If your Mazda can't use E10
Use E5, sold as super or premium unleaded. Any car that runs on unleaded can use E5. If you have already filled up with E10 by mistake, don't worry: one tank won't harm it. What to do after the wrong fuel →

Questions about Mazda and E10
Can my Mazda use E10 petrol?
Mazda lists which petrol cars can use E10. Check your model and year in the list below.
What if I put E10 in an older Mazda?
A single tank in a non-approved car will not cause damage, according to UK government advice. Fill up with E5 next time and keep using E5.
Where do I find E5 for my Mazda?
In the UK, E5 is sold as the "super" or "premium" unleaded grade (97+ octane) at most larger filling stations. Check the E5 label on the pump.
How else can I check my Mazda?
Look for an E10 label inside the fuel filler flap, check the owner's handbook, or ask a Mazda dealer.
