Thanks for your inquiry. The 1150 Trans-All EHP fluid is a blend of synthetic and paraffinic base oils, plus several proprietary additives. A 5-gallon container is $131.05 (shipping included).
With the specs listed (viscosity index 200), I doubt that you have to worry about there being much wrong with the base oils used. As a rule, LE seems to use paraffinic base oils for their additive packages. Better solvency maybe? I don't know for sure though.
