Castrol Optigear 1100/1000 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.
| Oil | Score | Why |
|---|---|---|
| Shell Omala S2 G 1000 | 78 | same ISO 1000, VI 85 vs 83, additive ep, conventional, AGMA AS |
| Chevron Meropa 1000 | 67 | same ISO 1000, VI 106 vs 83, additive ep, conventional, pour -22 vs -18, AGMA AS |
Scores use published typical data. This is not an exact equivalent, and it is not an OEM approval. Confirm the substitute with the machine builder.
