FINALLY happy with my MPG! Last tank, 11.85 gallons filled up I went 439 mile for an average of 37mpg! This was possible due to the Ultragauge changing my driving style and actually knowing what works to get the best fuel economy.
Driving was mixed, about 85% highway at 60-65mph (less than ideal conditions, passenger, a/c occasionally, holiday luggage, traffic etc.) and 15% city. First complete tank driving with the ultragauge and I couldn't be happier! I can definitely improve my driving style to squeeze out a few more miles if I wanted.
