PROTECTION AGAINST WEAR
Shell Rotella® T6 delivers 34% better wear performance on average compared to the previous API CI-4 PLUS 5W-40 formulation. In seven out of seven industry-standard, diesel-engine wear test measurements, Shell Rotella® T6 outperformed the previous formulation. LOW EMISSIONS   Protecting the performance of your exhaust-emissions control systems is not only important for your vehicles to comply with legislative requirements, but also to promote efficient operations. For instance, blocked diesel particulate filters (DPF) can actually increase fuel consumption. Shell Rotella® T6 is formulated with reduced levels of ash, phosphorous and sulfur to help maintain the efficiency of the latest vehicle-emissions technologies. Meeting the ash, phosphorous and sulfur requirements of API CJ-4, Shell Rotella® T6 has been tested and proven to protect your vehicle.
IMPROVED HIGH/LOW-TEMPERATURE PROTECTION

 Shell Rotella® T6 provides extra protection against breakdown by heat and offers up to 70% better oxidation resistance, compared to conventional Shell Rotella® T3 15W-40 API CJ-4 oil. Shell Rotella® T6 5W-40 provides excellent low-temperature flow, even at -30ºF. MAINTENANCE SAVINGS

At lower temperatures, using Shell Rotella® T6 5W-40 can help your engine start more easily than using a 15W-40 viscosity- grade product.
Shell Rotella® T6 5W-40 can help protect the durability of the starter and battery in harsh winter climates.

Shell Rotella® T6 5W-40 provides unsurpassed protection against shear-stability degradation, compared to the leading competitive API CJ-4 5W-40 products. An extremely shear-stable product helps maintain consistent viscosity and oil pressure in the engine.
YOUR PROTECTION - OUR EXPERIENCE

Shell Rotella® T6 has special molecules that resist compression to keep moving parts separated, reducing wear. The antiwear booster provides extra protection against wear in highly stressed areas
of the engine.
PROTECTION AGAINST SOOT

Shell Rotella® T6 helps control the impact of soot on your engine through increased levels of high-performance ashless chemistry that keeps soot particles apart — up to 36% improvement in soot control at typical engine-oil-soot levels.* This helps keep the oil free flowing for good startup and continued energy efficiency, and helps prevent sludge, deposits and wear. *Compared to Shell Rotella® T Triple Protection® 15W-40 at typical end-of-drain soot levels, based on MACK T-11 soot-test analysis.
