Your_Evil_Twin96 Posted January 11, 2015 Report Share Posted January 11, 2015 Just bought bone stock ss from father with 133,000 miles. He has always had regular oil in engine but I wanted to use full synthetic and bought Mobil one. I didn't notice the oil pressure gauge before oil change but dad said reads 40ish at idle. But now as soon as startup the gauge goes to 80 and never drops. Is this normal for ffull synthetic or is the oil pressure sensor bad maybe? Any help would be appreciated guys,thnx Quote Link to comment Share on other sites More sharing options...
