In the old days before diesel was "winterized" it was SOP to add 10% gas to
your diesel tank, then fill with diesel (insures mixing). This was done to
prevent the diesel from "jelling".

RE: diesel in the gas
Maybe some of you remember but when I bought Sea Hawk the survey revealed that
the engine (diesel) wouldn't stay running. After the owner hired a mechanic
and had the HP pump replaced ($1800) I thought the problem had been licked and
departed on the 350mi delivery trip. About 20 min into the trip the engine
died AGAIN!
Long story short, about 2 months later I finally figured out that I had enough
gasoline in a 40 gallon diesel tank that I could run a 2 stroke weed eater off
the mix. When poured on a leaf pile it made quite a fire ball.
When the engine was cold, it would run fine but when it got warm the gasoline
would flash to vapor and lock up the HP pump. It acted like it lost prime. I
could keep it running with a priming bulb or by keeping it cool with a garden
hose.
Changed out the fuel and haven't had a problem since.
