We have all read so many threads about oil pressure at idle with the engine warm and everybody seems to fall into two groups. Some people have 5- 10 psi at idle and others have 15-20 psi at idle, I think we agree that the people with 5-10 psi are ok and that there is no problem with their car and oil pump, but how do you explain the difference in cars that are the same.

 

Different oil?

 

same reason some cars are lemons and some are beasts i geuss. None are going to be identical and alot matters on location and what type of fluid they use and a few other things could be a factor. So i mean it shouldnt matter to much unless it was causing a serious problem.

 

^^ Sensor location can have play a role in how the preasure reads as well

 

sensor location, as long as its consistent i dont worry to much
