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.

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. So, Gauges that register in (PSI); usually range from 0 to 100. But, 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; 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. Finally, A high pressure reading is uncommon; and may be a faulty gauge; or an improperly functioning oil by-pass valve.
