I'm looking to change the front and rear differential oil in my 2015 Chevrolet Suburban LT. However, I'm seeing a lot of different part numbers in oil types, which is confusing.
I went to several stores, but none of them had ACDelco 75W-85 for the rear axle—only 75W-90. I'm uploading an image to ask: is this the correct oil I'm supposed to use?
From what I understand, I need ACDelco 75W-85 and 75W-90—correct?
While searching for 75W-85, I mostly find ACDelco products listed by part numbers, but they don't clearly state the viscosity (75W-85). In some cases, when I do find one labeled 75W-85, the compatibility checker says it's not compatible with a 2015 Chevrolet Suburban LT.
The oil shown in the attached image is the only one I found that clearly says 75W-85. Everything else I’ve seen online is listed only by part number.
I'm up to my cabeza trying to find the correct oil..
