Diesel in a Gasser

[benderado]

My buddy accidently put some diesel fuel in one of our gasser work trucks. It's an '05 3/4 ton chevy with the 6.0. When we were gettin' ready to leave at 6 this morning, it wouldn't start (surprise, surprise) and we had to tow it back to the yard so we could get another truck. The other mechanics at the shop drained the tank, filled it with gasoline, and it still wouldn't start.

We were wondering what diesel actualy does to a gas engine (i.e. burn out the rings, plug injectors, etc)?

I dont know, I have always heard it the other way!

If anything fowls out the plugs. Due to the diesel fuel having such a higher flash point then gasoline. It most likely soaked the plugs and fowled them out. I would replace the plugs with new ones. I would also change the fuel filter. Along with flush out the fuel lines and injectors with gas. That way the fuel system is not shooting any more diesel into the engine.

Then I would attempt to fire up the truck.

This is kinda reversed with what we see here. Usually it is oops I put gas in my diesel truck.

Okay, so how did someone even find a way to fit the nozzle into the fuel tank? Diesel fuel pump nozzles are larger than unleaded fuel nozzles, so that you are not supposed to be able to accidentally fill a gasoline-powered vehicle with diesel fuel.

Perhaps the station had the wrong size nozzle on the pump?

Back in the early days of unleaded fuel, they did the same thing so that you could not put leaded gasoline into an unleaded fuel tank.


Your work truck (the Chevy) will probably need (at the very least) new plugs, a new fuel filter and perhaps a good cleaning of the injectors.

Good luck with it!!

Not all diesel pumps have the big semi nozzle. The ones by me do not have the big nozzle. Unless you stop at a truck stop to fill up.

He filled it out of our tanks at work. They are right by each other and have exactly the same nozzle. The only way to tell the difference is the stickers on the tanks and the fact that the diesel one is covered in dust and grease.

I accidently put diesel in my sunfire once Didn't figure it out until half-way to work when it started sputtering (guess the diesel and gas didn't mix to well!). Anywho it was a cheap fix, only cost about $200 and then it was good to go. I can't remember everything they did, but I know for sure they had to clean out the fuel lines after draining the tank. So I would definitely recommend you do that

do as stated from above

I ran a mix of gas and diesel in my old jeep once cuz it was free. Didnt run to bad. Probably 70/30 gas to diesel. I worked with a guy that was a diesel tech. Bought a brand new F150 in 85 and ran a 60/40 mix or gas to diesel every tank for 200,000 miles. He did it just cuz he got it free. Didnt idle great but went down the road just fine!
