28-32mpg.

Audi 80CL, best was 39.9mpg, when I was driving it like I stole it (one of many false alarms with No3 kid - from M4 J12 to M4 J16 no-one overtook me!)

The V Power definitely has more "oomph" in it.

In the 100, I drive 96 miles a day, steady A roads.

With 95RON, I cruise on the 1st butterfly, but need to use the 2nd butterfly to overtake (you can feel this in the accelerator pedal - the spring resistance is different - bit like a twin choke weber).

With 97/98RON (V Power or BP Ultimate), I can cruise and overtake without using the 2nd butterfly.

I have tried this day in and day out, up and down the M4/M5 when I was working in Gloucester last year too. Very repeatable conditions. Filling up every 4 days.

I'm been using Micky's old 100 for the past few days for work and am getting between 36 and 38mpg.
9 miles each way to work but about 7.5 of it is motorway which helps!

I have found injection cars will run on any unleaded but carb cars will need 97ron other wise they will pink under acceleration .

thanks for the info. now i must figure out how to post pictures up here, so u can all have a look at my pride and joy!:nod:
