Why do they have winterblend

When do they start selling

Is everyone required to sell it

How much less mpg should I expect

Is every grade of gas from regular to premium altered to winterblend

Thanks for all the help

 

just as long as i got a full tank of gas idk

 

I found my answer to my question. Prepare to be educated

1. The gasoline pumps at my Chevron station say that the gasoline is oxygenated during the winter to reduce carbon monoxide emissions. What does "oxygenated" mean and why is this required?

"Oxygenated gasoline" is a mixture of conventional gasoline and one or more combustible liquids which contain oxygen ("oxygenates"). At present, ethanol is the most common oxygenate in the United States. The government requires gasoline to be oxygenated during the winter in areas that have a carbon monoxide pollution problem (cold weather and atmospheric inversions worsen carbon monoxide pollution). Oxygenated gasoline helps engines run leaner, which helps engines, particularly older engines, produce less carbon monoxide.

2. What oxygenates does Chevron use for oxygenated and reformulated gasoline?

Chevron only uses ethanol in its oxygenated gasolines

3. How can I tell if I'm getting gasoline blended with ethanol?

Most states require gasoline blended with significant quantities of ethanol to be labeled on the dispenser. Most winter oxygenated programs are administered county by county. For the winter oxygenated gasoline programs in the cities where Chevron markets, the seasons and counties currently required to receive winter oxygenated gasoline are:
Portland Oxy Season
11/1-2/29 Clackamas, Multnomah, and Washington counties
Reno Oxy Season
10/1-1/31 Washoe county
Las Vegas Oxy Season
10/1-2/29 Clark county
Phoenix Oxy Season
11/1-3/31 Maricopa county
Tucson Oxy Season
10/1-3/31 Pima county
Albuquerque Oxy Season
11/1-2/29 Bernalillo county
El Paso Oxy Season
10/1-3/319 El Paso county

4. Will using oxygenated gasoline reduce my gas mileage?

Oxygenated gasoline reduces fuel economy an average of 2%-3% because oxygenates contain less energy than non-oxygenated gasoline. Many other factors, like how well your car is maintained how you drive (such as speed of travel), traffic congestion, rain and snow, cold weather, and tire pressure can combine to impact mileage far more than oxygenated gasoline.

5. Can I use oxygenated gasoline in my lawnmower? How about my boat?

Our survey of the manufacturers of engines for non-automotive uses -- boats, garden tools, chain saws and snowmobiles -- indicates that oxygenated gasoline will perform satisfactorily in most later-model engines. However, some manufacturers expressed concerns about its use in older engines. The owner's manual is the most authoritative source of information about the fuel requirements of your equipment. If your equipment is older and the manual does not mention oxygenated gasoline, consult an authorized dealer.

 

so why have oxygenated gas a.k.a. wintergas? here in NYC we already get gas with 10% eythenol, so does that mean we have winter gas all year long? so regular gas becomes wintergas but forever?

 

yea cali has oxygenated gas year long too.

us carb states use it for emissions control year long

 

small engine motors require 85 octane gas anyways or some where around that octane rating
