The study of antifriction properties of different calcium sulfonates has been carried out in a wide temperatures range. It was revealed that the alkalinity increase improves the antifriction properties of these detergents due to the formation of a protective film with higher uniformity on the friction surfaces, and this effect is the most evident at high temperatures. Calcium carbonate, which is contained in the additive, plays the main role in the formation of a protective film.
