well from what i have researched this is what i have picked up on each fuel from everyone.
BP Ultimate - GOOD lol
Caltex Vortex - Mixed opinions, few horror stories
Shell V-Power - Good although octane drops alot quicker and leaves u with a dirty rear bar.
Mobil Synergy 8000 - Same as vortex
I have heard mobil do not have any ethanol in their fuel, is this a good or a bad thing?
