Can you use sae 90 for Honda crv?

SAE 90 is typically a gear oil used for differentials and manual transmissions, not for engine oil. For a Honda CR-V, it is essential to use the oil grade specified in the owner's manual, which is usually a multi-viscosity oil like 0W-20 or 5W-20. Using SAE 90 engine oil could lead to improper lubrication and potential engine damage. Always refer to the manufacturer’s recommendations for the best performance and longevity of your vehicle.
