Small Engine

Increased Dependability with CamGuard Small Engine (4-stroke)

For those who depend on their 4-stroke, small engine workhorses for emergencies or making a living, you know they represent a substantial investment and must be reliable. Small engines work harder than most people realize, whether used continuously during emergencies or in seasonal demands, and then suddenly, boom – they get returned storage. You depend on your commercial and emergency equipment to start, demand maximum performance and then expect years of trouble free service. Read on to learn how CamGuard Small Engine helps you achieve reduced maintenance downtime and longer life for your infrequently or intermittently used small engines.

CamGuard Small Engine is a blend of high performance additives that fortify small engine motor oils to provide the utmost in engine protection. The latest small engine oil formulations are at best a compromise due to cost, new oil specification delays and government regulations. Cost pressures lead to reduced additive concentrations as well as the inability to utilize the latest additive technology, both of which lead to less than optimum performance.

CamGuard Small Engine delivers un-compromised performance using the most advanced additive technology available to dramatically reduce friction and wear, decrease deposit formation and prevent corrosion when used in today’s commercial automotive oils.

CamGuard Small Engine contains advanced anti-wear additives that provide a dramatic reduction in wear when compared to current ZDDP (zinc) containing oils.

CamGuard Small Engine contains powerful multi-metal corrosion inhibitors that prevent rust and corrosion in seasonally or infrequently used engines.

CamGuard Small Engine utilizes the latest generation of friction modifiers that pro- vide a reduction in oil temperature.

CamGuard Small Engine utilizes advanced antioxidants to prevent cylinder varnish and ring belt deposits. This is particularly important in the hot running environment of today’s higher output engines.

CamGuard Small Engine contains seal conditioners that nullify the effects of heat and time to keep seals supple, flexible, and performing like new.


CamGuard Small Engine is available in an 8oz bottle.
Add 1oz to each quart at each oil change.*

We tested four of the top selling oils, two conventional and two synthetic, utilizing a FALEX PIN and Vee-block tribometer at an independent analytical laboratory. The Phillips Petroleum designed procedure used is a derivative of ASTM D-2670 and is described in the Scientific Journal “WEAR”. The procedure correlates very well with camshaft wear in engines using gasoline and diesel engine oils.

The often-cited 4-Ball wear test does not correlate to engine wear.


 In the graph above, the red bars show the wear for each of the untreated oils. The blue bars are the corresponding oils with addition of 3% CamGuard Small Engine and reflect the remarkable reduction in wear and demonstrate a true advancement in anti-wear technology when compared to the standard “zinc” anti-wear chemistry.

The CamGuard Story began with CamGuard Aviation
which was developed as an ultra-high performance aviation product.

The photos above are pistons removed from two different Lycoming IO-540 aircraft engines. The piston on the left is from our 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. Because of this extraordinary experience, we expanded the CamGuard family to include other applications.  To learn more about why CamGuard Aviation was created click here.

CamGuard is the only lubricant product to undergo certification testing in the extremes of aerobatic use and the first product ever tested at large public gatherings. During certification nearly one million people witnessed CamGuard in action at air shows throughout the US.
