All types of fuel go stale (yes, even diesel) with or with out additives. On seldom used gensets, the best way is to drain and or run the genset once in awhile. Or you can premix the old fuel with fresh fuel, but be ready to encounter misfires (palya) as the engine tries to burn the (mixed) contaminated fuel. As mentioned above, also try to use good fuel, and refrain using E10.
