T-case/Diff Fluid Change Mazda 3 Turbo 

What could be damaged by an aftermarket oil? Considering it's around the same vicosity and it's oil actually made for transmissions and differentials. You mentioned TCC shudder but is that causing damage or just feelings.

This might be a dumb question but im new to working on my own car. Where and how do you refill both fluids? From the same plug they were drained? Thanks for the video

Another question for yah, does you car have any differential whine like some of the other turbo owners do? Is it something to worry about? Thanks!

Whats your opinion on Mazda's SG-1 fluid? Some people on the online forums suggest using Royal Purple 75w-90 instead as they think the SG-1 fluid isn't great.

what are your thoughts on a GL-5 fluid like Red Line 75W90 for the T-case + diff on the Mazda AWD?

Hi mate.. im having a problem. The dealership in my country doesnt have mazda SG1. Is there any other oil that can substitute for sg1? TIA

Were you able to do both with 1 qt? They suggested every 40k to me, wonder what I will find

How do you change the front transfer case fluid? Last time I went underneath the fill plug looked blocked by a bracket. The service manual seemed to indicate the need to remove lots of parts, more than I would comfortable removing in my gravel driveway!

Hello. I just did my first rear different and transfer case oil change service ever, at 22.5k miles but car is like 4 years old. Differential oil came out pretty clean, I couldn't see the other though. However, in my country I couldn't get Mazda SG1 and it's hard to import oil on my own. I didn't know about alternatives and my mechanic told me they use Motul so I was ok it must be great, but now when they drained it already I saw the bottle was Motul HD, it's 80w90 and seems to be non-synthetic. Googling around seems like Motul Gear 300 75w90 would have been the best alternative to OEM. Should I be worried to be running non synthetic 80w90? I also read that at same viscosity rates the difference in fluidity varies from non synthetic to full synthetic oils so like 80w90 according to specs seem to fluid more at 40°C than the Gear 300. Would this oil mess up and break my Differential? What do you think I should look for unexpected changed behavior so I can go and change to another oil before I break my car? There's also Motul Motyl Gear 75w90 but seems to be more focused to transmissions. I'm scared of breaking things. What do you think?

Does somebody tell me the gasket part number for the drain and fill plug for both the rear differential and transfer case, please? I just want to make sure before starting the job

What were the size of the bolts and the torque specs? Cannot find anything online.

At what mileage did you replace it. On the Mazda website it says for life but I think that’s bullshit especially with the some of the issues these cars have with the rear diff

Скажите какое масло туда заливать.
