SYN-ESTERTM GY-500 is a lubricity additive. It is expected to be less susceptible to bacterial attack than conventional fatty additives. It provides excellent lubricating properties and high load-carrying capability as a mineral oil, sulfur and chlorine free solution. SYN-ESTERTM GY-500's low degree of unsaturation means it does not cause staining and has outstanding thermal, oxidative and hydrolytic stability for high-temperature performance. Being ashless, it burns off cleanly.
