Five years ago, Petronas was the first petroleum company in Malaysia to upgrade its RON97 Primax petrol to the higher Euro4M standard (the ‘M’ referring to a specification adapted for the Malaysian market). Thereafter, other companies have followed and today, all brands are at the same standard.

Now, the company has improved the formulation of Primax 97 and it becomes Primax 97 with Pro-Race. The new formulation is said to help engines run cleaner with reduced friction as well, meaning they can run more efficiently.

Removing 99.9% of deposits
With the claim of 99.9% of deposits removed from key areas, fuel delivery can be better as there will be less blockages in the injectors and other parts of the fuel delivery system. The spray of fuel can therefore be optimized to maximise combustion.

At the same time, combustion can also be smoother because deposits can create ‘hotspots’ inside the combustion chambers. These cause mini explosions which cause roughness so if they are removed, then the engine will have less of those explosions inside.

Of course, it takes a while for the benefits of the new formulation to be experienced, especially if the engine has a lot of deposits already. They need to be gradually ‘washed’ away, a process that used to require disassembly of the engine after some years. However, once they are removed and if Primax 97 is used regularly, it can also prevent deposit formation again.

Advanced Dual Friction Modifier
The new formulation also has the world’s first Advanced Dual Friction Modifier which cuts down the friction levels between surfaces. This makes response better and as the engine can save energy that was used to overcome the friction, leading to improved fuel economy. Petronas claims that this new dual friction modifier can reduce friction by up to 25%.

There is also a unique fuel and oil interaction formulation to enhance efficiency as fuel and oil tend to have issued when coming in contact with each other. By eliminating this, carbon emissions are also lowered, which is better for the atmosphere.

Technology from F1 involvement
The development of the new petrol was carried out with learnings from Petronas’ involvement in Formula 1, via the world championship-winning Mercedes-AMG team. For many years, fuel development has benefitted from extreme testing in racing conditions with the motorist being the ultimate beneficiary.

The new Primax 97 is available at all Petronas stations nationwide and cost the same as other RON97 petrol which currently is set at RM2.08 a litre until December 25, 2020.
