has anyone used ring free? i was told from a friend that used it, that since then his boat idles much smoother and the acceleration is better. does ring free just remove carbon build up?do you just add it to your tank of gas? is it safe to use on my motor? also can anyone use sythetic oils and do you have to drain the existing non synth oil before you fill it. by the way i have a 99 Mercury 115
