MG's official E10 statement
As published on the UK government E10 checker, reproduced word for word. Checked 25 October 2026.
There is no compatibility information available for older MG’s up to 2005 when the company ceased trading. It is therefore recommended to use E5 petrol.
The MG brand has returned more recently, but no compatibility information is available. Owners should contact their dealer, the manual or filler flap for further information.

If your MG 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 MG and E10
Can my MG use E10 petrol?
MG has not published E10 data for the UK checker. Use E5 unless your manual or fuel flap says E10 is fine.
What if I put E10 in an older MG?
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 MG?
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 MG?
Look for an E10 label inside the fuel filler flap, check the owner's handbook, or ask a MG dealer.
