What is Octane?

  • Updated
  • Octane is an attribute all unleaded fuels have, measured by a Research Octane Number (or RON).
  • Lower-octane fuels can result in a spontaneous ignition of the fuel-air mix called ‘engine knock’.
  • Engine knock causes the engine to adjust the timing of the spark plug, in order to prioritise protecting itself from damaging over performance.
  • Higher-octane fuels can stand more compression before automatically combusting.
  • New Shell V-Power unleaded is a 99RON octane fuel.
  • By comparison, regular Shell unleaded is 95RON.
  • New Shell V-Power unleaded -the power of high octane.12
