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.

Well, as at today I've achieved 402.3 miles, with a possible 35 miles indicated range. I have a jerry in the trunk, I'll put that in tomorrow. In theory, it may be possible to cover at least 20 miles more, but I'm not keen on running completely dry, and stalling on a major road.

I managed 30mpg on the drive back at 65mph.

I'm looking into LPG too as I can't afford that everyday.

I have a 3.7 QS and the best that i have had with a very light right foot is 37-38 on a motorway run at about 60-65 that was about 100 mile run. I always use V power , Not that there has been alot around Leiecster over the past few weeks . I picked some up when i was in the South over the weekend.

South East has no v-power still either - south west did when we were down there, but went in the 'wrong' car just in case! Had to fill the S8 with 95 in the end as fed up trawling Shell/BP/Texaco in the faint hope one of them had had a delivery!

Apparently Shell took the decision to prioritise 95 and std diesel deliveries to their sites at the back end of March and I assume that will continue until any threat of strike is withdrawn.
