A9 Lubricants

ACE is the only US distributor of  A9 products and is presently expanding its inventory and online store.

With the unique properties to prevent corrosion and at the same time reducing friction, A9 is the only patented surface engineering treatment with sub micron sized particles that are “miscible” in the oil. All the others use solvents of various types to create a “solution” that mixes with the oil. These solution type products modify the base oil and can void the manufactures warranty. A9 as it is “MISCIBLE” uses the oil solely as a transport mechanism within the engine. Once the engine temperature reaches 43C (109.4F) the sub micron size particles adhere to any metallic surface. The particles are extremely small, in fact they are 0.1 micron, this allows them to easily move unhindered past the oil filter unlike other products that are only a several microns in size which ultimately clog up the oil filter. The other secondary benefit is the reduction in friction and hence a lower sump temperature. Under controlled conditions at the University using the ball on disk test, plates that were conditioned with A9 showed a remarkable reduction in friction.

The product comes in a syringe that you simple add to the oil bath during a change. Once the aircraft engine is treated with the A9 the treatment will last approximately 300 hours before it will begin to wear. Keeping a small amount of A9 in the oil will continue to replenish metallic surfaces thus protecting for years.

CAUTION, Do not add A9 to a new engine that has not yet run, A9 is so effective that it may not allow the rings to properly seat.

Engine Type Treatment Size

60ml tube of Motoreco PL has 30 grams of A9 “mother”. This single treatment will treat up to 30 quarts of oil. For best use I add tube to one quart of common oil and then add 1 oz. of this mixture per quart I am treating. Best to add after oil change, you can then double your normal oil change schedule.

A9 is NOT an oil treatment, it is an ENGINE treatment and uses the oil only as a transport mechanism.

A9 is “MISCIBLE” and does NOT change the manufactures warranty as it has absolutely no effect on the oil, it’s viscosity or the additives in the oil.

Handling of A9 is safe. Other additives use toxic chemicals and are very dangerous to health and the environment.
