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

Lower volatility in conjunction with detergents and dispersant used in Shell Rotella T6 15W-40 help provide 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.
