1990 accord - winter gas mileage

Hi all,

My 1990 Accord eats up a lot of gas this winter. I've filled up 9 litres
or so for ~65km. It's been cold outside about -10 to -15. I'm not idling
the car, just driving in town.

What should I do to get it to be more efficient. Last oil change was in
December.

thanks in advance,
-Vlad

You used 9 liters in 65 kilometers?? I would look for a leak!!! Or
maybe someone is siphoning from you!

Take seriously the advice on using only OEM for ignition
parts.

I do a lot of intown driving - many rides short distances. In the
summer fuel efficiency is about 11l/100km in town.

That is about 15 mpg. I would suggest that there might be a lot of
error in the refill factor. You need to run it down to the last
quarter of the tank to get the best accuracy.

I am also wondering how many short trips you do. If you are driving
it 5 miles through the city making two or three stops (e.g. shopping)
along the way and then parking it for 10 hours or more then 15 mpg
might be about right at these temperatures.

About 21 mpg. Is the -10 to -15 degrees F or C? If it is F, then you
may be lucky the mileage isn't worse.

Yes, that figure is just over 21mpg for US gallons, which is pretty good
for all-city, short-hop driving.

Since the OP is in Canada, his temperatures are Celsius. -15C is +5F. Many
short trips in those temperatures mean extremely high fuel consumption.

Thank you all,

Yes, all my trips are 1-2 km to the grocery store and back at around -15C
in Canada. I never had these problems a few months ago when it was still
above 0.

Sure..The choke/fast idle/ECU rich mix is going on longer until it
warms up.
Once warm, there shouldn't be a whole lot of difference. But when
cold,
they drink the gas. And if it takes a good while longer to warm up,
just
that much more gas.. If you do many short trips in the cold wx, it's
going
to drink more gas. The car barely gets a chance to fully warm, and
every
time you go again, the car is probably cold again, and has to start
over.

This use is also very hard on the engine. There is going to be a ton
of condensation and unburned gas in the crankcase and exhaust. If you
are using the car this way, you should take it on a 20+ km drive once
a week and change the oil every 3 months.
