Engine Lubricants Technical Committe

Achievements

The CTLM has researched many topics in the course of the last few years:

  • Impact of engine lubricant on fuel consumption
  • Lubrication and low temperature viscosity
  • Lubricant/elastomer compatibility
  • Two-stroke engine lubrication (motorcycles)
  • Impact of lubricant on oil consumption
  • Detergent additive and anti-wear interactions
  • Ring sticking in diesel engines
  • Impact of lubricant on valve train wear
  • Oil thickening in diesel engine
  • Oxidation (laboratory and engine) tests.
