All gasoline additives are considered to be toxic, except for perhaps alkylate. Nevertheless, refiners must continue to provide higher octane fuels with tightening economics, tighter environmental controls, and lower quality feedstocks. As there are many commercial octane enhancers available, the relative merits of these additives need to be compared. We have performed an evaluation of the effect of using octane improving additives in fuel from three Saudi Arabian Refineries on gasoline produced in the Kingdom. These additives such as iron and manganese alkyls, unlike lead, have no reported adverse effects on the environment, and manganese additives have a proven performance record with respect to engine performance, automobile maintenance, and octane improvement ER -
