I have up to 4 miles per gallon increase in gas mileage with the higher price since the epa took the pollution restrictions off the market. The sky looks really nice without the pollution gas. I went form sometimes as low as 16 miles per gallon to 22 miles per gallon. I usually got about 18 mpg so the the gain was 4 mpg. I do not drive in denver but the epa decided to penalize me for living within 50 miles of denver thus the bad gas.

I have read that the EPA required oxygenates are not good for mileage or performance. And of dubious benefit to the air.
