Today’s technologically advanced tractors and diesel pickup trucks require special motor oil.

Diesel engines operate with higher compression ratios, providing torque and power at much lower rpm’s than gasoline engines, thus making the diesel engine a much more desirable power source for higher load applications. Since diesel engines produce soot, which can be abrasive and prevent anti-wear additives from fully protecting critical engine parts, they require a motor oil with special dispersants, extra detergents and extra anti-wear components that are necessary to protect these engines.

Because of stricter emission requirements and changes in engine design, more soot goes into the oil in today's high-technology diesel engines. An oil with soot dispersing additives provides superior protection against engine wear, reducing deposits and viscosity thickening due to soot.

One example of this type of premium motor oil is Shell ROTELLA T Multigrade SAE 15W-40. In addition to its soot dispersing ability, Rotella T is specially formulated with an extremely shear-stable viscosity index improver, providing protection against viscosity loss and improving the ability to maintain oil pressure even under severe conditions.

Shell ROTELLA T meets or exceeds the warranty and service requirements of virtually all manufacturers, including Ford, Dodge, General Motors, plus Caterpiller, Cummins, Detroit Diesel, International, Mack, Volvo and Mercedes-Benz. For more information, visit: www.rotella.com.
