Hi All,
Has anyone got definative figures on wether Optimax DOES make a difference..? I've been running it my 02 S3 since new but finding it increasingly hard locating Shell garages so have to plot my trips accordingly. I'm thinking of going back to the usual unleaded. At the moment I'm averaging around 27.8mpg but do drive hard.
Cheers in advance.
