Acetone Fuel Additive Update

Everyone seems to be making a scramble to supply "Top Teir" fuel. To conform to this standard, one of the qualifications is that the fuel contains no less than 5%, but no more than 10% alcohol by volume. Unless you *CAN* find the little out in nowhere fuel stations, you're going to be hard pressed to find a winter fuel formulation that does not contain at least a token amount of methyl in it. Good luck looking however! It's not impossible, just hard at first. In your quest, just casually glance the pumps over. They have to list the content of fuel on the pumps just like they have to display the octane levels. Worse comes to worse, ask someone in the store in a managing position the aclohol content/formulation of the fuel. But...don't be surprised if they don't know. Play nice and a little dumb, and you'll find your answers. :)

EDIT: Places that come to mind right away:

BP/Amoco "Amoco Ultimate" - their premium fuel is mega-refined water clear and contains no alcohol in winter. However, is it worth the cost, especially since in my own experience - premium fuel does not benefit the Chevy 4.3 6? I also experienced harder starts on premium fuel since it is a little prone to not ignite especially around freezing and lower. My truck will fire up, first touch of the key if in winter, it eats nothing but 87 regular unleaded.

On the opposite side of the spectrum, fuels/brands that contain a heavy dose of alcohol I have found to be amongst all of the other top-tier distributors. Especially "cheaper" fuel outlets. I will only say this much - avoid Walmart's "Murphy USA Stations" no matter the season. Out of desperation I filled up at one and it regretted it until I could find another station when I got to half a tank and topped off with a known good fuel.

From what I have been told, the acetone use should only be in the summer and not in the winter.

when do stations switch the gas back?

Mid April or so. You'll know when suddenly, the gas gage stays a little north of "Full" for longer than you get used to. :)

can't wait. i hate getting 13-14mpg.
