Thread: How much diff Oil

  1. #1

    Default How much diff Oil

    I have 135KM on my honda crv and never changed the diff oil. Should I change the diff oil or should I wait till time comes to change. I asked my mechanic and he said rear differential oil does not need to change, but i want he said it needs 3 ltr. But on internet i found it needs around 1-2 ltr. So how much exactly diff oil needed.

    I trust your mechanic.

    Break down in terms 135Km and 3 ltr?

    The rear diff, is noted in your owners manual time and time again we ignore the info that is right in front of us, if it was digitally printed I bet we pay more attention?

    1 qt and 1 ounce is the required rear diff change, you do not have to add that extra ounce.

    the milage is based on todays habits. up to 30,ooo miles, used to be 60,000 miles.

    Some will change less and some will neve rknow they had a rear diff....

    never insulting

    How frequently you need to change the Dual Pump Fluid in the rear differential depends a little on what year your CR-V is.

    1st and 2nd Gen CR-Vs can go about 30,000 miles (~48,000 kms) between changes, but newer CR-Vs need to have their Dual Pump Fluid changed more often.

    I believe the official amount is 1 liter, which is just over 1 US quart.

    My guess is that your mechanic is not familiar with Honda's RT4WD system used in the CR-V, and thinks that the rear differential is just a normal differential that takes gear oil, and not the special Honda Dual Pump Fluid required by your CR-V.

    Good luck.

    Find a new mechanic.

    ALL fluids wear out over time.

    Ask a Jeep Cherokee owner what happens when they don't change the fluid in that Dana rear diff with limited slip. Even worse, just for fun, try calling every salvage yard you can get a number for and ask if they have a used Jeep rear end for sale. If you actually find one, they will want NEW price for the used one!

    Change the fluid. Drain it. Fill it. That's it.
    Buy 3 quarts of fluid so you have enough to do 2 changes. The fluid won't go bad sitting in the closed up container.

    when you do the change, you want to make sure you get enough in, and sometimes that hose will slip out why I have an extra container, just in case.

    Yesterday I knew my diff was not the issue, so I had 1 container, I drained 75% out, capped it and poured the container in, some did miss and that is why isay have more than less

    It takes again what is noted in your Owners manual BACK page
