On 85 octane (regular) I get around 180 miles to a tank (city driving) here but in Vegas for the same octane I was getting 220 miles to a tank. Maybe the altitude difference makes a difference in gas mileage. Generally, here I get 300 miles to a tank on 85 highway. I tested 87 octane (midgrade) here and I get 40 more miles highway (340 per tank). Hence, for an extra $1.50 I get 40 more miles highway, (cost of gas at the time $2.75) for a savings of $4.00...!
