Guide to fuel.

You see posts all the time on social media, asking what is the best fuel type for their bike.

The United Kingdom provides a wide range of fuel options, including petrol, diesel, hybrid, electric, and various alternative fuels. This guide outlines unleaded fuel in detail, highlighting their respective benefits and limitations to enable a thorough evaluation.

By understanding the unique characteristics of each option, you will be better equipped to make an informed and strategic choice when purchasing a vehicle.


When choosing unleaded fuel for motorbikes, consider the following:

  • Regular maintenance checks and paying attention to the fuel you use can help keep your motorcycle running smoothly and performing well for years. By sticking to these simple habits, you’ll ensure it stays in great shape over time.
  • Octane Rating: Always use the fuel grade recommended in your motorcycle’s owner’s manual. Higher octane levels (like 91–93 AKI) are best for sport and turbocharged models.
  • Ethanol Content: Be mindful when using ethanol-blended fuels (E10). Older motorcycles can be more prone to ethanol-related corrosion, which may cause engine damage. If your bike is older or sits unused for long periods, it’s better to opt for ethanol-free (E0) or E5 premium petrol.
  • Fuel Quality: Regular unleaded petrol is a popular choice, but premium fuel can provide better performance for some high-end motorcycles.
