* At idle (around 600-800 RPM): Between 10 and 20 PSI. Some slight variation below 10 PSI at idle might be acceptable, especially if the engine is warm, but it warrants monitoring.
* At operating temperature and higher RPM (e.g., 2000 RPM): Between 30 and 50 PSI.
Crucially: These are *approximate* ranges. Your owner's manual will likely have the most accurate specifications for your specific vehicle. Always consult your owner's manual for the most reliable information.
Low oil pressure is a serious issue and can lead to catastrophic engine damage. If you're seeing consistently low oil pressure outside the acceptable ranges mentioned above, have your vehicle checked by a mechanic immediately. Possible causes include low oil level, worn-out oil pump, failing oil pressure sending unit (a faulty sensor), or more serious internal engine problems.
