Forums Forums Enthusiast Forums A - Z Autowirral 76 miles, and used quarter of a tank

What causes a car to use so much petrol, its had new airfilter, oil change, new plugs, new throttle housing, new exhaust, new tryes.
There is no fuel leaks.
I dont go speeding.

So why a quarter of a tank for 76 miles

Dont sound too bad, were you driving like you nicked it?

I dont do speeding

what sort of mpg do you normally get? I normally get about 60 miles to a £10 on a 1.4 newish astra varies between 30-40mpg depending on how i drive it

60miles to £10, i wish i could get that, £10 gets me about 30miles

hang on, what car you got? So it would cost £100 to fill your tank and get 300 miles?

£70 to fill it from empty, its only a 1.2 and it guzzles it, the last time i filled it i got 320 miles out of it, b4 the light came one

Mines about the same for normal town driving better on motorway bear in mind you've still prob got 70-80 miles left when light comes on if its £70 to fill a full tanks around 52 litres which gives you around 11.5 gallons to the tank and an mpg of around 35 mate I wouldn't say that's too bad?

Depends on your driving style and what type of driving. A lead foot will always guzzle the juice. Motorway cruising will give you a lot better mpg than town centre, stop/start, rush hour traffic.

On motorway cruising I can get high 40's but around town sometimes it can drop to 15-20mpg, maybe lower.

Are you measuring the 1/4 tank from full? My tank appears to drop very quickly for the first 1/4 - 1/2 then levels out as it get close to empty.

Do you try to drive economically or does your car control consist of stop, go, left, right?.

Do you drive everywhere in 1st?.

I would struggle to get such crap mpg out of a car that small. Mine would go about 80 miles off just a tenner.

no measuring it from when i fill it to quarter

its all stop start round town etc etc

I mean varying amounts of accelerator combined with a lot of costing along in gear when going down hill or when the lights ahead are red etc. Letting the engine slow the car over a distance as aposed to just swapping between stomping on the accelerator or the brake straight away.

A sensor sounds knackered, try the air flow meter, coolant temperature sensor, lambda sensor. I'd go with the lambda first. More money eh?
