Its petrol, not magic dust. What it will do is governed by RON ratings and BS Nos. You need to get it from somewhere that sells a lot because the forecourt tanks tend to be cleaner, and it is a good idea to stick to the same type which saves the ECU from having to do much adapting. Specialist fuels do genuinely return measurably improved performance/mpg on highly stressed engines but Mr Average is unlikely to be able to detect the long-term difference - and ALL reports show that improvements, particularly in mpg fail to match the extra cost.
and with all that said what is your point ?? i have to run atleast 98ron becuse of supercharger and here in sweden V-power 99ron is the same price as 98..not a difficult choice right.
