Think Zinc for optimum engine protection and initial break-in.

Today's engine oil manufacturers and blenders continue to reduce or in some cases completely eliminate zinc compounds from their lubricates which can be very detrimental for engines using flat tappet camshafts and new performance engines during the initial break-in periods.

Why is Zinc an important additive?

Some of the most extreme temperatures and stress your new performance engine will ever see is during the initial break-in period. During this period every moving part in the engine is mating itself against a new surface which causes wear and high temperatures. Zinc's extreme pressure qualities aid in reducing piston ring-to-cylinder bore wear at BDC and TDC, where the rotating assembly sees an abrupt change in velocity and direction. Besides its extreme pressure protection, multifunctional zinc also functions as an antioxidant. That is, things exposed to heat and oxygen are subject to oxidation. In the case of a ferrous metal like iron, oxidation causes corrosion, which we see as rust. As heat accelerates oxygen, the oil starts to oxidize and thicken, changing into other molecular combinations. As the oil thickens, it forms deposits or varnish. In motor oil, the antioxidant additives first sacrifice themselves to prevent this oxidation from occurring, but if they get overwhelmed, the oil eventually turns into a hard, crusty sludge. In its antioxidant role, zinc fights heat buildup in various hot spots like the piston-to-piston ring interface and the underside of the piston itself. Oil can accumulate in the honing crosshatch marks in the cylinder bore where it is exposed to combustion temperatures as high as 400-450 degrees F, a prime candidate for oxidation if not protected. The same applies to flat tappet camshafts, especially in performance applications where the use of heavier valve springs increase the pressure between the lifter and the camshaft. Because zinc has been found to adversely affect OBD engine sensors, today's modern reduced-zinc passenger-car street oils contain other dedicated antioxidants to make up for the loss of zinc.

Les Frickshun Products zinc additive is compatible with conventional and synthetic base motor oils. It is packaged in quarts for easy no hassle, no mess use. By replacing one quart of your favorite engine oil with a quart of Les Frickshun Zinc additive during a 5 quart oil change will enhance your oil to a 1500 parts per million level of zinc protection.
