Must be good for the mpg. How many mpg do you now get with the 50 mph limit on most roads please.

Hi there,

I was getting an indicated 61.4 mpg after doing a steady-ish 50 mph for about 120 miles of congested motorway with a bit of a load on. Given the over-read on the IPK, that's probably about 59 mpg. The more stopping and starting you do, the less you get, of course. This little experiment is a good case in point - over 718 miles, my average speed was just short of 50 mph (IIRC it was 48.4) so with braking, traffic, higher speeds at times etc, 54-ish is more realistic.

Cheers,

Simon.

The most you can reasonably expect to achieve is low to mid 50s and that is a manual car cruise enabled, driven at 60MPH without traffic, and automatics driven with the same conditions 46mpg at a push.

Anyway if you want to make yourself feel good about fuel consumption, reset the MPG meter while travelling downhill and tickle the throttle, you might see an impressive figure then.

60 MPG may be seen as an instantaneous figure, but it is not a realistic one

During 2018 my remapped cdti auto has achieved 48.4 AVERAGE dividing 5200 miles by the gallons purchased. I am happy!

Regularly get over 600 to a tank on the CDT manual. It's easily 12-15 mpg more frugal than the Auto.

I have found if you can get over 200 miles from brimming to three quarter tank on the dial, you are going to get around 700 miles from a tank full easy.If you only get 200 when half a tank indicated, you are not getting many miles to a gallon.Thats in a diesel of course.
