Both modern cars and older vehicles have specific requirements, that have a chemical solution to provide the optimal engine performance and driving comfort. Modern fuel systems are highly tuned and therefore more susceptible to the negative effects of chemical reactions in the fuel. These lead to fouling of the fuel system, lack of lubrication, corrosion and other problems. Older vehicles experience problems to obtain the correct air/fuel ratio and combustion efficiency due to accumulation of deposits in the fuel system and wear on the components.
