First let's go over the maintenance checklist:
  • oil level 3/4 full mark?
  • tire pressure 42/40 or max sidewall?
  • recording mileage in database?
  • warm-up segment 1-2 miles of 25 mph or less?
  • cool-off segment 1-2 miles of 30 mph or less?
  • max speed 65 mph or less?
  • Staying out of the 39-44 mph range?
Realize the MPG is a function of speed:


See if there is an industrial park or large shopping center where you can set your cruise control for 24 mph. Ideally, it should be fairly flat, somewhat wind protected (aka., trees), and have no stops. For good measure, warm-up the engine and systems by traveling at ~55-65 mph for 10-15 minutes before entering your 'test track.'

Once you reach the test area, set the speed for 24 mph and reset your MFD. Drive for 30 minutes and report the MFD mileage. The cruise control can hold 23 mph but if there is any small rise, it can 'kick out' when the speed drops below 22 mph. I find 24 mph is a better target speed but experiment.

Now if you want to do better, manually control your speed to hold 18 mph with a range from 16-21 mph. But try to keep it at 18 mph. You should easily achieve 99.9 MPG. If you have a wind, keep on the 16-18 mph range into the wind but you can go 18-21 mph with a tail wind.
