I run it in my bike with no issues (10w40 recommended). However, I do wonder if it might be a bit on the thick side when at operating temps in the car. If you live in real hot climates (az, nm, etc) then it might not be a bad idea.
Anyone done a UOA on a 5w30 oil in these climates and then compare to a 10w40 or 5w40?
