We have (as do lots of other DP's) a 150 gallon tank so it's not just trucks, A Blue Bird, Foretravel, Prevost or Newell will have 200 gallon or larger tanks.

Everyone knows that diesel pumps have red nozzles. ;>
That is why I read the words written on the labels instead.

Had a kid put gasoline in a GMC TopKick Fuel Miser Diesel. They got half a block before the engine blew. It was a total loss as they did a 100 gallon fill-up with gasoline on a 120 gallon diesel tank.

Having driven a diesel car (2005 VW Jetta) for the past 7 years, I wouldn't have thought twice about using a green pump for diesel fuel. I would absolutely had made this mistake as well if the shoe were on the other foot.

Glad it was something that was easily resolved, even if it did set you back a bit. Better to lose some time than the alternative...

Hmmm. Come to think of it, I too have seen this. I think I will put a can of red spray paint in the MH to help out these poor misguided stations.

Compare it to running 5 octane in a gasoline engine.

"Gasoline is formulated to resist auto-ignition in a spark engine, but gasoline introduced into a diesel engine will ignite at the wrong time causing severe detonation. Though diesel engine reciprocating components (pistons, wrist pins and connecting rods) are built to withstand enormous explosive force, the shock wave effects of uncontrolled detonation can easily destroy them."

I don't remember the formula, but in an extreme emergency, you can use gasoline and motor oil to power a diesel engine. I think it is something like 3 quarts of motor oil to a gallon of gasoline.

You can run about 10% motor oil:90% gasoline in a pinch. Now, this is speaking in terms of diesel engines built over the past 40 years or so, what the manufacturers are cooking up these days who knows but I'd be confident to follow that rule even then, if it were me. You take your own risks. If I were the OP, I would have poured in 10% as much motor oil (or more) than what I had pumped in of gas then topped it off with diesel and hit the road. There might be some effects on power and fuel economy but probably wouldn't have hurt anything. Whatever you do, don't use diesel fuel conditioner thinking that'll solve your problem, that'll only make matters worse. Even transmission fluid, power steering fluid or cooking oil will suffice in a pinch. Diesel engines are very resilient, you just want to make sure the fuel is oily like diesel, not dry like gasoline.
