A little background, I've driven maybe 100,000 miles in my life. It's a high estimate, but realistic. Many of those on the highway. Given my van gets like 22-23 miles per gallon and gas has cost $3-4 the last six years, we're looking at a minimum of about $13,000 in gas in my driving life. I like to imagine that I am a somewhat frugal, conservative person and my driving habits reflect my physics knowledge, in other words conservation of momentum and the high cost of acceleration. So I have learned to drive so that I get the best mileage. On this trip I am the only drive due to the insurance policy.
A few simple way to get better mileage:
- Take weight out of the vehicle, example: most of the time I take the middle seat out of my van.
- Pump up the tires, just watch out you don't over inflate them too much.
- Turn down the air conditioning.
- Accelerate slowly, don't race out of stop lights!
- Coast instead of breaking, an extra 5 or 10 or 20 seconds per stop light or stop sign coasting will save more fuel.
- Drive 55 miles per hour, which is really only convenient when the speed limit is 55, and it is in central Louisiana all over the place.
- Drive on flat roads or downhill, and once again central Louisiana is very flat.
- Fly around curves, because breaking a whole lot then speeding up again on a curve recommended only 10 mph below the speed limit is a drain on fuel.
That's about all I can think of. Combined, assuming the trip odometer was at 0 when we started, and there was no way it could have been more than about 25, we still averaged way above the stated 33 mpg for a Nissan Rogue on the highway. I don't track my mileage normally, aside from weekly to know how much I drive per week. So I really have no idea if my hypermiling does much good in my daily life, but the last two days it managed to be incredible. Moral of the story is, I think, I have learned to do hypermiling. Achieving 37 mpg in a crossover, I didn't think I could do that. Of course, a 14% mileage improvement doesn't compare to people getting more than a 100% improvement in mileage.
