my fuel consumption again

andrew · Post by **andrew** » Sat Oct 26, 2002 6:00 pm

Im still concerned with my fuel consumption.

DOes this sound right? because it does not to me.

I have used half a tank of petrol and the needle is on the half way mark
and done 127 miles. This is in a 1.6.

Ive done motorway and city driving in that too.

Definately not! Only for a few mins in the morning when it was majorly steamed up .. apart from that i dont use it.

I drive a majority of motorway miles but however through 2 road widening works where the speed limit varies from 40 to 50mph and some town driving on my daily run. and return a daiily average of 45mpg unless I''m steamed up and it drops to 38mpg. I find that feathering the throttle boosts the economy figure a bit but I also am alarmed at the short tank range (average 320 miles before the Warning comes on) then I have to endure the widely documented refuelling problems.

especially when I average 400 miles a week

Well it is only a small car. My Fiesta's warning light comes on between 280 and 320 miles, depending on how heavy my foot's been.

the fiesta tank is smaller than the 206 tank as well mind.

127 miles on half a tank?

Hmmmmm.... here's my penny's worth.

The gague is notoriously inaccurate so on mine, realistically it'd be more like 2/3 of a tank!!!!

Are you filling it to the top? When the nozzle clicks, let it settle then you'll get another couple of litres in.

I fill my 2l up, trip it, then fill it up again and see how far I've gone on how much - usually Â£31 and 300 miles, with about 2/3 around town and the odd bit of clogging it (so the computer reads 11mpg) and the other 1/3 at 80mph (I mean 70!) motorway driving.

Any help? Yeah, I'd say your mpg is poor but don't know what to suggest?

I dont know what to do .. im gonna work out what im actually getting manually, ive taken readings of how much fuel I put in .. and how manymiles ill be doing before I next fill up. This will prove once and for all if it is bad or not.....

Then if it is, its a trip to the dealer, who still have not called me about my replacment switch !! aand I still have not had the marks sorted on my dash board.... utter rubbish dealer .... I'll be travelling the extra miles next time to buy I can tell yoU!

Yeah, but so is the engine ;-)

Sounds quite similar to my consumption, which works out about 280-300 a full tank, thats if i fill it up to the top. Also depends on your driving style

You'd be surpised. I do lots of miles in the company Mondeo. My average fuel consuption can vary from 15 to 40mpg for a single journey. The current Average MPG determines the number of miles to go so a change from 30 to 20mpg might explain the change you saw. Althought I would hope the algorithm the trip computer is more complex than that they can't realy see into the future. I often miles to go increase by many miles when I get onto motorway. The distance the fuel low warning light comes on varies fom 60 to 3 miles. I don't see this a a malfunction just the limitations of maths.

Humm i drive like a grandmar, i should get 50mpg !!! ehhehe, err no seriously, i dont rag the thing .. I rearly go over 2500 RPM. Got a quarter of a tank left .. then time to make some calculations

I rearly go over 2500 RPM

surely you are not being serious with that statement ?

andrew · Post by **andrew** » Mon Oct 28, 2002 11:49 pm

Err very serious, with city driving, which is what I do the most, why is there any need ??? Over 3000RPM is excessive and I would leave most other cars standing. 2500 works quite nicely.

Derek · Post by **Derek** » Tue Oct 29, 2002 12:18 am

didn't know you did mainly city driving although i don't expect to help your consumption.

and if you work out how to do 130mph below 3000RPM can you let me know.

cheers
