We are back with a new edition of Ask The Experts. This time, Gregory Sze quizzes the Petronas fuel technology expert, Chan Ming-Yau, on the new-to-Malaysia Euro 4M RON 97 fuel.

As you may know, the new-grade Euro 4M petrol is now in Malaysia, with Petronas launching its new Primax 97 with Advanced Energy Formula last week, priced at RM2.45 per litre – same as other Euro 2M RON 97 fuels. It’s now available at more than 500 Petronas stations nationwide.

So what’s the difference? Should you upgrade? And is it worth it? Find out here. He had some good news for Primax 95 users too.
