Description
Castrol Optigear Synthetic X 320 AD is a specially formulated package designed for use with Optigear Synthetic X gear oil range. Optigear Synthetic X 320 AD is a concentrated form of Optigear Synthetic X 320 with carefully balanced additive levels, which allows direct addition into gearboxes containing Optigear Synthetic X 320. Optigear Synthetic X 320 AD is designed for use with systems already running on Optigear Synthetic X 320, where there has been some additive depletion either through normal or extended running life (and the additive has worked to protect the moving parts) or where contamination may have reduced the normal additive concentration.
