Oil pressure Ive just done an oil change as the oil pressure was really low at idle, about half way between 0 and 2. now at idle (pic) it sits at 2. while running its on about 4 at temp. I'm running penrite 5-40 and done just under 5000kms Was thinking that: ive either got a dodgy sensor, the oil was buggered or oil pump is a bit flogged (changing at 100k service anyway) i now that the turbos kill the oil quicker as well, and also the gearbox (change oil in that too last month)was causing a bucket load of strain on the motor so im hoping its just my mind f$%king me over. suppose i can wait and see what i get on this oil change to tell the difference any thoughts ?????? As others have mentioned the gauge appears to be consistent with what is considered normal. The oil pressure will be highest when the engine is started from cold, as the oil temperature increases, the pressure will drop due to the oil becoming thinner. Heat will destroy oil, as will introduced contaminants, for example water & dirt. If you suspect an oil pressure issue, it is recommended to check the pressure using an accurate gauge. Severe & expen$ive engine damage will occur if the oil system is defective.
