Does anybody heard of this product? I just bought it in about 2 months ago for my 15hp merc 2-stroke, 25hp, and 60hp merc 4-stroke EFI. I had been using it for a awhile and all my my motors seems to run alot better than before and runs smoother. Before I add a gas-shok on my 60hp merc 4-stroke and my motor seems little bit shaky and burns more fuel than before. For the last 2 months, I had been using a gas-shok on my 60hp merc 4-stroke and made a big difference in gas milage, alot smoother operation like a brand new motor with 1 hour on it. I had been using a star-thron, sea-foam, sta-bil marine treatment and none of them works as good like Gas-shok because it has no Alcohol in it like the other one has alochol. I recommend this product to anyone who like to try one. here's the website www.usafuelservice.com
I have been using it for almost a year now. I had some fuel issues with my 25 merc 4/s and a local marina tech turned me on to it. There have been no negatives yet (knock on wood). Only easier starting, cleaner burning and all around better performance! Now let's hope I didn't just jinks myself!
I haven't tried that, but this seems to work well for me, Quickshot: http://www.amsoil.com/storefront/aqs.aspx
