I know that the standard approved aviation oils are mineral oil based and require the ash-less dispersant qualities. I know that the zinc in typical automobile oils does harm to our air cooled Lycomings and Continentals. Out of curiosity, with so many oil formulations out there, does anyone know of an automobile, truck, marine motor oil that does not have zinc and is ashless dispersent?
