Ron95 vs Ron97 – Is There A Difference?

Firstly, RON stands for Research Octane Number, which is a measure of a fuel’s ability to resist engine knocking. The higher the RON number, the better the fuel quality, which means it can provide better engine performance and efficiency.

Which Petrol Should You Choose?

Besides the huge difference in price between RON95 and RON97 here in Malaysia, is there really any difference to your car if you use one over the other? The short answer: no.

For most cars, you will only ever need to use RON95 petrol. Modern car engines are able to detect any premature combustion from a fuel with a lower octane rating and adjust the timing accordingly. At the very most, this would lead to an imperceptible drop in power.

Thus, high-performance cars would get the most out of their powerful engines with a higher octane fuel, but there is no detriment or possibility of damage from using a lower octane fuel – as long as it’s above the minimum octane rating provided by the manufacturer.

Low Fuel Levels Affects Engine Damage

Running on low fuel levels can cause damage to your engine, as it forces the fuel pump to work harder to pull fuel from the bottom of the tank. This can cause the pump to overheat, which can lead to a costly repair bill.

Additionally, running on low fuel levels can cause sediment to be pulled into the fuel lines and engine, which can cause clogs and damage to your engine. By regularly checking your petrol fuel levels, you can avoid these issues and ensure your vehicle runs smoothly.
