Honda Civic, Fuel Efficiency (MPG)
#2067 of 2125 Interesting historic MPG compro
Feb 26, 2010 (9:41 pm)
Interesting wind up article in latest Car & Driver after 39,700 on their Jetta TDI. They stated that it was the 3rd most fuel efficient car they had ever had for a long term test. As you read this remember that these guys probably drive with a heavier foot than many of us. They got 38 mpg overall on TDI which they said were only bettered by 2 long termers: 2000 Insight (48 mpg over 40K miles) and 1992 Honda Civic VX (41 mpg over 35K miles).
That VX was an quite a car - 1 car magazine (Motor Trend?) got 56 mpg with the VXon freeway test. I average about 45 with mine in mixed drivng. Cost new was about $3,200. Of course it was stick, only had 1 air bag, wind up windows & no power steering Amazing how things change.

Didn't the Civic VX have a smallish displacement engine? Something like a 1.3 liter maybe. And a carburetor?
I had a Civic Wagon in the early 80s with 3 speed auto and 1.5 liter carbureted engine. It got 32 mpg day in and day out. I was an outside service tech for IBM and the car was full of parts and put through just about everything that would contribute to poor mileage. Heavy traffic in downtown Atlanta, cold starts several times a day, etc.. Expect that as a normal family car, it would have gotten much better mileage.
It is one of the cars I look back fondly on. Should have kept it.

I am also from New England. I have been tracking my Civic's mileage on Ecomodder.com since I owned the vehicle (spring 2008). The effect of the seasons is blatant; the graph shows cycles. My commutes haven't changed much in the two years. Click here for the graph and raw data. Interesting.
I suspect part of the cycle is the gas formulation, and part of it is near freezing and below temps (plus other weather conditions like wind). I am noticing now that the ScanGauge shows better trip mileage when the outside air temp warms just a little bit, maybe to around 35-40F, which we are starting to see around here. Some of my trip mileage is now at or exceeding 40mpg again.

I bought a NEW 92' Civic VX w/dealer installed a/c for $11K. I have the original window sticker and base price was $10,350.00. It was EPA rated at 48 city & 55 hwy. I owned the car for 12 years, it was the best little car I ever owned. I averaged between 40-43 mpg. I did manage to get 50 mpg on a trip one time. It had a tall gear and would coast forever, but was a dog off the line. It had a 1.5L VTEC-E sohc engine.
I still have that Motor Trend magazine that they tested it up the California coast and back to L.A. They wanted to see how far they could get on a tank of gas. Honda needs to bring this car and the CRX back. The hell with these hybrids.

I've got about 165K on my Civic now, which has the 5 speed manual transmission. I drive 60% highway / 40% back roads, with little stop and go. Winter MPG is 38, other times of the year it's never below 40mpg. If I baby it, I can hit 45mpg.
This car is the best I've ever owned. Even at this mileage, it still drives like new.

Yes, I'm starting to see my mileage trend up as well since it has warmed up.
I've got it all on a spreadsheet, and last year I saw a significant jump (low to mid 30's up to upper 30's) at the very end of April. I'd suspect that the formulation changes somewhere in that time frame. We'll see if the same holds true for this year.

I think the "summer formulation" came in 2-3 weeks ago. But that's a guess, since it also got a little warmer at the same time.
I took a 52 mile drive from Greenfield, New Hampshire to my home in the Boston area on Saturday (temps in the 65-70 degree range) and scored 50.1 mpg on the ScanGauge for the trip (!!). The tank MPG so far is 44+, per the ScanGauge. We'll see what happens when I fill it up later this week (it usually goes back to its 40-42 or so, still not too bad).
#2075 of 2125 Last two fill-ups exceeded 45mpg

2008 Civic EX, manual transmission.
My last two fill-ups each exceeded 45mpg. Although that's atypical (most fill ups are in the lower 40s or so), I'm impressed. My best ever was 46.45mpg, and my recent 45.95mpg came darn close. If it wasn't raining on the last day on the tank, I may have given 46.45mpg a run for its money.
Just basic hypermiling, that's all (pretty much easing up on the gas). Plus the car seems to do better in the warm but not hot weather we've been having as of late.

I have an '06 Civic LX, automatic with 59,000 miles on it. I average 42-43 mpg on the highway out in New Mexico and Arizona at 75-77 mph. I work in those two states and am on the Colorado Plateau at an average of 7,000' in elevation. Was wondering if the elevation would hurt or help with the mpg. I bought the car in Mississippi and never had it adjusted for elevation.
