CamGuard Aviation Oil Additive for Ultimate Engine Protection

What does CamGuard do inside a piston aircraft engine?

CamGuard uses an eleven component formula that targets the main causes of engine wear. It reduces metal to metal contact at startup, inhibits corrosion on internal surfaces, helps prevent varnish and carbon deposits, and conditions seals to keep them flexible and reduce leaks. The goal is longer engine life and lower maintenance costs.

What types of aircraft engines can use CamGuard?

CamGuard is made for piston aircraft engines, including popular Lycoming and Continental powerplants found in trainers, charter aircraft, and personal planes. It is also used in vintage warbirds and radial engines. It is intended only for piston engines and integrates into standard oil maintenance for both fleets and individual aircraft owners.

Is CamGuard compatible with synthetic and mineral aviation oils?

Yes. CamGuard is designed to work with mineral, semi synthetic, and fully synthetic aviation piston engine oils. It is added to your existing oil rather than replacing it, so you can keep using your preferred brand and viscosity while gaining its wear, corrosion, and seal protection benefits.

How much CamGuard do I add per quart of oil?

Follow the dosing printed on the bottle label, which specifies how much CamGuard to add per quart of oil. Add it at every oil change, and add the same proportion with each quart of makeup oil you put in between changes, so the protective ratio stays consistent throughout your engine.

How many quarts does one bottle of CamGuard treat?

Coverage depends on the bottle size you buy and the dosing printed on the label. A single standard bottle treats a typical small piston aircraft sump for one oil change. Owners with larger sumps or multiple aircraft often choose a larger size for better value per quart of oil treated.

Does CamGuard protect engines that sit idle or are flown infrequently?

Yes. Protecting idle engines is a core purpose of CamGuard. Its corrosion inhibitors guard internal metal surfaces during storage and between flights, which is when rust and pitting tend to form. This makes it popular for vintage aircraft, seasonal flyers, and any engine that does not fly every week.

Is CamGuard FAA approved or accepted?

CamGuard is described as an FAA accepted oil additive formulated for piston aircraft engine oils. It is not sold as a separate engine modification approval. Because it is an accepted additive used with approved aviation oils, it fits into normal engine operation without conflicting with standard maintenance requirements for most piston aircraft.

Will using CamGuard affect my engine warranty?

CamGuard is an accepted additive intended for use with approved aviation oils and integrates into normal maintenance protocols without affecting engine warranties when used as directed. If you have a specific warranty concern, confirm with your engine maker or your maintenance shop before your next scheduled oil change.

How often should I add CamGuard?

Add CamGuard at every oil change, and top it off with any makeup oil you add between changes. Each fresh fill of oil needs its own dose because the additive leaves with the old oil when you drain it. Keeping the dosing consistent maintains protection throughout the life of the engine.

How is CamGuard different from general purpose oil additives?

CamGuard is an additive built specifically for piston aircraft engines, with its formula aimed at corrosion, wear, and deposit protection. General purpose products such as Marvel Mystery Oil are not formulated or accepted as aviation engine additives in the same way. CamGuard targets the specific failure modes of aircraft piston engines.

What is the shelf life of CamGuard, and how should I store it?

Check the date printed on the bottle for the labeled shelf life. After that date you can visually inspect the contents, and if there is no separation or solid material present the product is generally still usable. Store it sealed at room temperature and away from extreme heat or freezing for best results.
