so that it keeps gas prices down during these 2 hurricaines.

That means cars less likely to detonate.......

what is done to winterize gas?

they put it in the freezer!!!

gasoline popsiculs. COOoooOOL!

They usually add *I think* ethanol or methanol to it. Helps to keep it from freezing up here in the tundra. Next time I fill up, I'll look at the signs.

LIAR!!!!! :)

:(

that means I'm going to have to be adding that shit myself then.

Winterized gasoline is oxygenated usually with ethanol since the formerly preffered oxygenate MTBE was removed having been found to harm fish. The only reason it's oxygenated is that it helps old cars produce less carbon monoxide. For everything that has an oxygen sensor and runs properly it helps very little and tends to reduce fuel economy in everything.

who cares. as long as its cheap and it works im buying it.

Winter gas also typically involves increasing the proportion of a viscous component in the Deposit Control Additive (DCA). compounds that supposedly help prevent intake valves sticking during cold starts. Of course the valve doesn't remain shut, but it doesn't open as smoothly as it's supposed to and puts added pressure on the valve guides and cam lobes. Intake valve sticking also causes low compression, which leads to hard starting, start-up “roughness,” and poor low temperature driveability.

Of course for those driving rotaries in winter, valve sticking is not an issue.

Winter Gas usually also has an amount of gasline antifreeze premixed to prevent ice pellets from forming in your fuel filter, which can lead to fuel starvation during cold starts.

It also evaporates more rapidly than summer gas, leading to easier vaporization in ultracold intake air charges.

They oxygentate the gas in the winter. This can lead to a leaner mixer which may make a turbo'd car like the RX7 more prone to detonation.

I lost more engines in the winter. Of course it's impacted with a colder air temp.
