Oil Pressure

[lachlan]

Hey i was just wondering if anyone could tell me what my oil pressure should sit on in my R33 GTS-T.

It will stay between 2kg/cm2 and 4kg/cm2 but as soon as i accelerate it rises to nearly 8kg/cm2. Should this happen or is something wrong?

yes it should. its just pumping more oil as then engine needs more when accelerating

that doesnt happen with me, when i start up the car from cold, its usually around 6 because the oil is thick and cool, then as the oil has warmed up it drops down to about 2-4 because the oil has warmed up and become thinner.

ive never heard before what you are saying, when you accelerate it goes up to 8.

what sort of oil are you using and when was your last oil change?

Im not sure what oil is in it, ive only just bought it all i know is its penrite oil the fully synthanic oil worth bout 75 buck a bottle, if its the wrong grade of oil could this cause the problem

How does the oil pump know if you are accelereting?

Oil pressure will increase with revs, and be higher when the engine is cold. It is not uncommon for pressure to go to the top of the gauge when cold if the revs are up a bit, although skyline gauges are notorious for being faulty/inaccurate

Not that you would be revving it when the oil is cold.

k thanks guys i just found it to be odd to be up so high considering this is happening around 2.5k to 3k revs, maybe the gauge my be faulty

between installing a hks oil pump and having the block arteries bored out the factory pressure gauge was pretty much useless before let alone after get a aftermarket one and T piece the oil pressure seder unit and hook it in there. even if the gauge lives in the engine bay somewhere atleast you have a accurate measurement.

My oil pressure range is always between 2 (idling) & 6 (accelerating) on the gauge.

BTW my car is dead stock (minus a CAT & turbo badge )

Well my revs go up when i use the accelerator ...

As stated...the factory oil pressure gauge is notorious for being inaccurate...get a proper gauge or learn to ignore it...mine has never read right since i bought the car...
