Diester Synthetic Lubricants For Automotive and Diesel Applications

New diester-type synthetic lubricants are being developed and tested for automotive and diesel applications. These new lubricants potentially offer fuel savings, extended oil drain intervals, longer engine life, cleaner engines, reduced down time, labor savings, easier winter starting, and faster warmup.

Standard passenger car engine sequence and extended sequence testing (SE) have been performed on the diester lubricants in an effort to substantiate long drain potential. Diesel testing has included Mack, General Motors, and Caterpillar engines. Field test data has been and is currently being generated for both passenger cars and diesels. Preliminary field data substantiates the long drain capability of synthetic lubricants based on diesters.
