My buddy insists dry gas is no longer needed with modern gasoline. If that’s true, why would they still sell it in stores?

He maybe thinking gasoline with ethanol, which i think is basically what these additives are. I don't believe they are needed in that case. Ethanol free gas, i would think, could still benefit.

 

I don't understand the previous post but no doubt dry gas is still needed.It removes water,which can be a problem in ethanol blended gas.

 

your friend is right.
dry gas was more of a necessity when gasoline didn't have the additives they have in them now- and, mostly in older cars with untreated metal gas tanks- which were prone to condensation in colder climates- where water would settle to the bottom of the tanks.

not so much an issue with modern vehicles- most of which have insulated, treated tanks and modern gasoline that has hygroscopic (ethanol / methanol) additives added to it.

 

My apologies. I was trying to type it out quickly.

I Believe you have it reversed. The additives like dry gas only adds alcohol. Ethanol is a type of alcohol. Adding more wont really help. In gasoline sans-ethonal it does help but, I would only add during rapid temp changes and when it sits an extended period of time. long term use will do damage to fuel lines.
