This trip is about forty miles. A mix of urban/suburban and freeway. Just got the car this afternoon. Factory inflation. Just wanted to see what it would do. 60mph on freeway, speed limit off freeway.
Note: yesterday's and today's mpg per the dash display. Same weather, mid 60's. No wind either day. Today, I set the tires at 40/38 and installed a lower grille block. Temps ranged from 186-195. Same speeds. Maybe my foot's a little more educated.
