I did a search for this topic and couldn't find anything...could be my inept searching skills, so sorry if this has already been hashed out, but...
I am a member of a large Subaru message board, and a member there has what he calls a "Cocktail" of different fluids to use in place of a single gear oil in WRX manual transmissions. The idea is basically to mask certain poor shifting characteristics or create a bandaid fix for real syncro wear or damage.
I know the owner's manual states not to mix gear oils from different manufacturers; I assume this is because there is not miscibility standard with gear oil as there is with motor oil? Or is there really a cataclysmic chemical reaction that can occur?
Also, just for fun here is the cocktail recipe for you to know what I'm talking about:
1qt Redline lightweight shockproof
1qt Pennzoil Synchromesh
2qt Castrol HypoyC 80w-90
I think this is the latest evolution, anyway.
