Top 10 Peak Motor Oils
for October 2022

Peak motor oil is specially formulated for high-performance engines, such as those found in cars, trucks, SUVs, and motorcycles. As the name indicates, peak motor oil is specially formulated to meet higher-octane requirements. While regular motor oil satisfies lower-octane requirements, peak motor oil can better protect your engine from damage when it's subjected to higher-octane fuel.

In the Different Guide , we have tested numerous brands of motor oil for performance, including viscosity, oil viscosity, oil oxidation, oil breakdown, oil oxidation, oil breakdown, and viscosity. We also evaluate oil for ease of use, such as how easy it is to pour, store, and clean up. Our top picks for peak motor oil are based on these tests.

Here are our picks for the top 10 peak motor oils:

The Valvoline full synthetic high mileage oil does what it claims. It reduced deposits, reduced engine wear, and lowered oil consumption, but the extra detergents and additives made it the most expensive oil we tested.
