Carina Bretschneider ASKED THE GUIDE

Unleaded fine

IT'S stated on the fuel cap of my Mazda6 that it needs 95 RON fuel and that it is suitable for ethanol E10. Can regular unleaded be used? If so, what are the consequences?

E10 FUEL usually has a higher octane rating than fuel without ethanol, and the E10 on the market has a minimum octane rating of 94 RON, which is suitable for your car. You can use regular unleaded, which has an octane rating of 91, but you will lose performance and your fuel consumption will increase. There is no affect on warranty.
