Wurth petrol treatment additive 300ml can, can be use with or without catalytic converter, Removes coating and resin deposit in the fuel line, petrol pumps, carburettors, valve tips, valves and injectors. Also removes oxidation residue, prevents water which is produced in the fuel tank by the hygroscopic characteristic of E10 fuel. Wurth is a brand can be trusted, made in Germany. I had few petrol engine cars until few months back, so I bought a few stock of these, now that I have electric cars, so no longer use of them. I used this product as an internal engine cleaner, one tank a bottle is sufficient for 1000 to 1200 mile, improves efficiency, reduce wear tear in the engine. Set of x2 bottles VERY GOOD PRODUCT FOR PETEOL ENGINE. HIGHLY RECOMMENDED.
