Recommended for stock, tuned or modified street, light truck and sport vehicles where an SAE 5W-30 is specified. Provides exceptional cold temperature performance over conventional (petroleum) motor oils within the same viscosity grade.  Features & Benefits  - 100% Synthetic Formula  - Generation-2 MPZ frictional loss technology - Increases horsepower & torque  - Reduces operating temperatures - Advanced engine protection  Exceeds: API SM/CF, ILSAC GF-4, ACEA C3-04, ACEA A3/B3/B4-04, MB 229.31, VW 502.00/505.00, BMW Long Life ?– 04  SR-1 is a selective cross blend of highly advanced 100% synthetic base oils and proprietary additives aimed at power, fuel efficiency, and engine protection. SR-1's performance is not compromised by standardized additive technology or by our competitors' price points, it is simply a purpose built, specialty formula designed to exceed the demands of high performance Japanese, European and US 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 is the ultimate in high performance synthetic motor oil technology. No other synthetic motor oil meets the performance and protection benefits of SR-1.
