Automotive Dry Gas additive

[PAkev]

Upon reading some of the posts in the boating section I've seen a few posts and replys about fuel water seperators. It is my understanding that Dry Gas additive also removes water and or condensation from the fuel system. I have a fuel water seperator on my Duramax Diesel truck so the fuel lines don't freeze up in the winter but have never seen it on gas automobile engines. The major difference I can see is that cars get used every day whereas the boat may sit for days, weeks, or months at a time to enable condensation. Is dry gas indeed an alternative to a fuel water seperator or am I missing the mark with something more important?

A water seperator is definately not needed in a car. Boats are allways in a damp environment and often filled on the water, so there's alot more chance for water to get in the tank. Drygas is just isopropyl alcohol, most areas of the country have 10% alcohol in their gas for several months of the year, if not year round. This means drygas is a complete and total waste of money.

It's got nothing to do with freezing fuel lines, water plays havoc with a diesel injector also fungus lives in water and feeds of diesel, this can plug the filter and/or injectors.<br /><br />Water seperators are crucial in diesel applications.<br /><br />Aldo

Re: Automotive Dry Gas additive

This only applies to gas engines:<br />Water in your fuel tank (condensation, or rain water bleeding in, etc)does not mix with gas(a light oil).<br />Water is heavier than oil.Will seperate and lie at the bottom of your tank. Right where your fuel line pickup is.<br />Alcohol molecules will attract gas at one end, and water at the other end.<br />Alcohol (drygas) will take care of a little dampness. <br />Too much water, and you should have a water seperator.<br /> Be happy, enjoy life and boat lots.
