higher viscosity oil has its place in a turbocharged engine..i dont remember exactly what the deal is, its in corky's book i know.
Doesn't it have something to do with the turbo seals, and the life of your turbo. Lower viscosity has a better chance of getting past the seals, but it could be more complex than that.
Anyway...Mobil 1 10w-30
