Did you know… drivers in Singapore spend an average of more than S$20,000 on petrol for a single car in a 10-year period? Back in the days, drivers only had two options: Petrol or diesel. Skip to today, not only can you visit different petrol stations to purchase petrol from your preferred brand, you also have different types of petrol to choose from.

At Tiq by Etiqa, we want you to have the best driving experience by providing Private Car Insurance and services like e-Cleva. We go one step further by providing this guide to choose the best petrol for your car. Knowing the types of fuel can help you save money, drive more efficiently and prevent engine damages. But first…

What’s a RON?

You always see it. The multi-coloured red, yellow and green pumps. But what are the differences between these types of petrol? The colours have no significance as they can change at different petrol stations. It’s the number you should be aware of.

Processed fuels carry a Research Octane Number a.k.a. RON which determines the fuel’s anti-knock quality. This is the fuel’s resistance to pre-ignition – how efficiently the petrol can ignite and run the engine. The higher the number, the better the octane rating. The best octane rating for your car can be found inside the fuel cap or in the car’s manual.

#TiqOurWord Octane is a chemical used to prevent the fuel from prematurely igniting from sources other than the flame of the spark plug. Learn more about spark plug and other car parts here.

RON95 is the standard petrol suitable for almost all types of automobile. It is the most common octane rating for a petrol fuel, which also means it is the best option at any budget. This type of petrol is perfect if you use a low-powered vehicle or only travel short distances on local roads.


Despite its price, RON98 can improve your driving experience significantly. RON98 prevents knocking – when fuel ignites too quickly and damages the inner engine components. It helps clean the engine and your car consumes less of it since only little is needed to produce combustion. This can improve acceleration and give you a smoother ride, making it suitable for turbo-charged engines such as those in high-powered or sports car.


RON92 is one of the cheaper and older petrol types. It is suitable for less powerful cars. Even though it is less popular and not many petrol stations sell it, it can be the best choice when you’re on a tight budget. However, lower RON also means the fuel can cause deposit build-ups, which can harm the engine over time.

If you noticed, diesel produces black soot. This is due to the carbon compound not being burned properly, making it the least efficient option on this list. There are different types of diesel such as synthetic, biomass and petroleum diesel – with petroleum diesel being the most common. Do note that diesel fuel can damage non-diesel engines.

Only you know what’s best for your car

RON98 typically costs S$0.30 to S$0.40 more than RON95 – a whopping 15% difference in price! You can save money on petrol by using RON95, or purchase the more expensive RON98 and then save money on car maintenance in the future.
