Regular gas in diesel?

Question

I have a customer that has a 2002 Chevy K2500 with the Duramax Diesel 6.6. He had a 1/4 tank and filled the rest with regular gas. He then drove about 10 miles and it died. I had it towed to my place and removed the tank to get all the gas out. I will finish the job tomorrow. I still have to reinstall the tank and replace the fuel filter. Before I did this I losened the bleeder valve and tried to start the truck and not fuel came out. The main question I have is that when I do all this should the truck start and run ok or do I need to do something else also.

Thank You

Answer 1

You should be good. Their might be a tiny bit of gas left in the system, but if you get the tank and filter changed, it should start after cranking a bit. Worst case scenario is that you have to disconnect the fuel lines at the cylinders and run a bit through. Had a similar problem with Bio Diesel fuel in a Sprinter. We pumped the tank and refilled. It took a few minutes to clear the lines and everything was fine.

Wow this is scary.
Gasoline burns much HOTTER than diesel.
Diesel fuel has lubricants in it that keep the pump from siezing up.
Gas has no lubricants.

I hope no internal engine damage was done, but the heat had to be in the critical zone before it quit.

With a little bit of luck the pump vapor locked or one of the pistons got tight before it scratched the cylinder.

If the gas can be removed from the lines you can try starting it once the tank has diesel in it. Be certain to get all of it out. You may have to prime the pump because the lines are full of air. Check with owners manual how to do that or call the dealer.

Before starting it I would check the oil. If the dipstick smells like gasoline, DO NOT TRY TO START IT. Drain the oil as it could combust and blow the oil pan clean off the engine. Maybe even start a fire.
Diesels are built very rugged so maybe she is alright.

I wish you the best of luck. (Your friend too).

On a diesel engine you will have to prime the fuel pump before it will start make sure you hook up a battery charger to the truck because it takes alot of cranking to prime the pump! You also may have to push and hold a valve or a button on that model im not to sure. Call the dealer and ask the service Mgr if it wont start.

Answer 4

when you get the vehicle ready to start, you will need to bleed each line to the injector. You got to get that air out of the system. The customer is lucky that he still has a engine. Just hope that he has not done any damage to the fuel pump from using gasoline. If it is damaged, tell your customer that he is gonna have to fork out about $2000 or better for a new fuel pump.

Answer 5

If the engine was ran for 10 miles, then the engine is probably destroyed internally. You will have to replace the engine. Your best bet is to consult with a diesel mechanic. Good luck.

Years ago, my husband told me to "go gas up the tractor," didn't tell me to "go diesel up the tractor." It died in the middle of the field...a mechanic came, drained the tank...got all the gas out of the system and it ran fine. As long as you get all the gas out of the system, it should work fine.

Answer 7

I would think that it would run o.k. but then I am not a mechanic.
If you are not a professional mechanic then I would contact a reputable garage mechanic first. Wouldn't want to make it worse.
Actually it wouldn't be a bad idea to contact the Chevy dealer first.

if just run for little while and didnt get to hot everything should be fine we use to add gas to diesel in winter to keep from gelling up
