I bought it from a distributor is 1 qt bottles. Had to buy a 12 qt case, but since I figure on changing my gear oil every 15K miles, it won't be an excessive amount. We'll see how it works in my 2005 Subaru Legacy GT transaxle.
It is truly an excellent oil, you guys are very lucky to get it there, can't get it here and I need it desperately due to a ancient design over worked 3 speed on one of my vehicles.
