I'm right at 100K miles. My clutch has been slipping under acceleration for the past 15K and I have the money in hand to replace it. I have not bled the MC and I am using Mobil 1 synthetic, so that probably isn't helping. I plan to continue using Mobil 1, my question is what do I need to replace and are there certain brands to go with or stay away from? I'm assuming plates and springs, what about the basket. I'm mechanically inclined but have never done a clutch.
