Will a high volume oil pump increase oil pressure?
According to Osterhaus, “the increased internal clearances found in a high-mileage engine create a higher demand for oil. A high-volume pump will provide assistance in increasing the oil flow to fill the larger internal clearances. This results in increasing the oil pressure.

What is the advantage of a high volume oil pump?
A High-Volume Pump will push more oil through the system. It has larger gears to move more oil per revolution. These pumps are good for performance engines with larger bearing clearances. The added oil will help maintain oil pressure and carry away heat.
What is considered high oil pressure?
A PSI over 80 is usually considered too high for the engine to properly be protected from damage. High oil pressure is an indicator that the oil is not able to properly pass through the bores and reach all parts of the engine effectively.
How high is too high oil pressure?
What’s normal oil pressure at idle?
