Mobil Extra Heavy 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 |
|---|---|---|
| Chevron Clarity Machine Oil 150 | 75 | same ISO 150, VI 101 vs 96, additive aw/ro, conventional, pour -15 vs -21 |
| Castrol Hyspin AWS 150 | 67 | same ISO 150, VI 95 vs 96, additive aw, conventional, pour -15 vs -21 |
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.
