Regarding ZMax microlubricant -

These are the tests they claim to have performed, at a cost of $4.5 Million to "Oil-Chem", the parent company.

* SAE J1321 - designed to measure fuel economy changes of in-service vehicles.
* Auger Electron Spectroscopy - designed to measure the penetration of a material into a metal subsurface.
* Modified CRC L-38 - capable of measuring bearing, cylinder, piston and valve guide wear; horsepower; piston deposits; and oil deterioration.
* ASTM D4172 (Four Ball Method - Prevention of Wear) - designed to measure anti-wear properties of a lubricant.
* ASTM D5182 (Four Ball Method - Coefficient of Friction) - designed to measure the coefficient of friction of a lubricant.
* ASTM G99 (Pin on Disc Method) - designed to measure the coefficient of friction of a lubricant.
* ASTM D2174 (Block on Ring Test) - designed to measure the coefficient of friction of a lubricant.
* ASTM D1748 - designed to measure rust preventive properties of metal preservation.
* Modified Sequence VIII - capable of measuring bearing, cylinder, piston and valve guide wear; horsepower; piston deposits; oil deterioration, and fuel efficiency.
* TEOST MHT-4 Thermo-oxidation Engine Oil Simulation Test - designed to measure and emulate deposits that would occur in the piston and ring area of a modern engine.
* FTP 75 - designed to measure the emissions of a vehicle under normal city and suburban driving conditions.
* BAR 90 - designed to measure the in-use emissions level of vehicles for controlling air quality.


They do have an FAA approved lubricant, AVBLEND, which apparently is the same basic formulation, made from a base package of "Lenckite" (Linkite), derived from a famous racer back in the 50's, originally marketed as "Speedway Blend".
