What Psi should my oil be at during mid to heavy acceleration? I never noticed it before but I started hitting 90-120 psi. Does that sound right?

I'm running synthetic oil and recently have changed it with a new filter.

 

during hard acceleration in 3rd/4th I go to about 90psi. Usually never any higher when the car is warm.

@ 70mph in 6th gear I am at 60psi.

 

just as i thought. i know what I'll be doing tomorrow morning...

thanks for your help!

The only time I ever see 120 PSI is if I blip the throttle a little when the engine is stone cold in the morning.

If I saw 120 under moderate acceleration on a well warmed up motor, I would kinda start to freak a little.

 

The critical oil pressure occurs in extreme hot weather* at idle...........other than that 10 psi per 1000 rpm is enough.

Oil pressure varies with brand of oil and it's real instanteous viscosity [temp curve]
*coolant at 200F and oil sump at 220F.............afterall the bearings/under piston crowns are running 300-350F.

 

So, Q-Tech, in hot weather at idle, what oil pressure should you be concerned about? 10 psi? 5 psi? 0 psi (obviously...)
