The instant disclosure relates to a lubricant composition having an oil of lubricating viscosity, a polymeric surfactant compound that is an acylated polymer having a number average molecular weight of about 500 to about 50,000 where the polymer comprises a branched olefin having from 8 to 30 carbon atoms. The acylated polymer can further be reacted with an amine or alcohol to form an amide, imide, ester or combinations thereof. The present disclosure further relates to lubricant compositions that exhibit good dispersancy and viscometric performance.

Polymeric surfactant compound

The present invention relates to a tool for determining, improving and/or optimizing the change interval of a functional fluid utilized in a piece of equipment by using information on the piece of the equipment and its operating conditions. In particular, the present invention relates to the optimization of the oil drain interval of a vehicle by using a base change interval and optimizing it based on the operating conditions the vehicle experiences.
