Our MPT Thirty-K Motor Oils for passenger cars, as well as our Motorcycle and Racing motor oils, are manufactured with the highest percentage of ester base stocks in the industry. In fact, most are blended with 3 different esters to help achieve the proper viscosity and provide the best high temperature operation possible.
We blend the esters with polyalphaolefin and robust additive packages to provide outstanding performance.
We also eliminate the use of viscosity modifiers and Group III petroleum base stocks which are advertised as synthetic by our competitors. This enables competitors to keep down costs, but results in greater oil evaporation loss and volatility during high temperature operation.
