No problems putting it in the tank though, just don't put it in your intake/vacuum lines/oil!
Use the highest quality, largest filter you can run on your bike, that'll be the best protection for your oil/engine. Not sure what bike you have, for most Jap bikes, in order of filtering ability, Amsoil EA15K13 "long" if you can fit 3.35" filter or EA15K12 if you can't, Purolator PureOne PL14610 "long" if you can fit 3.5", PL14612 if you can't, Baldwin Premium B1402 "long" 3.5".
