Right on the money. I’ve now done two trips from New York City to DC. Slowing down significantly and using cruise control the entire way changed my half tank range from 165 miles to 220 miles. For a Wrangler, that’s nothing short of phenomenal, nearly 25mpg as compared to the previous 18mpg.
It really doesn’t impact on other drivers either. For the most part, 65mph is the speed limit on I-95 anyway and there are enough lanes for all the speeders to not even notice me. What I found really interesting is that when I slowed down, several other cars did as well – falling in line behind me for miles. Maybe they were just looking for an excuse to drive slow without looking ‘weak’ on the highway.
