Petrol Types: Which Is Best For Your Car?

Choosing the right petrol type for your car can be a hassle. From petrol costs and fuel efficiency to performance, there are many factors to consider before making your decision. Fortunately, our guide to the best petrol type for your car is here to alleviate your woes!

Read on to find out how you can choose the most suitable petrol type before your next refuel.


There are primarily three types of petrol available in Singapore, besides diesel. You can find them at any petrol station islandwide.

  • 92-Octane Fuel: Low-grade petrol
  • 95-Octane Fuel: Regular-grade petrol
  • 98-Octane Fuel: Premium-grade petrol

Petrol Knocking Combustion

The numbers correspond to the octane ratings of the fuel, which tell you how stable the fuel is. The higher the octane rating, the more stable the fuel. With highly stable fuels, your car is less likely to experience spontaneous combustion, or knock. Knocking can damage your engine over time, and mostly occurs when the fuel you use is unsuitable for your car.

Generally, using higher petrol grades is not an issue; the problem comes with using lower than recommended petrol grades.


Most modern engines are designed to minimally burn 95-octane petrol efficiently. This means that fewer and fewer new cars are suited to use 92-octane.

While 92-octane is cheaper than 95-octane, it might come at the cost of your car’s condition. If your car engine is unable to handle the excessive knocking, your engine’s condition will likely deteriorate quickly. Hence, it is advised against to use petrol that is lower than the manufacturer’s specifications.


While most cars are suited to use 95-octane petrol, some cars may perform most optimally with high octane petrol such as 98-octane. Usually, these are performance-focused cars like sports and luxury vehicles with larger engine capacities. These cars are able to burn petrol efficiently, which translates to better performance on the tracks.

While there is generally no harm in using 98-octane in regular cars, it can be expensive, and not necessarily cost-effective. Regular cars just may not have the engine to burn high octane fuels. Hence, you may be paying more for little to no improvement in performance.


So, which petrol type should you use?

Although 95-octane is the safest option for most cars, we strongly encourage you to check your car’s manual. As manufacturers take careful consideration to test fuel consumption and efficiency, it is best to stick to their recommendations. Spending more does not always mean paying for better.
