[QUOTE="oscar, post: 169062, member: 2757"] it's a placebo effect. unleaded premium offers no power increase on your car, that's actually chemically impossible luke :) octane rating (95 RON, 97 / 98 RON = Research Octane Rating) is to do with the detonation point of the fuel itself. so if you're running a high compression engine, and plan to soup it up ; example, neil with his cams and much higher power output will want to use 97/98 RON to avoid the fuel igniting earlier than normal. at high revs when the engines hot, using 95 RON usually results in pre-ignition where it goes bang earlier than it should due to engine temperatures. going from a 95 RON to a 98 RON will allow your cars ignition timing during the mapping process to be advanced or retarded further than what will be achievable on 95 RON which is why you usually get more ''power'' once mapped, but this is all to do with spark or ignition timing. it will also protect against higher flash point temperatures, which is the temperature at which the fuel goes bang i just seen the advert on the telly dave lol :D these advert folk could sell a sand to the arabs!
