Method for improving the fuel efficiency of engine oil compositions for large low and medium speed engines by reducing the traction coefficient |
摘要 |
The present invention is directed to a method for improving the fuel efficiency of engine oil compositions by reducing the traction coefficient of the oil by formulating the oil using a blend of one or more first base stock(s) selected from Group II base stock, Group III base stock and Group IV base stock and a second base stock selected from polyisobutylene (PIB) and, preferably, additized with a detergent. |
