I thought I'll post this on both forums.
Shell Optimax is to be replace be V-Power very soon. The UK version of V-Power will be 99ron and not 100ron which is seen in other countries. All Shell Retailers have been invited to a launch day at the end of the month.
Shell are in the process of running down stocks of Optimax to a level where V-Power can be mixed.
I'm not sure when the official name change will be, but it will be a lengthy process to change all signage on sites, update all IT equipment and the Optimax signage on tankers will need to be removed or replaced. It will probably remain similarly priced to Optimax.
Shell also plan to release V-Power Diesel in the UK, its a high performance diesel and the same which was used by Audi at Le-Mans.
