Went mazda today
New Mazda 3 is coming into Msia this July with 1.5cc NA 130k++ 2.0cc NA 150k
But both varients are using current skyactive G engine as skyactive X requires higher Ron than Ron97

Last time i read about Skyactiv X, it was designed for lower ron fuel.

Not too sure about all this fuel talk, RON95 vs RON97. I was told that some cars especially cars with Turbo engine work better with RON97, hence RON97 is recommended for cars with these engines. It is not that one cannot use RON95 with the cars though I'm not sure on the after-effects if using RON95 with cars which are claimed to "require" RON97. One of such car is the Ford Focus 1.5 Ecoboost.

Also, from my own experience, not all RON95 fuel are similar despite some who thought otherwise. My Proton Preve Turbo shows knocking sound from the engine during acceleration with Petronas RON95. The engine knocking sound is like the sound you hear from very old cars >15 years. However, with Caltex RON95, there is no knocking sound from the engine. I have verified this with long-term experience when using Petronas RON95 for a considerable period (1 year +/-) and then switching to Caltex RON95(for 2 years) and then back to Petronas RON95. The knocking sound is not existent with Caltex RON95 but came back instantly wonce I pumped Petronas RON95.

Only with specific cars. I did not experience any issue with my other cars when switching between Petronas and Caltex RON95.

It is interesting if the new Mazda 3 Skyactive-X would require higher grade fuel to work and is the main reason they may not be brought in to Malaysia just because RON95 or RON97 isn't suitable for the X engine.

The above article indicates that Bermaz is not giving us the real reason for not bringing in the Skyactiv-X engine. The engine is designed for Ron 91 minimum and there is nothing mentioned about other fuel quality requirement. Bermaz's real reason may be there is no viable price slot for the Mazda 3 Skyactiv-X after pricing the 2.0L model at RM150K.

I even read in another article (forgot which article) last time that Skyactiv X works even better at lower ron fuel compare to higher ron fuel according to Mazda. Thats why i find the reason Bermaz is giving is contradicting.

Update:
I found the article
