    Hi all,

    I have 2017 outback 2.5 with 32,000 miles on it. I am heading to a local dealership for an oil change tomorrow.

    I have received a flyer from a local dealership, and from the listed things of a major service (30,000 miles / 3 years), the only noticeable thing was replace front and rear differential fluids. I checked the owner's mannaul maintenance schedule, and it says differential fluids should be inspected at 60,000 miles. My question is: should I replace differential fluids at 30,000 miles, 60,000 or 100,000 miles? I understand that replacing it now would not hurt, but does it necessary?

    Thanks.

    Interesting. Nobody can answer this seemingly simple question.

    In order to get the most accurate and write answer. You really need to send in an oil sample to a lab such as Blackstone.
    They will be able to analyze it, and give you a breakdown on the wear and recommend the change intervals.

    My personal opinion is that 32,000 miles is too soon.
    I would wait until at least 60,000 minimum.
    But if it gives you peace of mind change it sooner.

    If the manuals states 60k than thats when you should have it looked at. If you want to pay to have the fluid changed now, go for it, but its not an expense that needs to be made yet.
