I just bought a 2023 Mazda CX-5 and I didn't see anything in the owner's manual about how often to change the differential fluid. Does anyone know how often this must be done? Is this information in the owner's manual and I just missed?

Thank you.

 

Mazda doesn't have a specified fluid change interval for the Diff, PTO ( transfercase) or transmission.

My personal advice is to change them all every 30,000 miles.
