https://chempol.co.uk/en/product-category/pcmo-gasoline/ The efficiency and longevity of modern engines are crucial. To do this, anti-wear additives are among the most effective means. These special chemicals are formulated to minimize friction, prevent metal-to-metal contact, and improve overall engine performance. Of particular concern is that the wear rate increases exponentially with high pressure and temperature. Therefore, it is necessary to add additive friction modifiers and friction modifier additives to engine oils. This article will discuss the role these additives play, the advantages, and their necessity for modern engine maintenance.
