Cut a long story short, I work for Tesco and the company have decided to have a massive overhaul of the 99ron fuel. 1.Massive Sponsorship campaign with Rallys....ok no-one cars but.... 2. If you local Tesco PFS has 97ron, it's being upgraded to a 99ron one within the next couple of months. First major roll-outs will start this coming Sunday night, with the North-East and North-West having the major initial roll-outs ( mostly due to the fact dan saff already have 99ron ). Finally!
