Does the additive reduce the sulfuric acid action of the sulfur in fuels?
A. It can reduce sulfuric acid action such as white sulfate salt at the end of the tailpipe, but only to a certain extent. Sulfuric acid action caused by by sulfur-laden fuel cannot be eliminated; it can only be curtailed. The reason for this is when sulfur in fuel is burned, sulfur dioxides are the end product. Condensation of sulfur dioxides with another combustion product (water) forms sulfuric acid.
