AVBLEND FAA-Approved Micro-Lubricant for Aircraft Piston Engines
Trusted by pilots and mechanics for over 30 years, AVBLEND® is the only FAA-approved micro-lubricant for aircraft piston engines. Its ultra-fine molecules penetrate deep into metal surfaces, reducing carbon buildup and providing critical lubrication during dry starts. The result? Peak combustion performance, lower temperatures, cleaner valves, and longer engine life.
Why Choose AVBLEND?
- ✔ Reduces carbon deposits that cause blow-by and valve sticking
- ✔ Lubricates during dry starts before oil circulation begins
- ✔ Lowers operating temperatures and reduces engine wear
- ✔ Prevents rust and corrosion between flights
- ✔ FAA-approved—the only product of its kind
Real-World Results
In a 1,100-hour endurance test by Enstrom Helicopters, AVBLEND-treated Lycoming engines showed less than .001" of wear on exhaust valves. Acrobatic pilot Sean D. Tucker's engine ran for 6 minutes with zero oil pressure and emerged without damage—thanks to AVBLEND.
How to Use
- ➤ 4-cylinder engines: Add 1 bottle (12 oz)
- ➤ 6- or 8-cylinder engines: Add 2 bottles (24 oz total)
- Run engine for 30 minutes after adding for full absorption

Frequently Asked Questions about AVBLEND
Is AVBLEND FAA approved for use in piston aircraft engines?
Yes, AVBLEND is the only micro-lubricant approved by the FAA for use in certified aircraft piston engines. It's a proven way to reduce engine wear, carbon buildup, and valve sticking in Lycoming, Continental, and other engine types.
Can I use AVBLEND in my Lycoming IO-540 or Continental O-200 engine?
Absolutely. AVBLEND is commonly used in Lycoming and Continental engines, including the IO-540 and O-200 models. It helps reduce dry start friction, lowers engine temperatures, and protects valves and piston rings from excessive wear.
What’s the benefit of AVBLEND during cold starts?
AVBLEND provides lubrication before traditional oil reaches critical engine parts, helping prevent metal-on-metal contact. This makes it ideal for aircraft frequently subjected to cold starts or long storage periods.
Does AVBLEND help prevent rust in stored aircraft engines?
Yes. AVBLEND penetrates the metal to prevent internal rust and corrosion from condensation, which is especially important when storing aircraft for extended periods.
How is AVBLEND different from regular oil additives?
AVBLEND isn’t just an oil additive—it’s a micro-lubricant. Its molecules are smaller than oil molecules, allowing it to soak into metal surfaces and protect against carbon buildup and friction where oil alone cannot.
How do I use AVBLEND in my engine oil system?
For 4-cylinder engines, use one 12 oz bottle. For 6- or 8-cylinder engines, add two 12 oz bottles. After adding, operate your engine for at least 30 minutes to allow the AVBLEND to fully soak into the metal surfaces.
Where can I buy AVBLEND with free shipping?
You can buy AVBLEND directly from Air Power Inc—a factory-authorized distributor. We offer free U.S. ground shipping, no order minimums, and same-day shipping on most orders.
