subaru wrx and t6. what is normal oil pressure?

[91camarosRS]

Just bought a gauge that is programmable for warning and whatnot.

What should my readings be with t6? What should i set my low pressure alarm at? Factory says this.

ALSO, what about temps? Ranges are as shown.. I want green to be 120-? Then yellow and red should be what. What should I do about high temp alarm? What should I set it at? Thanks!

If low is 14psi on 30wt I would say 15-20psi on 40wt should be fine as the low. Low pressure is more of a concern than high PSI in my experience monitoring my Honda motors, I have never got it hot enough to lose enough PSI to be in trouble at idle though.

On my oil psi gauge I have noticed around 5psi + or - on the min between weights at above avg temps, it does differ by brand between weights however.

There is about 2PSI difference, hot idle, between 5w-30 and 5w-40 on my Cherokee. Goes from 18 hot idle to 20 hot idle.

Obviously different engines and different vehicles, but not that much of a difference

I wouldn't set the warning any higher than 5 PSI. Yes, 12-15 may be the normal minimum you should expect, but there's no need to trip an annoying warning for random dips below that level.

Most factory lights come on around ~7psi...

The Subaru idiot light, meaning your engine is toast, comes on around 2 psi's.

12 psi

light should go back off once it gets higher. So I want it set to lowest amount that mymotor is not toast.
