Jerry,
When I bought my car, it had 1600 miles on it and it was already running on Mobil 1
synthetic. I now have 4,000 miles on it and I changed it once myself at 2,500 (staying with Mobil 1). Is this a problem? My
oil pressure drops from around 60 PSI cold to around 40-50 PSI (depending on RPM) when it gets warmed up. Would you recommend I change it to a non-
synthetic?
I hate being stupid.
