Motor Oil Info

Oil viscosity is a very important factor when determining oil’s ability to absorb and transfer heat away from critical engine components. First, given two different viscosity levels, it takes more energy to pump the oil around the lubrication system with a thicker oil because it provides more resistance to flow and will build up heat faster than a thin oil being pumped through a restricted area.

If oil is too viscous and difficult to pump through the system, the ability for the oil to get to the critical engine components may be compromised creating more friction and heat build-up. The opposite can also take place if the oil is too thin for the application. In this case there may be an insufficient layer of lubricant to protect the metal components and the result is more friction and heat build-up. The bottom line is to make sure to use the correct viscosity for the application. We recommend AMSOIL Synthetic Motor Oils due to its high film strengh and resistance to breakdown.
