Re: Re: MPG better in summer?

That makes sense, thanks for the explanation. I always keep a good eye on maintenance but I don't always gauge my tires. Good call.

MPG better in summer?

I have a 2000 Chevrolet Cavalier and a long commute. I have noticed I get 30-32mpg when the weather is warmer and only 27 - 29 when the weather is colder. No change in driving style, can this just be temperature related? I have been told the gas formulation in summer is different from winter, is that true and would it make that big of a difference?
