Getting ready to replace all the fluids in my 2012 Suburban with 135k miles. Was planning on doing 75w90 gear oil in both diffs.

Can anyone tell a difference between these two other than the size container?


ACDelco 10-4099 75W-90 Gear Oil - 1 gal https://www.amazon.com/dp/B06Y5JNF9Z/ref=cm_sw_r_cp_tai_KqMbFb5H69Q37


ACDelco 10-4016 75W-90 Synthetic Axle Gear Oil - 32 oz https://www.amazon.com/dp/B000QGOX1A/ref=cm_sw_r_cp_tai_trMbFbG9W93V9

I can’t see any difference. They both even have the new grape scent that is all the rage in gear oils as well!

Those look like what we call hills around here.:p
Here's a pic of mountains, it was a few years ago when I was running 26's on The Beast and it had a different look lol. I was at about 6000 feet elevation and that's Mt Hood in the background. This area gets about 10-12' of snow in the Winter.

Nice shot! Haha. That’s what I was thinking when I saw the pic. I’m used to the Colorado Rockies. [emoji631][emoji106][emoji16]
