who uses fuel additives?

[RX-1MAN]

I've always used Marvel Mystery oil in my touring motorcycle every third tank or so. I am considering putting it in my four stroke sled. Anyone use this or a similar product in the gas tank?

For what reason?

I use it in my nitro methane R/C truck as after run oil for storage. I don't think I would run it in my sled however. It's also very thin and work great as a bolt remove due to it's great wicking action. doug

Many owners of the Suzuki Cavalcade use it in their gas and some even in their oil. After 85,000 miles and the motor never being apart I sure don't think it hurt my bike any. I plan on keeping the RX-1 at least until my first valve clearance check is due(unless Yamaha comes out with something really new).
