Identify Genuine Mazda Fluids

[Nesterenko]

Hello!

I visited a local Mazda Dealer for suggested fluid exchange services at 60k miles on my 2020 Mazda CX-5 AWD for the transmission, differential, and transfer case.

I am reviewing the receipt I got from service, and I noticed that the part numbers mentioned on the final invoice were not (at least obviously) Mazda part numbers for the fluids. I contacted the dealer, and asked if they used genuine fluids. They said they do, but part numbers may not match since they buy in bulk.

The part numbers...
Differential Fluid Service - EG7590S: "75W90 Synthetic Diff Fluid"
Transfer Case Service - EG7590S: "75W90 Synthetic Diff Fluid"
Transmission Fluid Exchange - TR200: "Synthetic MV ATF" AND SB100: "Trans Clean Cond 2-Stepkit"

I looked up the numbers and I found they match third-party products by Mighty Auto Parts. But, the dealer assured me they are genuine OEM.

I want to think the Mazda dealer knows what to use, but I can't help but feel slightly concerned with the Mighty part numbers.

Any insights would be much appreciated.

Thanks!

Did they charge you for premium OEM fluids just the same or for aftermarket fluids price?

My local Mazda does not use Mazda oil unless asked for specifically. Not sure what they use for standard oil changes. One of the service writers said he “thinks” they use Mobil. Not Mobil 1. Maybe bulk Mobil synthetic.

No idea on transmission either. My two Mazdas don’t take FZ. Whatever the newer stuff is. I have never seen an aftermarket for it yet.
