    Mazda CX9 Rear Diff - Mobil 75W90

    The transfer case appears to be made by Ford......the engine is a 3.7L Duratec - Ford also. Wedged in sideways! There is other stuff that is not Mazda as well. Transmission off the top of my head is Asian. No problems with its operation - However I do not agree with the "do not service" concept...

    Mazda CX9 Rear Diff - Mobil 75W90

    The Mazda service centre wanted over $3000 - fitted. Unfortunately for them, I had prepared in case of what I thought it was - prior research prevents getting ripped! Bought mine from the US, airfreighted and delivered for under $700. Guy to install was about $400. Bit of a price difference...

    Mazda CX9 Rear Diff - Mobil 75W90

    Mazda CX9 Rear Diff - Mobil 75W90

    Hello, Mazda CX9 AWD, changed the rear differential oil at 100,000km (62,000 miles). The oil removed was looking good - nice honey colour. No junk on the magnetic drain plug. Refilled using Mobil 1 75W90 LS. The manual specifies a GL5 80W90. I have just dropped it 5000km later (3000 odd...

    5w30 in Mazda CX-9

    For what it is worth: The owners manual for our CX9 (Australia) specifies 10W30, 10W40, 5W40 and 5W20. The ambient conditions where I am are not too far off something like Socal. I have been running 5W40 in mine with no problems. Was using Elf Excellium 5W40 for quite a while, but got hold...
