in the Caddy. We started down the road and after about 3 miles my mother complained that the car started feeling sluggish and there seemed to be more than usual smoke coming from the exhaust. Fortunately we had a ticket for the gas sale and right on the ticket was the price per gallon. That's how we knew it was diesel because in those days when Gas was 102 cents per gallon, diesel was 89 cents. I'd worked in my late teens in a used car lot so I new a little about car motors and I knew that the Caddy had a 10.5 to 1 compression ratio so I said "Keep going and don't stop" until we had less than a quarter tank on the fuel guage. When we pulled into the next station we didn't turn off the motor and filled it up with 93 Octane. We did the same fill up one mile from our destination. We then arrived and told our relative what had happened. He said it was the best thing we could have done and we turned off the car. The next day the car started up without any problem at all.
I don't even own diesel. Why am I watching this? WTF am I doing with my life?
You wanna know stuff
I do, my F350 dually diesel pickup truck.

made me laugh this comment 😂
@Geoffrey Cass I can't be arsed 😂
At 8:50 it's mentioned that on the older diesels, one could get away with gasoline in the diesel - YES. From the "been there, done that" files, a truck with an 855 Cummins 250 ran out of fuel 200 miles from the shop on a Sunday in the Midwest decades ago, so with the diesel from the service truck and a local gas station, we ran it on an 80/20 mixture of gasoline/diesel, engine oil. Low power, but it arrived at the yard suffering no damage.
Can't do that these days though!
high pressure pump is the only worry. electric pump will be fine. if you change the parts he suggested my as well by a new car.
"You math, I don't math" and "I wore gloves because I was afraid of touching ACTUAL parts" I had a good hearty chuckle at both
I wondered with that... lol.. was afraid of touching "actual parts"??? I don't think he has ever worked on a car!
Guys search TH-cam for this. There's a video where this is intentionally done and the car is fine after putting the correct fuel back in. This is a huge scam for mechanics that charge so much money to replace and clean everything that isn't even needed.
Having done a about 20 of these repairs let me tell you this. If I was going to "scam" it sure as hell wouldn't be this. There are way easier ways to "scam" than a high dollar repair.
Also what you probably don't know is, VW paid for all but 1 of these repairs I did. The odd ball was paid by insurance company from a fuel station.
Lucky for my customers I don't scam them. That's a quick way to have your ass on the street.
Like some other commentators... I find it amazing you are replacing components that don't need to be replaced...best case scenario is drain the tanks crack the fuel rail clean out the lines it would take a lot of cranking to wash the bore to cause any really significant reduced "life" that anyone will notice...
Scary thought.
Some people have put diesel in a petrol engine
I dont know how people have done this as the diesel pump nozzle is larger and wont fit in a petrol tank filler nozzle
+IIGrayfoxII I once did it when I owned a moped, but that's because I used a jerry can and was told it contained gasoline. I trusted them enough not to smell it, boy was that a mistake.
Didn't get damaged though, it even fired a few times before I had my "oh shit" moment.
+IIGrayfoxII I almost did this the first time I filled up on my own. Grabbed the nozzle, go to insert, *clunk, clunk*, "Huh, doesn't fit," look up to see the word "DIESEL" on the pump... I drove to a different gas station to hide my shame...
+Tim Bayliss I came home from work one day and my wife was cutting the grass. I said to her, "Where did you get the gas?" because I knew that we did not have any. She said, "In the blue gas can." I told her that was kerosene and she replied, "No wonder it was so smokey." I quick started the lawnmower back up, leaned out the carb and ran it out of "gas". I had long wondered if kerosene would work in a lawn mower as long as there was gas left in the carb to start it.
Buck0338 Man it's quite impressive how many kinds of flammable fluids an engine can run on, even though some may damage it.
+SnOpeK Domowei Kerosene most likely won't actually damage an engine beyond creating excessive carbon deposits as it's more of an oil than gasoline.
or in fact depending on ratio of diesel to petrol and capacity of tank (how much space is left) topping up with diesel and driving gently for a bit normally gets you through . You may have to crank engine for a while to get it started again but really no damage is done
Someone post where this guys work so we never go there.
I had a sprinter van I put petrol in so 50/50 mix of 40 litres. Drove 500 miles filling with diesel on route.
It’s now at 170,000 miles . No issues a year later
must work at a dealership- solution to everything: LOAD THE PARTS CANNON!!!!
What I got from the video is that vehicle manufacturers make profits from consumers making mistakes... Manufacturers are making parts that WILL be guaranteed to fail if used incorrectly once. With your own words older vehicles ("back in the day") would just run like crap for a bit and replace maybe 1 part but today it would destroy the whole fuel system / vehicle.... especially in terms of the money needed to replace all parts "damaged" either short or long term will exceede the value of the vehicle. It's awesome to know you guys explained how inferior vehicle parts are made and how making something like a gaspline pump that doesn't rely on fuel for lubrication can be fine but if you have a diesel pump and give it gasoline it will destroy it. Why cant a gasoline fuel pump be used in a diesel? I think manufacturers plan for cheap / obsolescence / high cost of ownership.... especially when dealerships make more money off out of warranty claims / repairs keeps them in business more than selling a new vehicle.
This is a classic case of (cost of repair far exceeds value of vehicle) scenario.
its like this, diesel depends on a sort of detonation or ignition from hot conditions, and gasoline is formulated to prevent detonation from hot spots so really they are opposite fuels. the operators manual for the 1977 diesel i had said in very cold weather mix 50/50 diesel/ gas
y not replace the car?
its actually commonplace in parts of the world with very harsh winters to add a bit of gasoline to a tank if diesel so it wouldn't solidify as much overnight.
My '84 VW Turbodiesel actually had a table in the owners manual for how much gas to add to a fill to keep from gelling up. Up to 10-12% if memory serves (sold car 10+ years ago.) Newer common rail systems are a whole other world of pain as far as what they will tolerate. 29,000 psi at the nozzle (not much room for contaminants..)
at 6:37 he says "Were pumpin 800 bar through these" NO WAY!! Maybe he means 80? The pressure at time of combustion is likely near 37 bar, as that is what it is on small 4 cycle marine engines.
+BiddieTube diesels have very, very high fuel injection pressures.
Modern diesels can have more than 1000 bar fuel pressure. Petrol on the other hand uses lower fuel pressure. Maybe you are confused with that?
Well, I done some research, and quite surprised. Some car and truck diesels may have well over 1000 bar fuel pressure. I just would have never thought anything for consumer use and repair would involve pressures that great. One can get quite well injured or even killed messing with that. One sure better not ever attempt to use any replacement parts not specifically designed for the application.
+BiddieTube Luckily the pressure bleeds off when killing the engine. So it's not a hazard when working on your car. Also you shouldn't use parts from untrusted brands in something as vital as a fuel system :p .
The amount of fuel that gets compressed is tiny and the compression doesn't stay if you turn off the engine.
Maybe it depends with the type of engine that is it made of strong or weak materials....but the point of lubrication system is true ...the metal fragments....
I admit I did this with my work truck. We had Gas Ford trucks for years and they switched to Diesel Chevy trucks. Now I had it for two weeks and was fine but one morning I was tired and on autopilot grabbed the Gas pump. It was a 30+ gallon tank and I had maybe 2 gallons in it when I filled it up. Luckily as I was putting the gas cap on I realized what I had done. I never started it. I rolled it out of the way and into a parking space and called local shop. I work in the oil and gas industry as an I.T. Tech so this was quite embarrassing.The local shop tried to tell me it would be about $6000 and that they had another rguy with the same truck do the same thing. I explained that I was familiar with cars and work on them at home. I explained that I had not started the vehicle and all I needed for them to do was drain the tank. They charged me about $500 and replaced the fuel filter even though it didn't really need it but whatever. I also noticed they did not put the gasoline in a special disposal tank but rather a couple of old oil barrels, put a piece of plywood over the top and left it there. It took forever to drain the tank. As I was paying I ran into another guy that works out of my office and he was there for the same thing but he drove it till the engine crapped out. He had to pay $6000 out of pocket. So its a huge difference to drive it and to just have it in the tank for sure. I went online and purchased those big green "DIESEL ONLY" stickers and put one right on the gas cap door so I wont forget again.
My father accidentally put about 1/2 tank of gasoline in his 1980 diesel Oldsmobile station wagon back in the eighties. Once he realized what he did, he filled the rest of the tank up with diesel fuel, drove it till he could burn off some of the mix, and added more diesel, and slowly diluted it till it was all diesel. Apparently, it never damaged the car, as he kept it till 1986 and put close to 200,000 miles on it. Sold it to a volunteer rescue squad that put another 100,000 miles on it before the injector pump finally failed in the late 90's...maybe that 1 tank of fuel made it fail?, but the car lived a long, useful life, which is really saying something for an Oldsmobile diesel!)
You only need to empty the tank and fill it with diesel again... Flushing with brake-cleaner and replacing almost the whole fuel system is not needed. A little gasoline will not hurt the engine.
It's not the motor/engine they worry about.. it's the fuel system, it's bolted to the motor, the fuel system is a separate assembly.
With new common rail diesels, it's a whole different ball game to old school diesel system. Much higher pressures involved, meaning greater strain on everything to begin with and with lack of lubrication from petrol/gasoline, it gets worse. If the vehicle is driven too far with petrol/gasoline, it can quickly cause damage(it's like running without motor oil). If it's not driven at all and barely runs, it should be fine with a drain, flush and refill. Is there $8000 of parts and labor??? It depends on the manufacturer, the damage and whether genuine or after market parts are used. If it's under warranty or you go to a dealer, you can bet your life it will be genuine parts!
If you have an old school diesel with the gear driven, inline injector pump, running petrol, isn't really a problem....
Got my Peugeot 504 in 1961. Around 1979 my wife topped off a half tank with gas. After a few days it ran crappy. At half a tank I put diesel in and it ran better. Within a month it was back to normal. 2016 and it is still running great. I changed the filter about 6 times and the injectors once in 2002.
When he said "If the customer had to pay for it". Does this mean the manufacturer covers this under warranty typically? Seems awfully nice of them.
+FrugalPrepper Every system I replaced other than 1 was covered by VW. The other one was paid for by insurance of a fuel station for misfueling the tank.
Years ago, I had a Jetta diesel. I was given a "bulletin" from the VW dealership about cold weather fueling. They actually recommended adding a few gallons of petrol to the tank & top off with diesel to prevent "gelling" of the fuel. I did it. With no issues... Just sharing my experience...
I am not gonna pay someone to get rid of a fuel that lots of folks would use to start a camp fire anyway. And honestly how many folks care enough about the environment to actually pay $25 a gallon? I would venture to say far less would actually do it when it is real money than how many would claim so when it is theoretical.
I would never use gasoline to light a fire, again. Unless you're on a beach or out in the desert with no vegititation.
+Eskimo227 Its diesel diluted with gasoline. It doesn't flash up like gasoline does. Wouldn't be much worse than Kerosene. I've used gas, diesel, kerosene, used engine oil and never had an issue for fire starting. Its not good for the ground but still. Don't be stupid and use only a little bit. Like 1 cup at most.
Everyone here complaining about the cost of replacing this system and questioning why the dealership would even bother replacing these parts has not worked in a dealership before. They're covering their butts as well as the customer. This man explained the exact reason as to why each one of these parts is replaced, sure you can half ass the process and replace one piece or nothing at all and hope for the best or replace what could be affected and know your customer will be safe and satisfied and you won't have come backs wasting your time and money. Because at the dealership you're diagnosing and replacing parts for free once the customer comes back complaining that after you worked on the car it didn't work right.
Instead of paying for disposal, Couldn't you pour it in a shop heater? When I worked at a classic car museum we used to take our waste oil and give it to the garage across the street and they used it to heat the shop. This was just waste oil though, not sure how those shop heaters handle gasoline/diesel mix
Petrol in a diesel does not need the whole fuel system replacing. Where I work we replace the fuel filter (but not the housing) drain and re-fill the tank and blow the lines out. 9 times out if 10 the car is then fine. The 1 time in 10 is where the car has been driven some distance, and in modern engines this tends to melt the fuel-injectors and wreck the engine. Diesel in a direct injection petrol engine tends to have the same effect- melted injectors and holed Pistons.
This is all BS. I own diesels and gas burners and I was the shop foreman for both Ford and Chrysler. WE drained the tanks, we siphoned the gas off of the diesel and split the gas between all of the techs and we put it in our own cars. Then we put 5 gallons of fresh diesel in them and bled the lines till they started and sent them out the door. They never came back. Never had a problem. I even watched a guy put 5 gallons of gas in a 45 gallon diesel tank to keep it from jelling during the winter. Never hurt that Mack truck with the inline 6 turbo not one bit. Wished we got 8 grand for 60 bucks worth of work.
I had a 2007 Jetta, was in a snow storm and accidentally filled about 2/3rds of the tank with gasoline. It ran 9 miles until the first stop sign. Eventually got it back to the house.
Siphoned as much fuel as possible out of the tank as I could, about 5 gallons which I put into a 96 Grand Marquis (that 4.6 is such a great engine, it will burn anything! )
Refilled the tank with diesel so it was about 2/3rds diesel mixture. It started up!
I let it run a long time idling so as not to put strain on the engine, when it was down about 3 gallons, I put in 3 more of diesel, then just drove it, never having a problem.
Interesting so putting diesel in a gas engine is a minor issue yet seemingly a huge issue when doing the opposite, and YET, they made it so you can't fit the diesel pump into a gas tank but you can fit a gas pump into a diesel car. Why didn't they do the opposite?
More people drive gasoline cars over diesel. The consequences of putting diesel in your gas car might not be as bad as gas in a diesel but you'd have WAY more people making the mistakes.
In the winter in cold weather my old 240D Mercedes manual said I could cut the diesel fuel with a bit of gasoline in the winter. I think it was about a pint or quart of gas per tank of diesel fuel. Diesel fuel gets like gel in winter.
Will there be a video on what happens when you put diesel in your petrol car?
+Ethan Gee no but there is a blurb about that scenario at the end of this video
I'd like to know also, but my humble guess is it will stall and might knock because of the lower octane rate. It might also block the filter because the diesel is thicker. I'd replace the filter and clean the injectors.
Just won't run at all. You pull the plugs and blow out any residual fuel. Add a little oil to each cylinder to overcome cylinder wash. Purge the diesel out of the fuel system then fill her up with fresh gas and they usually start right up. They smoke for a few minutes but I have never seen any permanent damage unless the customer keeps cranking the engine for an excessive amount of time. But usually the battery dies before that happens. My shop is in Florida and every year when the snowbirds come down a couple of them will put diesel in their fuel tanks by accident.
Yea, I can see that at an empty tank filled with gasoline - to an extend. However, it is known that in winter, in some countries, some people use a 70/30 Diesel/Gasoline mix to keep the fuel from freezing up. The filter will be just fine - so will a lot of other parts as long as there is not a substantial amount of gasoline without any diesel ran through. Remember 2-strokes? They have a 1/50 oil/Gasoline mixture and run no oil in their housing - and do just fine with that lean mixture in a triple RPM range - Diesel cannot go beyond 4800RPM because it does not ignite faster. So, if your engine stalls because that happened, I would call that overkill. It is not the same as running all components for 30min without any lubrication since gasoline lacks the energy to self-ignite.
Yes, I am not a mechanic. I just worked for a parts developer for the car industry in Germany in a prototype/testing shop with about 30 masters mechanic and about 100 engineers and in high school, I did my practicum in a mechanics shop and we helped guys that ran out of Diesel all together - and that is without any lubricant for sure and the engine (TDI) was just fine with starter spray. Yes, you can have trouble down the line, but you don't automatically replace your rim because you had a flat tire either: Yes, it could be damaged, but chances are in most circumstances it is not (if the rubber did not flake off yet).
"unregardless"
I am impressed. Succint & concise. These young men do a nice job with these videos. Nice to see clear minds on display.
or you can just drain the gas run the fuel pump manually with diesel through the lines to purge the gas, fill it up and hope its okay before complete fuel system teardown.
im a BMW mec and thats the way to do it fuel line of activate fuel pump and empty the fuel cell and add diesel and it runs
You or I certainly can. A professional independent mechanic does not have that luxury. The risk of metal flakes in the fuel system, which (as he pointed out) will destroy the engine if it jams an injector open is unacceptable for somebody who is accepting payment from a customer.
I had that issue on a new diesel car and we just clean completely the engine and fuel tank, got new filters and the car is runnung well until now 8 years after .. Most of the procedures you said won't be necessary, in most of situations .. Any one would shut down the engine on malfunction situation, unless you're running the engine with gas on purpose.
Good video By the way. Thanks
I was taught that putting the two together created an air fuel mixture issue creating a higher degree of hazard.
That diesel by itself was too lean for combustion and gasoline was too rich, mixing the two created a more volatile situation not only for the engine but for the storage and handling. Ignition sources can come from many unexpected places, like some Knucklehead thinking he can smoke around it because he's done it a thousand times either gas or diesel, or some other unforeseen event.
Either way I definitely appreciate the insight to the internal mechanical aspects. Two Thumbs Up 👍🏻👍🏻.
The old truckers used to mix gasoline in their diesel engines to thin it out and prevent the fuel from gelling in the winter time, roughly 5% I think. By all accounts I have heard, the truck would run just fine, no noticeable difference whatsoever. I realize you can't do that now with all the emission equipment, but I'm pretty sure they still mix in some kerosene for the same purpose.
Thank you for making this comment, I'm thinking of doing this but for a different application :).
In South Africa, we would just flush the system
depend how much ratio between diesel and petrol you pump in... sometimes we pump petrol maybe 50liter diesel with 2liter petrol to clean the fuel system..if worries about lubricate..add some 2stroke engine oil
if you are lucky you can just drain the tank change from gas to diesel and just pull the injectors and crank the motor untill you just pump diesel.
why would i pay someone when i can fix it all myself.
+Trent Nelson No one's stopping you from paying about $4000 for the parts.
+Trent Nelson It's a personal choice.
The issue is that if anything goes wrong down the line it will cause further need for repair, and possibly more damage to the car, making the repairs more expensive. If they're already pulling your car apart to clean all of this out, they may as well replace the parts that might require them to do that all again, or cost you more money down the line, especially since any effects down the line could make them liable for the damage.
And as for whether that's a good decision, the bearded guy said in other comments that the extent of the repair is mandated by VW, and often covered by them, and that if he deviated from it, the liability would be on the business instead of VW.
As for people confused how you get $8000 out of $5000, four things: Rough numbers, running a business is expensive, businesses need to pay taxes, and businesses exist to make a profit, not operate at cost.
Got a 2001 Seat Leon TDI 170K miles on the clock, filled up petrol (7litres), topped up with premium diesel, car was running like crazy, different smell, less rattle :) 15K miles later so far so good
I've had hire cars come in with full tanks of petrol multiple times. I always just pump the petrol out and refill with diesel. Pump the lines for a while and then restart the car. None of them has had a fuel system failure and many have done over 40k miles since.
He is an honest man. A nice man. End of story.
If it happens to you, drain the system, change the fuel filters, refill with diesel and carry on as usual. Seen this happen way too often and the engines go on having a long life.
.
He is a great mechanic that knows his stuff,also very humble and seems like a down to earth kind of person and who cares if he is not the best in math,he is certainly not a cheater and no one is perfect .....i wouldn't mind bringing my cars to be serviced my him.
I mean the parts you suggest need replacement "just in case something maybe possibly might have happened to it" is, at this point, laughable.
Do you expect someone to sit there for like 15 hours trying to crank the car with the wrong fuel. The "humble" mechanic. Sure.
If every mechanic did his job as bad as you, i'd be paying 15.000+ every time i visit a shop for a minor repair, because he just replaced every part in my car cause there "might possibly be something wrong with it in the long run".
The best advice, look at what's written on the pump!
This is unbelievable.This is ripoff.I have been working on German cars for 16 years and have seen this few times and never had do charge somebody more than few hundred dollars .This guy gives honest technicians bad reputation
3000 in fuel disposal that would be 120 gallons or 9 full fuel tanks
And if it was that expensive I'd be like "okay, give me the fuel and I'll dispose of it."
You either siphon the gas off the diesel since they will separate, or you just burn it and move on.
I had a rabbit diesel in the 80's, user guide said add up to 25% gas if you drove hot weather fuel into very cold weather to raise the pour point. cold weather fuel has it already. Old school vs new, no electronics, loose clearances
Why not just buy a gas engine and save the the tank and fuel.
I’m one year late on this comment but I just wanted to let you know that I died reading this 😂😂😂
😂😂😂
I live in Australia where many cars (but not as many as Europe) and virtually all pickups and most SUV's are diesel. I have heard that you can add engine oil to the tank if you misfuel with gas, sort of like a 2 stroke mix. Also heard of misfueling by lending car to others but car carried on as normal with no problems but I guess it depends on how much diesel was already in the tank.
this is why you do your own mechanic work . these guys will screw you every time.
Ifr you do your own work, you don't fill the wrong fuel in the first place.
Depending on how much gas I had pumped in (say 25-50%,) I’d just fill the rest up with diesel and send it.
once made the mistake of putting petrol (as we say in the uk) in a car that takes diesel. As soon as I realised the error I topped it up with diesel. So their was a mixture of the two types of fuel. Accelerating in lower gears and keeping the revs high will burn out the fuel. I topped up with more diesel and problem sorted it self out really. I am not recommending this to anyone but it worked for me. Saved some money which otherwise would have been spent in a garage.
What about diesel in a gas?
It's mentioned at the end of the video. Charles says it's not as bad and would probably cost under $500.
Diesel has more lubricants than gas so if you put diesel in a gas engine you have more lubricants in the system. For the most part you're just draining the tank, flushing the lines and replacing the filters (unless you drove a long ways).
The reason why putting gas in a diesel engine is expensive is you starve the pumps of lubricants causing them to break meaning much more costly repairs.
My 79 Mercedes indicated in the manual the up to a 50% mixture was acceptable in the winter to keep the fuel flowing.
Who cares about the aftermath of gas in diesel.......what happens when you start a diesel full of gasoline?????
clogged injectors
Have done it, am a tech at a Volvo dealership. Believe it or not, a diesel depending on the design will run on gas/petrol. Simply drain tank, replace fuel filter, refill with fresh fuel and send it on its way. Haven't had an issue yet and have done hundreds of them this way.
I don't know about the US, but in the UK most garages and vehicles have changed the design of the fuel filler. You can no longer fit the hose from the Unleaded pump into a diesel car and vice versa. I'm also not convinced you need to do this amount of work for a small amount of cross contamination.
Moral of this story, don't buy a Diesel VW. Actually don't buy anything VW. If for some reason you do, don't take it to a VW dealer for repairs.
So, funny I've never pumped the wrong fuel in my life , then again I actually pay attention to what I do. Paying attention to things helps you a lot in life.
What a scam--flush the fuel, change the filter
my buddy had a 97 chevy 1 ton with the 6.5L diesel, he picked up fuel that had soap in it so it was chuggin for a few weeks. He added fuel additives to help kinda get along because he knew the injector pump was fixin to go at anytime so one day when we filled up he put 1 gallon of gas. the gas was to eat at any debris that wasnt supposed to be there out, which it worked for a few more weeks until he hooked up to a gooseneck trailer with 2 tractors on it and that made the truck try to runaway from him. But in short its a old trick to use a small amount of gas in a older diesel in certain situations
Engineering Dude ! Quit stepping all over Humble Mechanic !!
So, I was in UK last summer and inadvertently added petrol to diesel car. Fuel nozzles are different colour there. Drove about 10 miles before I realised and called a specialist service company who connected pumps to car fuel system, drained everything and replaced with new diesel. Car was ok thereafter. Must happen a lot over there as technician came with fully equipped fuel exchange truck. Gas stations keep business cards on counter for such cases.
If you notice your engine knocking and banging and shut it off right away the damage is typically negligible. The fuel pump will typically release metal shavings throughout its lifecycle, normally they will go back into the filter through the pressure relief valve and be safely captured. This is why some engines require the fuel filter housing to be completely removed and cleaned when changing filters, otherwise the now agitated swarf from the bottom of the housing will go straight back into the pump and wreak all sorts of havoc. When you put petrol in that pump it releases a whole lot more swarf and that's when all the problems start occurring
This video is awesome. So much info, and will help a lot. I knew the perils and fixes for the old mechanical or VE pumps systems but haven't really known what all needs to be done in a CR system. Thanks for the upload.
Which kind Of liquid You can clean the diesel tank?
I usually just hook an old fuel pump to the fuel line coming out of the tank and pump all the contaminated fuel out , replace the fuel filters, and blow all the lines out. The shop I worked at we charged $500 for that service, including disposing the bad fuel. The service writer would of course explain to the customer all the potential problems that could happen as a result of using contaminated fuel--damaged injectors, fuel pump problems, high pressure pump problems, ..ect. It is important to make sure the customer knows how many problems can happen as a result of using bad fuel!
I put gasoline in my Jeep Liberty CRD all the time...
But I did remove the 2.8L VM-Motori diesel and swap in a 3.7L gas V6 due to the VM-Motori diesel being a troublesome design.
I do have to worry about others putting diesel in by mistake since I left the diesel fuel cap and *Diesel Only* decals in place. Another reason not to loan out vehicles.
