Recently my rb25 has a oil light come on after the car warms up to idle I get a low oil light that comes on. Anything over 1000rpms it's goes away. I do not have a gauge to check bit I did a test at idle and I'm only getting 10-12 psi very low. From wat I was looking at its has to be over 20psi. I also sent an oil sample out to make sure nothing wrong internally. I no that rb25 oil pumps are know to go. Anyone with knowledge or a suggestion message me thanks .
Get a gauge hooked up before you presume anything.
Pretty sure idle pressure with warm oil would be within spec at 10-12 psi, it is on SR's, get a gauge.

I need to get a gauge we have one hooked up at idle but nothing to see when driving and it's Normal for it to be that low could it be a bad sensor?
I had a R32 with a rb20, same symptoms as you, I was unlucky and the pump was toast.
Yes it could be a sensor gone bad, get a gauge and go from there.

Don't assume anything. get a gauge, check your pressure after car is fully warmed up then go from there.
