Seems since Yamaha started recommending Ring Free to be added at every fill-up, adding de-carbon additives to OB fuel has become more popular.. I personally have never used any additives in my 2 cycle OB or Waverunners. I only use R-90 (100% gas, non-ethanol) in my OB , and run E-10 (gas station fuel) in the Waverunners. I do use stable prior to winter layup, but that's for only stabilizing the fuel.
Question: Am I the only one thinking de-carb not needed, are any you running 2 cycle engines using additives. Adding $15-$25 of oil at fill-up is bad enough, then adding another $10.00 of additive just hits me wrong. My tank is 70 gal, usually fill up when it approaches 1/4 tank, takes about 50 gals.
