Millers Oils CFS 5W40 Motorsport Engine Oil - 5L

Part of the Competition Fully Synthetic range of engine oils, the CFS 5w40 incorporates Millers Oils’ original NANODRIVE low friction technology. The oil is formulated with 100% synthetic base fluids, including a blend of three esters combined with additive technology for maximum performance.

The CFS 5w40 is suitable for fast road engines, and for use in races, rallies, sprints and hill climbs. It’s ideal for engines with hydraulic tappets such as the Ford Zetec.


The CFS 5w40 is designed for use in competition or modified engines where maximum power release is the preferred criteria. It has been formulated for high revving engines used in circuit racing or for larger engines used for a shorter duration (i.e. hill climbs and sprints).

The oil is suitable for operating at 125°C with peak temperatures up to 150°C.

  • Lubricant film is more resistant to 'shear' and viscosity loss in high stress areas
  • Greater load carrying capacity than mineral oil
  • High film strength for ultimate protection
  • Outstanding cold flow properties for reduced wear at start up
  • Excellent thermal stability and oxidation resistance
  • Provides the optimum balance between hydrodynamic and boundary lubrication and the power absorbed through pumping losses to ensure maximum power release

  • Manufactured to far exceed the requirements of API SL/CF and ACEA A3/B4
  • Ideal for fast road or track day use, particularly in engines where a 5w30 is normally specified
  • Suitable for operating at 125°C with peak temperatures up to 150°C
