Performance FAQ

Can motor oil significantly improve horsepower?

Yes. Motor oil formulas with friction modifiers and additives help to improve horsepower. Lower viscosity (lighter) oils can improve horsepower providing that they separate moving parts and maintain engine durability. The optimum oil viscosity for a given engine is specified by the automotive manufacturer.

When motor oil is better for “severe” conditions, what are "severe" conditions?

Severe conditions include stop-and-go driving, consistent idling, pulling, towing, dusty environment or high or low ambient temperatures.

If I don't drive in severe conditions can I change my oil less often?

Your owner's manual may provide different oil change intervals for both regular driving and severe driving.

Is it a good idea to let your car warm up (idle)?

Most modern cars don’t require idling time before driving.

Can I improve motor oil performance in my vehicle by using aftermarket additives?

Generally no. Most vehicle manufacturers do not endorse using aftermarket additives. Certain additives may temporarily improve performance of older engines. (We recommend you check with the vehicle manufacturer before using any aftermarket additive.)

Are all additives the same?

No. Additives contain different formulations that affect certain parts of the engine differently than other additives.
