My last tankful was 74MPG, but I was really trying hard to burn off the last 1/2 tank of gas to get a fresh fill in for winter storage. Frankly, running WOT and in lower gears to keep the RPMs up still didn't cut into the mileage like I was hoping, but it was an interesting experiment. Its hard to calculate mileage on something I only fill up every few months, so it'll probably take an entire season to drain a tank if I putt around slow and quiet like I usually do when running errands in town.
