I noticed that close to, if not after the 36,000 milestone, around the same time I replaced the crappy stock tires with some Good Year Wrangler Silent Armors. I noticed a significant drop in my average fuel economy, about 2-3 MPG less than previously. This drop was also right before I had a "Reduced Engine Power" warning/Check Engine light at 38,000, and a dealer replaced my throttle body sensor. I'm still noticing lower fuel economy. No clue what this is caused by or how to fix this problem.
