When classic cars are not used on a regular basis, or especially when they are stored during winter, the fuel is an important topic to consider. Fuel additive from Porsche Classic helps – with the “Made in Germany” quality you expect.

The fuel additive forms a protective layer between metal and fuel. This is a gentle process that protects the tank and fuel system against corrosion and deposits – even the areas that are not covered by the fuel, such as the air zone in the fuel tank. Special molecules in the additive form a corrosion protection layer throughout the fuel system, thus ensuring an optimal level of protection. Condensation that has already formed in the fuel system is bonded by the chemical elements and does not cause any damage.

The additive dissolves deposits and adhesions that have already been formed. We were able to prove this in several long-term tests in collaboration with the Porsche Development Centre in Weissach. A number of tests to determine the compatibility of the additive with materials that form Porsche Classic Genuine Parts were also successfully carried out.

The 300ml of Porsche Classic fuel additive is sufficient for fuel tanks ranging from smaller ones such as the 50-litre tank in the Porsche 356 up to larger tanks with a capacity of 90 litres, such as in the Carrera GT. The fuel additive remains effective for stationary periods of up to seven months and its performance only begins to gradually decline after this length of time.
