As a small follow-up from my earlier post, I finally managed to do a motorway only fuel check. It was a petrol station start and finish journey of 250miles.
The journey unfortunately featured quite a few delays there and back, with a lot of slow crawl traffic at times.
The trip computer came out with 67mpg as a figure, but interestingly it was being more conservative than the actual fuel use reality.
The measured fuel use calculation came out as being 70mpg! That was also with a car full of people and luggage.
It also means I may have hit nearly 80mpg in the past as the highest trip number I have ever got was 76mpg.
