My vans mpg numbers are down. No doubt gaining almost 1,000 lbs
Last 3 results are 15.86, 18.02 & 15.52 mpg (US). The 18.02 anomaly is most likely due to fueling up once at a full serve pump. I almost always go to self serve and "top off" when refueling. Also, the following 15.52 mpg result would be caused by the the less than topped off tank previously.
I lost all my previous records when I upgraded the app I use to track mpg. My previous average was 17 mpg consistently. My current average is 16.29 mpg. I started recording the data on my iPod and also in a spreadsheet now.
I think having the bikes extended approximately 2 feet back from the rear doors of my van is acting a bit like a parachute and that would affect mpg and I am fully loaded with "stuff" in the van right now so it is heavier than ever before.
