The next logical question that you may be asking yourself – How can any additive actually survive combustion? We spoke earlier about the availability of fuel additives for a wide range of applications and how they’ve been around for many years. The touted effectiveness of these is up to the point of the engine. Or, alternatively, increasing power or reducing smoke by altering the characteristics of combustion.

For this reason, as most DPF cleaners are sold alongside these fuel additives, it is sometimes wrongly suggested that DPF cleaner additives can’t possibly work because they cannot survive combustion due to the assumption that they are no different in content.

However, the truth, as previously discussed, is that any credible DPF treatment fuel additive will have an extra ingredient of a FBC (Fuel Borne Catalyst). These are different to the standard fuel additives, because they do actually survive combustion in their active form.

This means that they can perform their function of soot-clearing in the exhaust system and the DPF, where standard Fuel System Cleaners will not be effective in this area as they are destroyed in the combustion chamber.
