Fuel experience

Well I only use BP Ultimate because a BP servo is handy to me. I don't think running another brands 98 fuel would be detrimental. Just make sure it's from a servo that looks like they would sell a bit of 98. What you want to avoid is old fuel from a servo that might only sell 1 tank of 98 a week.

I use all three major (BP, Shell and Caltex) but 98 RON only. Evoque has more 'energy' and gives slightly better economy than 95 RON. I think quality fuel is more about the actual Service Station rather than the Brand.
