Abstract: Lubricating compositions containing a phosphorus-containing salt of an acylated ethylene-a-olefin polymer substituted with an aliphatic polyamine having at least one primary or secondary amine, the lubricating composition having a total phosphorus content in an amount of 200 ppm to 600 ppm by weight of the lubricating composition. The phosphorus-containing salt additive described herein can be used as an anti-wear agent in lubricating composition for diesel engines.

Abstract: The disclosed technology provides lubricating compositions comprising an oil of lubricating viscosity, an alkaline earth metal sulfonate detergent having a metal ratio of at least 10, in an amount to contribute 3 to 14 g KOH/kg of TBN to the lubricating composition, an ashless, sulfur free, hydrocarbyl phenolic compound in an amount of 0.4 to about 6.0 weight percent (wt%) of the composition, and an ashless dispersant; wherein the lubricating composition has total ash of 0.3 to 1.8 wt%, total detergent soap of 0.1 to 1.2 wt% and wherein the lubricating composition contains less than 0.1 wt% of a sulfur-containing phenolic detergent. The disclosed technology further relates to a method of lubricating a mechanical device (such as an internal combustion engine) with the lubricating composition. The disclosed technology further relates to the use of the of the lubricating composition in a heavy duty diesel internal combustion engine to improve control of at least one of the following (i) fuel economy, (ii) corrosion, (iii) cleanliness, and (iv) bore wear.
