(12 pack) (12 pack) Shell Rotella T6 Full Synthetic Diesel Motor Oil SAE 15W-40, 1-Gallon

"The viscosity grade that we know our customers prefer and trust*, now available in a full synthetic product. Shell Rotella T6 15W-40 Heavy Duty Engine Oil is a full synthetic product formulated for improved** hard-working protection. Shell Rotella T6 is suitable for new and older diesel-powered vehicles from Class 8 tractor/trailers to heavy duty pickups, delivery, utility and school bus fleets. It is suitable as a replacement for mineral and synthetic based SAE 15W-40 API CK-4, CJ-4 oils in low temperature applications. * According to Kline ** Compared to conventional and semi-synthetic Rotella 15W-40 products."

Strong oxidation resistance in the new Volvo T-13 test, controls harmful acid build up, and easily exceeds the API CK-4 limits for oxidation and viscosity increase. Improved oxidation resistance helps prevent deposits in the engine, maintain cleanliness, and prevent acid buildup, which can cause corrosive wear in the engine. Excellent oil consumption control, through lower oil volatility in the Noack test compared to conventional Shell Rotella T4 15W-40. Lower Volatility = Lower Oil Consumption. Improved copper corrosion protection and lead corrosion protection, with an average of 50% more wear protection than required by API industry wear tests. Better cold cranking properties and low temperature pumpability at -15ðC compared to conventional and semi-synthetic Shell Rotella 15W-40 products means that it reaches critical engine parts faster in colder temperatures, to minimize wear and make hard work easier in cold climates.
