Today’s gasoline engines require a higher level of performance and far greater protection from the oil, due to engine manufacturers continually working to improve fuel economy and reduce emissions with design changes.  PRO-SPEC SYNTHETIC MOTOR OIL is licensed to meet both the American Petroleum Institute’s (API) SQ specification and the International Lubricants Standardization and Approval Committee’s (ILSAC) latest GF-7 specification.

PRO-SPEC SYNTHETIC MOTOR OIL currently exceeds the parameters in all engine tests needed to achieve the GF-7 and SQ specifications.  PRO-SPEC SYNTHETIC MOTOR OIL is formulated with a detergent package that keeps your engine clean from piston deposit build-ups and neutralizes acids but does so without increasing the frequency of LSPI.  In addition, testing shows the chemistry of PRO-SPEC SYNTHETIC MOTOR OIL can provide up to 20% better fuel economy!

Whether you have a brand-new gasoline passenger vehicle or an older model, PRO-SPEC SYNTHETIC MOTOR OIL will provide superior protection you can count on.  Testing was done in cab and transit services under severe temperatures and conditions, and the engine main bearings and cams remained clean at the end of the extensive ten-thousand-mile drain interval.
