What is AVBLEND?
AVBLEND is the only product of its kind approved by the FAA for aircraft piston engines. AVBLEND is a tenacious micro-lubricant with reformulated micro-molecules that penetrate, clean and protect metal from the inside out. AVBLEND soaks into the metal. 

Is AVBLEND FAA Approved?
Yes. AVBLEND is FAA approved for aircraft piston engines; it is the only product of its kind to receive FAA approval. 

Is AVBLEND compatible with all engine oils?
Yes. AVBLEND is compatible with all conventional and synthetic oils. 

When do I use AVBLEND?
We recommend using AVBLEND with each 25-hour oil change for best results, not to exceed 50 hours between oil change intervals, or a total of four (4) months maximum between oil change intervals, whichever comes first. 

How much AVBLEND do I use in my engine?
Add one (1) 12 oz. can of AVBLEND to 4 cylinder engines (4 - 8 quart oil system capacity). 
Add two (2) 12 oz. cans of AVBLEND to 6 or 8 cylinder engines (9 quart or more oil system capacity). For other oil quart capacities, please call our technical line. 
NOTE: The Continental TSIO and IO-360 series engines have an 8 quart oil system capacity and will require only one (1) 12 oz. can of AVBLEND at each oil change interval. 

How long will an AVBLEND treatment last?
AVBLEND is a progressive lubrication treatment program -- not a quick-fix, one time treatment in a can. AVBLEND treatment is recommended at each oil change interval because AVBLEND continuously soaks in and weeps from treated metal surfaces. For additional protection while your aircraft is in long-term storage, we recommend that you treat your engine with AVBLEND prior to your last flight before storing your aircraft. By properly replenishing AVBLEND, your aircraft engine will receive the necessary continuous protection between oil changes. 

How will AVBLEND help my used engine?
AVBLEND can help restore and maintain your used aircraft engine to improved performance levels -- providing protection against rust, corrosion, dry start damage and premature wear. AVBLEND's unique penetrating ability slowly dissolves carbon and helps to improve valve and ring sealing in the combustion chamber. This provides better cylinder combustion (peak pressure) efficiency resulting in improved engine horsepower. Engines must be at least dimensionally correct within service limits to restore performance. 

Can I put AVBLEND into a used engine and is there any limit on the amount of hours for a used engine?
AVBLEND can be used on any aircraft piston engine regardless of its hours in service. 

Does AVBLEND replace my regular engine oil?
No. Install your premium engine oil quantity as the manufacturer recommends. Then install the recommended amount of AVBLEND to your oil system. Upon opening the can, the AVBLEND contents must be used completely. For best results we recommend installing AVBLEND into the engine and starting immediately for best distribution. 

In a six cylinder engine, can I use one can of AVBLEND each 25 hours instead of installing two cans?
Because most 6 cylinder engines have a larger cubic inch displacement and increased internal surface area, we recommend that two (2) cans of AVBLEND be installed at each treatment to insure proper surface area coverage and protection. 

Is AVBLEND ok to use in turbo-charged engines?
Yes. AVBLEND works very effectively in high temperature environments persistent in turbo-charged engines. 

How do I install AVBLEND to protect my engine for storage?
We recommend installing AVBLEND in your engine's last flight before placing the engine in storage. 

Can I use AVBLEND with the Lycoming LW-16702 oil additive?
Yes. 

Can AVBLEND be used in my fuel system?
No. AVBLEND is currently FAA-approved only for your aircraft's engine oil system. 

Will AVBLEND reduce my cylinder head and oil temperatures in my engine?
Many operators have seen reductions in cylinder head and oil temperatures. AVBLEND helps reduce high metal surface temperatures inside your engine (caused by raised machining imperfections) so lubricants and fuels moving across these surfaces can do the job they were designed for. 

Will AVBLEND help reduce oil consumption?
If parts are within at least service limits, AVBLEND has helped reduce oil consumption for many owners by penetrating and slowly dissolving carbon deposits and varnish on combustion chamber components. This produces less ring blow-by, reduced oil oxidation and contaminants, increased oil cleanliness, and a better lubricity seal between the rings and cylinder walls. Remember that if cylinder bores are out of round or pistons and rings have lost their tolerances, we recommend that the cylinder in question be removed and repaired. 

What does AVBLEND do for a new engine?
AVBLEND is the best measure you can use to protect your new investment against your engine's silent enemies: RUST, CORROSION, DRY STARTS, and PREMATURE ENGINE WEAR. 

Is there any benefit in using AVBLEND during the break-in period on my new or rebuilt engine? 
AVBLEND keeps friction surfaces cool during break-in period. One of the most important functions performed by AVBLEND is its ability to keep friction surfaces relatively cool while the metal is new -- during the break-in period. Too much heat during this critical period while the metal is forming itself into its job can easily cause brittleness, loss of flexibility and a tendency to break under sudden and severe strains. AVBLEND allows metal to temper itself under working conditions and assume the right degree of suppleness and hardness for the job it is intended to do during its entire performance life. This is known as work tempering (energizing) and can only be accomplished under conditions where excess frictional heat is reduced. AVBLEND allows proper break-in to occur while reducing conditions for cylinder wall glazing during the initial hours of a new engine's life. 

Is there a problem with installing AVBLEND shortly after my oil change interval?
No. Just install the recommended amount of AVBLEND to your engine's oil system and fly the aircraft. 

Will AVBLEND void the manufacturer's engine warranty?
No. If a failure occurs on a manufacturer's engine, the manufacturer would have to provide positive proof that AVBLEND caused the failure in question.

How important is Oil Analysis? 
As humans get medical physicals, aircraft engines need periodic preventive maintenance oil analysis. We recommend you follow your manufacturer's instructions or perform analysis every 100 hours of flight operation. For more information on performing your own engine oil analysis testing, please contact Aviation Laboratories
