Würth Petrol Performance Improver is a 300ml fuel-system treatment for petrol engines with or without a catalytic converter, designed to clean deposits, protect against corrosion and help maintain efficient combustion.
Added directly to the fuel tank, the treatment helps remove lacquer-like deposits, resin build-up and oxidation residues from the petrol fuel system. It is suitable for E10 petrol and is particularly useful as preventative maintenance or where deposits within the fuel system may be affecting engine operation.
