Today's diesel engines are more sophisticated than ever before. Design modifications that were made to increase performance and decrease emissions have forced more soot and contaminants back into the engine. The diesel engine oil must disperse these contaminants, keep them from forming harmful engine deposits while maintaining its viscosity and providing wear protection. This is no easy feat, which is why engine oil choice has become a critical decision for equipment and fleet managers.
