So whys everyone use 75w90 when the S54 calls for 80w90?
As for the whole Royal Purple Synchromax thing, I think the issues are because people use the "manual transmission" version which is actually for manuals that call for ATF. Its a lot thinner and breaks down under heat easier. They do however make synchromax 75w90 (and 75w140 for all you that like to watch out for high temps) which I assume would be fine our cars.

Reline MT-90 is right, a lotta Mr2 guys swear by it. Personally, I just bought the cheap stuff. $5.99 a quart. Lol. I did however buy a quart of royal purple synchromax 75w140 to mix with it.

Then again, my car is missing the owner's manual so I've never seen what it specifies.  Either way, 75w-90 and 80w-90 are close enough. You'll never hear "You need a transmission rebuild since you were using 75 instead of 80." And most guys here on the boards and the MR2 guys have been running 75 long enough to prove that there are no harmful effects.
