# 1985 Honda Civic Wagovan

SPECIAL NOTE: In a crazed moment we decided that our family of four,
including two teenagers, no longer "fits" into a two-door car (the 2001
Civic Coupe -- see below). We bought a new Honda Fit. Stay tuned for
more information.

Here are some figures showing the fuel efficiency of a 1985 Honda Civic
Wagovan. This car was principally driven in the city but about once per
year it was taken (heavily loaded) on a long road trip.

We sold the Wagovan in September 2002 and replaced it with a 2001 Honda Civic
DX.

Go here for a summary of the 2001 Civic's performance.

The following values were obtained using the total distance travelled and
other total amounts. The amount of CO_{2} produced was estimated using
the ratio of 2.4 kg of CO_{2} per litre of gasoline. The efficiency
estimate is too low because some fill ups were not recorded (though the
distance driven still accumulated on the odometer).

Total fuel consumed = 3318 litres
Total cost of fuel = 2218 dollars
Total distance travelled = 46336.0 kilometres
Total CO2 produced = 7964 kg
CO2 per km travelled = 0.17 kg/km
Mean fuel cost per km = 4.8 cents/km
Mean efficiency = 7.2 l/100km

The next set of values were obtained by taking pairs of odometer
readings and using the amount put in the tank as the fuel consumed for
the measured distance. Obvious outlyers (such as efficiency values
obtained when a trip to the gas station wasn't recorded) were thrown
away first.

Fuel efficiency in litres per 100 km
Minimum Mean Maximum
4.6 7.9 +/- 1.8 12

### Emissions Testing

This car recently (2000) had an emissions test.
It scored as follows.

Hydrocarbons (HC): 48 ppm maximum allowed for this model: 350 ppm
for model year >1996: 90 ppm
Carbon (CO): 0.146 % maximum allowed for this model: 4.0 %
Monoxide for model year >1996: 0.6 %

# Figures

### Distance Travelled

### Fuel Efficiency (l/100km)

(Lower is better)

For the metrically challenged I offer the following:
### Mileage (miles/gallon)

(Higher is better)

### Gasoline Price

### Fill Up Locations

### Efficiency as a function of date

### Cumulative fuel consumption

### Fuel consumption vs. Distance driven

The little notches (where the slope approaches zero) correspond to times
when we forgot to record a fuel purchase or entered the data incorrectly.
