Torco's sr-4 fully synthesized machine oil was designed specifically for harsh working conditions. Sr-4 provides a high level of performance and protection for high performance engines using petrol, diesel and liquefied gas. Motorized engines are also recommended for alternative fuels. Sr-4 uses pao and ester base oil systems, which provide super-high-temperature lubrication and heat stabilization technologies. This combination of base oil and torco's excellent second generation mpz additive system minimizes friction losses and leads to more horsepower and recoil output. Sr-4 contains additional antioxidants and lubricants to eliminate drying from the use of alternative fuels such as e85 ethanol gasoline and liquefied gas. Sr-4 also provides high tbns and acids resulting from the use of diesel fuel containing high sulphur concentrations. Sr-4 provides unparalleled protection for critical parts of engines, including cylinder walls, pistons, rings, cam axes, gas doors and bearings。
