My 2018 Audi SQ5 is due for fluid changes of the drivetrain. I'm wondering what is the recommended fluid for the ZF 8? VAG-branded is stupid expensive, so I'm already considering just using ZF's own Lifeguard 8, which is probably exactly the same oil. I'm not asking for the cheapest oil, but when you have OEM prices this high, usually there is a cheaper product that is actually better than the OEM. Curious if that is the case with the ZF 8 transmission.
