'12 Jku MPG analysis 36k miles
I've updated my mpg charts to include the data up to 36000 miles. It's a 2012 JKU sport with manual trans and 3.73 rear. I made two charts. One with all data including towing my toyhauler and one with the towing data stripped out. One thing I plan to do is make a histogram of MPG grouped by month of gas purchase. This may help to provide real numbers to the effect of temperature and winter blends. As I've said before, the data shows that you cannot make a judgement of how a particular mod affects mpg unless you look at data at least over several tankfuls. My only mod is that I put on rubi tires instead of sport. All fluids are also synthetic.

It will be interesting in a few months to look at the data again. At 29,000 I changed the factory manual trans fluid and the transfer case fluid. Looks like higher MPG since then, but there was at least 1000 miles of mostly highway due to a couple of trips.
