I have a 2000 Suzuki 1500 Intruder that has about 15,000 miles on it. I use MMO about every third gas fill up. I use Amsoil in the bike. Can I use MMO in the oil as well and not have a problem with the clutch? What benefits to the bike will I have by using MMO in the oil? Thanks in advance for any info......Steve

While Marvel Mystery Oil is compatible with synthetic, semi-synthetic and petroleum based oils, we do not recommend that it be used in motorcycles with a wet clutch.  Marvel Mystery Oil is such a good friction modifier that it could have an impact on the transmission and caused some shifting concerns.  However, you may want to look for a Suzuki chat room on line and see what other owners have done.
