Boxster S 3.2 engine oil pressures.

[VladD]

Does anyone know what the engine oil pressure should be for a 3.2 engine at both idle and under load?

Porsche doesn't give an idle oil pressure. Generally the hot idle oil presure wants to be high enough the low oil pressure light doesn't come on no matter how hot the engine/oil is. Roughly, call normal hot idle oil pressure 1 bar and above. (My Boxster doesn't have an oil pressure gage but my 2003 Turbo does and even when the engine is fully up to temperature after being driven around town on a hot day but not hot enough to require the A/C (which runs the fans and keeps the engine cooler) the hot oil pressure is below 2.0 bar, call it roughly 1.7 bar.)

For all 3 Boxster engines: 2.5l, 2.7l and 3.2l the oil pressure at 5K RPMs wants to be approx. 5 bar with the oil at 90C.

The above assume you are using an approved oil in the engine. Non-approved oils can result in different oil pressure readings.

Thanks very much.
