Molybdenum friction modifiers are commonly added to engine oils to reduce friction. The application of diamond-like carbon (DLC) coatings to engine parts to reduce friction is also being examined for improving fuel efficiency. However, molybdenum friction modifiers are not effective when used with DLC coatings. This paper describes a new 5W-30 GF-4 fuel-saving engine oil that has been developed with an ashless friction modifier for use with non-coated or DLC-coated valve lifters.
