It has been tested and proven to extend bearing life in high RPM/high horse-power drag race engines. It easily stands up to the high temperatures and longevity demands of stock car engines. When used in ordinary automotive applications, the user can expect up to three times longer oil life, high oil pressure, lower oil temperatures, longer engine life and lower overall maintenance cost.
The protective film of Lucas Racing 20/50 Plus assures a "wet" start every time, even after long periods of non-use. It is excellent for use in worn engines.
