I have noticed every turboed engine that I have had, has had low oil PSI after it gets warm at idel. my Grand National, Eagle Talon, and this. its like 10PSI after it gets nice and warm and at idel. crusing its like 30-40 tho. Is this right?

What oil do you use? 10w40 hot on a hot day can even get to 10 on a higher mileage engine. Fresh enging? depends how tight, my last 2.2L ran 20psi warm w/ 10w40

I run between 30-40 psi warm with 10w30. It all depends on how fresh the engine is. Using a good gauge will also change your oil pressure reading!

10psi for every 1000 rpm.

Many factors involved, especially oil used. Mines 25 idle, 75 at 2500 rpm.
