Not looking to debate which manufacturer has the best Gear Lube,
Just trying to figure out which MOPAR Gear Lube is correct for a 2019 Charger Hellcat.
Owners Manual specs 75W85 (API GL-5), but is it P/N 68083381AA or 68210057AB?
Can't figure out what the difference is.
Thanks!

68083381AA has the LSD additive mixed in 68210057AB does not.

List price $56.50 and you need two quarts, that's nuts.

Grab some Royal Purple 75W-90 for $20 per quart and you're good.

That is nuts!
But how does 2 for $29.91 sound?

Wrong kind.

Also, I did 1 qt and 4oz of the friction modifier, so you don’t need 2qts if you do that.

Bingo! I figured if I needed more, I'd use an ounce or two of old stuff.

It's exactly what Owners Manual specs....
MOPAR Synthetic Gear Lubricant SAE 75W85 (API GL-5).
How is that wrong?

Wrong part number, that’s for non ZF diffs.

I can't see the part number on my phone but maybe all it needs is the bottle of the LSD additive?

ZF has “special” fluid for its clutch packs. I can confirm it smells like awful BO

 

[Unholy707]

I just changed it diff fluid a few weeks ago, I told parts counter my car and they handed me the stuff and it says in it “for ZF differentials”

Right and if the Jeep is E-Locker it won't need the additive but the ZF definitely does.

It's the correct fluid. You just need the additive.

I remember when the Chevy dealer parts guy told me i need the new GM LSD Gear Oil (which already contains additive) for my C5, not the one spec'd in owners manual (additive needed) that I've been using for 10 yrs. Long story short....everytime I started from a red light, my tires were spinning! Had to drain & changed it back to Manufacturers spec.

A bit different here, but ok. Are you putting non ZF trans fluid in your a8 too?
