What is the normal operating range for the oil pressure gauge?

The normal operating range for the oil pressure gauge is crucial for assessing the health of the engine and ensuring that it functions effectively. An oil pressure gauge that operates within the range of 90-120 psi indicates that the oil is circulating properly throughout the engine, lubricating its components and preventing wear and tear. This range provides an optimal balance that supports engine performance while maintaining safety and longevity.

Operating outside of this range can lead to either too much or too little oil pressure, both of which can cause significant engine damage. Therefore, recognizing and understanding the correct range helps in diagnosing potential issues early and ensuring the engine remains in good working order.
