  • Overview
    The only product of its kind, AVBLEND is a unique "micro"-lubricant. AVBLEND molecules have been reformulated to be smaller than regular oil molecules. The results of this reformulation allow AVBLEND to soak deeper into the metal than any other lubricant. AVBLEND penetrates, cleans, lubricates and protects aircraft piston engines from the inside out.

    AVBLEND uses your aircraft's engine oil as a carrying agent to reach metal working surfaces inside your engine. When your engine reaches operating temperature, AVBLEND soaks into the metal surfaces. Once AVBLEND has penetrated the internal components of an engine, the parts are continuously lubricated and cleaned. Continuous use of AVBLEND helps reduce future harmful carbon deposit buildup.

    If you were to look at the metal in your engine through a microscope, you would see that the surface is far from smooth. You would see peaks and valleys, blunt and sharp edges. Your aircraft engine's oil moves over the surface doing its best to provide lubrication. However, the oil molecules are too large to provide penetration in the small grooves and protect the entire surface of your engine. AVBLEND's depth-soaking molecules are small enough to fill in these tiny nooks and crannies and penetrate deep into the metal, thus providing better lubrication with moving pieces. Plus, AVBLEND cleans the surface from harmful deposits.

    Operational Cost-Savings
    The chart, right, provides an average cost of performing a single cylinder or top overhaul repair on four and six-cylinder aircraft engines. Labor pricing is based on an average shop rate of $50.00 per hour. Costs stated below do not include tax, shipping or lost revenue while the aircraft is grounded for these repairs. Using AVBLEND at every oil change costs considerably less than a single cylinder replacement, and a fraction of more costly repairs. Not only is AVBLEND solid preventative maintenance, but it provides an added level of safety and security by reducing the chance of compression loss and the resultant decrease in horsepower.

    Dry-Start Damage
    After initial start-up, although oil pressure registers on the cockpit gauges, it can take an additional 45 to 120 seconds for oil to reach critical parts of your engine. Starting your engine is the major cause of engine wear. The piston (below left) removed at overhaul shows severe thrust side scoring which is common when AVBLEND is not used. The piston (below right) shows thrust side commonly seen at TBO using AVBLEND.

    Rust and Corrosion
    Most aircraft owners, quite simply, don't fly their airplanes enough. These periods of inactivity can cause irreversible rust and corrosion which can lead to premature replacement of expensive internal engine parts. The camshaft (below left) shows significant rust and corrosion damage which resulted in premature replacement. The camshaft (below right) was protected by AVBLEND and made it to TBO still within factory limits.

    Carbon and Deposit Build-Up
    Leaded aviation fuels combined with high operating temperatures create an environment for carbon and deposit build-up in the most critical areas of your engine. AVBLEND kept the exhaust guide (below right) virtually carbon free and dimensionally correct while the unprotected guide (below left) shows significant carbon.

    Valve Stem Deposits and Wear
    Carbon and deposit build-up (below left) can cause valve sticking and excessive valve stem and guide wear which can lead to catastrophic engine failure. AVBLEND (below right) can help to minimize these potentially dangerous deposits and wear.

    For new and rebuilt engines AVBLEND helps:
    • Prevent build-up of carbon, and deposit build-up commonly found in high temperature air cooled engines
    • Reduce damaging dry starts, which can prematurely wear out the internal parts of your engine before reaching TBO
    • Prevent rust and corrosion damage during periods of inactivity
    • Reduce the potential of unnecessary maintenance costs due to premature wear (ie low-compression cylinder removal) at your aircraft's inspections
    • Keep new and rebuilt engines dimensionally correct from rebuild to TBO
    • Maintain performance and efficiency over the lifetime of the engine
    For used engines AVBLEND helps:
    • Clean your engine by dissolving existing carbon and deposit buildup commonly found in high temperature air-cooled engines
    • Restore lost performance and combustion efficiency to engines with accumulated hours

    by Cecil L

    Ive used AVBLEND at every oil change in my 1975 Cessna 150M since I bought it in may 2011. (Change the filter every 25 hours and oil every 50 hours). The engine is at 1,450 hours SMOH and compression remains 78, 78, 76, 74. Im convinced paying an extra $100 a year for the AVBLEND will delay at least a year or two in having to pay $20,000 for an OH or REMAN on the Continental O-200. Pretty good investment, in my humble estimation!

    by Ryan

    This product will not provide the protection you need if your aircraft sits for a couple weeks between flights. If you read about the actual lab testing of products like this and camguard, camguard definitely will help protect your engine more, especially if you live in a higher corrosion environment. It all depends on your type and frequency of use!

    Fast and great service as always

    by Rich B

    At this point no real way for me to evaluate this miracle in a can as my Aero Sport 0-360 only has 260 hrs on it , but anything I can do to protect a $24,000 investment seems to be the prudent thing to do .

    I wont fly my airplane without it. I swear by it. My engine is trouble free and I attribute it to Avblend.
  • Q+A

    Ask a question

    I use zmax in my cars faithfully and love it...is avblend the aviation version...if so, how is it different?
    Per the supplier: Yes, Avblend is the aviation FAA approved version. There is no other difference than Avblend is for aviation and Zmax is not.

    I am using TCP fuel additive. Can I also use Avblend for my oil? Are they commonly used together?
    Per the supplier: Yes. There is no problem using AVBLEND in the oil system and TCP in the fuel system at the same time. We DO NOT recommend other oil additives mixed with AVBLEND.

    Is it safe to use AvBlend Lubricant with 20W-50 Phillips 66X/C even though it has additives?
    Yes, this is safe to use with 20W-50 Phillips 66 x/c.

    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).

    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?

    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.

    Question about AVBLEND. First in your question and answer about CAMGUARD you said when using shell 100 PLUS camguard will do nothing because shell 100 plus already has the same additives. My question is: is the same true with AVBLEND you do not need it if you are using shell 100 plus because it already has the same additive as AVBLEND?
    The Aeroshell Oil Plus product contains an anti-wear additive for Camshaft protection. This goes back to Shell and Lycoming getting together and putting the same additive into the Shell Oil and separately in Lycoming’s LW-16702 additive for premature 0-320-H2AD Cam/Lifter issues. The definition of an additive is something added to the oil base stock to enhance its properties which is what the Shell Oil and Lycoming additive accomplish. Regarding AvBlend, it’s a pure Micro-Lubricant (not an additive) that does not enhance the engine oil base stock but uses the oil as a carrier to reach and literally “Soak into the Metal” deeper than engine oil alone. (82 X deeper proven through independent Auger Election Spectroscopy lab testing) AvBlend unlike any additive or engine oil, penetrates the metal and weeps out providing additional lubrication protection during storage,start-up and flight. This mode of action dissipates surface heat to reduce oil oxidation on the hot metal surfaces such as cylinder walls, pistons, exhaust valves/guides and other parts as well. AvBlend also disperses harmful deposits and then helps maintain what it cleans because it continuously weeps out of the metal making it difficult for deposits to reform on a surface that weeps out oil. In conclusion, AvBlend IS NOT in any Aeroshell Oil Product. Back when I owned and operated Blueprint Aircraft Engines years ago, this question was always asked. In fact, after years of disassembling engines using just Aeroshell Oil vs engines with AvBlend added, there was a clear difference in cleanliness and reduced wear.
