RON : Frequently Asked Questions

What is RON®?

RON (Research Octane Number) is a rating of petrol. It determines a petrol’s ‘anti-knock’ quality or resistance to pre-ignition or detonation as it burns in the combustion chamber. Knocking is an abnormal combustion and should be prevented as it is damaging to the engine.

What petrol is sold in Malaysia currently?

Service stations in Malaysia currently retail petrol products of RON92 (Silver with Techron at Caltex) and RON97 (Gold with Techron at Caltex). At the moment, vehicles requiring RON95 and below are also utilizing RON97.

What vehicle types are able to use RON95?

Most vehicles are able to use RON95. However, it’s best to refer to the Original Equipment Manufacturer’s (OEM) recommendation in your car manual or check the back of the petrol filler lid of your car for the recommended octane rating.

(i) I am a RON92 consumer. Won't switching to RON95 damage my vehicle's engine?

The main difference between RON92 and RON95 is their octane ratings, indicated by the number in the product name. Using petrol of a higher RON will not hurt your car. You just need to find a suitable fit for your car and driving style. It’s best to refer to the Original Equipment Manufacturer’s (OEM) recommendation in your car manual or check the back of the petrol filler lid of your car for the recommended octane rating.

(ii) I am a RON97 consumer. Won't switching to RON95 damage my vehicle's engine?

The main difference between RON97 and RON95 is their octane ratings, indicated by the number in the product name. Using petrol of a lower RON may or may not hurt your car. You just need to find a suitable fit for your car and driving style. It’s best to refer to the Original Equipment Manufacturer’s (OEM) recommendation in your car manual or check the back of the petrol filler lid of your car for the recommended octane rating.

Should I empty my car's petrol tank before refueling with RON95?

This depends on the amount of remaining petrol in the petrol tank. The smaller the amount, the faster you can derive the benefits of RON95.

What is the effect on the performance of the engine if petrol of a different RON is mixed together?

It is not recommended to mix different RON levels as this might result in sub-optimal performance. For example, if you have added a lower-than-recommended RON in the mixture, this can result in knocking and can cause a loss of power.

What is the impact of RON95 usage on the environment?

At present, there is insufficient data to adequately prove that a higher or lower RON grade poses an environmental issue.

Do I have to always pick the highest octane rating petrol for my vehicle?

The highest octane rating may not necessarily be the best for your car. You should choose a suitable fit for your car and driving style. It’s best to refer to the Original Equipment Manufacturer’s (OEM) recommendation in your car manual or check the back of the petrol filler lid of your car for the recommended octane rating.

Does a higher RON indicate a more environmentally-friendly fuel product? How about greater power?

The true difference between the grades of petrol lies in an engine’s requirement. This does not guarantee a promise of greater power or a more environmental option as the number increases. This infers that cars using RON products greater than their engine requirements may not be necessarily gaining better performance than if they adhered to their car Original Equipment Manufacturer’s (OEM) recommendations.
