Castrol Optigear Synthetic ALR 150 equivalents
These are other published oils in the same application and the same ISO grade (or within 10 percent on KV40), from a different brand, with a compatible base oil. A score of 60 or more is the bar for this page. The score is typical data-sheet values only. None of these is an exact equivalent, and the machine builder's specification still governs.
