    Yes and no. It depends on the mix. a 50/50 mix should work ok. But 100% biodiesel will like act as a cleaner in the system and may plug filters. In that case if possible, I would recommend getting a few extra fuel filters.

    I'd add that IF it's 100% biodiesel he may also have trouble starting the genny up in cold weather. Keep some reg diesel around for starts and also shut-down on the regular. Once running the heat from genny should be plenty to keep it from gelling.

    Bio Diesel acts like a solvent or a "soap" to regular diesel. If you suddenly switch to biodiesel on an existing diesel unit, it will break all the crap loose from the existing fuel system and plug filters for awhile. Once all the crap gets cleaned out, it will run fine. As noted the "pour" point of biodiesel can be higher than regular diesel so if the fuel gets much below 50 degrees you need to warm it up or blend it. There are additives to reduce the pour point. I beleive the oil companies just blend in kerosene to redcue the pour point of regular diesel.

    Blending 10% methanol will eliminate many problems as well.
