Need to remove the oil sending unit that is on the back top right side of the engine and screew a oil pressure gauge in it's place, Then start engine and read oil pressure.
It should read no less then 6 PSI. at 1000 RPms.
At least 18 PSI at 2000 RPMs. more is okay too.
At least 24 PSI. at 4000 RPMs. more is okay too.
The oil pressure gauge will fluctuate on a Chevy Tahoe when the vehicle is idling and when the vehicle is driven at highway speed. Idle is usually 30 psi oil pressure or slightly more. At highway speed, the oil pressure should be between 60 psi and 80 psi.
40 on idle up to 60 while on the move.
Anything above 5 psi at idle will lubricate your engine. There is no maxim oil pressure for a 2003 Chevy Trailblazer. When the engine is cold and the oil is thick you should see 60 to 80 psi.
I have the same. If the engine is hot - the oil is thinner. Higher speed - higher oil pressure. Just check the level and on summer I'm using heavier oil.
Have a fuel pressure test done. A 4.3L should have 60 to 66 psi, a 2.2L should have 41 to 47 psi.
THE FUEL PRESSURE ON ALL CHEVY'S 95 AND UP IS 60 TO 65 PSI
I think around 40-60 psi maybe lower if engine has been running awhile!
normal oil pressure is 48 to 60
60 to 66 psi.
first test pressure with a professional test kit a mechanical one let engine reach operating temp. this will be you true pressure, sometime the electric oil pressure sending unit is not compatible with your gauge and give a inaccurate reading.your pressure is way to high,did you put a high pressure race pump in? if not you have a bad pressure regulator valve in your pump 60 psi is plenty to much will start blowing oil seals
The normal oil pressure for a 6.0L Chevy engine typically ranges from 30 to 60 psi when the engine is at operating temperature. At idle, it may be lower, around 10 to 20 psi, but should increase with RPMs. It's important to monitor the oil pressure, as significantly lower or higher readings can indicate potential engine issues. Always refer to the vehicle's service manual for specific guidelines.
