Fuel consumption.

I recently bought a 03 toyota corolla 2.0 D4D, I must admit I expected the
fuel consumption to be a lot better , I think 47mpg is what toyota website
says is the expected performance, at present I'm only getting about 34mpg
any ideas why the consumption is so high? (I drive average speed)

Thanks Guys.

47mpg sounds like Imperial gallons. But anyway, a variety of factors affect
gas mileage.

Is this city, highway, or mixed driving?

Are you experiencing winter-like weather in your area?

How are the tire pressures? Are they the correct size?

I think EPA's highway rating for this version of Corolla is 39 miles per
U.S. gallon on the highway; my folks have managed to get 40mpg on a few
occasions with their '04.

Hey High Tech,

Yes I was talking about Imperial gallons, so it works out about
27.5mpg(us), thats pretty poor. Its usually mixed driving, combination of
traffic and straight road. The weather is wet but not exceptionally cold
(10degrees). Perhaps I need to change some filters. Thanks for your reply.

I think the OP's car is a diesel, not currently sold in the U.S.

There must be something wrong. My Panda diesel never does less than 60mpg
and I would expect your D4D to fairly consistently hit and possibly better
50mpgUK as do most similar cars.

Driving style, whether the vehicle is gas, diesel, hybrid, or whatever, has
the greatest effect on fuel economy. Wide open throttle acceleration has a
pretty big negative effect, as does speeding up and slowing down. Many
short trips will result in poorer economy than long trips at steady
throttle.

Next comes road and traffic conditions, powertrain condition, and then tire
inflation.

Not disagreeing with you on any point but his car is a modern direct
injection common-rail diesel which should easily achieve over 50mpg on an
average out-of-town run. Now he might just drive in a gridlocked town
environment for all I know and the normal average speed could be 10mph or
less with frequent stops, in which case he gets about the expected mileage.

I confess that I am not very familiar with modern direct injection diesels,
other than what I've read. Unfortunately, they are not common in the U.S.,
probably because the U.S. consumer still pictures cars belching black smoke.

I guess the bottom line for the OP is to bring the car back to a qualified
service facility to be checked out.
