1). Has anyone used the BG 44K Fuel System Cleaner in your outboard engine? If so, how was it? It's supposed to be great for cleaning car's fuel injector.
2). Has anyone used Yamaha Ring Free and Mercury Quickleen at the same time? I heard Qucikleen is better for the injector and the Ring Free is good with carbon control (in general) and that they can be used together.
Thanks.
