Additives
Yes, I did say no additives. There is nothing better than clean, high quality fuel in a clean tank. Most every fuel contamination problem is related to water in the tank. It is virtually impossible to keep it out but occasional maintenance on the tank will get rid of it. Maintenance of the fill cap O ring will keep most water out. Running out of fuel (or pumping it out of the usual fuel line) does not get rid of the water on the bottom of the tank. An effort must be made to get the water out of the lowest point of the tank. I guess most of us like what's easy, sort of like a diet coke with a big mac. It doesn't work. Unfortunately most boat yards don't understand the problem nor do they know how to apply the remedy. There are many believers in additives. I've read posts that state "I've been using Brand X for five years and have never had a problem". Perhaps that was a water free tank that needed no additive. The fuel makers say that they put the right stuff in. The additive makers (all of them) say that you have to use their product. I know that too much of the wrong additive can cause problems. There is word that some additives react with other additives. I personally would rather play safe and keep my tank clean.
