Abstract
Non-thixotropic, sodium-free lubricant additive having from 10% to 50% of a liquid organic diluent and from 30% to 90% of a substituted hydrocarbaryl metal salt. At least 30 mole percent of the metal in the metal salt is lithium, and the salt is essentially free of sodium. The BN of the non-thixotropic lubricant additive attributable to the lithium is less than 150. This additive is useful for decreasing black sludge deposits and piston deposits.
