Mileage on my new 2009 Ridgeline has been getting better with time. I have found a new trick for increasing mileage and that is to use the cruise control as much as possible, even in the city where there is ample road to do so. Just don’t do jackrabbit starts.

This will kill your mileage. You’ve got to remember your driving a truck with big tires which increase rolling resistance.

I have found that by setting the cruise control slightly higher than my desired speed and then, using the decelerate control bring the speed down to the desired speed. By doing this, you will see the mpg stay higher than if you just set the control at the speed you want and don’t go over theat speed first.

I have been getting 18.5 to 19.8 in the city using this technique. My highway mileage has shown 22.7 to 23.8 consistenly at 68mph on reasonably level interstates. Keeping the vehicle at 70mpg is max for me. I notice that speeds above 70 mpg start to take a toll on mileage because of wind resistance.

There is a big trade off speed vs wind impact. Another thing to remember is not to use the cruise control when the road takes a steeper climb. This causes the tranny to downshift and the engine runs faster increasing fuel consumption.

With about 8K on the clock the mpg is getting better. Local commuting is more in the 18+/- arena. When new, it was in the 15-16 mpg range.

Recently my wife and I took a 1 day road trip from south of Atlanta to Cherokee N. Carolina. Typical N. Georgia rolling hills most of the way with mountains the last 30 miles or so. One area was steep enough that the tranny dropped to 3rd gear.

About half the trip was X-Way, 1/4 four lane roads with traffic lights, and 1/4 two lane roads with some small towns. Total trip was about 385 miles. Travel speed was posted speed limits and very little speeds over 65.

Stopped to eat twice and once for a Pit Stop. Spent about 2 hours at the destination.

Gauge in the car said we got 24.8 mpg. Gas pump and calculator showed 25.1 mpg. Filled up at the same pump before and after the trip.

Let the nozzle run on the slowest setting and removed it on the first click both times. This is the first time the gauge has shown less than the calculated mileage. Might have something to do with the constant running vs my usual traffic type driving.

A week or so later I (alone) took a trip of about 175 total miles to north Georgia and back, but not into the mountains. There were constant rolling hills, for the entire trip. Ran the posted speed limits but not over 65 much at all. Measured the mileage going with a top speed of 62. Trip home had a top speed of 65.

RL gauge showed 27.8 one way and 27.7 the other. Did not calculate at a fuel pump. Even if the gauge is optimistic by .5-.8 mpg, which is usually the case, that is still good mileage for a brick.

Conditions were a pleasant day and AC was not required. Cruise was used when ever possible. FWIW I firmly believe that most RL will achieve this kind of mileage under similar conditions.

In my heart of hearts I believe that if I had driven 70 mph the economy would have dropped 5-7 mpg. But I would have gotten there a few minutes quicker.

Problem with most drivers is a desire to buy cheap gas and run as fast or faster than everyone else. I buy Chevron or Shell 87 octane which have proven over and over to get better mileage than the economy fuels for us.
