• Better fuel economy - compared to 15W-40 oils Rotella offers enhanced fuel economy capability of 1.5% without compromising engine protection or durability.
• Improved wear performance - provides a significantly increased level of protection against harmful engine wear when compared to previous generation API CJ-4 engine oils.
• Improved deposit control - advanced multi-functional dispersant additives in combination with synthetic base oils provide an enhanced level of protection against the effects of soot, dirt and other contaminants.
• Emissions system compatibility - advanced low-ash formulation helps control blocking of or poisoning of exhaust after- devices, helping maintain vehicle emission compliance and engine fuel efficiency.
• Improved heat resistance - resists breakdown by heat to provide continuous protection throughout the service interval.
