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: 7207308Abstract: A crankcase lubricating system and method for lubricating an engine of a motor vehicle. The crankcase lubricating system includes filterless lubricant circulation system, and a crankcase lubricant containing a fully formulated lubricating base oil meeting or exceeding ILSAC GF-4 or API CI-4 minimum performance standards for engine oils.Type: GrantFiled: May 21, 2004Date of Patent: April 24, 2007Assignee: Afton Chemical CorporationInventors: David A Venhaus, Robert A.

Patent number: 6605654Abstract: A new composition, method, and apparatus for sealing and inflating a flat tire are described. The new composition includes a gas-generating agent and an activator, along with a sealant. In use, a gas propellant is generated in situ when the gas-generating agent is mixed with the activator. For example, carbon dioxide is generated when carbonates, such as baking soda, and an acid are mixed. The carbon dioxide gas generated in this manner can inflate a flat tire to a desired pressure. In addition to carbon dioxide, nitrogen gas, noble gases, and nitrous oxide gas may also be used instead.Type: GrantFiled: July 14, 2000Date of Patent: August 12, 2003Assignee: Pennzoil-Quaker State CompanyInventors: Jiafu Fang, Dewey P. Szemenyei, Troy H. Scriven

Patent number: 6510875Abstract: A new inflating device and method for inflating an inflatable object are described. The inflating device includes two compartments: one containing a gas-generating agent and the other containing an activating agent. When mixed, the gas-generating agent and the activating agent produces a gas in situ. The device further includes an activator connected to both compartments and is capable of effectuating mixing between the two agents upon activation. A hose assembly of the inflating device delivers a the gas generated to an inflatable object, such as a flat tire.Type: GrantFiled: December 15, 2000Date of Patent: January 28, 2003Assignee: PennzoilInventors: Jiafu Fang, Troy H. Scriven, Dewey P. Szemenyei

Patent number: 6353143Abstract: A fuel composition with a high flash point and a high octane number is provided. The preferred embodiment of the fuel comprises a paraffin or aromatic hydrocarbon component which may be mixed with an additive of alcohols, ethers, esters, organometallic compounds or mixtures thereof. The fuel composition is useful as emergency fuel for use in gasoline powered vehicles.Type: GrantFiled: October 28, 1999Date of Patent: March 5, 2002Assignee: Pennzoil-Quaker State CompanyInventors: Jiafu Fang, Dewey P.
