Winter Gas Blend?

I've never heard the term used with Gasoline until i found TW. I think is a bunch of crap personally. I've had tanks near 20 mpg this winter and tanks near 16 mpg. When its warmer (over 40) is when i get closer to 20. When it is in the 20's and lower is when i get closer to 16.

I don't see how i could get nearly 20 mpg if the gasoline was what was causing the issues. Does anyone have any links to prove that there is a winder gas blend for gasoline or is this just a big urban myth.

My personal thoughts are that the air is much more dense when it is colder causing more air resistance. Also fuel doesn't' atomize as well at lower temps causing more fuel to be dumped in.

Maybe I'm wrong, but the winter blend doesn't make sense to me. Can someone point me to some real proof that a winter blend exists?

Try Google and why is this in 2nd Gen

and Niburu

 

Thanks Oz.

it goes in 2nd gen cause it will get the most attention there. Duh!

 

Not only a winter gas blend but there is also regonal gas blends for different parts of the country.I saw on the news this past week that there is over 30 different blends depending on where you live.All these special blends help drive up costs.We should only have two blends.Winter and Summer.

 

In Louisiana the "summer blend" costs more. There is a certain date range that they must sell the summer blend. I've never paid too much attention to the date and how my gas mileage changes.

 

even with the winter blend, i still see more of a correlation to my bad gas mileage with temperature than i do with the winter blend. If the article that Oz linked to is true, then we are using winter blend from middle of sept. through May. I didn't notice a change in my gas mileage until late November when it got cold. it just doesn't seem that the winter blend has as much of an effect as people think it does.

 

Colder air is more dense. Thus harder for your truck to push through.

 

Definitely do some searches. Whether you have no winter blend, just a winter blend in winter, or full year winter blend depends on where you life.

Just consider that it could be worse though, I live just outside of Houston and we get "winter blend" all year round. Most major metro areas get full year oxygenated fuel.

 

Same here. Its that Ethanol in gasoline. Temperature changes its viscosity so it burns like crap.
