2016 Mazda CX-5 GT AWD w/Tech Pkg
- Plano, Texas, USA
Mazda has never had an ATF replacement schedule in their Schedule 1 (normal driving conditions) and Schedule 2 (severe driving conditions) maintenance. They claim the ATF is lifetime.⋯ More aggressive than the currently recommended 30K mi interval? Or does that suffice?
On gen-1 CX-5, there’re a couple of notes, *5*6, for rear differential oil; and a note, *6, for transfer oil on maintenance schedule:
*5 If the vehicle is operated primarily under any of the following conditions, replace the rear differential oil at every 48,000 km (30,000 miles).
a) Towing a trailer or using a car-top carrier
b) Driving in dusty, sandy or wet conditions
c) Extended periods of idling or low speed operation
d) Repeated short trips of less than 16 km (10 miles)
*6 If this component has been submerged in water, the oil should be replaced.
But for gen-2 CX-5 both rear differential oil and transfer oil have only one note, *4, on maintenance schedule:
*4 If this component has been submerged in water, the oil should be replaced.
So if I were you, I’d replace ATF in transmission、gear lube in rear differential (might as well the front transfer case) at 30,000 miles like ColtX-5 has been doing (unless I haven’t been towing within that period).
