Just wondering what some of you are getting for oil pressure? I bought my car and had good pressure then when I did the first oil change I switched to Mobil 1 synthetic and the pressure dropped to like 35 on start-up and then would get as low as 20 after driving for a while. Went back to regular oil and its back to 40-45 all the time.

I had a similar problem. When i first purchased my car the oil pressure was way low until i used mobile 1 and a k&n oil filter. Now at wot oil pressure gets well over 60. Cruising its around 45-50.

Mine was the opposite though. Good pressure with regular oil then dropped when i went to Mobil 1 syn.

I dont care for mobil it seem to be thin and burns faster than any other oils I've used, maby try some 10w 30 or somthing I recomend valvoline syn 10w 30 with a K/N oil filter I use it on all my cars now and after 3000 the oil is still cleen I've used it for several years, It may be a matter of preference but I think their are better quailty products out their that work better.
