no oil pressure at idle, 222K miles, advice?
Hi, I have a 2007 G35X, 222,000 miles, bought new. Oil changed properly the whole time.
It's now got about 7 psi of oil pressure at idle when hot. Pressure light is on. Goes away with rpm increase.
I took it to a mechanic who put a mechanical oil pressure gauge on the engine through the port where the oil pressure sender is attached.
He advises just drive it, put it in neutral at lights, air-conditioning off, it may last a while as I shop for a new car. He says its probably not even the pump but a combination of things most likely bearing clearances. Pretty much what I expected. I drained the oil and put in 10W-40 and still the same.
Anything else I should do? Any recommendations?
Thanks

I didn't have a mechanical oil pressure gauge, so took it to a trusted mechanic.

So he checked with a mechanical gauge?

Could also be the galley gaskets.
Check out this thread for some ideas on where to start. I highly doubt the mechanic installed a mechanical gauge but maybe he did? Definitely verify and if he did NOT then you probably should have an electric gauge and a new sender at minimum. Preferrably a mechanical.
