Octane quality is one of the many properties of fuel that is often associated with power and improved engine efficiency that is measured by the international standard for fuel, RON.
RON95 helps us to have better environment. For Example, Petronas Primax 95 meets Euro 2 emission standards and has reduced sulphur content of 500 ppm (parts per million), which makes it better for the environment
What is RON?
Answer : RON stands for Research Octane Number rating for unleaded petrol. It determines the petrol`s `anti-knock` quality or resistance to pre-ignition or detonation as it burns in the combustion chamber. Knocking occurs when the fuel-air mixture in the cylinder explodes instead of burning in a controlled way. This shockwave moves within the combustion chamber, and creates a metallic `pinging`. It measures the combustion properties of the fuel.

What do the numbers 95 and 97 mean?
Answer : The numbers 95 and 97 represent the minimum RON value of a fuel that will prevent “engine knocking”.
What is “engine knocking”?
Answer : Engine knocking happens when fuel combusts prematurely before ignition by the spark plug, which causes a “knocking” effect, resulting in loss of power. Using the appropriate minimum RON fuel that is recommended by your vehicle manufacturer will ensure that combustion happens at the high time to avoid “engine knocking”.

| Volvo engines can use RON91 to 98 RON unleaded petrol. Volvo Car Malaysia says that for best performance and lowest fuel consumption, RON98 (or closest RON) is recommended. For normal driving, RON95 is acceptable and RON91 should only be used in cases where RON95 is unavailable. Knock sensors in the engines will adjust the engine timing to prevent damage with very low RON fuel. |
