E10 vs E5 in the UK
E10 is now the standard petrol for most vehicles in the UK, while E5 remains available mainly as a higher-octane option.
If your vehicle is compatible with E10, the relevant question is usually not whether it exists, but whether the price gap to E5 is justified for your driving pattern.
What to check
- Your vehicle compatibility guidance
- The local price difference between E10 and E5
- Whether your journeys are routine enough to optimise consistently
