The debate over whether premium petrol is better for your car has been ongoing for years. Some drivers swear by it, while others believe it’s a waste of money. To determine the truth, it’s essential to understand the differences between premium and regular petrol and when it makes sense to use each.
Key Facts
- Fuel Recommendation: It is generally recommended to use the type of fuel that the vehicle’s manufacturer recommends. Using regular petrol in a car designed for regular petrol will not negatively impact its performance. However, using premium petrol in a car designed for premium petrol can help the car perform better and avoid potential engine damage.
- Octane Ratings: Premium petrol typically has a higher octane rating compared to regular petrol. Regular petrol usually has an octane rating of 87, while premium petrol ranges from 91 to 94 octane. Higher octane ratings make petrol more resistant to “knocking” or “pre-ignition,” which can occur in high-performance engines with higher compression ratios.
- Performance Engines: Performance engines, especially those with higher compression ratios or turbochargers, may require or benefit from the use of premium petrol. Premium petrol can help maintain performance and fuel economy, reduce the chance of engine knocking, and potentially avoid costly engine repairs.
- Manufacturer Recommendations: It is important to consult the owner’s manual or check the fuel recommendations provided by the vehicle’s manufacturer. The manual or fuel door may indicate the recommended octane rating for optimal performance.
- Mixing Petrol Grades: It is generally safe to mix premium and regular petrol in the same tank. Modern vehicles with advanced fuel monitoring systems can adjust to different petrol grades. However, there is no benefit in putting premium petrol in a vehicle designed to run on regular petrol.
Fuel Recommendation
The type of fuel recommended for a vehicle is typically specified by the manufacturer. Using regular petrol in a car designed for regular petrol will not negatively impact its performance. However, using premium petrol in a car designed for premium petrol can help the car perform better and avoid potential engine damage.
