2021年3月12日 · It’s short for Research Octane Number, a measure of the petrol’s octane rating. In Australia, the octane ratings top out at 98 for premium unleaded, before stepping down to 95 premium unleaded, E10 (94 octane) and standard 91 octane unleaded. The octane ratings of petrol available elsewhere may differ.

Higher octane petrol like 95 petrol is designed to burn more efficiently and produce more power compared to lower octane petrol like 91 octane. If your vehicle's engine is designed to run on higher octane fuel, using 95 petrol can result in better acceleration, smoother idling, and overall improved engine performance.

2025年2月21日 · While 92 petrol is more affordable and appropriate for most standard vehicles, 95 petrol is necessary for high-performance cars with turbocharged engines or modern engine technologies that require a higher octane rating to perform efficiently and avoid knocking.

2024年1月2日 · 91 petrol has an octane rating of 91, indicating a lower resistance to knocking, while 95 petrol features an octane rating of 95, providing a moderate resistance to knocking. 98 petrol has the highest octane rating among the three, offering superior resistance to knocking.

While 95 petrol offers a higher octane rating and potential performance benefits, it comes at a higher cost. If your vehicle requires a higher octane rating to prevent engine knocking or optimize performance, 95 petrol may be the better choice. However, if you are on a budget or do not require the higher octane rating, 91 petrol may suffice.

The main difference between 91 and 95 petrol lies in their octane ratings and performance characteristics. While 91 octane is suitable for most vehicles, 95 octane offers benefits for high-performance engines.

2017年4月29日 · You drive into a gas (petrol) station and fill your car’s tank with 91-rated fuel—unleaded, of course. There’s no way you’re touching that E10 or E20, they’re dodgy and will mess with your engine!

2025年1月12日 · 95 octane fuel is often used in more modern engines that have higher compression ratios. This fuel offers better resistance to premature ignition, which is important for engines that demand more power. It strikes a balance between cost-effectiveness and performance, making it ideal for mid-range vehicles and those with moderate performance needs.
