what could happen if diesel fuel was ran in a gas engine
(OP)
my boss had told me that a previous employee had filled up the tank of a delivery truck with diesel fuel instead of regular gasoline. the truck had a 1976 chevy 454 with a 4 barrel carb. it was driven for about 40-70 miles before anyone relized the problem. i was just wondering how much damage that could of done to that engine. the boss is afraid to take that truck out incase something is internaly wrong with it.
thanks
thanks

Not something Im proud of but I ran out of gas at a camp with a carbed truck of mine. All we had was kerosene and mixed-gas. 2 gallons of kerosene and a gallon of mixed gas and I was off to the gas station. Ran like a slug, but ran. That motor still runs fine. It just fouls plugs and carbons every thing up.

The difference in using gasoline and diesel is the self ignition temperatures. It is just opposite of what you would think it would be. High Cetane means it self ignites faster. Since gasoline is a low cetane it resists self ignition.

diesel is a fuel oil where as petrol is a spirit.
Diesel is used to lube the fuel pump where as petrol will strip the oil off of the bearings and seals in a diesel system. Thus the mechanical parts can be jiggered pretty quickly with petrol instead of diesel.
Been there and suffered. not my fault car in for service and garage filled it with petrol instead of diesel and it messed up the injection pump.

And you say diesel in a petro is okay, but gas in a diesel hurts???? All depends on the compression ratio. The CR in a diesel will have to be very high to self ignite gasoline. Since gasoline has a very low cetane. Especially the higher octane variety. It is a missconception that gasoline will explode in a diesel engine. It will knock do to ignition delay if the CR is too low.

effects.
I suffered - I had a garage fill the tank with petrol and then try to drive the car, it had a Fiat 1.9 turbo diesel engine built around 97-98 so before this modern direct injection JTD technology. The pump knackered up and the reason given was it had been contaminated with petrol.

Anyone who's ever received a single flight lesson will know that avgas is either green or blue, and jet fuel is clear or yellow.
Another fuel, combat MOGAS is red, but is for military use.
