car do feel abit slower after I filled up with normal unleaded about 2 weeks ago.....any advice please..

 

What model is it? Fuel varies and does degrade after a time. You can get a bad fill up sometimes. Nothing you can do other than use the fuel up. Take it easy and don't go blasting around too much if you feel the fuel is 'bad'. Try filling up with Optimax next time!

 

Either pump the fuel out our buy a whole bottle of octane booster & put the whole lot in & drive below 3500 until the fuel is used..........

 

import bugeye.... cant wait to empty the pump..
