The Castrol Alphasyn™ EP gear oil range of high quality synthetic lubricants are based on polyalphaolefin (PAO)
fluids and sulphur/phosphorus Extreme Pressure (EP) additive technology providing good thermal stability and
high load carrying capacity.
The Alphasyn EP range have been formulated for use in all types of enclosed gears including heavy and
shockloaded gears and bearings where EP properties are required. They are suitable for use in gear boxes where
micro-pitting resistance is required and for a wide range of applications in extreme environments, for example
mining and quarrying, marine applications and paper production.
The use of a PAO base stock provides an inherently high Viscosity Index (VI) and low pour points making these
products suitable for use over a wide temperature range.
The Alphasyn EP range is fully compatible with nitrile, silicone and fluropolymer seal materials.
