The demand for improved fuel economy is placing increasing pressure upon engine manufacturers world-wide. Lubricants that can provide additional fuel efficiency benefits are being vigorously sought. Such lubricants must achieve the current performance specifications that are also increasing in severity. To meet all of these requirements, passenger car lubricant formulations will need special base oils. This paper presents data on comparable 5W-30 formulations based on either hydrogenated mineral oil, or hydrocracked or poly alpha olefin basestocks. These blends clearly demonstrate the effect of improved volatility on oil consumption and oxidation stability in a range of bench engine tests. Equivalent engine test performance is observed for the hydrocracked and polyalphaolefin blends. Both exhibit performance superior to that attained by the hydrogenated mineral oil-based blend. Predict Sequence VI fuel savings for these blends show additional fuel efficiency benefits for hydrocracked vs. hydrogenated mineral oil-based blends.
