Nulon Pro Strength Octane Booster (PSO) is specifically formulated to increase the octane rating of petrol used in high-performance and competition engines. High-performance, high compression engines require fuel with a higher octane than normal passenger cars.


Using a fuel that does not have a sufficiently high octane rating causes the engine to detonate (ping), which in turn can cause severe engine damage. Every engine has a minimum octane requirement (OR) that depends upon engine design, in particular compression ratio. The higher the compression ratio, the higher the OR. If the petrol used does not have a sufficiently high Research Octane Number (RON) to cater for the engine’s OR then detonation occurs.


Detonation is the term used to describe the chemical breakdown of the fuel/air mixture which results in premature selfcombustion during the compression stroke of the
engine, i.e. the mixture explodes prior to ignition by the spark plug. Under these circumstances the force of the explosion is opposing the direction of rotor travel, resulting in enormous loads. If detonation is allowed to continue, engine failure can occur. Nulon PSO substantially increases the RON of petrol, thus reducing the likelihood of detonation. Nulon PSO is compatible with all leaded and unleaded fuels including race fuel and Avgas.


  • Boosts RON by up to 7 numbers (70 points)
  • Stops engine detonation (pinging)
  • Maximises horsepower potential
  • Reduces overheating and piston damage
  • Safe for catalytic converters and oxygen sensors
  • Components are US EPA approved

Indicative RON increases:
91.5 Unleaded +PSO = 96.5 (5.0 RON increase)
95 PULP +PSO = 98.1 (3.1 RON increase)
98 PULP +PSO = 100.1 (2.1 RON increase)
96 LRP +PSO = 98.5 (2.5 RON increase)
(When used at the maximum recommended treat rate.
