CamGuard is a blend of high-performance additives that fortify piston aircraft oils to provide the utmost in engine protection. Because of FAA regulations and costs, even the newest commercial aircraft oil technology is antiquated. Interrelated problems of corrosion, deposits and wear in air-cooled piston aircraft engines have been addressed as the supplement contains powerful multi-metal corrosion inhibitors that prevent rust and corrosion in infrequently used engines.

Infrequent engine us can lead to rust pits forming on cam and lifter surfaces. This pitting can result in catastrophic spalling swear requiring a premature engine overhaul. The Supplement also contains advanced anti-wear additives to dramatically reduce the wear of cams, lifters, cylinders, rings, gears, and valve guides. CamGuard also prevents scuffing wear from "dry starts" by maintaining an active lubricant film on critical parts, even after periods of prolonged activity and utilizes unique ashless deposit control additives that prevent the formation of varnish and carbon deposits throughout the engine. Use in older engines allows component motions to free up sticky rings and valves, increasing compressions and reducing oil consumption. Seal conditioners nullify the effects of heat and time to keep seals supple, flexible, and performing like new.

Four of the top selling piston aircraft oils were tested for corrosion resistance with and without the addition of CamGuard Aviation. The testing was performed at an independent laboratory utilizing the DIN 50017 humidity cabinet test. The DIN 50017 method demonstrates excellent field correlation, unlike the obsolete ASTM 1748 humidity cabinet test.

The graph indicates the average number of days until failure, which is defined as the observation of three 1mm spots of rust on the steel test panes. The red bars indicate time to failure for the untreated oils while the blue bars represent the corresponding oils with the addition of 5% CamGuard Aviation. All the oils show a remarkable improvement with the addition of CamGuard Aviation.

The photos above are pistons from two diﬀerent Lycoming IO-540 aircraft engines. The piston on the left is from an FAA certiﬁcation engine using CamGuard for 500 hours. The certiﬁcation test was in an aerobatic aircraft that utilized very high-power settings resulting in extremely high temperatures. The piston on the right was taken from a non-aerobatic aircraft engine that was ﬂown at typical cruise power settings, without CamGuard, for 500 hours. The diﬀerence in deposits is striking.

AeroShell and Phillips engine oil also available. For details go to Engine Oil.
