Why does the manual say I don't ever need to change my diff oil?

    I'm coming up on 30K miles here so I was looking at the "Scheduled Maintenance Guide" that came with my owners manual.

    It says that at 30K, the rear diff oil change is recommended "only for Preunners and 4wd vehicles with an optional limited slip differential". It goes on to say that those trucks without a limited slip only need to "inspect" the diff oil....I have a 2009 Prerunner SR5, which does not have a mechanical LSD.

    So I got to looking through the other mileages and at no point at all does it say the diff oil in a non-lsd truck needs to be changed, ever.

    This seems ridiculous to me, and I'm going to change the diff oil at 30K regardless, unless someone convinces me otherwise.

    I wanted to see what others have to say about this, or am I just reading it wrong? :notsure:

    I think it means change as needed. I would go ahead and change it too, it wont hurt.

    I changed mine to 75W-90 Mobil 1 synthetic at around 45k miles. I'm at 86k now and will be changing it again soon.

    That's what I assume, but one would think that Toyota might suggest that it would be "needed" at some point in the first 120,000 miles of the life of the vehicle :laugh:

    I would switch it over to synthetic and let that go 60k.

    Did the oil look like it needed to be changed in your opinion?
