Petrol Octimax 1L

49.00 + Vat

Petrol Octane Booster 1L



1L Petrol Octimax

Petrol Octimax Is an additive that ensures that any concerns over fuel quality are eliminated and that even the branded fuel is top-treated to achieve a more enhanced performance. Petrol OctiMax has a number of benefits to users with petrol cars and is a specialist fuel additive designed to boost the octane rating of unleaded petrol in order to satisfy the demands of high compression ratio, high performance engines.

  • OctiMax fuel additive boosts 95 RON regular petrol to 97 RON
  • It boosts 97 RON super petrol to 99 RON
  • It improves acceleration and provides smooth power delivery
  • Suitable for high performance petrol engines

1 Litre Petrol OctiMax Treats 2,000 Litres of petrol. Ideally mixed in when filling the tank

Dosage can be measured to suit the quantity of the petrol being treated 


Octane is a measure of petrol’s resistance to ‘knocking’ which is sometimes referred to as ‘pinking’. Knocking is due to the fuel/air mixture igniting under compression in another area to that started by the spark plug. The knock sound we hear is shock waves travelling around between the piston crown and cylinder head as the two burning mixture zones collide. Knock can occur due to a variety of factors such as high compression pistons, combustion chamber/piston crown deposits in older engines or ignition timing that is too advanced. Increasing octane often reduces ‘knock’. The problem is very common in engines with a high compression ratio often specifying the old 5* fuel.

Octane Booster

In addition to performance benefits, increasing the RON with an Petrol OctiMax octane booster can also provide added protection for your engine. By minimizing knocking, it reduces stress on vital engine components, helping to prevent potential damage and extending the engine’s lifespan. This is particularly crucial for high-performance engines or vehicles that are subjected to demanding driving conditions.


An octane booster can provide increased fuel efficiency. By promoting more complete combustion, it allows your engine to extract maximum energy from the fuel, minimizing wastage. This means you can go farther on each tank, saving money on fuel costs and reducing the frequency of refuelling stops.
