After some research I believe I have narrowed down the 2 possible causes of my less than average MPG.
2013 LT 1.4L
1. How do I check for brake drag? Just jack up the front end, put it in neutral, and spin the front tires?
2. How can I for sure know if the O2 Sensors are a culprit? I am a little over 80,000 miles and read some people change them at 100k. No check engine light at this time.
3. I keep my tires at the manufacturer recommendations. I read in the MPG thread from Xtreme that putting them to the max can give better gas mileage. Is it worth putting the to the Max PSI?
Thanks guys!
