Well here in Raleigh we have had to use "Oxygenated" gas between Nov 1 and Feb 29 since the early 90's to ease pollution. Here is a link to some info on it

I don't see Charlotte on there so the mechanic may be talking

I have always noticed an increased roughness when using this fuel and also a decrease in mpg.

Actually on reading this

I think Charlotte is included too

 

I did not see Union Cty. listed which is where I live, and subsequently buy gas. I mentioned in the other post that I buy gas at the same station about 90% of the time in-town, because they have a 96 oct. premium. However, the Service guy does not know this. Could there really be that much difference in the seasonal gas here since its such a mild climate, versus, say North Dakota? I'm curious because bottom line I want to know what caused the mis-fire be it gas or another problem.

 

There was a big flap about winter gasoline blends out west when I lived in California in the early 90s. There was a study of pollution output in (I think) Denver, CO. Oxygenated fuels do cause fewer hydrocarbons to be released for every gallon burned. But, the study found that the amount of pollution in the air was UNCHANGED. Why? Because oxygenated fuels typically get ~10% worse gas mileage. Thus, the extra fuel being burned balanced out the so-called pollution "savings".

Another example of knee-jerk environmental policy. If they'd taken the time to look at the science, they'd have realized there was no benefit in mandating a different fuel formulation.

Note, this was almost 10 years ago. Formulas may have changed, and there may be a real benefit now. But back then, there wasn't.
