SR-1R is a selective cross blend of highly advanced 100% synthetic base oils and proprietary additive systems aimed at increasing power, efficiency, and engine protection. The performance of SR-1R are uncompromised and designed using components over and above standardized passenger additive technology. Not compromised by price point, the SR-1's are purpose built specialty formulas designed to exceed the demands of high-performance European, Japanese, Korean, US, and other OEM's sports cars.

A combination of Generation-2 MPZ® and low friction base oils reduce frictional losses to increase horsepower and torque by as much as 3%. A premium polymer and additive system controls viscosity for long-term durability, maximum engine protection and eliminate engine deposits.

Torco SR-1 and SR-1R are the ultimate in high-performance synthetic motor oil technology. No other synthetic motor oil meets the performance and protection benefits of SR-1and SR-1R.
