Benefits for multigraded oils developed for diesel engine service have been found in performance areas such as low temperature engine craking/starting, oil csonsumption rate, bearing wear, and fuel economy in stop-and-go service. Studies continue to indicate that multigraded diesel engine oils should be formulated with a minimum amount of pure polymer, consistent with desired viscometric targets, in order to minimize piston deposit formation. Premium multigraded, extended drain lubricants depend upon modern viscosity improver technology coupled with improved detergent-inhibitor additive technology.
