However, a general guideline is that you should see at least 10-20 PSI at idle (when the engine is warmed up) and 30-50 PSI at higher RPMs (around 2000-2500).
Crucially: The best way to know what's normal for *your* specific van is to consult your owner's manual. It will provide the specifications for your vehicle's year and model. The oil pressure gauge itself is also just an indicator, and its accuracy can vary. Low oil pressure indicated by the gauge warrants immediate attention.
If you're noticing significantly lower pressure than the general ranges above or inconsistent readings, it's advisable to have your vehicle inspected by a qualified mechanic to diagnose the issue. Low oil pressure can severely damage your engine.
