ASL CamGuard is an advanced Oil Supplement that addresses the complex and interrelated problems of corrosion, wear, deposits and seal degradation in piston engines. It is compatible with, and designed to improve the performance of all oils including mineral based, semi-synthetic and fully synthetic types.
CamGuard is especially useful for infrequently used engines including aircraft, marine, motorcycles, emergency equipment, backup generators, classic and antique vehicles, agricultural and all seasonal equipment. CamGuard contains 11 multifunctional components. Each of these components has a primary function and at least one secondary function. This is how CamGuard achieves superior performance with the addition of only 5 volume percent.
What problems can CamGuard address?
Corrosion is the destructive attack of a metal by chemical reaction with its environment. Rusting applies to the corrosion of iron or iron based alloys such as steel.
In engines, corrosion manifests itself by causing material loss, surface property changes (pitting) and dimensional changes, dramatically increasing wear rates on critical steel components such as camshaft lobes, tappet surfaces and cylinder walls. It is this effect recognized by a major engine component reconditioner that led to the development of CamGuard. Corrosion attacks of non-ferrous metals can damage bearings and bushings, degrade the efficiency of oil coolers and weaken structural components.
Wear is the gradual removal of material from one or both pieces of two materials that are in contact and moving relative to one another.
Engines have many parts found under such conditions including the interfaces of cam lobes and lifters, cylinders and piston rings and gears. Wear rates are determined by load pressures, relative speed, materials, surface properties and the lubricant. The existence of corrosion on the rubbing surfaces dramatically increase wear rates as the corrosion products are easily removed and often abrasive. Deposits that limit or prevent the normal movement of components will also increase wear rates dramatically.
Deposits are buildup of carbonaceous materials caused by oxidized fuel and lube products sticking to various engine components.
Reactive deposit precursors attach to metal surfaces and are then baked in place. The oil additives must prevent oxidation and disperse the reactive precursors for the life of the oil. If they don't, deposits can form, for example, on pistons causing rings to stick. Sticking rings rapidly increases wear and may cause the need for a premature top overhaul. Increasing both antioxidancy and dispersancy capabilities of the oil help minimize deposit buildup as well as mitigate existing deposit problems.
Seals are synthetic rubber like materials that allow mechanical motion to occur outside the engine while keeping the oil inside the engine.
They seal the crankshaft while allowing it to turn both inside and outside the engine and their use allows access to many parts of the engine including valve covers and push rods. Over time and exposure to hot oil, seals may shrink and harden or they may soften and crumble. Neither is a pleasant prospect. The ability to protect from both scenarios can help minimize messy engine compartments and the need to replace seals before TBO.
