Patent number: 11898119Abstract: A lubricating oil composition comprising greater than 50 wt. % of a base oil of lubricating viscosity, and an additive composition comprising: an amount of one or more zinc dialkyl dithiophosphates (ZDDP compounds) and an amount of one or more viscosity modifiers, wherein an amount of phosphorus (P) in weight percent provided to the lubricating oil composition by the one or more ZDDP compounds divided by the amount of the one or more viscosity modifiers (VM) in weight percent based on a total weight of the lubricating oil composition is a P/VM quotient of more than about 0.0075. The lubricating oil composition can improve resistance to engine deposits and extend oil drain intervals of an internal combustion engine.Type: GrantFiled: January 25, 2022Date of Patent: February 13, 2024Assignee: AFTON CHEMICAL CORPORATIONInventors: Todd Dvorak, Kenneth Garelick, Mark Devlin
