Should I buy the 'proper' differential fluid for fricking $100 a liter or buy this instead?

Should I buy the 'proper' differential fluid for fricking $100 a liter or buy this instead? For my car BMW recommends this

Front: Hypoid Axle Oil G2 (83-22-2-413-511) (SAE 75W-85)
Rear : Hypoid Axle Oil G3 (83-22-2-413-512) (SAE 70W-80)

and pic related is a fraction of the price but doesnt match the ratings (75w-90 vs the other 2)... I figure its probably close enough though. Is this a bad idea? y/n

      With engine oil there's some sway room, 0w-30 vs 5w-40 etc, why wouldn't it be the same for the differential? Or do you mean something else?

    Go for it, OP
    What's 5 or 10 oil weight difference anyways? It's not like anything bad could happen, BMW is just being greedy.
    And by being a BMW owner, that means you're both smart and rich enough to know better.

      I read a horror story on a forum where some guy did this and said his diff was clacking when turning the car, so that's why I want to use the proper viscosity, but then again a difference of 5 shouldn't really amount to shit in the first place

        Some have friction modifiers that make them special.

          Wouldn't that kind of thing be regulated under the specifications? Like GL-5

            Nope it’s an entirely bmw thing for their high dollar diffs, your probably isn’t being an x5 but just be aware that they do truly shit like that.

            homie it says "GL-5" right on the BMW bottles. It is not special.

    For straight diff it probably doesn’t matter but if you have some fancy LSD they have very specific tolerances for the oil.

    Stop being a BMW autist and put in some Redline fluid. I use redline for all my drivetrain fluids and its fine. There is no special additive in the OEM fluid that makes it worth $50 a quart.

      Aight bud I found this. It's a perfect match for the front and ehh close enough for the rear. Literally can't find 70w80 anywhere so frick BMW for calling for a unique blend. I'll pay an extra $8/L for this but hell to the naw for the $120/L they want for the rear

      Also I'm going to assume O'Reilly is wrong when they say this doesn't 'fit' my bmw

    Get the Liqui Moly equivalent. Made in Germany. I’ve ran that stuff for years in me E92 with no issues.
    Yeah don’t get that Valvoline stuff, it’s made by mouth breathing ameritards for their shitty “muscle” cars.

    After having dealt with a Jeep and its Vari-Lock diffs I think where you could have problems is if the limited slip additive in the cheaper stuff doesn't get along with the diff clutch friction materials which results in chattering and odd squealing noises on turns. Assuming the diffs are actually limited slip of course. If they're not then you'll never notice that the lube is slightly thicker at temp.

    If you don't have an lsd that valvoline shit will frick up your diff as it contains friction modifiers for lsd's.

      it's the other way round. non lsd oil in lsd = more chattering and more wear

    unless it's got an lsd I just put 90w in them.
    only clutch lsd needs special fluid.

    this is why so many used BMWs are clapped out, moronic owners that buy them and can't afford them cheap out on maintenance treating them like their last car (toyota). like dude it's a $50 difference. if you can't afford an extra $50 for a 60k mile service then you should have stuck with the toyota.

    Its beyond fine. The fact that you even bothered to change diff fluid means it will last 5X longer than the average moron
