I believe that there is a Stabil Diesel version

Stored diesel will gum and create particulates. Both can stop the flow of fuel to the motor. See - http://www.catalina36.org/articles/recalls/dieselfuelstorage.pdf

If the engine you are feeding has a inline filter you’re ok (Having a spare or 2 is never a bad idea). If not, you’d want to filter it before putting it into the engine reservoir. I would think that TSC/Fleet Farm/Northern Tool would have one.
