What Do You Guys Use?

It's not just another oil tread in the F/I section. I asked because I have a F/I car. As I mentioned before, I ran M1 15w50 in my stock motor, but the new S52 has a stock bottom end, Schrick cams, and a Technica Motorsports-inspired turbo setup. 15w50 just seems a bit heavy for a motor with a bunch of new oil lines.

I ran 0w40 Mobil 1 in my ZHP, but this isn't exactly a ZHP haha

Only way to know if it "works" for certain is to try it, monitor oil psi and temp and then get an analysis done on used oil to check for wear deposits.

I use 0w40 Mobil 1 in my built and boosted S54 btw.

I was leaning toward the Mobil 1 for the sole fact that I love the 0 weight at startup. I never know what kind of weather I'm going to get here in Ohio.
