- 2020 CX-5 Signature Azul Metalico
In all the write ups and reviews or the 2019 Signature Turbo I've run across they say you can use high test for 250hp or regular for 220hp output. Interestingly on my Colombia delivered vehicle the yellow warning sticker inside the gas cap doors says "Use 95 RON octane" with no mention of lower octane regular being an option. The Premium gas in Colombia and some other South American countries is rated at 95 and regular at 91.5 (according to Wikipedia). Also according to the latter Premium fuel in most US states is 93 octane. Looks like up to 100 in many European countries and Aral Ultimate at 102 in Germany. Wonder why US models can run on regular. Different tune?
