Who conducts the fuel efficiency tests for vehicles in the US? Is it the manufacturer, or some independent agency?
Whoever it is, I am very surprised that their result for my vehicle is more conservative than reality.
Officially, my Honda Accord 2002's highway MPG is 28. This weekend, I measured 32.48 MPG, with a sample size of 414.4 miles of highway driving (with a few miles of it in a city)—and that's with my headlights on and my laptop plugged into the cigarette lighter through an 12v-120v inverter!
Does anyone have similar (or opposite) experiences?
I'm sure they average it all out, and the way you drive makes a pretty big difference - how hard you accelerate, when you come to a stop, whether your tires are filled up all the way, etc.
Also, have you considered using Disqus for comments? Took me like 10 minutes to figure out a login I could use. Plus, I won't be notified if you reply to this, so I'll never see your response.
