I'm new... just bought a 03' WRX. Anyway, my gear box is notchy... so I hunted for solutions and ended up finding a cocktail recomended by andrewtechautomotive.com. You all might have already heard of this 300 times..., but it was news to me. I read considerable amounts of threads backing this cocktail up. The cocktail is 3 qts Redline Light Weight Shockproof Oil and 1 qt Motul Gear 300 75W90. Anyway, I went in search of a local place to buy Motul Gear Oil.... and I found it!

I talked to a guy named Roger, who I believe is the Manager of the Parts dept. He said if this ended up being in high demand to PLEASE call him before you come so he can make sure he has some in stock.
Hope this helps. I know theres got to be others like me that want this cocktail and don't want to have to get it from some online source and wait for it.
Take it easy,
