The product ARX is a proprietary blend of three ester groups. One is fatty ester, lanolin type, that is the base of ARX. Raw material is derived from the washing of sheep hair. This unique ester has very good detergent properties and is reponsible for most of the cleaning of engine deposits that motor oil detergents can't clean. A second ester group is an aliphatic ester, which helps in the oil film formation. Esters of this group make up the base of many aviation oils. They prevent dry spots or fish eyes in the oil film formation. This is obviously important while flying many thousand feet above the ground. It is also vital during the cleansing of deposits in your ground level motor. The other ester group is a polyol ester. Although is primarily used as a thinning agent of the ARX blend, improving pour point, they are biodegadeable eco friendly extreme pressue agents. By green I mean cholorine free, phoshate free, boron free, etc.
I like to think of ARX as relif pitcher in baseball. When the starting motor oil has failed due to errors such as ecessive length of oil changes, you have got to go to the bullpen. The starting motor oil wears down over the life of an oil change, at the pesty price of an internal motor problem, why not go to the bullpen, ARX maintenance dose. If you have seal leaks and can not justify a horendous labor charge to swap out a cheap seal, then go to the closer, ARX. Rick 20
