Oil Pressure very high at start up.
Hi guys. I have recently discovered a new issue with my 2017 Mustang Ecoboost w/performance package and manual shift. Upon start up, specifically if car has been sitting for some time (hours), the oil pressure appears to be very high. According to Ford, in neutral at 2000 rpm, the oil pressure should be between 40-60 psi. However, in my case, in neutral at 2000 rpm my car is now between 90-100 psi (was between 80-95 psi when issue first started) until the engine warms up to normal, then the oil pressure is within the 40-60 psi. I do note that the oil pressure gauge maxes out at 100 psi.
I had the dealer look at it and even had the oil changed (again) along with filter. Dealer says car is not leaking, no dummy lights on, no warning lights on, and all other gauges are normal, thus the dealer says it is operating within normal specs. I am still concerned as this just started happening in the last 4 weeks or so. Has anyone else experienced this issue? Is this situation really normal? Based on my reading up on high oil pressure, I am concerned the engine will blow before it warms up. Am I concerned over nothing or do I really have a serious issue here?
