Just done my weekly consumption check, and it was an unusual week in that I did a one day 160 miles trip as well as the usual 35ish per day, so around 280 miles this week. The consumption on my 1.4 petrol was just on 40mpg for the week.
Best yet, but I am becoming convinced that the engine management systems on new cars is controlling consumption etc. and holding it down for around the first 5K miles; which I just happen to have recently hit. It was the same with both the last two cars, an almost step improvement at 5K. Has anyone else come across this?
I am approaching the 5k with my 1L Ecoboost, so will keep an eye on it. I am getting 40+ now, with mixed local driving, including a learner who keeps forgetting to change up and who has only just realised you can use 5th gear @ 40mph providing you don't accelerate or climb a hill lol.
Thought I better check exactly what the mileage was only to find it was now 5210! So, I did not notice any change at 5k
A month ago, I did Worcester to Crewe (M5/M6) , speed a steady 65mph, mpg 40, outside temp 6 degrees. Return journey at same steady speed mpg was 47 but outside temp was 18 degrees.Is temperature significant or was it because when going north you go uphill lol.
Today with more miles on the clock I did 50mpg so it is improving - mine is 1.0 litre 100ps.
by the way fill up your car first thing in the morning or late at night when the air is cooler and the fuel is denser -- you get more mpg! Well technically anyway.
My bias has around 3500 miles on the clock. I achieve advanced driver on the Eco mode but still do not achieve the stated fuel mpg. Does this improve over time. Current mpg is around 40mpg depending on urban cycle
Thanks Gracow, should have realised that myself but was suffering from driver lag. Finished my journey south, 1124 miles at 67.4 m.p.g. Long delays around Luxembourg and the entry to the autobahn in Germany. Disel engine growls a bit over 80 m.p.h., may check my oil level in the morning !!!
12k miles, mixture of: full load; driver only; long haul; town work; aircon on max; convenience rules so cost not important means foot down whenever; 5th gear at 40mph in any conditions; recorded average = 39.6mpg. Quite possible that short haul outweighs long haul.
On long haul average mpg goes up and on short haul, never drops below 39.6 no matter how driven.
On full tank system says 360 miles possible. Petrol @ 127.7/L and 44.41L = 15.75p per mile at todays prices.
I have a 1.6 Tdi and am pretty consistently averaging 54 mpg which is less than some owners are reporting. However the vehicle came fitted with a set of Continental Premium Contact tyres which are optimized for grip and use a rather soft compound. They seem to be wearing quite rapidly and when I replace them with low rolling resistance tyres I would expect at least another 5 mpg
For the record tyre fuel efficiency ratings go from A (best) to G (worst) and the Continental Premium Contactsare rated 'F' while the Eco Contacts have a 'B' rating
