I just got gas today for $1.92 a gallon for regular unleaded (87 octane). Lowest it has been for awhile. This is the first time checking gas mileage since changing the front sprocket to the 18 tooth. I have been using the trip odometer to gauge when to get gas, before the 18 tooth i had to switch to reserve anywhere from 115-125 miles, but never even took 3 gallons. Today hit 119 miles, took 2.4 gallons =49.58 mpg. I may have filled it a little fuller than last time, so actual mpg is probably over 50...not bad!
