Do we really need to use "dri gas" anymore?
Years ago it was common to put a can of "dri gas" into the tank with each fill up to absorb any water that might have gotten into the fuel. After awhile we were told that the dri gas was added at the refinery to prevent problems in the delivery trucks and so it as not needed anymore. Now with the 10 percent ethanol we have in the gas is it really helpful or necessary for that matter to even use it at all? Lenny

Adding more ethanol to gas that already has a lot of ethanol in it doesn't help anything. In fact, one of the problems with modern ethanol-containing gas is that it will absorb moisture too easily. I still buy "Dry gas" additive, but I put it in my windshield wiper solution for better de-icing. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

I can't see why you'd need it at all since cars have a sealed fuel system these days. |

There is still some use for these. Older gas stations
frequently have moisture in their tanks and some gas is purposefully diluted by cheats. I remember my car stalling badly about 20 miles after tanking at an Indian reservation in New Mexico. Bad fuel was the culprit. |

Back in the dark ages when gas was leaded we siphoned some of the gas back into a glass jar -- proof that it was roughly 1/5 water. I think we added denatured alcohol, but I think it would have required a LOT of it, but maybe not. -- Cheers, Bev "We need to cut more slack for the stupid; after all, somebody has to populate the lower part of the bell curve." -- Dennis (evil) |

Water vapor can still get in as well as the amount that is already absorbed into the ethanol in the gas. Dri-Gas can be helpful if you are using gas that has been stored a while or that came from a store with low fuel sales. Or if you run straight gas without ethanol like I do in all the small engines and vehicles when possible. -- Steve W. |

Years ago if there was water in a car gas tank, a fifth of Whiskey poured into the tank, the alcohol molecules would 'cut' the water and allow the engine to run. That would depend on how much water was in the tank. |

There are valves in the fuel system to equalize tank pressure and the purge vapors from the charcoal canister. It's still a sealed system. |

It's still a sealed system. Air must enter the tank or it would collapse during fuel withdrawal. |
