Thanks, unfortunately in my area the 3 NAPA auto parts stores that I knew all went out of biz. Will hafta get out the Yellow pages.Originally posted by WildeOne:<br /> Almost all NAPA stores have Deep Creep and Sea Foam. They're all over the place!
I wouldnt add anything to your fuel but Sea Foam and maybe a fuel stablizer, ( although I do not use a fuel stablizer). The only other thing I add to my fuel is GTA Fuel enhancer. Ive done plenty of research on the product and run a couple of tanks now and I have had increased performance and the engine just sounds smoother. I use 4 oz, per 14-15 gallons of 87 octane fuel.<br /><br /> GTA FUEL ENHANCEROriginally posted by GARY B:<br /> Well i give up ! Im going to spray some decard in my johnson 110 hp next weekend. A question does adding a bottle of card/injector cleaner into the gas tank do any harm to an outboard ?
