• Boundary lubrication


  Seen where there are regular start-ups and stop-ups and where shock-loading conditions are present. Oils have high-pressure (EP) or anti-wear (AW) additives to help protect surfaces where full film cannot be achieved
• Mixed lubrication


  A cross-section between boundary and hydrodynamic lubrication. Most surfaces are separated by a lubricating layer but asperities are still in contact
