Fuel consumption - MPG - S5 TII

[DKWW2000]

We all are aware that our cars by virtue of the engine are not renown for their fuel efficiency so I have been monitoring mine. A trip to RRG & back was a good journey to find out what I am getting.
The trip was mostly motorway except J6 to Shelsley Walsh, in Total 322mls. I used 12.3 gals (56 ltr) -:- 4.55 = 26.1 mpg which at a steady speed of ?? mph. Much better than I thought, FB is about 30+

26.1 is pretty good for a 13B Turbo I reckon. it's been a long time since I worked out my consumption in a FB but I seem to remember it was low to mid 20's

Impressive. I remember being appalled by the fuel consumption of my S5 turbo back home. This was compared to a 12a bridge port on a Nikki with mechanical secondaries which meant I could cruise round on primaries all day so I could return 30 mpg without too much trouble (but not a lot of excitement).
Maybe an o2 sensor was bad or some such thing on my FC? You should be well pleased with your result.

When I daily drive my t2 cab I recall 20-25mpg average from it including short journeys. The fb was similar, the FD was 12-18mpg though....

is it a uk thing ?

ive never taken note on any of my cars for mpg, especially rotary engined

unless its going through lots more than usual, indicating an engine fault etc

How would you know if its using more if you do not know what is normal?
Just another bit of information on driving habits/engine health/tuning always handy for owners/new owners as a bench mark.
As someone once said......."You do not know what you don't know until you know it"
