The implementation of the sale of B10 biodiesel (diesel fuel blended with palm oil in a 90:10 ratio) in the country has raised much controversy over its suitability for use in modern diesel engines, specifically those designed to run on low sulphur content diesel like Euro 5.

The sale of B10 diesel was supposed to have begun in June, but this was then delayed until further notice. At a Malaysian Automotive Association (MAA) briefing last week, MAA president Datuk Aishah Ahmad said that no date has yet been set as to when the programme will officially be implemented, because the government was listening to all stakeholders.

Nonetheless, despite the delay, the plan to introduce B10 is now heading towards a resolution, according to Malaysia Automotive Institute CEO Madani Sahari. In a video interview with Bloomberg TV Malaysia, he said that ongoing discussions with stakeholders should hopefully resolve the issue.

In June, the MAA sent a letter to the Ministry of Trade and Industry (MITI), claiming the usage of biodiesel in grades higher than B7 may result in fatty-acid methyl ester (FAME) mixing with the motor oil, causing the oil to thin and possibly leading to sludging in the engine. It stated that the majority of its members were advised by their principals that engine warranties would not be honoured on vehicles that ran a biodiesel blend of more than B7, a point that was again made at last week’s briefing.
