I recently brought a 2005 Ghia. All the reviews were saying 50+ urban mpg, but im only making 52 and I live in the country. Theres no harsh breaking, its a 15 mile journey and i only sit in traffic for no more than 5 minutes, and thats slowly moving. Average speed is 50mph, so I cant understand why I am only just getting the average town mpg when its almost all country miles I do!

Am I changing gear wrong?! This is my first diesel and I am trying to learn the noise of the engine when it needs changing. Am changing at around 2500 revs. The turbo seems to really kick in at 2500 in 2nd, but cant feel it at any other time.

Any suggestions on how I can improve my mpg?

Thanks everyone

Hi Sezimodo
Speaking from limited experience as I have only had the car (2004 1.4 TDCi mk6 4Door Ghia) a few weeks and, as I always do, brimmed the fuel tank when I got it then after 322.3 miles brimmed the tank again and got 52.62 m.p.g. That is mainly city driving. How do you check your consumption?

Kind Regards,

Stainless P.S. As you can sere I am new to the forum as well, sorry about the repeats, its like ITV innit?

turbo will always suck the fuel.. si if you can drive without turbo cutting in then you should see some increase.

personally i would be happy with 50 never trust car company figures.. its there to make sales.

Its ok Im new too! I am emptying the tank then brimming it, then doing the calculation on the mileage done and the number of gallons used. So I do the number of miles divided by the number of gallons used.

To calculate the number of gallons I am doing the number of litres put in divided by 4.5461

Am I doing this right?

True, but I have trouble telling when the turbo is kicking in. In 2nd gear i can feel it kick in at around 2500 rpm, but cant feel it in any other gear. For my last tank I have done 100 straight motorway miles as well as my regular country mileage and the mpg has come out the same and I got the same miles per tank. I've switched to changing gear when it gets to 2000 rpm to see if that helps, and it doesnt seem to

Have a look here to see how they "Get the figures" > http://www.vcacarfue...ting-scheme.asp

Also quote> Urban cycle
The urban test cycle is carried out in a laboratory at an ambient temperature of 20°C to 30°C on a rolling road from a cold start, i.e. the engine has not run for several hours. The cycle consists of a series of accelerations, steady speeds, decelerations and idling. Maximum speed is 31 mph (50 km/h), average speed 12 mph (19 km/h) and the distance covered is 2.5 miles (4 km). The cycle is shown as Part One in the diagram below.

Extra-urban cycle
This cycle is conducted immediately following the urban cycle and consists of roughly half steady-speed driving and the remainder accelerations, decelerations, and some idling. Maximum speed is 75 mph (120 km/h), average speed is 39 mph (63 km/h) and the distance covered is 4.3 miles (7 km). The cycle is shown as Part Two in the diagram below.

Combined Fuel Consumption Figure
The combined figure presented is for the urban and the extra-urban cycle together. It is therefore an average of the two parts of the test, weighted by the distances covered in each part.

Just an interesting point but look how far they are actually "driven" !! ( 2.5 miles in urban cycle and 4.3 in extra urban ) so basically i'd say your 52mpg is not to be sniffed at!

We've only had the car 1mth and we get just over 50mpg on short town journeys.
We took it to Wales the other week (250 miles) and stuck to about 60 or 70mph depending on the road and we got 59.5mpg. I'm sure it would have been better if we weren't stuck in a traffic jam for 30 mins.

I have a fiesta 1.4 TDCi . When I fill the tank I can do 7 trips to and from work average 80 miles thats about 560 miles on 45 litres. The terrain is hilly /twisty which means a lot of 3rd and 4th gear work but theres only one set of lights and i am seldom in a standing traffic. I reckon thats about 56mpg.
