Thanks for the reply, here in Portland, we seldom get to 0 degress (thankfully), but since I put a ton of miles on my Passat diesel and some on my cummins, the 2 cycle oil lube has been intriguing me. My local Bosch dealer says to add anything I like to the fuel, just add something to help lube. Was worried about the effects of the solvent in the 2 cycle oil. Or maybe that was the old 2-cycle oil. Thanks again. Tim
