Certainly no production problems here and its £1.13 also.
I wouldnt use any other fuel bar V-Power. Fill a tank with V-Power and Tesco 99 and V-Power you'll get more miles for one and most mappers prefer to map on V-Power also.
V-Power is seen more of a hard driving/race type fuel where as Tesco 99 is seen as a more greener.
Performance wise ... who knows, you need to map both on the same RR and see what you get. Id reckon V-Power would give more gains.
