no check the oil when the engine is at operating temp

use the dipstick and check the level of oil in the engine

ok if you dont see the warning light at post diag then it could be dead

so you could in fact have low oil pressure under load

when you say it drops - what rpm does it drop to 2 at?

When iam on full boost so the car is around 5 to 6rpm the gauge will drop and the gauge will read around 2 on the pressure gauge.

Just then i warmed the car up, the dip stick read about half way so might just be low oil,

Ok dont laugh people like 2days ago i tryed to change my oil i coundnt get the built off the sump .

From the engine manual (for RB26): at operating temp your oil pressure should be approximately:

1.5 kg/cm2 @ 800rpm

3 kg/cm2 @ 2000rpm

4.6 kg/cm2 @ 6000rpm

you should just call my uncle tomorrow and rack his brain

Peter - Mobil Lubeline 1800 033 863

From memory, and from memory of Peter talking at the SAU meeting.. the higher the letter (ie SG), the more recent the oil/newer standard etc. So SE was released in like 1979, SF is from 1980 or thereabouts. So SG is better protection and what not...

I just did a oil change today i used 300v chrono motul, the oil type is SL is that a bad thing its not even listed on the chart? and how many leters of oil should you use in a RB26?

And do i need to drop all the oil out of my catch can because i changed oil brands, the reson iam asking the oils will mix can this be trouble.

its good oil.. but too expensive.. i use royal purple

when my old engine shat itsself i used to nail it all the way to the limiter and it used to sit DEAD ON ZERO once i planted it..

Well i change the oil and now when i stick it the pressure gauge jumps between 2 and 4 i rekkin it might be the gauge because its goes all jerky. i know this got nuffin do with the pressure, but even the light for the gauge plays up one minute its on the next it turns off by it self.
