Ravenol awd-torsen transfer case oil flush

[cuerna]

👋 Everyone

Have you guys use Ravenol torsen fluid instead of OEM G055145A2? Any issues with this oil?
I even found a website page claiming that Ravenol is better oil than OEM.
Ravenol is about $80 shipped a liter bottle versus OEM $105 (shopdap.com)

Hey! I used the Ravenol products from BlauAutoParts for all of my drivetrain fluid swaps at 60K. No issues in the 10K miles since!

Cool.. you used the transfer case oil too (ravenol awd-torsen)? or just front and rear Diferential.?

The original fluid is a GL4 with some other additives.

For the last 25,000+ miles (2.5+ years) I have been using Valvoline synthetic GL5 as it replaced GL4. No issues at all.

Back in 2020 I changed both diffs and the transfer case at 204,000 or so miles. Sorry for the sideways pic but this was the darkest of the 3 that came out of my car. Smelled like new fluid, just a bit darker than new.

Ok .I think I'll buy the Ravenol oil then and put it on my transfer case. For my rear and front diferrentials I used redline 75W-90
Thanks.

No need for special fluid if you're doing a drain and refill. ZF says unless you're installing a new center diff, you just need to use regular 75W-90. If you put a new center diff in, then yeah get the special Audi unicorn piss (Which is just 75W-90 with 4% Sturaco friction modifier) for $95/L or the Ravenol for however much it is.
