Ashless dispersants are chemical additives commonly used in lubricants to prevent the formation of sludge, varnish and deposits. They are called “ashless” because they burn without leaving any residue or ash. Dispersants are substances that help suspend and disperse insoluble particles or contaminants in fluids, preventing them from settling and causing harmful effects. Characteristics of… Read more
