The additive has two main effects:
The protective effect
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.

Possible impact of not using the additive:
If your classic cars are left stationary for extended periods of up to seven months, condensation can form in the fuel system. This condensation can cause various components within the fuel system to corrode. The components of the fuel with a low boiling point can evaporate, resulting in a sticky residue on the carburettor and injectors, as well as on the electric pump. After the vehicle is left stationary for long periods, the engine may no longer start, may jolt or may not fire on all cylinders.

* Data determined in accordance with the measurement method required by law. Since 1 September 2017 certain new cars have been type approved in accordance with the Worldwide Harmonised Light Vehicles Test Procedure (WLTP), a more realistic test procedure to measure fuel/electricity consumption and CO₂ emissions. As of 1 September 2018 the WLTP replaced the New European Driving Cycle (NEDC). Due to the more realistic test conditions, the fuel/electricity consumption and CO₂ emission values determined in accordance with the WLTP will, in many cases, be higher than those determined in accordance with the NEDC. This may lead to corresponding changes in vehicle taxation from 1 September 2018. You can find more information on the difference between WLTP and NEDC at www.porsche.com/wltp.
Currently, we are still obliged to provide the NEDC values, regardless of the type approval process used. The additional reporting of the WLTP values is voluntary until their obligatory use. As far as new cars (which are type approved in accordance with the WLTP) are concerned, the NEDC values will, therefore, be derived from the WLTP values during the transition period. To the extent that NEDC values are given as ranges, these do not relate to a single, individual car and do not constitute part of the offer. They are intended solely as a means of comparing different types of vehicle. Extra features and accessories (attachments, tyre formats, etc.) can change relevant vehicle parameters such as weight, rolling resistance and aerodynamics and, in addition to weather and traffic conditions, as well as individual handling, can affect the fuel/electricity consumption, CO₂ emissions and performance values of a car.
