General rule of thumb......10 p.s.i. for every 1000 RPM
The normal oil pressure on a GM 305 engine is between 40 and 60 PSI depending on the model year. High oil pressure is needed to allow for proper circulation through the engine.
Mine had about 80-110 psi
16 #
2
1,000 psi
5W30 oil is factory, Gastrol GTX is a real good oil to use.
40 to 47 PSI
9 to 13 LBS. ( PSI )
this is normal, when the car is cold or off. the oil sinks down in to the oil pan.,. If this is a GM engine you may be using an aftermarket oil filter that allows oil to drain back this is not a good thing and can cause engine damage. GM has a TSB on this very problem.
c5 corvette has bad sending units[ engineer world its called a transducer], $600 to replace since the intake manifold has to be R & R ALSO, when cold the Oil pressure will be in the 70 psi range then when hot, on a stock c5 this happens quickly because GM designed the car to run hot to paSS EMMISSIONS, IT WILL DROP TO APPROX 20 PSI. Normal operationg oil pressure for a 1999 corvette should be anywhere for 50 to 60 psi depending on oil one is using.
Where is the oil filter on a GM 2.2 (2004 Chevy Malibu classic) and how do you change it?
About 14 gm of oil in 1 tablespoon. 110 gm is 7.857 tablespoons.
