My oil pressure gauge seems to be decreasing a little bit gradually...
The needle always used to hang out beween the first and second mark, more twards the second mark... Now, cruising on the freeway, it sticks right on the first mark, and the highest it ever gets is halfway between the first and second mark...
Is there anything that can cause a gradual oil pressure decrease like that? Should I get a real pressure gauge, or is it just due to the 108 degree temperatures and I shouldn't worry about it?
The oil level is right a the op ofthe "safe" level...
