Does anyone know why the computer calculates higher mileage than hand calculated? I asked the local Honda service manager. His answer implied that he had no idea!

The Scan Gauge II is incredibly accurate and will help you keep track of all types of information. Got mine from Ebay for $160, free shipping. Best automobile investment I've ever made. It generally agrees by 1/10 to 2 1/0, gallons used, and the same for hand calculated mileage. Keeps track of the tank, current trip, real world mpg, previous days mpg. Fuel used for them, remaining fuel, gas and miles used from the tank and remaining in tank, cost for all the above, and stuff I don't even use. It also tracks function, such as water temp, maximum and average speed and rpm, and so forth. It plugs in to the diagnostic port under the dash. Nothing else to do other than follow the directions and do a set up for your car. Such as fuel type (gas or diesel), tank size, and size of engine. Then reset your "trip" odometer to "0" and fill up with gas. Press fill up on the SC. Drive out the better part of that tank. Fill up at the pump you used in the previous fill up. Then adjust the SC to agree with the actual amount of gas you pumped. Also adjust the SC to reflect the actual miles driven on that tank to agree with your odometer. Although the SC may have been slightly more accurate, as it measures mpg even while backing up. But if they agree, it will make you feel better about the hand calculations. Then you are good to go. If you fill up at a different pump later, and there is a disagreement, you can bet it had something to do with pump metering, the angle the car was at, or how you operated the nozzle. The in dash trip computer is optimistic by all accounts that have reported on these forums. It is that way and will continue to be that way, Period! It is useful to let you know that it records better or worse mileage for certain driving situation, but is not "spot on" accurate, and never will be. Kip |

| I just drove from Ohio to South Carolina on my '07 Fit Sport Auto with 2 adults, 2 kids and a lot of stuff (enough that I had to use the mirrors to see behind me). I kept the speed at about 60mph in the 55 & 60 MPH zones and 65mph in the 70mph speed limit areas. I used the Sport mode and left the gear in 5 and downshifted on steep hills. I used cruise control all the time, even in the Appalachian Mtns (more downshifting to 4th gear, but not as much as you'd think). My MPG on the 4 tanks (2 going and 2 coming) were 43, 39, 36 and 42mpg (the 36mpg included driving around on local roads during the vacation in SC). I didn't do any hypermiling, and the tires were at 35psi. The key is to use cruise all the time and keep it in 5th gear manually using the sport mode and only downshift to 4th if the speed starts dropping. Newton's law about the small amount of energy required to keep a moving object in motion can really be seen when using cruise control. It saves so much more gas. Driving at night with no traffic helped too! | |
My '07 Fit Sport manual now has 65,000 miles and my average fuel economy is 36 mpg. I bought the KIWI MPG device to see if I could do better ('07 and '08 do not have on board mpg meter). What I discovered is that my car is just inherently efficient. By "eggshelling" the accelerator, coasting stops, lower speed, easy acceleration, and playing the KIWI MPG games I could only get 2 or 4 mpg extra. What a bore. That strategy is for big, heavy, overpowered dinosours where 2 - 4 mpg improvement in the 12 - 15 mpg range really mean something. At the 36 mpg level, 2 - 4 mpg is not much and I much prefer to drive the car like I want - the accelerator is an on and off switch (except 1st gear). Acceleration is controlled by RPM required. Opening the throttle to accelerate lowers pumping losses and gets the car up to speed quicker where it can generate the best numbers. The Fit mpg does deteriorate above 70 mph (my self-restricted top speed) though, probably due to the gearing. My commute is 38 miles each way, 75% highway. 25% city.
