Malaysia’s move to B15 biodiesel reduced average petroleum diesel consumption by 20,410 tonnes a month between June and August 2026, according to Plantation and Commodities Minister Datuk Seri Noraini Ahmad.
The reduction followed the government’s decision to raise the mandatory biodiesel blend from B10 to B15 from June 1, increasing the proportion of palm oil-based biodiesel used in diesel fuel supplied in the country.
Noraini said the reduction in petroleum diesel consumption had helped lower Malaysia’s dependence on petroleum-based fuel. She was responding in the Dewan Rakyat to a supplementary question on petroleum diesel savings and the impact of reduced diesel imports following the implementation of B15.
B15 increases use of locally produced biodiesel
Malaysia’s biodiesel programme uses locally produced palm oil-based biodiesel as part of the country’s strategy to reduce reliance on petroleum diesel.
Noraini said Malaysia’s position as one of the world’s leading palm oil producers provides an advantage in securing raw material for continued biodiesel use.
The shift from B10 to B15 means a greater proportion of biodiesel is incorporated into the diesel fuel blend. The reported reduction of 20,410 tonnes in monthly petroleum diesel consumption between June and August provides an early indication of the petroleum displacement associated with the higher blend.
The minister also linked the increased biodiesel use to energy security, saying locally produced biodiesel could reduce Malaysia’s exposure to fluctuations in international petroleum diesel prices.
Government links biodiesel to energy security and diesel costs
Noraini said greater use of domestically produced biodiesel could reduce exposure to global petroleum price volatility, particularly during periods of geopolitical tension.
She also said the approach could potentially help the government manage diesel subsidy expenditure more effectively.
The comments highlight two policy objectives behind the B15 programme: reducing dependence on imported or petroleum-based diesel while making greater use of a domestically available feedstock.
However, the source does not provide a specific monetary value for diesel import savings or any quantified reduction in government subsidy expenditure.
Studies support B20 use in newer diesel vehicles
Concerns over vehicle compatibility with higher biodiesel blends were also addressed by the minister.
Noraini said studies and field tests conducted by the Malaysian Palm Oil Board (MPOB), together with the Japan Automobile Manufacturers Association (JAMA), found that biodiesel blends of up to B20 were suitable for diesel vehicles built to post-2020 specifications.
She said MPOB continues to engage with JAMA and the Malaysian Automotive Association (MAA) on biodiesel compatibility.
According to Noraini, studies have shown that both B10 and B20 can be used effectively in diesel engines designed to post-2020 specifications.
Malaysia introduced B20 in Langkawi, Labuan and Sarawak, excluding Bintulu, in 2020. Noraini said no problems had been reported in those areas so far.
Palm oil provides domestic biodiesel feedstock
Malaysia’s large palm oil industry provides the feedstock base for its palm oil-based biodiesel programme.
The use of locally produced biodiesel connects the country’s agricultural commodity sector with its transport-fuel system, allowing part of domestic palm oil production to be channelled into renewable fuel applications.
The higher B15 blend therefore represents not only a change in fuel composition but also an expansion of the role of palm oil-derived biodiesel in Malaysia’s diesel market.
Bioenergy Business Analysis
Malaysia’s B15 programme illustrates how biodiesel blending mandates can simultaneously address fuel demand, agricultural feedstock utilisation and energy-security objectives. The reported 20,410-tonne monthly reduction in petroleum diesel consumption provides a measurable indication of petroleum displacement during the first three months following the move from B10 to B15.
The programme also demonstrates the importance of vehicle compatibility and technical standards when increasing biodiesel blend levels. Malaysia’s experience with B20 in selected regions since 2020, alongside the studies cited by the minister, provides the technical basis presented by the government for broader confidence in higher blends for newer diesel vehicles.
For biodiesel producers and palm oil-sector stakeholders, the continued expansion of blending depends on maintaining suitable feedstock availability and ensuring compatibility across the relevant vehicle fleet. The source establishes the government’s policy direction but does not provide longer-term demand, import-saving or financial projections.
The B15 implementation therefore represents a policy-led increase in domestic biodiesel utilisation, with its reported impact so far measured primarily through lower petroleum diesel consumption.
