The caravan is finally over 177,000 miles.
214.7 miles / 10.185 gallons = 21.08 mpg
I'm surprised I was able to achieve 21 mpg considering I had the air conditioner turned on a few times. It was very humid outside for about 3 weeks. This was with 89 octane (10% ethanol). The next gas update will be with 87 octane (no ethanol). Check back for the results.
Caravan odometer = 177,293 miles
