I'm getting 44 mpg commuting from Nottingham to Leicester using Shell Diesel Extra,before then getting 41 mpg on Sainsburys City Diesel.

I don't hang about,but neither do I cane it.

Is this consumption poor?

I was expecting a bit better.

I dont have a vRS so not sure if its good or not, but I do know that my dad gets better performance in his car with Tesco petrol rather than anything else :eek:

My previous 53-plate vRS got an average of 47.5 mpg (using the brim the tank method) measured over 8000 miles. Mix of driving, mix of branded/supermarket fuels.

Just got a brand new vRS on Tuesday, did 44mpg on it's first tank of BP.

I would say normal... you drive it quickly, and therefore use more fuel.

WHAT CAR mag did a review on how fuel consumption claim are plain wrong. The surmise that you should take the combined figure (52.3mpg in your case) and take 10% - 15% off the top (47.1mpg - 44.5mpg) respectively.

My own figures from my past cars and present, seem to fall in line with this assumption. Due to making being larger then mount everest, I need to take 15% off the top (Or maybe my driving style)

I drive a 1.4TDi Fabia with a combined of 62.1mpg, however I get 54.02mpg average over 1000 miles using 'THE FILL TO BRIM METHOD' as stated in this thread (The only true way to get a figure) which is a drop of 13.0% to date, I have had the car for 3 weeks and just done 1,000 miles in it.

Though this is a geeky answer I hope it sheds a little light on the matter

Q

However the computers seem to vary. On my octavia the computer tends to overestimate by about 2 mpg, around 3.5%.

I'm averaging around 44 mpg on my 6 month old vRS (with 17000 miles!!!yipes)....computer says 56mpg!!!

Yep, same trouble with the computer on the Fabia.

Computer says 55mpg, spreadsheet and brimming method says 44mpg!

It really depends on temperatures, how much you get stuck in traffic, how hard you accelerate. I can get >50mpg easily if I try, mostly doing easy 40+ mpg if not caning it but making good progress.

Fuel economy did improve for me over time, and the LPG injection helped too (not like that will pay for itself in that way though)

i'm getting 55mpg at present , so i think you must have a very heavy right foot

Sorry to have to say this but Trip computers, like the manufacturers. Who currently regulate the "Official" figures.... simply lie !!!

Use this method: -

1. Fill car to top (When the cut out happens on the pump)

2. Reset Trip Odometer

3. Drive like normal

4. Repeat Step 1

5. Calculate - mpg = Miles/litres x 4.54609

6. Repeat above steps to gain average over time.

You will find that Trip computers lie, the only true way to do it is 'Physical Investigation'

Hope this helps those who rely on lies.... !!

Q

Was getting an average of 43 mpg, then i switched tyres from Toyo's to Michelins and now I am doing 47 mpg average (Not mesured from computer). Shame they don't grip as well :(

Cool insight..... have to do more miles then get some Michelins for my 1.4TDi.... I was planning too, but with this info I will definately get them next Thanks

Q

Thats where your improved mpg is coming from, the michelins obviously have less rolling resistance (static friction) with the road surface. Static friction is basically grip!!! Have you noticed a difference in road noise levels in the cabin??

I bought my vRS in August & I've done 4000 miles since then ,filling to the brim every time & recording the quantities.When I bought the car it was fitted with nearly new Toyos,the noisiest tyres I've ever experienced.I never realised Shellgrip was so noisy!

Maybe I'll slow down a bit with the onset of winter & when Michelins replace the Toyos it'll be a bit more frugal on the juice.

All of this anal retentive number crunching does not detract from the fact that the Fabia vRS is the finest car I have ever owned,it'll do me for a good while yet.

What can I say... I am anal.... maybe I should have been a beuracrat Like Hermes on Futurama... :rofl:

Q

just done that , and have done that for over 2 years , last fill put in 45.07 litres using vent release method , had done 553 miles , so that is 55.778 to the gallon , current overall average shown on trip computer is 55.5 , i think this diesel engine is the only one which will get near the manufacturers laboratory tested consumption figures

In that case your're either a very good driver.... or simply one lucky G.I.T.... :rofl:

have done 630 miles on a tank , having filled up in France with Shell diesel , had to put over 50 litres in to fill it up though

I'm gonna have to try this vent release method!! I'm liking the sound of over 500miles between fillups!!!!

As a former Shell worker I will state that going over the automatic cut out of a pump is DANGEROUS, there needs to be a considerable empty space to allow for natual expansion of the fuel.... also to prevent explosion and escape of fuel in the case of an accident. I have said my peace here but it is upto you after all. Please take this advice and be safe

Might be just being silly but what is the vent release method?

Might be just being silly but what is the vent release method?

if you look down the inside of the filler neck ( on the right ) you will

see a shiney nipple sticking out ........ this is spring loaded and if when

you have filled the tank to the cut out ...... you can press the nipple

in and release air from the expansion .. this then allows more fuel into

the tank ( if you listen you should be able to hear the air escaping )

do this several times during the fill up and you should get at least

another 3 to 5 litres in the tank ... I use this method every time I fill up..

BEWARE I would not recommend this for Petrol cars unless you are

going straight out on a journey ..... cos petrol expands in warm weather

but does not seem to affect diesel ....... Due to my short traffic laden journey

to work ..... I am only getting about 35mpg :thumbdwn: :thumbdwn: :thumbdwn:

dont take any notice of the computer readings . they are only inacurate guidelines

for the true mpg ..... you need to brim the tank and take the mileage then brim again

HAPPY MOTORING

My Fabia TDi 100 estate was getting about 55mpg on 185/60r14 Michelin FuelSaver tyres (and i must be lucky - the on board computer is pretty accurate) but this dropped to 51mpg when I changed to 205/45r16 Bridgestones. TBH the Michelins were terrible for grip - the car is so much more positive now, and the traction control gets less of a workout.

Just had it chipped to 131bhp - let's see what that does for economy!!!!!!!!!!

My trip computer was reporting 42mpg for my first weekend of ownership. Needless to say, I wasn't exactly hanging about! This morning on my run to work, I got a combined 57mpg! (50% small roads/housing/industrial estates 50% motorway) I fill each time and calculate my mpg so it should be interesting to get a real world figure.

Not sure if I should say this but I did a full to the brim and tried to get as much as possible in to make sure as I couldn't believe that it was full.

450miles and returned 65+ mpg on a 2001 TDi estate. I know the milage was right may have been a bit more so I am erring on poor consumption. The fuel was exactly
