Does the CX-90 require premium fuel?

According to Mazda's official technical specs, the Skyactiv-G turbo engine powering the CX-90 in Malaysia can run on regular RON95 petrol, but the automaker recommends using RON97 or higher octane fuel for optimal performance. Here's why: high-compression turbo engines like this one benefit significantly from higher octane ratings, which effectively keep in check harmful knocking. This allows the engine to fully deliver its rated 246PS of peak power and 450Nm of torque. For Malaysian CX-90 owners, sticking with RON95 long-term won't necessarily damage the engine – modern ECUs are pretty good at adjusting for knock. However, you might notice slightly blunted acceleration response and so-so fuel economy, especially noticeable in our hot climate or during spirited driving when the engine's working hard. Interestingly, Petronas' RON100 racing fuel is technically compatible, but let's be real – for everyday driving, RON97 hits the sweet spot in terms of performance versus cost. The actual per-kilometer difference between fuel grades depends on current pump prices and how your mileage might vary. My advice? If you're mostly doing city commutes, RON95 is a solid, wallet-friendly choice. But if highway cruises or that extra surge of power matters to you, splurging on the good stuff is worth considering.
