Use of dry gas

I would appreciate any experience/recommendations with the application of dry gas. We are able to buy gasoline on the street and fuel our boat at the transient dock. There is a fellow in our marina with a 100 gal tank in the bed of a pick up truck who graciously allows members to use it.

Thoughts about adding dry gas, and is so, how much? Our tanks hold 165 gals. each.

Thanks

Hopefully your using ethanol free gas from the car gasoline station, That's one thing that's is consistent with marina fuel whete I live is that is pure gasoline no ethanol. If you decide to use drygas the particular brand should list how much to use per gallon.

What type of gasoline are you planning on buying on the street.......if it already has ethanol, the dry gas ( alcohol or etc ) additive will not be needed. Do you burn lots of fuel or does the fuel in your tanks sit for long periods ( let's say two or three months or more ) ??

Now whether this is a good idea is another discussion.

We buy gas with 10% ethanol. The boat only sits for the winter months at which time we add Stabil.

You gotta watch out for symptoms that can go along with ethanol blended fuel. On older boats, fuel system hardware wasn't compatible with it. In all boats old and new, one of the biggest problems with ethanol blends is it's natural tendency to suck water out the air. The water eventually separates from the fuel and sinks to the bottom (phase separation). For this and other issues that alcohols can cause, it's best to try and stay away from ethanol.

The issue I have with these additives is that some literally claim to "remove" water from fuel which is a misleading statement and a whole lot of hype IMO. They don't remove water, they bind with water resulting in tiny droplets that are much easier for the engine to burn/run on safely. If you have a big water problem in your tank, these additives won't solve your problem.
