Is Royal Purple’s full synthetic 5W-30 motor better than Amsoil’s 100% synthetic 5W-30 motor oil?
In this motor oil showdown, Project Farm puts both products head to head in several tests. The three tests outlined in the video include tests for viscosity at varying temperatures, film strength, and evaporative testing.
In my opinion, the testing approaches used in this video provide consumers with valuable information on choosing the right motor oil for their specific application.
