Took my girlfriend from Bedford to Luton airport this morning down the A6 at breakneck speeds to catch an 8am flight.
I decided to return home on the M1 and see how high i could get my mpg level to. I reset it leaving the airport and, after a mile tailback, joined the motorway. I drafted a Miller lite lorry all the way to Junc 13 at 54 mph (OH, THAT WAS BORING) followed by an uneventful run in on the A421... the result was a truly amazing 36.5 mpg average with a peak at 37.6 mpg... this from a V6. I was gobsmacked....
Anyone ever get a higher reading than those?
Daft I know but what else do you do when your girlfriend goes away for 2 weeks???

You do realise we are going to get "spotted" reports of Avantimes causing massive holdups everywhere now.
Never mind.. a colleague of mine has an Mercedes SL550 AMG. He gets about 5 mpg out of that!
" My current Avantime and my last one both did the same "
Some connection here me thinks !
My exhaust has just started a blow. I think that's dropped the mpg reading by a couple of mpg. Hopefully it will improve a tad better than the original when I go stainless.
Incidentally, are you sure you are in 4th gear at 70mph? I've checked with the revs and proved I'm not, but going into manual shows 4th gear on the display, so it kicks back a gear if you shift to manual. My auto usually changes to 5th gear at about 46 mph, but with c/c set for 50mph motorway roadworks, I often find it kicks into 4th for no apparent change of circumstances. I just select manual and push back to 5th.
Another technique is "pulse and glide" (I haven't tried this on the Avantime)i, but that is allegedly quite an efficient way of doing it. You need a quiet road with not much traffic, and then you accelerate up to the speed limit in top gear (the "pulse"), then release the accelerator and coast with the car still in top gear (the "glide"). When you are "gliding" in a modern car, the engine uses no fuel at all.
Of course, that's very annoying and possibly dangerous to do in traffic! But you can use part of the technique when coming to a stop - lay off the brakes for as long as possible and use a "glide" to slow down.
Don't forget though that the Avantime has some considerable mass pushing it along. It's something that could really benefit from a hybrid system to take the energy back from the brakes..
I think Roger means 30 mpG!
Other times I have had good results one way and poor coming back - I think this was down to a tail/headwind...
Now I dont really bother
Cheers
97 octane fuel, I never use less, as I get terrible "Pinking" with the 95!!!
