Gas in diesel in 7.3

So I get a call this morning from one of my guys telling me he put some gas in the truck on accident. After finding out that he added 13 gallons to an empty tank I told him to fill the rest of the truck with diesel add two quarts of ATF and baby the truck back to the lot. I was going to keep running the truck till 3/4 of a tank and topping it off for a while than changing the fuel filter in a 3-4 weeks. Just wondering if this is ok...I really can't afford to blow the motor in this truck as the only work I have this time of the year is plowing and we've only had two good storms this year. Any help would really be appreciated thanks guys

That is a lot of gas to try to dilute. If it were me I would drain the tank and refill with diesel assuming that he has not drove it yet.

As much as these engines cost and if you rely on it for work then dont risk it.

1/2 a Tank of GASOLINE!!!!

No WAY you should try to run that through the engine....

Drain that tank or you'll pay for it later.

Well I have a 55gal drum that I usually keep bulk oil in for the trucks that is now empty so what about emptying the whole tank into that and filling the last 25 gallons or so with straight diesel and adding 5 gallons every fillup. I really don't want to throw 90 worth of fuel away if I don't have too

The problem is that the gas, going through the injectors where fuel is relied on for lubrication, even WITH some additional additives, is going to do damage.

Sure, you could use it up more slowly, but what you're taking about here is like putting a couple of gallons of gas in every tank for some time.... That doesn't sound like a good idea to me

You know the 7.3 wasn't designed to run on ULSD so, without adding something like Opti-Lube with every tank you're already prematurely wearing everything the designers used the fuel to lubricate with the old diesel. Gas just sounds like a recipe for disaster

I'd burn it with my heating oil before I put it back in my truck!

I agree. DON'T TRY TO RUN IT. I saw a 6.4 that had a 25% mix of gas in the diesel and it trashed the high pressure fuel pump and all 8 injectors. I know that the 6.4 has a different fuel system, but it's not worth having to buy a set of injectors or melting a piston or two.

Bonfire starter. I'm not even sure that I would trust it in a torpedo heater.
