    You might not see what your data is really telling you, but your conclusion is almost predictable given the fact you/your driving style/environmental conditions are very very easy on the vehicle. This is reflected in very highly standard deviated fuel mpg. Your oil at the mileage indicated has a LOT of active life left. So in that sense you are walking the walk, but talking like you are not very sure. In addition it is remarkable as you get those figures at altitude!!! Altitude as most folks know saps both power and mpg in a normally aspirated engine like our gasser Civic's.

    ..."I switched to Mobil 1 around 6200 and show 70% oil life left."...

    This is HUGE as the OLM is calibrated for the CONVENTIONAL 5w20 Honda specified oil with a TBN of 7 with no provision for calibration for synthetic oil Mobil One 0w20,5w20) or operatively, a TBN of 12.

    So (given your quote) your consumption rate is 6200/2.1= 2,952 miles per TBN. If you were to keep the oil to ZERO TBN (or some safety factor usually), The lightness on the vehicle indicates a OCI of 20,000 miles!!!!!! This is with, I repeat CONVENTIONAL OIL! So the same math with a 12 TBN comes out to 35,424 miles OCI's!!!!! .These are absolutely awesome numbers!! I would just do a baseline UOA at say 10,000/20,000 miles and going forward do trend UOA's to see if you are on track. So if you just do the 10,000 miles OCI's or the OLM you will almost have as much safety factor left as you had consumed !!

    I reset trip B at the oil change so just checked the thing. Current miles 9131, trip B 2970 miles. However oil life has been reading 70% for some time, should be clicking down soon. Present oil is Mobil 1, 5w 20 as recommended by Honda I think. I did change the filter though, just haven't broken the habit.

    I sort of try to make clear my driving conditions are not typical to most people. Also being a retired old part I am seldom in a big hurry to get anywhere and rarely exceed speed limits. However the payback is beginning this winter, unless the mud is frozen the Civic won't make it to the hwy or back I have use my 4 W drive Dakota.

    I am not sure how comfortable you are with these, but two things:

    1. Change the oil filter at the Honda oem recommended "every other oil change" or in my case 20,000 miles. Indeed if you are so inclined (since you use Mobil One 5w20) change oil AND oil filter at 20,000 miles!!

    2. Switch to 0w20 Mobil One. You MIGHT notice a .5 mile increase. But given what you are getting for mpg, it will probably just shorten the "dry lube" cold weather oil flow. There will be NO sotp feeling.
  • We bought our '07 Civic a couple of months ago primarily for achieving better gas mileage. We almost bought a Prius and now wish we did.

    The car is great except for the consistent mileage of 21-22 mpg. Maybe a bit higher with all freeway but 21-22 mpg for normal metro driving. Revised EPA now show 25 city and 36 hwy.

    This is horrible for a little car. My 6-cylinder Sienna approaches 19 mpg regularly. I could have an SUV and get similar mileage to our Civic.

    I feel ripped off and won't recommend this car based on mileage to anyone.

    Anyone else getting poor gas mileage?

    it sounds like one needs to change driving habits. Accelerate slowly coast as much as you can up to red lights. I think its a matter of the way you drive....i.e. you just stated you can even almost average 19 with your Sienna. To illustrate my point.... on 12-19, just two days ago i borrowed my wifes...yes..you guessed it..SIENNA... used it for a couple of hours. Ran from Orange County to Los Angeles, about 50 miles each way, plus about 10 more straight city. Kept it at 65 mph all the way there..went real easy in city driving.. coasting to lights all i could. Averaged 33.6 mpg. In my civic on a trip like that...driving identically, would have returned me between 41 and 42 mpg, its all about how you drive. Hope this helps

    "Maybe a bit higher with all freeway but 21-22 mpg for normal metro driving. "

    Something bad wrong with that freeway mileage. May need the car checked? Even the metro sounds out of line.

    As somewhat of a comparison, with a 6 cyl 4w jeep cherokee I routinely ran 25 mpg mostly hwy and average a bit over 40 over the same route with the civic.

    Look. You are your driving route! That's it! Many cold start,short trips and anyone is lucky to get 20.
  • ras314ras314 Posts: 43
    Unfortuntaly most of this winter will be short (7mi) trips in the Civic because my driveway needs to be frozen to get the car to the hwy or back. Besides I don't want to be in heavy snow with it. So far it looks like around 30 mpg in cold weather vs maybe 35 in warm weather. Not stop and go but includes some warm up time.

    I think a bit more than 21-22 mpg for freeway driving is unacceptable and may indicate a problem with the car.

    After reading the above, I feel pretty good about my average 28 to 30 MPG. 85% Hiway no stops to and from work. Am still quite disappointed as I was assured that it would average 34 to 35 in everyday driving. Moved to this from an 04 Accord that got me 27 to 28 MPG average on the same route. Downsized for very little impact.
  • I purchased the car for its gas milage as well. 34 - 40 what a pipe dream. I travel 60 highway miles one way in little to know traffic and the best I get is 28 MPG. Have taken back to the dealer twice and the same response. Can't replicate problem and diagnosics check out fine. What a piece of crap. Had three Dodge's with v-6's that got better gas mialge than this. I have been had. Any other stories? Has anyone got the dealer to acknowledge the car is crap.

    If you can, you might want to take the competition like a Toyota Corolla for a spin for a day and do the same. Most dealerships will let you test drive one for a day. (or they do around here anyway)
  • I purchased a 2007 Honda Civic Ex because it's supposed to get good gas mileage. It doesn't. I regret the purchase. It is supposed to get 30 in the city. It barely gets 15mph. The dealership (Capital Honda) tells me that I should expect that. But that is the opposite of what they said prior to my purchasing this car. They won't agree to look at anything to see if there is a problem like a possible partially functioning thermostat. Based on what I am hearing now, the poor gas mileage is a common problem. The dealership, as well as the car company itself, should be ashamed. The old Honda's got great gas mileage. The new ones are horrible. I feel duped and resent it. Don't waste your hard earned money on a Honda.

    "It is supposed to get 30 in the city. It barely gets 15mph."

    That would depend on the type of "city" driving you do.

    What kind of car did the Civic replace? What kind of mileage did it get in same driving conditions?

  • My 08 Civic EX-L is getting about 31-32 consistantly on a 100-mile round trip commute averaging 70-80 mph. Was hoping for a little more, but I am sure if slowed down, I'd do a little better. Otherwise the cars been great. But I would have probably gotten an Accord had I known.

    I have an 08 exl auto and Get no less then 30 mpg usually combined driving 40 percent highway 60 city I get 35 mpg.
  • kipkkipk Posts: 1,576
    kevman3,

    Your mileage would increase a lot at 65-70.

    An Accord (same year model and equipment) will not get the mileage that a Civic does, under identical driving conditions.

    I just came back from a trip up to Canada in my 2007 EX/AT Sedan. The round trip was about 1300 miles (straight shot up I-81 from Virginia to Ontario and back). I averaged a total of 38.5mpg, using cruise control as much as possible and sticking between 65mph and 70mph.

    Even in my normal work week commuting driving - all local urban traffic (nothing over 40mph) and rarely more then 5-8miles per trip I average around 26mpg. I figure that's pretty good, since all the idling in city traffic intersections is bound to make a big hit on mileage. And the car barely gets really warmed up with my short morning commute on these cold mornings.

    For what it's worth, from past experience, my civic's highway mileage plummets as soon as I start cruising above 70mph.

    Getting a consistent 29 mpg's on my 10 mile commute to work...it's just a straight shot up one major road with multiple lights. Can't really complain about that kinda mileage and am still pleased with the car.
    My daughter has her mind set on a Hyundai Elantra but we'll look at all the cars in this segment just to be sure.

    29 mpg's for the freeway? My 04 4runner gets 23mpg's....please tell me that you get more than 29mpg's, I'm considering trading my 4runner in for a civic gas milage purposes.... :confuse:
  • mjstenmjsten Posts: 17
    My average mileage for 3500 miles is 28.3. 80 - 85% of the driving is on hiways at 65 - 70 mph. I would strongly recommend that you ask your dealer to let you test drive for a short period, maybe ovenite, and test the mileage. I have been told that it will get better after some magical "break in" limit is reached, will wait and see, but from the first tank, the mileage has been consistant.27 to 31. As a matter of rafct, today, I filled it up and averaged 27.4 mpg.

    '06 Civic LX.

    27.4 mpg.....maybe I will hang on to my 4runner.....if thats the case.

    My dad drives with a lead foot. According to my Garmin StreetPilot, with an average speed of 79 MPH, a max speed of 91 MPH, and regularly passing with a downshift and zing to 5-6k RPM - he got 32 MPG. Under my mom's driving (she is much more gentle, and always got EPA or better in her Odyssey van as well), she sees around 37 MPG at 75MPH with A/C running.

    2007 Honda Civic EX Automatic, and they already have 30k + miles on it!

    My 08 EX-L gets 31-33, going 70-85. I am sure if I slowed down, I would do better. But the morning commute on the Garden State Parkway and NJ Turnpike will not let you go 65. Everyone is doin 70-90. Gotta keep up. My 01 Maxima used to get 22-24 same commute, and used premium gas. This includes a 15-20 minute average wait at the tunnels too. Love the car. Gas may be $4.00 by this summer....

    During the Christmas and New Year's Holiday Season, we did the "Pizza Dude" delivery drill.

    (short trips, short mileage, short term, lots of start and stops, lots of idling in strip malls, retail malls, club stores, parking lots, super market stores, LOADS of MAX fan heat and A/C use, etc. ) 4 to 6 different drivers, up to 5 folks in the car)

    We filled up and turned in a 34 mpg for a tank full.

    (normal commute 38-42 mpg: for a 10.5% to 19% range of decrease)

    (We have a 20,000 mile oil and oil filter OCI coming up in 3k for a 60,000 miles interval.)

    Wishing all who follow this thread, A Happy, Healthy, Prosperous New Year!

    Probably more on topic, Wishing one and ALL: great fuel mileage with NO break downs!

    Ruking1....is this on a new Civics?

    wooder,

    "29 mpg's for the freeway? My 04 4runner gets 23mpg's....please tell me that you get more than 29mpg's,"...

    Sandman46 said it was 10 miles of a single road with multiple lights.

    We don't know his speed between lights, how many lights there are, or total time for the 10 mile commute. How much starting and stopping, how much idling, etc...

    If you are getting 23 on a 4Runner, You should do very well in a Civic, under similar conditions.

    Ours is a 2006 EX automatic sedan.....in town between 23-25 mpg depending on the season, lower in winter (north east) and middle 30's on highway drives with a high of around 37 mpg driving responsibly. You cannot believe a 4 Runner is as fuel efficient as a Civic!!! Not possible given the physics of the vehicle...weight, gearing, blocky body with poor aerodynamics, 4 wheel drive and all the complexities and parasitic losses involved with it, probably a V-6, nope no way. The current EPA sticker (for 2008) is very much more aligned with what we actually get than the previous "pie in the sky" EPA stickers including the one on the car in 2006 which said 30/40 city/highway.
