I put about 4.10 gallons of 85 octane gas in my tank before catching the mistake. After spending an hour trying to figure out how to get the gas out, I finally just said **** it. I just filled the rest of the tank with diesel fuel (36 gallons) and drove home. Should I be worried that there are 4 gallons of gasoline in the tank?

 

I wouldnt worry too much about 4 gal, Ive heard all kinds of stories about truckers adding unleaded to diesel in the winter to prevent gelling and people mix diesel, gas and motoroil to make something called "black diesel." I would throw some two-stroke oil in there for safe measures to counteract the gas but you should be fine as long as you arnt hot-rodding it or towing heavy.

 

Yeah. That seems like the general consensus. I drove about 60 miles today and the truck ran perfectly. You wouldn't even guess there's 4 gallons of gasoline in the tank unless I told you.

 

that is funny. my dads friend runs more gas through his Cummins than that. i would say if you pumped more than 10 gallons of gas in you might want to drain and dilute it more but 4 gallons is just funny.

 

let me guess you have no pyrometer as well?

If you did I would watch the pyro...it will probably run hot till all the gasoline is out of the tank. sometimes you will even see fire come out the tailpipe.

truckers used to add gas every once in a while to their tanks to "clean things out" basically makes the engine run very hot and a lot of times they would be putting fire out of the stacks from it. but it helps burn off the excess soot build up.
