HDMO

Heavy duty diesel motor oils (HDMO) also known as heavy duty diesel engine oils (HDEO) are designed to meet the needs of diesel trucks and off road equipment operating in sustained high load and high temperature conditions. 

HDMOs are developed with specific benefits in mind that are useful to commercial and industrial applications. HDMOs are designed to reduce the wear and viscosity changes due to contaminants and to minimize the downtime for equipment and vehicles.
