farmer52 Posted May 15, 2014 Share Posted May 15, 2014 I may be biased, but I recommend Shell Rotella T 15W-40.

james j neiweem Posted May 15, 2014 Share Posted May 15, 2014 I mix 50/50 Shell Rotella dino and Shell T-6 synthetic. I read from a Shell petroleum engineer that these are totally compatable. Engine really cranks over fast in the winter.
