#1024 of 2125 Real World Mileage - FANTASTIC!
Jul 28, 2007 (7:23 am)
I bought a 1994 Honda Civic Sedan EX because my round trip commute to work is 110 miles and my Dodge Durango was costing me a small fortune in fuel each month.
I put the cruise control on about 62, and then drive straight to work on a major interstate with no lights. For my first 3 tanks, my mileage has been:
I fill the tank until the gas dispenser stops, and then reset the odomenter, and then calculate the mileage at the next fill up. Funny thing though, I thought the tank on this model was 11.9, but when the needle is in the red zone of E, I fill up and only ever get 8.5 gallons into the tank.
Very happy with new used Civic, and the great gas mileage.

Just took a trip from Lincoln, NE to Florence, CO. Mostly level driving for about 350 miles, about a 15 mph headwind most of the way.
From Lincoln, NE to North Platte, NE, it was 225.6 miles. I filled up again in North Platte, where I put in 6.554 gallons of Premium (91) at $3.34 / gallon. That's 34.42 mpg.
I then filled up again a little south of Denver, CO...between Denver and Castle Rock. From North Platte to that gas station was 260.8 miles. I put 7.887 gallons. That's 33.06 mpg.
Speed limit was 75 mph. I had the cruise set at 79 mph. RPMs were right at 3.4k at that speed. I'm sure if I backed down to 71 or so, I could add another mpg or so. But, I think that's pretty good in that car.
Once I got past Denver/Colorado Springs and got into the mountains, I stopped keeping track.
Mileage on the car when I left Lincoln was about 2300. Still on my 2nd oil change. Going to change it when I reach 3750 and switch to Mobil 1 synthetic.

With mostly highway driving between 50 to 62 mph, I consistently get between 38 to 41 mpg. Usually 38 to 39 though. I did however just spend a little over $1,000 on suspension repairs (struts, engine mounts, etc.). That was a major "ouchie!"

Filled up tank to neck of filler tube before trip, so its an exact fuel HWY consumption
I used up 13.615 liters for 204.1 kilometer = 126.821 mile The fuel consumption works out to
6.67 liters/100 km = 42.350965 miles/gallon(UK)
6.67 liters/100 km = 35.2645552 miles/gallon(US)
What is everyone else getting?

Be advised, filling your tank up to the filler neck is a very fast way of destroying some of the emissions equipment on your car, especially the evap cannister. A far safer way of figuring our your mileage is to buy a ScanGauge and mount it in your center stack.

I am interested in the ScanGauge because of all the info it offers. Thanks for the link.
Does it calculate real time mileage somehow or is there a gas flow sensor reading in the OBD II system? I haven't been able to tell from their manual.
My vehicle is a new 07 Civic LX, don't have enough miles on it for a reasonable milage measurement yet, but it does look encouraging at 42 mpg for the second tank full covering 400 miles. 200 hwy and 200 short 10 mi one way trips.

As I understand it, the MPG calculation is interpreted as it is derived from the fuel injection system (i.e. flow rate of the injectors, how often they're opened and for how long, or some such) and not a direct measure of the fuel used. That said, I've now had 5 different cars from three different manufacturers that have used an ODB-II based MPG calculation, and all of them have been within a couple percent of DOBA (ask Marisa Tomei if you don't know what that means).

#1032 of 2125 Amazed by my Civic
Jul 30, 2007 (12:51 pm)
I've posted a few times here and I've heard all kinds of results on the new (06-07) Civics. Over the past week I got to take two trips in my 07 and the results have been quite interesting. On a shorter trip of about 250 miles at moderate speeds (not above 70) and almost all highway, my EX AT cranked out an amazing 48.8 mpg! I almost couldn't believe it myself.
However, on a much longer trip of 657 miles, it showed a much more believable 35.71 mpg. I am still, however, very pleased because on this trip we seldom ran less thn 70 (usually 74-75) on the interstate and we had a little bit of running around in town.
One thing I have wondered about is what kind/Brand of gasoline the rest of you have been running in your Civics. I usually buy Exxon or BP but occsionally will buy another brand if it's cheaper or more convenient. I was running BP when I got the 48.8. I'm just wondering if there could be a difference. My guess is no, but who knows?
I'm going to be taking several more trips over the next couple of months so I'll keep you posted.

When I get "spikes" like that, I usually just average the two together and get the average for those two fills. Since you gave info to extrapolate the gals: the average is 38.58 mpg. Hope you continue to have great fuel mileage.
