Hey guys, I have been hearing about winter gasoline sucking or whatever and summer gas being better. Does anyone know why this is? My sister and I were talking about it, she likes to complain and argue, and I couldnt think of any reasoning to why it was better. I have heard you get better performance and better MPG with summer gas but why?

It's true, in summer there are more cars driving, which means more emissions, which means they need to sell cleaner gas to keep the feds happy.

Shoot you reminded me, I need to change the summer air in my tires to winter air.

Not before you change your muffler bearings and blinker fluid young man, you know how important maintenance is!

My understanding, and this may be way off the mark, is that in the winter with colder air cars produce more emissions than they would in warmer weather. I know that to aleviate this problem at least in New Mexico and Colorado, they add ethanol to the gas, and I get crappy gas milage from that day until the day in spring when they take it out. I guess the poor fuel economy could be because I have colder air in my tires I guess and so the pressure is down, maybe I'll check that. anyway just thinking outloud again
Happy holidays guys

Just change the air in your tires to winter air and you'll get your mileage back.

ok, for real,

in the summer the refineries ad extra "ingredients" to keep the gasoline from evaporating in the heat, since raw gasoline will evaporate at as little as 65* after Katrina and all the other hurricanes that didnt effect crap,

they stopped adding these "extra" things to speed the rifinery production, there is also the oxigynator agents, spelling

anyway, ethanol, aka corn alcohol is used in the midwest i used to know what those weird chemicals they added at west and down south but i forget

but "winter gas" is straight run gasoline with very little additives

All gas stations change gas from season to season. If you have the summer gas in the winter when it is very cold, your car/truck will not start good at all. The winter gas helps this but isn't good for emissions in the summer.

I have a Bmw K100 motorcycle, in the winter short town trips it uses more fuel because the mixture is richer ie. cold engine with electronic injection runs very rich, on long runs, the fuel consumption is the same all year round.

Yknow, I've never noticed a difference in mileage on the bike during the different seasons, but maybe that just means I don't do enough cold weather riding.

Ya there is also the fact the in some parts of Canada and all of Alaska the temp changes 80+ degree from summer to winter.

Try starting a car at -75 degree with summer fuel..The damn gas will almost gel on you with the additives in it. In the winter they use diesel at the oilsand plants that burns 40 to 50 times hotter then the jet fuel use in a fighter. They use it their heavy haul trucks.

They add ethanol or an equivalent here during the winter, just read the notice on the gas pump wa4x4. Gas mileage in the Eclipse loses almost 2mpg during the winter.

Na, just means I don't have rain gear. I don't need no brain......get it?

wa4x4 · « **Reply #20 on:** Dec 22, 2005, 11:59:06 PM »

The gas station I go to has no notices and I got a new car this winter, so I don't know if it is losing anything because of the gas.

Actually, this is good to know. Hey Glen, I did not know that.

Nate, my best mileage was 63 MPG back in the summer on the GS500E, and I could average at least 50, but since then, I have not gotten over 50 MPG at all.. So I guess Carbs run a bit rich with colder weather too

Well, another thing, colder air is of course more dense, so it can hold more parts of oxygen per cubic unit. So typically, the chance of detonation decreased with the decrease in intake temperature, so they dont have to have as great of gas in order for an engine to run properly.

they dont have to refine it as much, so its actually cheaper for them to make, so prices should come down not go up

hey Mikey whats gasoline cost over yonder

It also make more horsepower...

Well it is true, motors run better on colder days, the air is more dense.

Thats why water/meth injection is KING!!!

kyle_22r · « **Reply #26 on:** Dec 24, 2005, 10:16:04 AM »

i'm pretty sure winter gas here is oxygenated. i always notice an abrupt drop in mileage at a certain time every fall, and then an increase in the spring all of a sudden.

So that's how mike keeps up with his hectic schedule, meth injection! Secret's out bud!
