What petrol do you use ?

Only super,ideally bp. Its not just the octane but the ethanol level....

I noticed earlier that now that the 3 or so litres of diesel that i put in the other day have been burnt off the 97ron that i topped up with is causing pinking...I normally always use Tesco 98ron and never hear any rattling...I very rarely change the garage where i get my fuel but had to as it was ram packed due to a price drop that happened at the weekend...

Occasionally i put a bottle of redex in and some octane booster..Works a treat....
