Mazda CX-70 Transfer Case Service
The transfer case is the part of an i-ACTIV AWD® CX-70 that sends drive to the rear axle, and Mazda’s answer about servicing it is short: it specifies Mazda Long Life Hypoid Gear Oil SG1, gives a capacity of 0.51 L (0.54 US qt), and schedules no periodic replacement. We check it and we do not sell a flush on a mileage Mazda never printed.
What We Check on the Transfer Case
There is no scheduled service here, so this is an inspection and an honest report.

What Mazda Schedules
One sentence from Mazda covers the whole of it, and it is worth reading exactly.
Sourced from the Scheduled Maintenance section of the 2026 Mazda CX-70 owner’s manual, pages 9-5 to 9-7, together with its Recommended Oil and Lubricant Quality and Capacities tables. Your own manual is the authority for your vehicle; bring the mileage and our team will read the table with you.
The Oil and the Quantity
What Mazda names, for the times the case is opened for a repair.
Mazda Long Life Hypoid Gear Oil SG1
Mazda specifies Mazda Long Life Hypoid Gear Oil SG1 for the CX-70’s transfer case. Capacity is approximately 0.51 L (0.54 US qt).
Front Differential
Mazda Long Life Hypoid Gear Oil SG1, approximately 0.35 L (0.37 US qt), with the same note.
Rear Differential
Mazda Long Life Hypoid Gear Oil SG1, approximately 0.90 L (1.0 US qt). Mazda’s note: Replacement is necessary when the component is submerged in water.
When It Does Need Doing
Mazda’s condition is specific: Replacement is necessary when the component is submerged in water. A vehicle that has been driven through deep standing water is the case that meets it, and Mobile gets that weather. That is a flood-damage instruction rather than a maintenance interval, and we treat it as one.
What Mazda Counts as Severe Driving
Mazda publishes a severe schedule for the CX-70 and a three-condition list for deciding whether you are on it. Both are shorter than most people expect.
Mazda’s Severe Schedule Moves One Thing
On the CX-70, Mazda’s severe schedule changes the engine oil and filter to 5,000 miles or 6 months and states in as many words that every other item follows the interval listed in the normal schedule. There is no second table to move onto.
The Three Conditions
Mazda’s list, in its own terms: the vehicle is idled for long periods or driven at low speeds, such as with police cars, taxis, or a driver’s education school car; the vehicle is driven mainly on unpaved road; the vehicle is driven mainly on mountain roads or uphill roads. Those are the whole of it.
What Gulf Coast Driving Does Not Change
Mazda’s U.S. severe-driving list for the CX-70 names no weather condition — no heat, no humidity, no heavy rain, no short trips, no dust. Ordinary Mobile-area commuting matches none of the three, so a Gulf Coast CX-70 is a normal-schedule vehicle.

The Case That Does Meet It
Standing water on the Gulf Coast is the realistic version of Mazda’s condition. If the car has been driven through deep water, the gear oils are worth checking regardless of mileage.
