miles per gallon

[darrenjoe90]

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 ?
