[QUOTE="YELOSNK, post: 16665314, member: 30747"] I've seen folks state both 80w90 and 75w140. Which is the best choice? If it matters, I have 4.56s and this car is solely for backroads bashing with (hopefully) a few track days per year sprinkled in going forward. And past that, any reason to pick one or the other between RP, Amsoil, and Red Line? [/QUOTE]
