Engine oils.

I've seen the psi list before and don't know how it actually compares to how well an oil works in any particular engine....but it is interesting info.

At this point, our motors have been rebuilt and have different clearances than factory so you could get away with different weight oils depending on your engine. Kendall is a good oil. I tend to stick with a 10w30 or 10w40 depending what is available or on sale, with zddp as both my Mopars have solid lifter cams.
