SAE 90 oil is equivalent to an ISO viscosity grade of approximately 220. It is commonly used in applications requiring a heavier gear oil, such as in automotive differentials and manual transmissions. Additionally, SAE 90 oil can be compared to certain grades of 85W-140 oil, though the latter may have different performance characteristics due to its broader temperature range. Always consult manufacturer specifications for optimal performance.
