Many modern cars require very thin (low viscosity) motor oil to operate more efficiently. Newer engines typically have tighter tolerances between engine parts. Let’s see if lower viscosity motor oil offers the same level of protection against engine wear. We’ll also see of the thinner oil experiences greater thermal breakdown and evaporation.
