AVBLEND Helps: Prevent Rust AVBLEND Helps: Reduce Premature Wear AVBLEND Helps: Prevent Valves From Sticking In the Air and On the Ground... Always Working! For use in the engine oil, AVBLEND's formula has been around since 1937, where it started out in the racing industry and then was introduced to the automotive market as zMAX Micro-lubricant. The FAA later approved this same formula, to be known as AVBLEND, for use in piston-driven aircraft engines. AVBLEND is used by mechanics, the occasional pilot to the professional aerobatic stunt pilot, such as Sean Tucker. During an air show, AVBLEND helped Sean stay out of Lake Michigan after a blown oil line (read his amazing story). This same great formula is also used as zMAX Micro-lubricant in vehicles, for heavy duty use, small engines, locomotives and firearms. By soaking into metal to reduce harmful carbon build-up, AVBLEND helps provide provide lubrication in dry starts before the oil gets warmed up and flows easily. This aids in protecting against damage, friction and premature wear on internal parts. AVBLEND is the only product of its kind to be approved by the FAA for aircraft piston engines. Its flight-proven performance has given peace-of-mind to pilots and mechanics for decades!
