It is no secret that without the proper amount of Zinc Dialkyl Dithio Phospate (ZDDP), flat tappet camshafts in race engines can experience problems. The simple solution to that issue is to use the proper oil or additive as part of your racing program.
Oil City, Pennsylvania, based Les Frickshun offers two products racers of all classes will find exceptionally valuable in maximizing their performance. Les Frickshun Synthetic Blend Racing Oil is specially formulated to meet the rigorous demands found in high-performance race engines, including having the right amount of ZDDP to ensure proper flat tappet operation. Using premium products blended with superior synthetic oil and conventional mineral oils, its formulation has been used in World Class engines in the IMSA endurance races with outstanding results. A top quality synthetic blend SAE 20W-50 motor oil meeting API SJ specifications is boosted with additional anti-wear and detergent additives to provide top-level protection for high-performance engines. Their racing oil is available in several viscosities as well as a straight mineral base, synthetic blend, and full synthetic versions.
In addition to their line of racing oils, Les Frickshun also offers ZINC a ZDDP additive that is available in two package sizes. Pro Pac will take an API SM motor oil up to 2,700 ppm of zinc while the Consumer Pac will take SM oil to 1,500 ppm of zinc. Most cam manufacturers recommend this range of ZDDP level to ensure proper flat tappet operation.
Les Frickshun has taken the ease of using their additive a step further. By formulating their zinc additive with a special carrier all you have to do is replace one quart of oil in a typical five quart oil change with a quart of Les Frickshun ZINC. The Consumer Pac is designed for street performance applications while the Pro Pac is designed for all out race applications.
Compatible with both conventional and synthetic motor oils, Les Frickshun ZINC offers immediate distribution of ZDDP package and will not coat your oil filter thanks to its special carrier. Best of all since one quart of Les Frickshun ZINC replaces a full quart of oil you can actually save money rather than buying an extra additive. So, for all of you racers out there running a motor with a flat tappet camshaft, you owe it to yourself and your engine to take a look at Les Frickshun's product line.
