Optimax

All info comes from Evo edition 087 so I make no claim to the verasity of their claims:
They claim that the following results are the highest to lowest: Golf Gti Turbo test car
Sunco Racing fuel: 218 bhp and 248 ft lb
BP Ultima: 212 bhp and 252 ft lb
Tescos: 212 bhp and 242 ft lb
Optimax: 209 bhp and 242 ft lb
BP 95 ron: 204 bhp and 242 ft lb
Shell 95 ron: 205 bhp and 234 ft lb

Tescos 99 ron is 5% bio-ethanol, giving higher octane than super hence 99 ron........... Racing fuel is quoted as 115 ron

Here endeth the lesson........... how boring is that.

Funny enough BP call their diesel Ultima and their super unleaded Ultimate............... Evo obviously were running the golf on heavy oil not petrol
Sunco has the same rating as Avgas........ piston engine aero fuel.... used to run my rally car on the stuff... last count Sunco was 315p a ltr, Avgas is currently 138p ltr........ same as my local garage is charging for pucker four star........
