Transfer Case and Differential oil change

[Teodoro Basura]

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..

I don't care about the brand.. I just want to get the oil.

I found this oil that is supposed to be for Suburban 2015.

Is this correct..? 

I have to get the 75w-90 too..
