Hi, just wondering if you could advise me which grade of petrol for this vehicle and is this entirely because of compression rating?
Thanks
Bill

This car is designed to run on 91. Compression ratio has a bearing on octane ratings, although in recent times we've seen advanced engine designs and intelligent engine management systems that can deal with 91 octane fuel in very high compression engines (eg: Mazda's SKYACTIV engines run a 13:1 compression ratio on 91 octane fuel).
