The S3 is needing to be topped up with super unleaded so went to local garage to fill up full to be confronted with ALL super nozzles blanked off and message saying S/U will not be delivered for a while as they are having problems getting it. Apparently theres a few garages like this in the Edinburgh region.......Now the problem is I have 15 miles left on the DIS which means slightly more and I have to drive thro Penucuik to get home. If the S/U is off aswell there I dont really wanna be topping up with normal 95 RON fuel or should I use and pop in some octane booster.....Its a 20 mile drive home aswell. What would you do????
