Real world mpg

Even between V-Power & Ultimate my last car got about 30-40kms more per tank using V-Power, I'm going to trial a few tanks of each to see which fuel gives best mileage.

I filled up with normal Shell before we left but that is mainly because Shell is regarded as good & I get points but when we left Liverpool I drove round for ages (near the Runcorn Bridge area) & could't find a garage then used Asda fuel - no difference in the consumption.

I know we are all a bit unhappy with the MPG we are getting, as there nothing like the LR figures. But isn't this the case with all makes & models.
I had a Ford Kuga to dive today. its not in a par with the Evoque by any means, but is the same size vehicle so i thought i would post my MPG.
Ford figures are 47MPG, the best i could get after driving 300+miles on A & B roads was 36MPG

Likewise I have an base Enterprise-renta-car 2.0TDI Kuga - front wheel drive, that I've done 700+ miles in the last week in, driven gently it's averaging 39.6mpg on 150 mile motorway/A road runs as an ED4 equivalent that's not exactly brilliant either. To be fair to the Kuga it's pretty OK to drive though.

You need to run a few tanks of the same fuel to see improvements, as the ecu will gradually adapt tuning.

No this is not the case.

My last scirocco i averged 37mpg the combined figure was 42.
My 07 civic type r i averaged 32mpg, the combined figure was 32mpg
my banger 2001 ford mondeo i averaged 34mpg, the combined figure was 38mpg

All a hell of a lot closer to the manufacturers claims than i get with the evoque where i am 14mpg short of the published combined figure.

If you do the research, you'll see that the test routines to establish published figures are far removed from real world driving where things like the number of engine starts, anciliaries switched on and so on make a difference. To everyone who whinges about their consumption not matching the published figures I ask this question: You do keep the aircon and stereo switched off, don't you?

My Si4 has settled to a reasonable 28 - 29 mpg on a run - 500 miles to the Lake District and back and that's with the aircon on and Adele singing her heart out.

I hardly ever have the aircon on so thats not the reason.

Im suprised your car isnt burning more fuel in protest at having to endure the whinging cacky sack that is adele playing through its stereo.

The June edition of What Car? magazine tells exactly how the Euro Official figures are calculated - it's all done in the lab on a rolling road, the car never goes near a real life road.

I rarely have the aircon on either to be honest but as I said in my earlier post my consumption wasn't bad on the journey I last did.

The handbook recommends that the air con and 'auto' be left on as a 'default' setting,. I had assumed that the actual cooling function (requiring the compressor to run) would only operate when the internal selected temperature could not be achieved using cooler air from outside, and that the air con would not actually run other than in hot weather. Is this not the case? If it is cold, and presumably the air is being warmed rather than cooled, what is the air con doing? Does the heater consume electricity? (I had assumed it was the normal type of heater which operates off the engine cooling system, and that the heat was therefore 'free').
