OlRivrRat, thanks for the information. I do switch to the 40W for the hottest three months, and those are the months when I push the camper the hardest, also. I am following VW Vanagon owner's book recommendation. Forty weight for temperatures running at the high end of the nineties, 20W50 for lower than that. 20W50 does great in winter around here, and in spring and fall, also does well in northern states in summer. It is just too damned hot here and in the SW and interior areas of the west.
What do folks in Arizona do for running in summer? mcneely
