Yes, it’s true, a tested and proven workable fuel additive like Green Plus liquid combustion catalyst should be used as it provides a more complete burn resulting in significantly less pollution.

Carbon deposits form in every gas and diesel engine. These deposits are THE major contributor to SOx, NOx, CO, Particulate, and unburned hydrocarbon emissions. Use of the right fuel additive can ELIMINATE hard carbon deposits and prevent their reformation. Once deposits are eliminated, there is indeed a corresponding reduction of polluting emissions.

Hard Carbon deposits will NOT burn out of an engine at temperatures less than 1200 degrees Celsius, unless the proper fuel additive is used.

Detergent based additives are very limited in their efficacy as they do not cause the agglomerations to combustion, but they cause them to slough off into the internal workings of the engine. They will them hopefully be carried away by the oil.
