Default miles per gallon

Today i went for a drive to the land that time forgot (scotland) and did just over 360 miles. i got an average of 28.1 mpg. That was a few miles round town, then about 30 miles of country roads then the rest motorway. I think thats pretty good for an S8. Although the other day i got an average of just over 30 mpg driving like a judge going to sheffield. does everybody else get about the same ?
Also fuel costs. i thought they were supposed to be going down or staying the same ? wednesday i paid £135.9 per litre and today i had to pay £139.9 from the same garage. whats going on ?

That is some drive. Never seen 28 as an average on any S8. Perhaps your Revo map has improved things? Not sure about the price, I don't even look anymore.

Managed 29-30 on a run upto the lake district last year, sitting on the motorway at a steady 70 all day long.

Get about 21-22 on my daily a road commute.

Thumbs down

my computer is pretty much stuck at 14.5 at the moment with lots of very short local journeys.

Get 22ish on long runs
