    > But I do remember initially being disappointed with the MPG when I bought the car new.

    The graph I have on ecomodder.com is interesting over the years. Time between fill-ups has increased (I don't drive as much, especially during the winter), but other than that it's the same car and same driver only armed with a ScanGauge. Note the change in the graph as the car "breaks in" (or maybe *I* break in :-) )--the humps are a bit higher each year (at least by eye).

    My car is CuteNiceButNotTheSame in the ecomodder.com garage if you're curious (I can't post links/images here for some reason).

    Went to Yosemite in early June, from Seattle area. Down I-5, back home through Reno, Klamath Falls, Bend, over to I-5 at Salem, OR, then home. 1,919 miles. I averaged 43 mpg. I did do a bit of hyper-miling, by going 66 - 68 mph instead of 75-78. The ride back was mostly 2-lane, and lots of high elevation up and down. The fantastic mileage has continued. 2008 LX Auto. Will hit 60,000 miles in the next few days. Runs better now than when new. Will probably come crashing down to reality next Winter, but this is the best Summer mpg, and this is Summer # 3.

    >"-- How is the data reported? Unless someone is showing you a tally of the regular fill-ups over months, the data is suspect. They could be reporting the mpg from the trip computer, doing some favorable reporting (cherry picking the data), or simply measuring incorrectly."

    You and I are definitely on the same page! I've been driving for 52 years. So I've seen and experienced the good, the bad, and the ugly. Learned a long time ago how to ring every mile out of a gallon of gas. Took samples every once and a while just to mainly satisfy curiosity.

    That 03 Pilot was our first car that got every drop of gas recorded, for nearly 7 years. The last couple of years, I was able to squeeze out1-2 extra MPG with the help of a Scan Gauge II. But mostly the "SG" verified what I had already figured out.

    Here are some interesting points.

    -On a flat road and a calm day 65 mph is about 2 mpg less efficient than 60 mph.

    -Using the "GPH" scale, going down a long hill at most any speed over say 45 mph the "Gallons Per Hour" would drop to "0". This indicated to me that the fuel had been shut off. If I shifted to neutral the gage would go to something like .24. Which was about the same as when sitting still and idling. The Ridgeline doesn't do that. It drops to around .24 GPH whether in gear or in neutral.

    - On a given stretch of road, there may be 1-2 mpg difference depending on the wind direction which verifies that wind resistance plays a role in economy.

    I agree that a Scan Gauge is a useful tool.

    Here are some observations from years of driving experience.

    -Hilly roads do not get as good mpg as flat roads. Going down hill does not make up for the extra fuel it took to get up the last one.

    -Speed makes a big difference in mileage. At higher speeds there is more wind resistance, more tire resistance and likely some other things. Example: On a trip to Myrtle Beach from Atlanta, In semi rainy conditions, with 4 people and luggage on board the Pilot got 18 mpg. Most of the time the cruise was set on 80 mph. On the return trip the next day, with the weather pretty much the same and the same load, the economy was right at 27 mpg. at 60 mph. This was not really a fluke as this type thing showed up time and time again.

    In a nutshell, I have trouble understanding how some folks can get high mpg traveling at high speeds, unless they are driving a transformer that becomes an arrow as speeds increase. :confuse:

    - On a 42 mile trip, that I make fairly regularly there are basically 2 ways to go. One involves about 30 miles of X-Way with gently rolling hills. With the cruise sat at 60 mph the trip mileage would be in the neighborhood of 26-27 mpg. The other way involves a lot of back roads and a 55 mph speed limit. The hills are more frequent and steeper. Even at the slower speeds the mileage would drop back to 23 mpg or so. Difference being the steeper hills caused the tranny to down shift more often.

    Some folks believe that if they get say 20 mpg going up hill and 40 mpg doing down for the equal distance that the average is 30 mpg. Not true!

    In summary it depends on how mileage is figured, if it is figured at all, and whether or not they are "Cherry Picking". ;)

    FWIW the Ridgeline gets about the same mileage as the Pilot in local driving, but 3-4 mpg lower on the road. :sick:

    Wow... great mileage on a gas vehicle. I thought I was doing pretty good until I saw your numbers.

    I can only even sniff 40MPG if it's almost all highway driving with little or no traffic.

    Yes, your trend is similar to my experience.
  • My 2006 Honda Civic EX Coupe with Auto transmission really depends on the weather. During the winter I get about 28 around town and 34 on the highway. In the summer I average 33 around town and with the AC blasting (gets over 100 here sometimes) I average 38 on the highway. Not a bad mix of numbers, I think!

    I drove a 2006 EX with auto for 3 years - averaged 33 mpg in mixed driving.
    My 2009 hybrid averaged 47 mpg over the past year on the same drive.

    I never got those numbers either. I had a honda civic 2006 ex 4dr sedan. Mix of city/hwy driving but never saw better than 24 mpg (except on a road trip and it went up to 28). I was disappointed since that is about what I got with my 2001 Toyota Rav. I now have a 2010 Toyota Yaris and I am averaging 32 mpg. My driving style is the same on all vehicles and my daily routine is the same. Honda was a nightmare with repairs and handling in wet weather. I am so glad to be back in a toyota.

    Have gotten this mileage consistently on my '06 LX & am very pleased. With 30k, it's still tight as a drum without rattles or squeaks...love it! The Fusion HR tires are a bit on the noisy side which will be addressed eventually. Can bet that the 2012 model will have 40 highway to match the other manufacturers. Spoke with the wife about her getting a 2012 today, as we had an error code on her Mazda3s dealing with the thermostat & such which will cost about $400.00 if the light comes on again. She's leaning towards the Hyundai twins or the Cruze at this point.

    Kipk, I've never heard of any current generation Civic having that dismal mileage in heretical, so am a bit skeptical to say the least. But since it's gone, it's a moot point!

    The good news is my daily work commute has been cut from 36 miles each way (80% highway) to less than 4 (all back roads). Yow--not used to that!

    The bad news is between the short commute and the cooler weather (it has been below normal here in the northeastern US), my '08 Civic manual has dropped from about 43mpg to 36mpg. Still quite good, considering.

    Hey, I'll take the drop in mpg for a daily round trip of less than 8 miles vs. over 70 miles before. :-)

  • I've got a 2005 Civic HX, manual transmission, with 310,000 miles (no kidding). Over the years I've gotten 47 MPG highway, although I'm now seeing closer to 45 mpg. I've used synthetic oil the entire time, and I replaced my timing belt once and head gasket once.

    400,000 here I come!

    At what mileage did you have the head gasket job done? Sans the (potential) head gasket job, I look forward to 4 TB/WP changes or 440,000 miles on an 04 Civic A/T.

    I just had the 110,000 interval TB/WP changed @ app 118,000 miles (a modest 8,000 miles over due) From what I can swag, the belts could have easily lasted to 150,000 miles.

    110,000 to 120,000 miles are really the mileage the "major" tunes are due. With an eye to multiple cycles, I had the valves checked and adjusted, spark plugs changed and retimed, A/T and coolant changed. The thing that triggered the whole thing was the front brakes needed changing.

    The fuel mileage started off in a range of 38-42 mpg (daily commute 54 miles R/T- for which the majority are done 83%), where it remains (second TB/WP change) and at app 121,000 miles.
  • I replaced it at around 250,000. Did it myself for a cost of less than $150.

    The car will hit 350,000 next week, and still no problems.
  • RE: lower mpg with higher speed...my 1995 Toyota Avalon XLS will get 28mpg highway 70mph or 80mph on long trips. I measured this on a recent 700 mile round trip. Years ago, the car got 29.5mpg highway 70mph or 80mph. The V6 seems to not care whether it's 2500rpm or 2900rpm. Faster does burn more gas per hour, but you're taking less time to get there. Aerodynamic drag and tire rolling resistance, etc go up at 80mph but my Avalon does get the same mileage either way. I am meticulous in my calculations. (Next car will be either 2010 Honda Civic EX or 2012 Hyundai Accent SE.)
  • I am driving a 2012 Civic Coupe LX and have been OCD about tracking my MPG because that was my sole reason for getting a new car. Granted I could have bought a car that gets higher MPG (Toyota Prius), but I am a Honda fan and like the looks of the Civic Coupe much better than the Prius - plus the Prius cost more.

    Anyway, my driving consists of 60 miles of all highway driving each day with about four slow down/acceleration points. I set the cruise control on 60 mph and am in the ECON mode almost all the time. At nearly 3,000 miles I have filled up 7 times. My average is 43.2 mpg with my best at 44.1 mpg. I have higher octane gas in right now and am interested to see what happens.

    I bought my 2012 Honda Civic LX lease in late Novemeber 2012. Cold weather seems to affect mpg quite a bit. In the warmer weather of November I was getting in mid 40's combined, close to 50mpg on highway. Has dropped about 7 mpg in cold to really cold weather. Overall, much better mpg than I expected, so reallly pleased as engine is still breaking in at only 2,000 miles.
  • Where are the 2013 owners? What MPG are you getting on your Civics?

    I am still on my 1st tank of gas so don't know the MPG yet. The digital MPG is all over the place so not reliable until I can do it manually at my next fill up.

    Don't get too excited either way concerning mileage until you actually do the calculations at the pump. At that time you will likely find that the digital gauge is pretty close. Maybe .5 mpg to 1.5 mpg optimistic.

    I went to purchase a Civic, but ended up with a Fit due to it's cargo space.
    The Civic is EPA rated slightly higher than the Fit, but this post should still prove to be accurate enough for purpose.

    My 14+ drive home from the dealership on back roads, with a few traffic signs and lights yielded 41+ mpg. WOW "I'll take that"!

    Stayed at the house a short while and ran some local errands. 2-3 miles at a time for maybe 15 miles or so. Getting out and shopping quickly 4-5 times.
    The avg MPG dropped to 33 mpg. So effectively we were likely getting http://www.toptiergas.com/

    Got 53'mpg during a 15 mile trip to work. MPG in Civic seems to suffer a bit in cold weather. With temps in mid 70's it really kicked buttock. Can't wait for temps in 80's and 90's. LOOKING TO GET 60 mpg. :surprise:

    Let us know what you're getting in overall fill-up averages. Those are a better tell than 10-20 mile snippets that leave greater room for error. That's great to hear though!
  • jipsterjipster Posts: 5,345
    I would say overall average (80'% hwy 18% city and 2% other) has been around 39mpg. That's been winter driving.
