So you know up until recently I worked at a huge marina that sold Honda, Mercury opti and verado, Evinrude, Suzuki, and Yammie,,,,,,in every brand of motor the best additive that we found for keeping the fuel stablized, no carbon build up, octane regulated, and a problem free fuel system was literally the Evinrude 2+4 FUEL CONDITIONER….unlike the other brands of additives like Merc and Stabil it has NO Shelf Life, is more concentrated and really gives better results…..if you can find a bigger BRP dealer they should have it in 50gallon drums for way less money……Just a FYI statement, dont want to start my brand is better than your brand……BrannonYour Signature …
