Re: Merc, fuel additive question...
Man, that's a million dollar question. There are a lot of fuel additives out there and twice as many opinions to go along. Here's my knowledge/expierence: you want to stay away from carbon build-up. What happens is that carbon builds up under the piston rings and pushes them out and they eventually snag on the ports and break off, so you want a fuel additive that combats carbon build up. I have heard that Sea Foam, and Techron do an excellent job of keeping the rings clean, but that Yamaha Ring Free is the best there is. I do not have any strong opinion, and I am certainly not trying to advertise, but I do use Ring Free and haven't ever had a problem. Maybe coincidence, maybe not. I dunno the science behind it all, and I am no chemical engineer, but it seems to me that there is techron (which breaks down carbon) and other detergents in the gasoline already, so I am sure that helps a lot too. In the end, without extensive research, you are going by hearsay and opinion. If you find any facts, let me know, cause I am sure curious!!

But thanks for the heads up though I'll keep that in mind... thanks...
