There just "Seems" to be something wrong with this picture. Can't imagine how the mileage could be so bad and not be getting error codes. First thing I would do is the Idle learn procedure (ILP). You can find that on page 11 of the Pilot "Real World Mpg" forum. Do it EXACTLY as it is written. No short cuts. If that doesn't help, you need to become a Fixture at your dealer. Top off the tank and have a technician drive the car for a hundred miles or so and check the mileage, with you in the car. Another thing, would be to drive one of their demo Fits for a hundred miles and see what kind of mileage you get. With legitimate mileage that bad, possibly the states "Lemon Law" would help. The car is not as "Green" as it is supposed to be, therefore not meeting EPA standards. Kip |

Top off the tank at a gas station that is as close as possible to an entrance to the highway. Fill the tank until the pump shuts off, and STOP. Clear out the trip odometer. Then drive as far as you can in one direction on this level highway, with the cruise set at a moderate speed--either around 55-60 mph or whatever the speed limit of the highway is (if no cruise, try to maintain a set speed with light pressure on the pedal). (As was mentioned, be sure the transmission is in the highest gear.) Then turn around and do the same thing in the opposite direction until you return to the same gas station you used before. Fill the tank at the same gas pump you used the first time, until the pump shuts off. And calculate your fuel economy for the trip (the longer the trip, the better). The mpg should be close to the EPA highway estimate for the car, at least. If the speed was around 55-60, I'd say the mpg should exceed the EPA number. If not, if instead it's closer to 18 mpg, then I'd say the car really does have some kind of problem. |

Replying to: bilbofett (Jul 10, 2009 7:09 pm) Only thing I can offer is try the ILT mentioned in other posts. The thing that really puzzles me about all the FITs is the wide range of MPG reported, from 15 to 44. That just doesn't make sense to me even with all the different factors that play into MPG.

48.4 mpg for my first tank of gas using on board gauge Wow or what gives? Actual from mileage to gallons used was 37.5 mpg which is still a WOW. Base model five speed manual 80/20 highway/city. love my new fit. JAREW

Replying to: jarew (Jul 22, 2009 8:47 am) I got an indicated 42.4 during a rather "aggressive" test drive session a couple of weeks ago. Even if that translates only to a real-world 34 mpg, it's still better than my Civic gets when driven comparably.

Replying to: stephen987 (Jul 22, 2009 11:11 am) i have to think honda could remedy this, but too many drivers not in the know would have to face the reality that the mileage of the fit isnt as rosy as they think. |

Replying to: stephen987 (Jul 22, 2009 11:11 am) Some of the disparity across reporters may be CPU versus real mileage--although I also noted before that I actually got 47.5 mpg over 280 miles on an interstate tank that involved a lot of drafting behind 18-wheelers doing 65 mile per hour. |

A "Scan Gauge"can be corrected for errors. It takes a couple of tanks to get it "Tuned" to the car. When doing a fillup it will say how many gallons it thinks were used. The driver can input the correct amount according to the gas pump. It will also say how many miles were driven. The driver can can calibrate the Scan Gauge to the car's odometer by adjusting the indicated speed. For example the car is driven 100 miles according to the odometer. But the scan gauge says the car traveled 98 miles. That is a 2% difference and the gauge can be adjusted to reflect "+2" . Then the next time the car is driven a given distance, the gauge will agree with the odometer. Or pretty close as it also measures the fuel used when in reverse. Problem is, that odometers are not the most accurate of devices. So we really don't know if the odometer is more accurate, or the gauge. If we don't believe that, Next time on an X-way, reset the tripometer at a given mile marker. Drive a hundred miles and see how far off the odometer really is. Another, and even more accurate way, is to set a GPS for trip. It will tell us how far we have traveled as well as how fast we are going. That can be compared to the odometer and other devices. The differences folks are seeing may actually be the cars odometer, the cars trip computer or a combination of the two. The key for super accurate results, the fill ups must be done exactly the same way every time. Same nozzle setting, same pump, same car position, etc..And know how accurate the measuring devices actually are.  Kip
