Comments:
***?! In the last 1,000 miles or so, I changed the oil (0w40), the oil filter, the fuel filter and my wheel/tire combo. I know ...you're thinking that the wheels did it because I went baller for the summer. Nope. I went from 17's on 225/45-17 rubber to 16's on 205/55-16 tires. I saved unsprung weight! Haven't turned on the air, yet. Don't drive on the highway with the windows open. This is baffling.
