Statements are being made about performance gains from the file used. This quote from Shell: "Surprising but true, despite the vast amounts of technical effort spent developing a Formula One car, the fuel it runs on is surprisingly close to the composition of ordinary, commercially available petrol."
The components and knowledge set has been around for many years relative to F1 fuel. It is hard to believe that the gains come from within this old knowledge set. Has there been recent advances in science that allows the puzzle pieces to be assembled in new ways?
Specifically.. within the limited selection of chemicals available to F1.. what chemical combination in the fuel provides friction reduction for the piston rings?
