Putting Gasoline In A Diesel Car - What Happens? (2023)

Introduction

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.

Hands of more than hello.

Everyone and welcome this really talking about what happens when you put gasoline in a diesel car now, why you do this, you know, there's, not really a good reason, but someone might know by accident or maybe intentionally, or maybe they just didn't know when they thought any fuel work.

Absolutely, you know, we've seen sort of all the range of people, miss fueling their cars anything from some gas stations have green punk covers for diesel and some have yellow.

So that's, a confusing thing we had a customer is low in their car out to their friend.

And the first tho up their friends doing a real nice thing, build their little their car tomorrow, their car, and they did a real nice thing by friends and their friends filled their car with gasoline on the very first bill up.

And we've even had where they just didn't want to they did it very possible? Sometimes you don't want the details.

But the point is is that you've actually dealt with this shop anytime, you know, you have to take care of it.

And so we're gonna do is walk through the different components and what will fail and what you'll have to deal with when the customer brings in the car that has done this yet so get started with the fuel tank.

Does anything bad happen if I stick diesel fuel and gasoline in a diesel tank generally with the tank itself? Nothing bad happens.

It's it's, a plastic tank.

So not really plastic, but composite it's, a composite.

Thank you.

And it holds up just fine to gasoline.

What we will do is remove the in-tank pump and clean any remaining gasoline out of the tank.

Ok.

Now that in turn pump as you mentioned as anything having with that are you? Can you still reuse it? Most of the time you can reuse the in-tank pump.

It really depends on how much gasoline was pumped through it isn't that usually depends on how long the car was cranked.

Well, not starting because it was ok.

So from that intent, palm pilots traveling through some people lie to the filter.

And as far as a few lines themselves is there any problem with gasoline and diesel fuel lines.

Now these lines we actually will replace these are under headlines.

The lines from the tank up into the engine compartment.

We won't replace those generally will flush that would break cleaning compressed air to get gasoline.

But usually those holed up just fine.

But once we get to the fuel filter housing, we do replace the entire housing as well as the filter.

You can see there's valving inside of the filter housings.

We want to make sure we don't leave any gasoline inside of that as well as the rubber lines due to possible gasoline containing any problem with using brake cleaner through those those lines, you know, we're, not leaving it sitting there for any length of time, it's spray, very clean, and then compressed error rate.

So the fuel filter itself does this have to get replaced just comes as an assembly.

So we replace all of it it's got the filter been ok to it.

So from the fuel filter, we move on to the electronic pump.

What happens when you got gasoline in this with gasoline inside the electronic pump, it isn't able to have the lubricating properties like diesel fuel? Does so we go ahead and replace that not only you know, a lot of the stuff is we replaced.

It may not be let's say dead today, but we worry about long-term effects, right? So essentially what you're doing it when you put that gasoline is increasing the wear rate for that duration and decreasing the lubrication properties.

Yes, I.

These pumps, ok, that makes sense.

So from here, we travel to the high pressure pump right here.

We travel.

We go to the high pressure pump.

This is what jumps obviously, the fuel pressure up their driven by the timing belt.

This one did have metal contamination, what will generally do very first thing to do? This is a car that had the wrong fuel in it.

Yes, this is out of a car that had the wrong fuel in it as well as a technician that tried to cut apart.

I might be the technician.

So what happens with this you replace this? We absolutely replace this.

This is usually where the metal fragments come from it's, a failure of this pump internally.

And what we'll do is we'll pull this valve off the top of the pump.

And as you take the pump valve off, the pump you'll see embedded in the screen metal particles of metal particles coming from coming from this pump.

This point of failure and like all of the components in here, what what's what's wearing actually ever had a part in it could be bearing material cause remember we're not having anything to lubricate these parts like we do when we had diesel any of the components of metal-on-metal contact, your gonna be having more where because you don't have the lubrication for the diesel fuel.

And most of these actually do have to go back to the manufacturer.

So we are very fortunate to be able to have to pump sitting here on the bank, I'm pretty excited about having them near 22, ok.

So from the high pressure fuel pump.

We of course, go to the fuel rail, right? And what happens with this guy with the fuel rail is pieces of metal embedded into the rail.

Obviously, this is a closed unit.

We can't really get inside of it in see any type of damage.

So we go ahead and replace that as well and that's when cases done little coming here and let's, just gonna cause problems down the line, correct? Okay? And then from the shore, real, we move, of course to the fuel injectors, right and is that the same issue where you could have metal pieces.

You can come in here.

And so you want to replace these early on.

We actually weren't replacing the injectors and almost, yeah, you know, I actually, go rock climbing.

And so it gives me phenomenal grip strength and obviously, huge muscles where you can see what I had to do to this one to get it separated.

So if you can impress your teeth a little bit I did I.

Did yeah, we replace the injectors as well for the same reason, all of these parts you really need to think of in this way they may not be damaged today.

But the longevity of the part may be significantly reduced it to be fine for another 10,000 miles, right? Or you know, you could put it on the fragment sitting here and it's waiting to just destroyed and you're, waiting and waiting.

And finally, 10,000 miles later, it clogs it up.

And then you have other problems or its clubs open, which will make for somebody to have a really bad day loans wherever you are pumped eight hundred or so far through these high-pressure.

Yeah.

So it's, no joke, it's, not a joke it's.

Not a joke.

You shouldn't, put gasoline in your to give folks an idea, the catastrophic damage.

This really is if someone would have to pay for all of these parts you're, looking at about $1,000, repair $8,000.

And how much of that is parts, you know, it's it's about 4,000 and parts of 2,200 in labor, depending on the area of the country you're in the other thing.

You gotta remember is that when gasoline and diesel remix, there are special disposal processes that has to go through.

So that is actually super sounds like twenty-five, dollars a gallon to dispose of the team's.

All-Time curious obvious since I've, got four thousand dollars $1,000.

And generally this costs $1000.

Well, that's a lot of that is need fuel, expenses 25 bucks for a gallon.

What what happens when you have fourteen times 25 isn't 3,000 well, you know, I, don't match.

Anyways.

So it's about 800, you can do the math itself Jason, perhaps if we had a whiteboard or we could actually executed, you know, 4+1, I usually can do in my head.

But anyway, regardless to be $1,000 value.

You know, we can agree I think that is an incredibly expensive repair in these parts of actually come down a lot and it's, very simple thing to do to just put the rock.

I mean, it's, not necessarily Volkswagen tries to make it preventable, right? So that you don't put the wrong fuel in, but it's, very easy to put the wrong fuel in from a.

You know, it doesn't take a genius to figure it out, and you can very easily cost $1000.

And think of what happens if the truck killing at the station this fuels, the tank would have seen happen too.

So it can be any anywhere along the process can result in this viewing note in used to be this way.

The older diesel engines would actually run on gasoline around like crap, but they would run, and we would just pump pump pump gasoline output fuel filter in it and we'll be good to go.

But today, it's quite a bit of a repair.

So what you should take away from the video is that you should not put gasoline in your diesel car, which you probably knew beforehand, but we may or may not have known beforehand as the issuance subscribed to charles is channeled mechanic and I will, of course, have links all over the place that make it easy to do that one of the things that they might want to take away, but I'm, really well, you know, I work gloves cuz I was nervous about touching real parts, and we all have our strong points.

And we all have things like gray hair that kind of hold us back in my so guys watching.
