Larry,
How long should diesel last if the tank is topped up with no void for
condensation ?


Diesel lasts pretty well forever, it doesn't have nearly the volatiles
that gasoline has and it doesn't have alcohol in it to soak up water. I
have used ancient diesel without any problems and you can use it as fire
starter as well, or solvent, it's much safer stuff.

I had the same question last year since I have 500 gallons of diesel sitting
in a boat that has not been used for over a year. It's a good idea to add
some biocide (even a little water in the fuel will encourage critter growth)
but the fuel itself will last indefinitely. I have to check something
though .... I know gas fuel tanks on boats are vented, but I am not sure
about diesel tanks. I think they are .... which is another reason to add
some biocide from time to time.
