Wagner Bactofin fuel conditioner (250ml)

Classic cars tend to be used occasionally, and the ethanol content in modern petrol/gasoline is problematic for the whole fuel system. In this episode I explore a fuel preserver from Germany that Roger at Classic Car Workshop has identified that's of real interest to classic car owners.  He's established Serpentine Fuels to act as sole UK importer of Bactofin and other Wagner products.
