Well I finnaly got my new autometer guages in, one of which is oil pressure guage. According to it I am running over 50psi at idle cold, and about 45psi at idle when warmed up isnt this way too high? Can high oil pressure be caused by over filling the engine oil? Also Muscle Mustang ran a article a while back and they did a dyno on a stock mustang with only 4 qts of oil instead of the usual 5, and they netted about 10-15 HP because of the reduced windage basically. Is this a good idea? I have noticed a decrease in power after my last oil change in which my engine got overfilled by almost a qt. Which I would imagine is causing allot of windage in the crankcase and is robbing me of 20-30 HP? Can someone please answer my questions? thanks allot!
