Rated 5 out of 5 by 4 reviewers.
Rated 5 out of 5 by Best in Class This product does what many others only claim to do. With all the concerns over fuel containing ethanol, I wouldn't be without it. I put it in every other or, every third tank of fuel. I also use Sta-bil in every tank. My engines (75 hp Merc.) fuel system stays clean and purrs like a kitten! Spark plugs stay like new even after two or more seasons of frequent use. The engine is a 2001 and only routine maintenance has ever been needed. March 27, 2014
Rated 5 out of 5 by Best Product on the market I wouldn't be without this Engine additive. It keeps my Mercury in good running condition and keeps the carbon from building up in the Engine. It's an additive I would recommend to any Mercury owner. December 13, 2013
