Hi, guys & gals. Has anyone used the AMSOil Manual Synchro Transmission fluid, MTF 5W-30? I'm about to put my rebuilt A543 into my car and will soon need some top-quality oil. This AMSOil stuff is $15 a quart, but I'll need less than 3 quarts for the gearbox so the cost is not a big issue. Is this any good? Is there anything better? Thoughts, please!
