Dozer said:Does the number on your fuel equate to its octane rating like ours does? 95 and 98?
It does, but USA/Canada pump fuel is numbered using the AKI = anti-knock index (RON + MON)/2 system, but many countries including the UK use RON numbers, so US 91 is approximately equivalent to UK 96 octane.
