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.

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.

Yes, this is safe to use with 20W-50 Phillips 66 x/c.

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.

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

Yes. AVBLEND is compatible with all conventional and synthetic oils.

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.

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.

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.

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.

AVBLEND can be used on any aircraft piston engine regardless of its hours in service.

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.

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.

Yes. AVBLEND works very effectively in high temperature environments persistent in turbo-charged engines.

We recommend installing AVBLEND in your engine's last flight before placing the engine in storage.

Yes.

No. AVBLEND is currently FAA-approved only for your aircraft's engine oil system.

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.

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.

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.

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.

No. Just install the recommended amount of AVBLEND to your engine's oil system and fly the aircraft.

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.

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.

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.

Avblend recommends 4 cans in this case.

AvBlend will maintain its effectiveness so long as the seal is still intact, so no shelf life.

Yes, Avblend can be used with Phillips Victory oil.

Yes, we have added the MSDS sheet for the Avblend material to this webpage in the Documents section.
