Ah, I didn't know that. Not particularly a fast car (although it is quick for what it is), but all EU cars are made to run on 95 RON fuel. Anything lower than that and most cars would run pretty lumpy I would have thought, with them pre-detonating the fuel/air mix.
We should all get Mr Fusions installed on our cars. We should all own and drive DeLoreans, too.
Or maybe not.
Ah, but the Mr Fusion only powers the time circuits and flux capacitor, the internal combustion engine still ran on conventional gasoline. Unless, of course, you were referring to us all popping back to the 80s for each fill up.
Sorry, far too late to this thread, but the movie nerd in me couldn't leave it unsaid. :)
