Shell Rotella T6 5W-40 diesel engine oil is a full synthetic motor oil that features exclusive Triple Protection Plus technology. It's formulated with fully synthetic base oils plus advanced additives to protect against wear, deposits, and oil breakdown. It also provides better low-temperature flow and enhanced fuel economy performance of 1.5% (compared to 15W-40 oils). Shell Rotella T6 5W-40 is suitable for new and older diesel-powered vehicles from Class 8 tractor/trailers to heavy-duty diesel pickups, delivery, utility, school bus fleets, and motorcycles. It provides a significantly increased level of protection against harmful engine wear (compared to previous generation API CJ-4 engine oils), and the advanced multi-functional dispersant additives offer an enhanced level of protection against the effects of soot, dirt, and other contaminants.
