Shell Rotella® T6 15W-40 Full Synthetic Heavy Duty Diesel Engine Oil is designed and formulated to provide improved performance compared to conventional and semi-synthetic Rotella 15W-40 products.
It is suitable for virtually all modern low-emission heavy duty engines* and older hard-working diesel engines. With its wide range of specifications and approvals from many of the world’s leading engine makers, it is an excellent choice for on-highway fleets, general haul, construction, agriculture, public-transport operators and diesel pick-up trucks.
Cold Climate Protection
Shell Rotella® T6 15W-40 provides better cold cranking properties and low temperature pumpability at -15C compared to conventional and synthetic blend Shell Rotella 15W-40 products. That means it reaches critical engine parts faster in colder temperatures to minimize wear and make hard work easier in cold climates.
Wear Protection Beyond CK-4 Standards
There are two basic types of wear in an engine: mechanical and corrosive wear, which is found when acids form during the combustion process. Part of an engine oil’s responsibility is to protect against wear. In API industry wear tests, Shell Rotella® T6 15W-40 didn’t just meet CK-4 specs, it demonstrated an 85% improvement in copper corrosion protection and 98% improvement in lead corrosion protection than required, an average of 50% more wear protection than required.
Delivers Excellent Oil Consumption Control
Shell Rotella® T6 15W-40 provides lower oil volatility in the Noack test compared to conventional Shell Rotella® T4 15W-40. Lower volatility = lower oil consumption.
