Then you're stuck with >5% Bio-Ethanol. Probably even after a Brexit

Our super is 97 or 99. Some 97 is currently ethanol free, all 99 is circa 5% ethanol.

Doesn’t matter what the EU say and doesn’t matter if we are in or out, the UK Government will find a way to make our standard even stricter than the EU standard anyway!

Which 97 Ron is ethanol free? That’s the one I’d use for sure. Always thought that the V-Power was?

I have driven at least a million miles using supermarket fuels and do not believe there is a problem with the stuff. It is also clear that the branded stuff does produce more power and economy. Our Perodua was vastly better on the super unleaded as is my Panda Twinair. I am not convinced the difference is as notable if running around locally as it is on long high speed runs. i did a back to back test a few years ago and recon Standard Esso gave 5 mpg more than Tesco fuel. As it was a company car however I went for the clubcard points. As my car is designed for cheap fuel I am not convinced about use of the better fuel. It would be interesting to do a rolling road test of engine power and look at engine temperature on the different fuels too.

Vpower is 99.

There are ever shrinking parts of the country where ethanol free 97 is available. I wouldn't want to guarantee it, as most fuel suppliers will pull stock from a number of different terminals / supply points.

(The exception being V-Power as it's specifically made for Shell, whereas 97 Octane is available from more or less all terminals)

Tried Esso Supreme + 97 other day. Wonder if that ethanol free as car flew. And that was with weight of a full tank. Though Panda has ticked over 500 miles since oil change. Something unlocks am pretty sure. As every time get it back feels a second or so off to 50 in 3rd.

Pretty sure, in that part of the country, it'll have Ethanol in it. I could be wrong, but it looks like stock will be sourced from Phillips 66 at Teeside.

After 2 tanks of Shell and Texaco 95, put Texaco 97 in at my nearest station that does super unleaded. Throttle pick up doesn't improve instantly through the rev range. But the low speed 2nd gear knocking noise through drivetrain at 10mph has gone as it always does. Only saved £3-£4 with cheaper stuff. As done purely motorway miles since Wednesday afternoon, economy worked out at a record for this particular car (44.1mpg). Foot to the floor locally expect this to drop by a third next week.

It can take a good few miles to notice any real difference between fuel grades as the ECU adapts to your throttle inputs and the readings from the various sensors.
