Audi wants $125 for one liter of the referenced fluid, part #G 055 145 A2.
Some service documentation from ZF says it is 75W90 Gear oil that contains 4% of Sturaco FM 1992-KS.
Ravenol sells an exact replacement for this fluid, but they want $65. BG, Chevron and Motul are recommending a 75W90 gear oil w/LSD additive, but Amsoil and Valvoline are recommending a GL-4 75W90 MT oil. Redline's recommending D4 ATF, but I think that's an error so I reached out for further assistance.

Looking for guidance since the owner doesn't want to spend $125 for a liter of fluid on a 15 year old Audi, if possible.
Thanks.
