If your car's fuel tank is labeled for E10, it means that your vehicle is compatible with ethanol-blended gasoline containing up to 10% ethanol. In this case, you should choose the appropriate petrol grade that is also labeled as E10.
E10 petrol is typically available in various octane ratings, such as 92, 95, or 98. The octane rating refers to the fuel's resistance to knocking or pinging. You should choose the octane rating that your car's manufacturer recommends for optimal performance.
Check your car's owner's manual or consult the manufacturer's guidelines to determine the recommended octane rating. If the manual specifies a range, you can generally use any E10 petrol within that range. If you're unsure, you can usually find the recommended octane rating on a label inside the fuel door or near the fuel filler cap.
In summary, if your car's fuel tank is labeled for E10, choose a petrol with the appropriate octane rating (92, 95, or 98) that is also labeled as E10, and follow the manufacturer's recommendations for the best performance and fuel efficiency.
