Which fuel do you buy for your Aston Martin ?

I did wonder whether ethanol would be mentioned, and I think you are the first to do so Craig.
For my classic cars, I have always use non-ethanol petrol, purely because of the widespread damage to the old type rubber components used in the fuel systems.
I had thought there were no adverse effects of any type with modern cars.
It therefore was a surprise to me, hearing Michael Beake's opinion, about a reduction in optimal engine performance under full throttle. Although some AM engines have anti-knock sensors which make adjustments, it sounds as though there is no adjustment when 5% or 10% of the fuel is less combustible (if that is the correct word).
ESSO premium is used for my classics, so I will now use that petrol for my AM. Additional cost, but many of us do low annual mileages, so relative.
Tim pointed out the regional refinery aspect. I cannot remember, but I think there might be a geographical area, where the ESSO branded fuel does contain ethanol.

I started this topic wondering whether there might be a discussion about ethanol.
The consensus though appears to be that octane is probably more important.
Petrol now contains 5% or 10% ethanol, but original petrol can still be obtained.

My understanding is that in the UK, regular grade petrol must now contain 5% ethanol.
Most higher grade petrol does contain 5% ethanol, except ESSO Synergy Supreme+ which in some/most/all areas of the UK, does not contain any ethanol.
10 % ethanol I believe is now in some petrol on mainland Europe.
Pumps are labelled E5 or E10.
It seems that the label displayed on ESSO Synergy Supreme+ pumps, can be ignored.
