Alphasyn PG
Synthetic gear oils

Description
The Castrol Alphasyn™ PG gear oil range of synthetic lubricants are based on polyalkyleneglycol (PAG) fluids enhanced
with antioxidants, rust inhibitors and Extreme Pressure (EP) additives of high thermal stability.
Application
Alphasyn PG gear oils are primarily intended for use in worm reduction gear boxes, where the low coefficient of friction of
the PAG base fluid improves efficiency and consequently reduces power consumption and operating temperatures. This
is particularly important in applications where sliding contact is high. The use of a PAG base stock provides inherently high
Viscosity Index (VI) and low pour points making these products suitable for use over a wide temperature range. Alphasyn
PG meets the requirements of most OEM’s that allow the use of PAG based gear oils.
Advantages
Low coefficient of friction reduces energy consumption and lowers operating temperatures, this leads to longer
oil life.
Good thermal and oxidative stability provides reliable operation and extended operating life when compared to
mineral oil based products.
Inherently high VI makes the product suitable for operations over a wide temperature range.
High load carrying capacity and good wear protection reduces maintenance.
