Cold Weather Gas Tank Additive

you don,t need any, BUT I use sea foam it cleans the gunk out of the jets ,and kills any drops of water you mite have.

None. Not needed.

Will you be sitting for that time? If so, add Stabil to the gas because of the ethanol. Being from Michigan, we did nothing other than buy our gas. No additives that we ever added to our tanks. We were driving our vehicles on a regular basis though.

Nothing gas company make a winter blend

In the older days we would add Dri-Gas to prevent freezing gas lines. Most gas available today is already 10% alcohol which is what Dri-Gas was.

If it is a gaser then you need do nothing. Refineries add lighter components in winter, the main reason you get less MPG.

When in Colorado, check the local filling stations, as fuel companies use additives to the fuel in the winter months.
