Is "dry gas" really necessary?

The main purpose of 'dry gas' is to help prevent gas line freeze. When cold gas from a gas truck is transferred to the underground tanks at the fueling station, condensation can occur, and create water in the underground holding tank. The bottoms of the tanks are required to be pumped to remove this water.If you buy your fuel at a high volume station which pumps their tanks regularly as required by law, then you shouldn't have a problem...but if you get a bit of water in your tank, on a freezing day it will freeze in the fuel lines and stop the car.

Dry Gas does not allow water which has mixed with the gas to separate therefore the water will not settle out and freeze.

I have never had a problem or used 'dry gas'.. my brother who lives on the other side of town has had fuel line freeze 2 times in 4-5 years.. He now uses dry gas ..but won't change fuel stations...

I ask that same question myself I had motor problems a bad head on the motor. it would pop when I made a stop every so often. they experience mechanic told me until I change the engine. use dry gas so they would not be so many pops. and it worked. you would be surprised how much junk there is inside it gas. the dry gas will help remove moisture water and help keep your injectors clean by removing the junk. I use it not every fill up but every other or so especially in the wintertime. so by all means use it. it does help. and yes I finally changed my engine.

when something is in its Gas state it ceases to be a liquid so is always dry.
