Beware of Diesel Additives
Many additives for diesel fuel are on the market and when added to a fuel tank they will supposedly deliver a number of positive effects. These include cleaning the fuel injection system, improving combustion and enhancing performance. It is unclear which, if any of the additives, actually do what is promised.
What is clear is that using such additives does present some risks as the composition of these additives is generally not listed on the packaging and so you don’t know what is being added to the fuel system.
Reactions, some of which may not be desirable or described by the maker of the additive, can occur when these treatments come into contact with other lubricants such as engine oil or with engine components.
Furthermore different diesel fuels have different additives and oil companies do not disclose what these are, so there a likelihood of incompatibility.
Bosch does not recommend or approve of any diesel additives and the use of these may affect warranty.
