Vehicle owners or other users may obtain a motor vehicle engine oil having user desired enhancements, by using a wide area computer network, such as the Internet. In a preferred embodiment an electronic questionnaire is displayed on the user's computer screen, and the user answers inquiries about the environment of the use and desired operational characteristics of the desired oil, as well as information about the vehicle, ambient temperature, average driving distance, normal type of driving, and customer interest in fuel economy, cold weather starting, engine longevity and extended oil drain intervals and also to provide a centralized facility with information sufficient to determine what standard or customized motor oil would be most suitable for the user. A customized motor oil may be produced having a baseline motor oil from about 50 percent to 99.9 percent of the quality baseline oil with the remaining portion being customization additives. A desired property of the motor oil, for example, wear protection, fuel economy and the like could be varied by focusing on the desired percent change of the property desired, which might perhaps be 20%, or by changing the concentration of the oil additive to obtain such property.

Soot in a lubricated diesel engine is effectively dispersed without adversely affecting the viscosity of the lubricant by using a particular lubricant. The lubricant utilized comprises a lubricant base stock (e. g. more than 75% by weight), a dispersant (e. g. from 0. 2-less than 4% from a detergent inhibitor (D1) package), and a functionalized viscosity index improver (e. g. from 0. 1-2. 5% by solids weight). The functionalized viscosity index improver is a highly functionalized graft copolymer reaction product of an oxygen, a nitrogen, or an oxygen and nitrogen containing, ethylenically unsaturated, aliphatic or aromatic monomer having from 2 to about 50 carbon atoms grafted onto a polyolefin copolymer. Also, 0-2. 5% by solids weight of another viscosity index improver besides the highly functionalized graft copolymer reaction product may be added, as well as other conventional additives.
