What Should I Know About Different Fuel Grades at Service Stations?

E10 is the standard petrol available at every UK forecourt. It contains up to 10% ethanol and is suitable for the vast majority of petrol cars built since 2011. This is the cheapest petrol option. Compare E10 prices in Stafford.

E5 contains up to 5% ethanol and has a higher octane rating (97–99 RON vs 95 RON for E10). It is recommended for some performance and older vehicles. It typically costs 8–12p per litre more than E10. Compare E5 prices in Stafford.

B7 is the standard diesel available across the UK, containing up to 7% biodiesel. It is suitable for all modern diesel vehicles. Compare B7 diesel prices in Stafford.

Premium diesel (sometimes called "supreme" or "V-Power Diesel") claims to offer better engine cleaning and improved performance. It costs significantly more than standard B7. Whether the premium is worth it depends on your vehicle — check your manufacturer's recommendation. Compare premium diesel prices in Stafford.

Most cars run perfectly well on standard E10 petrol or B7 diesel. Check your fuel filler cap or owner's manual. If your car was made before 2011, you may need E5 super unleaded instead of E10 — the UK Government provides a compatibility checker.
