Patent number: 8977421Abstract: A system, a method and a computer program to determine the usability of a lubricant such as, e.g., engine oil, and when to replace the lubricant in a particular engine. The system, method, and computer program are further configured to generate a lubricant discard interval for each engine in, e.g., a company's fleet of vehicles. The system, method, and computer program are configured to generate lubricant discard interval schedule for each of the vehicles in the company's fleet based on the lubricant discard intervals.Type: GrantFiled: July 31, 2014Date of Patent: March 10, 2015Assignee: Afton Chemical CorporationInventors: Todd M. Dvorak, Robert T. Dittmeier, Dewey P. Szemenyei

Patent number: 8965625Abstract: A system, a method and a computer program to predict a portion of used lubricant in an engine that is to be drained and replaced by fresh lubricant based on an analysis parameter value that is measured in a sample of used engine lubricant from the engine. The system includes a first input that receives the analysis parameter value from the used lubricant and stores the analysis parameter value in a memory of a processor. A second input receives an analysis parameter threshold value for the used lubricant at the end of a service interval and stores the analysis parameter threshold value in a memory of the processor. A determiner predicts a future analysis parameter value of the used lubricant at the end of the service interval based on the analysis parameter value, and the analysis parameter threshold value.Type: GrantFiled: July 31, 2014Date of Patent: February 24, 2015Assignee: Afton Chemical CorporationInventors: Todd M.

Patent number: 7863228Abstract: A multi-functional composition for use as an additive for fuels and lubricants. The composition includes an amination product of a hydrocarbyl substituted succinic acylating agent and a mixture containing an aliphatic polyamine and an aromatic polyamine. The molar ratio of aliphatic polyamine to aromatic polyamine in the mixture ranges from about 10:0.1 to about 0.1:10. The amination product contains at least about 0.1 molar equivalent of the polyamine mixture to 1 molar equivalent of the hydrocarbyl substituted succinic acylating agent.Type: GrantFiled: March 17, 2008Date of Patent: January 4, 2011Assignee: Afton Chemical CorporationInventors: John T. Loper, Paul G. Griffin, David A. Hutchison, Robert T. Dittmeier
