#86 of 95 Re: Ridgeline Mileage Testing. [eddiem]

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 the\at 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.

#88 of 95 MPG sucks on 2008 Ridgeline
Feb 10, 2011 (11:10 am)
I bought my 2008 Ridgeline used 4 months ago with 25K miles. I now have 32K and have been getting 15.5, 12.5, 13.5, and twice I got 16.5 mpg. I drive 50% highway & 50% city/suburban. I live in Houston, Texas. I don't haul anything. I'm fairly easy on the pedal and I don't see how fast I can get to the next light. The dealer said I'm getting normal mpg. Can any body tell me if this is true?

To scottmpg, I had my 2006 Ridgeline for 6 months and put 10,000 miles on it. I didn't take any long trips but did a lot of short trip driving and I always stayed at 18 mpg or better. I drove it as you say you're driving. I read on one post that if we have a truck we're just pushing a brick down the road and shouldn't expect good MPG. I have had a 2005 Tundra 2wd double cab for 2 months and am bouncing between 17-18 mpg....just added a Extang bed cover and hope to see 1/2 of the 10% MPG improvement they advertised...but I'm not holding my breath. I will add new spark plugs (probably the NGK fine wire Iridium IX) next...oh and I still have to change from crude oil to my Amsoil 0w30. Maybe I will get another 1-2 mpg from these latest tweaks. Just this morning a buddy sent me this: "A good hot FORD plug is the best you can do on ANY internal combustion engine running 87 to 104 octane. All you do with a plug will be robbed by ONE under inflated tire.....im serious!!! Keep the air flowing into the engine.....run a good plug...keep the tires up....keep GOOD gas in it and its about all you can do. Slow starts and not going over 50 make an INCREDIBLE diff as well as high octane gas."
Sounds like your Ridgeline may need some tweaking also....maybe at the dealership after you do all you can do? Good luck!

You are getting about what I get.
I think I just filled up and it was 17, with a highway trip on that.
I feel all my vehicles lost around 2mpg where 10% ethenol was required. I've seen 21mpg on one highway trip in my 2006 Ridgeline, and this was on gas without ethenol. I doubt I will ever see this milage again.
I do drive fast, 70 or 75 depending on posted speed limit. I do try to keep air at 32pounds or more, but this truck does seem to leak or drop a lot of presssure in cold weather. I've had the low pressure warning come on twice since owning it. It comes on at 26#.

Your mileage seems low to me, but what do I know?
We had an '08 RTS that got about 16-17 in town and 19-21 on long freeway trips at 75-80 mph.
We traded our '08 for a new (leftover) 2010 RTL in December. It's not broken-in yet, but current mileage is 15-16 in town and 18-20 on the highway. I'm hoping it will improve after it gets a few thousand miles on it.
I agree that ethanol added to gas kills your mileage numbers. In my experience, 10% ethanol = 10% worse mileage. Almost like paying for something that doesn't even combust in the engine--weird. We are forced to buy gas with ethanol in the winter, but can get REAL gas in the summer here in Colorado, and the mileage numbers go up when the ethanol goes away.
On other Ridgeline forums, some owners claim to run 34-35 lbs. of air pressure in their tires to improve the mileage and it seems to work if they do lots of highway driving.

Actually, 34-35 lbs is only a couple above what Honda recommends. It should not be an issue at all. Mfrs have to compromise between mpg, tire life, and ride comfort.
I've noticed the slightest increase in ride firmness, about the only penalty driving a couple of psi over. Need more time to evaluate mileage.
With Ford's new ecoboost engine, and the mileage/hp ratings of some others, I have to wonder the direction Honda is going. Makes me think maybe another year for the RL and then no more.
I think there has been a slip in quality too, although over the long haul I think a Honda will always persevere. But I am concerned they are not as innovative anymore. It's great having tried and true models like Accords and Civics, but things have become pretty stale in light of the competition, including other imports. Oh well, just my rant!
Back to the mileage, on longer trips I try to hold to 65mph even in a 70 zone. It seems as soon as the tach starts to rise the slightest bit above 2K, mpg starts heading for the toilet. Don't get me wrong, overall still love the truck.
#94 of 95 Speed kills mileage
Jun 25, 2011 (4:27 am)
Our 09 Ridgeline consistantly returns 25-27 mpg on the road at 60 mph. Depending on terrain and load. At 70 mph the mileage drops to 20 +/- mpg. Running the AC lowers those numbers by about 1 mpg.
I agree with dboe. When the tach hits 2000 the milesge drops fast.
