[00:00:01]98 GOOD FOR EVERY CAR.

[00:00:04]>> NO, NO, NO. Ever wondered what 91, 95, or 98 RON means at the petrol station?

[00:00:11]RON stands for research octane number.

[00:00:14]It tells how resistant the fuel is to engine knocking. Knocking happens when fuel burns at the wrong time inside the engine. This can reduce performance and harm the engine over time. Higher RON fuel is harder to ignite accidentally, which is useful for high compression or turbocharged engines. But if your car is designed for 91 or 95 RON, using 98 may not give extra power. You may just be spending more. Every engine is designed to run on a suitable octane number. The manufacturer sets the correct RON based on compression, timing, and engine performance. Always follow the fuel rating recommended in your owner's manual or fuel cap. Use the right fuel, protect your engine, and save your money. Follow RNF Drive for simple car knowledge.
