I have xr6 turbo just installed oil pressure gauge what oil pressure should I be reading? I have been running 10w-40 nulon black 38% less friction, I started the car cold the other night it was about 60psi and started dropping after 5 minutes running it started dropping slowly done 56 then I turned it off I thought it was little high but not 100% sure what is everyone else getting

60 on a cold start is pretty normal and it will rise with the revs as you drive it.

If I remember rightly the minimums are when warm @2000rpm you should see no less than 43psi and warm @750rpm (idle) no less than 19psi.

Now I could be off by 1 or 2 psi but those numbers are familar.

I posted a thread about this a couple weeks ago man.

Mine is at just under 70psi at noise around 32 at idle and 50ish at cruise. I use penrite sin 10w50

0w - 40 in winter, 25 psi at idle 50psi at cruise and 65-70 psi at 5 - 6 k. 5w - 50 summer . 30 psi idle 55 - 60 cruise and 70 - 75 at 5 - 6 k. I have billet oil pump gears with a Nizpro modified housing.

Oil takes a fair while to come up to temp also

10w 40 for me. 60 at cold start. Heads south to 40-45 run time.

main thing is not being below min, or too high otherwise your engine wont be protected properly.

Yea that's sorta why im worried its brand new motor I did the atomic oil pump upgrade to it and head work so I don't want to be in the wrong range of pressure

Take it for a drive for half hour it'll drop as it warms up

Thanks guys for your help
