Lets hope this doesn't turn into a flame fest... For most of it's life I ran Mobil1 gold cap in my 00 426 and was happy with it. I've been running it in my 06 and I'm having issues with a grabby clutch even though the clutch appears to be fine, so I'm looking to try something different. My first thought was to go with Amsoil, until the local dealer told me it was $10 a quart But if it's really worth spending the $ I will. My question- is there another less expensive oil I can pick up at somewhere like Napa that will perform well? I live in a small town so my choices are somewhat limited, but I'm sure they have some type of MC specific oil. I'm hoping to stop by on my way home tonight and see what's available before springing for a quart of Amsoil.
