Thanks Mathieu, I'll look into that one too. Looks like I'm going to do some serious reading up soon. I was using regular Valvoline 20/50 years ago in my 911, but I could never seem to get it to burn off condensation, and it would form "honey" in the oil. I switched to Q State because of that, and the problem went away. Valvoline is what my dealer was using at the time. I'll look into the VR1 racing oils.
