valvoline 5w30 full synthetic in the mustang, and valvoline maxlife 10w30 in the ranger.(can you tell i sell valvoline at my store, lol)
and most companies are beginning to switch back from 5w20 to 5w30 now, dont know why, but its only been a couple years that 5w20s been widely used and i guess maybe they are beginning to see problems already, most hondas are back to 5w30s and some fords. id stick with 5w30 personally.

Im a strong advocate for M1, but have been thinking about making a change to something else. My rule of thumb for the smurf is to use 1qt for every thousand RPM I spin. (shift at 6500, so I run 6.5quarts)
