So, normal oil pressure in an engine, varies from one model to another.

Consequently, what’s normal for one engine, may be high or low for another.

Still, it is an important monitor of, how well the engine oil is protecting the moving parts of an engine.

Oil pressure will vary in most engines, depending on whether the engine, is cold or warm.

Also, the pressure will vary somewhat, with the speed the engine is turning. That’s why many vehicles, only have gauges that show, low, normal and high ranges. Furthermore, gauges that register, in (PSI), usually range from 0 to 100 (PSI). Consequently, the normal zone on these, is between 20 and 80 (PSI).

The gauge measures, the resistance to the oil, being pumped through the engine by the oil pump. The temperature of the oil, the type of oil and it’s viscosity, all affect that resistance. Consequently, the age of the engine affects the pressure, as well. New, tight engines will register, higher oil pressure, than older high mileage engines.

Low pressure indicates, insufficient lubrication, is being provided to the engine. A reading less than 20 (PSI) or under the normal range on the gauge, is cause for immediate attention. The problem could be as simple as, a low oil level. However, a high pressure reading, is uncommon. And, may just be a faulty gauge or an improperly functioning, oil by-pass valve.
