Engine Life

The primary purpose of engine oil is to stop metal from touching metal. When metal surfaces come in contact, they grind together causing friction. That creates heat, stress and wear. Engine oil is used to reduce friction by creating a slick film between metal parts that allows them to glide over one another. Consequently, engine longevity begins with choosing the appropriate engine oil that is right for the engine and operating conditions.

An oil’s viscosity (a measure of its resistance to flow), along with the pressure and speed of movement, determines the thickness of the oil film between two moving surfaces. This, in turn, determines the ability of the oil film to keep the surfaces apart, the rate heat is generated by {continued…}
