Can I Use 75W90 Instead Of 75W85?

It might be difficult and complicated to select the appropriate gear oil for your car. Many vehicle owners frequently question if one oil may be substituted with another. Yes, you can use 75W-90 instead of 75W-85, to help clear up any confusion.

Both oils provide outstanding protection against wear, rust, and corrosion and are multi-grade lubricants. However, 75W-90 has a higher viscosity and offers superior protection against harsh temperatures and heavy loads. Because of this, GM dealers frequently use 75W-90 gear oil in instances where Chevrolet/Buick/GMC/Cadillac recommends 75W-85.

Note, however, that while 75W-90 can be used in place of 75W-85, 75W-85 should never be used in place of 75W-90. This is due to the lower viscosity of 75W-85, which would not offer the same amount of protection for your car.

Overall, choosing 75W-90 instead of 75W-85 is a totally adequate replacement that can give superior protection against high temperatures and heavy loads. Therefore, if you are unclear about which oil to use, it is always advisable to visit a professional who can offer you with the correct information.
