Dreadful Fuel Economy!

[Adam786]

I Love my Corolla to bits, I think its the most complete family hatchback out there!

But I am getting really bad fuel economy lately and my car is a 1.4 petrol.

I get a maximum of 350 miles out of a full tank

Thats 3/4 City and 1/4 A road driving! and its like 31 mpg

Anyone else experiencing similar problems??

The "official" average is 42mpg so you are a bit below par

Have you checked your tyre pressures?

When was the last time it was serviced?

How about using a K&N air filter and putting something like Forte fuel system in the tank? Or some BG44? Are you using a full syn engine oil and gearbox oil? When was the fuel filter last changed? Maybe try a different brand of fuel(Not supermarked, unless its the 99Ron super) like Shell V-Power?

Every little helps!

I'm getting 37 out of my 1.6 vvti, so I'd expect you to get more than that from a 1.4 unless you're caning it everywhere.

i get about 29 at the minute. few weeks ago was about 35mpg but ive been hammering it a bit recently cus been on late shifts and driving home on empty roads is wicked. only reset the ECU a few days ago too. mines a 1.6

[-Ish]

I got 380 out of a full tank when i bought my recent 1.4l and that was mostly motorway driving.

Could it be a heavy foot? or yh maybe it could do with a service?

[Norfolk n Chance]

My last average was 31mpg..... and that's on a T Sport!!

[reidy]

My average is 30.6 mpg on my TS

[rallyfan1986]

could be a combination of service (oil, filters and plugs) and driving style

also could be tyres, im getting 33mpg out of my tsport at the moment with uniroyals on, but with nokian winter tyres i got 35mpg and eagle f1's i got 29-30mpg

[andycam06]

what mpg did you used to get ?

as said maybe due a service,

maybe overfueling, am i way off here but doesnt the MAF sensor give trouble which would drink fuel ?

[shoney]

Im getting 29 out my CTS at the moment, most I've got is 35, I'm running a K&N filter, tyre pressures are fine and it's serviced on time, I think it may be my driving style haha

[Uber_Luke]

28mpg in the t sport at the moment.

Like the boys said - give it abit of a service check

If that fails then source a hot air feed. The opposite to a cold air feed.

Lower oxygen content. Smaller bang. Lower power. Lower petrol. More mpg.... Dunno if it works like :(

If its lagging in power your more likely to lead foot it so you'll use more

How did you reset your ECU. Could you tell me how please

I have noticed the poor motorway fuel consumption at speeds over 70mph. This is because the engine is fairly small for a car of this size, and there is no sixth gear so the revs are quite high.

The 1.6 does better at motorway speeds however the 1.4 at around 50 - 60 mph will give you 50+ mpg in some cases

i run outa a tank in bout 400 but that was lead footing everywhere maybe little light on the gas dont need to race your self i guess coz same thing one week i drove like a nana and got 650 outa it and mines 1.6 4a-fe

[mr-p]

just checked mine and its down at 24.6 lol according to the computer, can tell the suns out

[-Ish]

Do you guys all work out you mpg or rely upon the trip computer in the car?

[shoney]

I work mine out every time I fill up, I generally got to the same pump at my local Sainsburys so its quite accurate.

Miles done divided by gallons of fuel added/used,

I use mine and occasionally work it out

Trip computer says 31.6mpg

Worked sums say 30.6mpg

[-Ish]

ill reset mine and see how much i get.

[d4dsr]

I'm getting 41 mpg from my 2ltr d4d sr, thats all around town, get over 60 mpg on a run, thats why I've decided to keep it for another year

[anonyx]

been getting 38mpg on the TSport without gunning it much, a few rouge overtakes and a bit of lift every now and again. I find looking ahead, high gears, never breaking and maintaining slow and steady acceleration helps.

How have you worked that figure out??

Only ask as the highest mpg i've had was 41mpg on a long motorway journey....

There's no way round town i'd get near that figure

The best I've had is 38mpg and that was one long slow motorway run
