I have a 2003 Saab 95 4 cylinder w/ 136000 miles. Previous owner always used Mobil 1. My manual says to use a Semi-Synthetic oil that meets: API - SH/CD/CF or SJ/CD/CF. ACEA A3/B3. Viscosity 5W-30 or 5W-40 semi-synthetic. I don't drive it hard and it usually gets driven about 5 miles minimum one way or highway driving at 60 mph. Engine runs great. I am considering putting in a performance chip level 1 to increase hp. Any thoughts?
Thanks, john
