This is a new fuel brought out by shell. Its the first 100 octane petrol sold in bowsers. They use a 5% blend of ethanol and is to be used by the v8 supercars next year. When Dick Johnson was interviewed about it, it came across as the fuel didnt help power figures too much at all. They seemed more focused on environmental benefits but to be honest I'm not too sure the difference between 5 % ethanol and 0% ethanol will do for the environment. Also its about 14c a litre dearer than normal unleaded. I've tried running it for a couple of tanks and i can't see why i'd start using it over BP ultimate.
If anyone has anythoughts or opinions feel free to post them.
