About E10 Unleaded
E10 became the standard petrol at UK forecourts in September 2021, replacing E5 as the default pump grade. The "E10" name refers to the ethanol content — up to 10% renewable bioethanol blended with petrol. It has a 95 RON octane rating and meets British Standard EN 228.
E10 is the fuel most UK drivers should use. It is the cheapest petrol option, widely available at every forecourt, and compatible with the vast majority of cars on the road.
E10 vs E5: Which to Choose?
If your car is compatible with E10 (most post-2011 vehicles), use E10 — there is no benefit to paying 15 to 18 pence more per litre for E5 super unleaded unless your car specifically requires a higher octane rating. For the full breakdown, see our E10 vs E5 complete guide.
Where to Find the Cheapest E10
Supermarket forecourts (Asda, Tesco, Sainsbury's, Morrisons) consistently offer the cheapest unleaded prices, typically 5 to 10 pence below branded stations. For tips on reducing your fuel bill further, see our guide to saving money on fuel and our fuel savings calculator.
Frequently Asked Questions
What is E10 unleaded petrol?
E10 is the standard grade of unleaded petrol sold at UK forecourts since September 2021. It contains up to 10% renewable ethanol and has a 95 RON octane rating. It replaced E5 as the default pump petrol.
Is my car compatible with E10?
Around 95% of petrol cars on UK roads can use E10. As a rule, cars manufactured from 2011 onwards are compatible. Older vehicles should check the government's official E10 compatibility checker or use E5 super unleaded instead.
Why is E10 cheaper than E5 super unleaded?
E10 is the standard grade and is produced in much higher volumes. E5 super unleaded has a higher octane rating (97+ RON) and lower ethanol content, which costs more to produce. The price difference is typically 15 to 18 pence per litre.
Does E10 give worse fuel economy than E5?
Slightly. Ethanol has less energy per litre than petrol, so E10 reduces fuel economy by roughly 1 to 2 percent compared to E5. However, this small difference is far outweighed by the 15 to 18 pence per litre price saving.
