How higher-octane gas could cut emissions and save billions of dollars

octaBelieve it or not it’s cheaper using high octane gas then regular, especially on long trips. The reason being is that you will get at least two more miles per gallon more than regular . 10 gallons regular, say $3.50 = $35.00 Premium  $3.70 X 10 = $37.00.  $2.00 more.  Miles gained 20. Most cars average 20 miles per gallon. You save one gallon at $3.50 gallon minus $2.00 more. Subtract the $3.50, you saved $1.50 per 10 gallons of gas and you get better car performance plus a cleaner engine. MORE
