I live a little more than 100 miles from Maple Grove Raceway. I decided to go yesterday and sell some stuff. I had my 2,200 lb trailer and just over 1,500 lbs on it. I have never gotten better then 12 mpg hauling the trailer empty going there or coming back empty without even stopping. I did have a half an hour of stop and go traffic that I only went 1 mile. I came back with a little under 1,000 lbs on the trailer and the 2,200 lb trailer. I went to fill up and went 213.2 miles. When I was done pumping off it said 15.950 gallons. For a mpg of 13.3667.
I still think I could do better because it was TC locked the whole way there and on the way back it said D5. Why is that? The lie o meter is way off before it would say like 14 or 15 and get like 10-11 and now I'm getting 13 and the lie o meter said 23-26 most of the way at the pump it said 26.3. I would say when pulling right now I'm going to get about 100 miles more per fill up. And at just over $4.00 a gallon I would say every 5th gallon is free.
