Lucas Extreme Duty Marine Semi Synthetic 20W-50 Engine Oil is designed for use in high performance boats requiring the ultimate protection.

Lucas Extreme Duty Marine Semi Synthetic 20W-50 Engine Oil is manufactured with the highest quality paraffinic base oils and is fortified with an exclusive additive package containing high levels of Zinc, Moly and Phosphorus that provides a tougher, thicker additive film for maximum protection even under the most sever conditions. It lowers oil temperatures, extends oil life and minimizes metal fatigue.

Lucas Marine Semi Synthetic 20W-50 improves the film strength between the cylinder  wall and piston rings and slows oil burning while improving pressure levels in worn engines. It has good cold temperature properties and stands up to high operating temperatures. This product is compatible with methanol and all racing fuels.

FWRC Comparison of Lucas Oil

This is a report on the comparative testing between Lucas Products Synthetic 10/30 Plus Oil and other synthetic oils that FWRC has used in their oil pump dyno. The oil pump dyno is used by FWRC to test each and every oil pump we manufacture and repair for quality and integrity for applications including NASCAR, Open Wheel, NHRA, IHRA Off Road Racing and various other racing series.

The results of our testing have proven favorable to Lucas Oil.

The Lucas Synthetic 10/30 oil performed exceptionally well under high vacuum pump applications compared to other synthetic oils that FWRC has used. Test results were very consistent through various temperature ranges for several pump applications. The oil appears to be more stable as evidenced by less aeration compared to other oils that have been used.

As engine builders have recognized the benefits of negative crankcase pressure, aeration has become a major point if concern. When trying to maintain negative crankcase pressure the integrity of the oil and its resistance to separation is very critical and the Lucas oil performed well in these regards.

We at FWRC highly recommend the Lucas Synthetic 10/30 Plus oil for any high performance applications.
