Shell Rotella^® T6 5W-40 is a multigrade synthetic diesel oil that has a thinner viscosity for cold weather flow and startup. Formula helps to keep engines cleaner preventing corrosion and wear, resisting breakdown by heat to provide continuous protection throughout the service interval.

• Enhanced fuel economy capability of 1.5%* that can save money in fuel consumption, without compromising engine protection or durability. *Compared to 15W-40 oils.
• Significantly increased level of protection against harmful engine wear when compared to previous generation API CJ-4 synthetic engine oils.
• Resists viscosity loss and will maintain optimal pressure in your heavy duty diesel engine.
