I'm currently running Mobil One Full Synthetic in the front and rear differentials. Any other brands I should consider? I've run Valvoline in other vehicles over the years with good luck. Am I missing anything? Thanks for any suggestions.
Differential oil 75w/90 recommendations please

If your Trailblazer sports an Eaton G80 "M-Locker" Rear Differential...You'd better drop in on THIS Thread and confirm that NO LUBRICANTS WITH LIMITED SLIP DIFF ADDITIVES SHOULD BE USED:

Limited Slip Additive needed for G80?
This is for the 2002 Chevy Trailblazer LTZ. Has the G80 with LSD and 3.73 gears (2wd). Does it need the additive or is Mobil 1 or Valvoline gear oils enough if they say "for LS"? 75w90 a good viscosity for it? Going to get a Fel-Pro gasket, I don't need RTV right? Thanks.

All gear oil come with lsd additive now ?
Back when I change out my diff fluid around 2013 . All gear oil bottle doesn’t say “ contain lsd additive “ now I note mobile 1 and Valvoline say that it contain lsd stuff . So I don’t need buy a small bottle of lsd any more ?

Really any good brand synth 75w90 is fine. Heard that Amzoil is the best but I never go into those boutique oils which are excessively priced.
Whatever you DO wind up "Putting inside of The Pumpkins" ...is going to be much better at BOTH ends of the SUV than whatever is inside of them ...Right Now... :>)

I ended up going with Valvoline Full synthetic 75w/90. It comes in the squeeze packs that make it really convenient to fill the diffs.
Thanks for all the suggestions.
