Ever topped up your tank with a mix of RON 95 and RON 97 petrol? Wondered if it might damage your car? You're not alone! This is a common concern among drivers. But fear not, mixing these fuel grades is perfectly safe for your vehicle.

Understanding RON Levels

RON (Research Octane Number) indicates a fuel's resistance to knock, which can damage engines. Higher RON fuels can handle greater compression before igniting prematurely.

Mixing with Confidence

Modern cars are equipped with knock sensors that adjust ignition timing to prevent knock, regardless of minor variations in octane level. So, mixing RON 95 and RON 97 won't cause any harm.

Maximizing Efficiency

While mixing won't damage your car, using the octane level recommended by your manufacturer is ideal. Check your owner's manual or the label inside your fuel door. Higher octane fuels might not offer significant benefits in most everyday vehicles designed for RON 95.

Fuel Dilution and Strategy

Running your tank close to empty before filling with a different octane can momentarily dilute the new fuel's effect. To maximize the benefit of RON 97, consider filling when your tank is half full.

Beyond Octane: Consider Additives

Some high-octane fuels contain cleaning detergents that can benefit your engine over time. If you're looking for performance or cleaning benefits, consider using a fuel specifically formulated for that purpose, rather than relying solely on octane level.

Don't stress about accidentally mixing RON 95 and RON 97 petrol. It's perfectly safe for your car. However, using the recommended octane level and exploring fuel additives might offer better engine performance or cleaning in the long run.
