They all returned the same mpg, give or take.

"give or take" ...

The big one on the left should not be used in conjunction with the small one on the right, if fuel consumption is a concern.
As an aside, my 1800 saloon, was indicating 42MPG today.......awesome

Good advice - better advice from an mpg pov is get a car with 3 pedals...

I shall get a diesel emissions report next week. Our works van a 1.3cdti Vauxhall returns 52mpg might try the same tests.

That'll likely also return a similar mpg - until everything is clogged up again...

Couldn't agree more.
My own experience has been mostly with Shell ultimate (other premium fuel brands are available but with no guarantee of performing the same). On my regular commute (26 miles each way - same traffic each week, different weather). Running mostly premium fuel but occasionally sainsburys fuel. Consistently worse mpg (2 - 4 mpg) and didn't always run as smoothly. Never once did the Sainsbury fuel give better mpg than the Shell ultimate. And that is over 7+ years. Calculating the extra fuel cost against mpg also came out comparable in pence per mile most of the time as well. So for me it's proven that paying more for fuel doesn't have to mean a higher cost per mile.
