B15 Biodiesel Saves 387 Million Litres of Diesel Per Year

What Is B15 Biodiesel?

B15 biodiesel is a blended fuel composed of 15% palm oil-based biodiesel (B100) and 85% petroleum diesel, mandated by the Malaysian government for the transport and industrial sectors. The programme is administered by the Malaysian Palm Oil Board (MPOB) under the Ministry of Plantation Industries and Commodities. It aims to reduce reliance on imported fossil diesel, support the domestic palm oil industry, and lower greenhouse gas emissions. For Malaysian users, B15 is compatible with most existing diesel engines without modification, making it a drop-in renewable fuel solution.

B15 biodiesel is a 15% palm oil-based blend that replaces 387 million litres of fossil diesel annually in Malaysia, cutting import costs and emissions.

Key Facts

How Much Diesel Does B15 Save Annually?

The B15 programme is projected to save 387 million litres of diesel per year, equivalent to approximately 10% of Malaysia’s total diesel consumption in the transport sector. This figure was announced by the Ministry of Plantation Industries and Commodities during the programme’s rollout in July 2026.

"The B15 programme is expected to save 387 million litres of diesel annually, reducing the country's diesel import bill by RM1.2 billion."

B15 biodiesel saves 387 million litres of diesel each year, cutting Malaysia’s annual diesel import bill by an estimated RM1.2 billion.

What Are the Environmental Benefits of B15?

B15 reduces lifecycle carbon dioxide emissions by approximately 15–20% compared to pure petroleum diesel, according to lifecycle analysis by the Malaysian Palm Oil Board. The blend also lowers particulate matter and sulphur oxide emissions, contributing to better air quality in urban areas such as Kuala Lumpur and Penang.

Palm oil biodiesel is a renewable resource, and the B15 mandate supports Malaysia’s commitment to the Paris Agreement. The 387 million litres of diesel replaced annually translates to a reduction of roughly 1.1 million tonnes of CO₂ equivalent per year.

B15 biodiesel cuts CO₂ emissions by an estimated 1.1 million tonnes annually compared to conventional diesel.

How Does B15 Affect Vehicle Performance in Malaysia?

B15 is designed to be a drop-in fuel for all modern diesel engines (Euro 4 and above) used in Malaysian vehicles, including lorries, buses, and passenger cars. No engine modifications or fuel system upgrades are required. The blend has a higher cetane number than standard diesel, which can improve combustion efficiency and reduce engine noise.

However, older vehicles (pre-2005) may require fuel filter replacements more frequently during the initial transition due to the solvent effect of biodiesel cleaning out deposits. The MPOB recommends a one-time filter change after the first two tanks of B15. In tropical Malaysian conditions, B15 does not suffer from cold-flow problems that affect biodiesel in temperate climates.

B15 is fully compatible with all modern diesel engines in Malaysia and requires no modifications.

Who Is This For in Malaysia?

B15 biodiesel is primarily targeted at fleet operators, logistics companies, public transport providers, and industrial users who consume large volumes of diesel. For example, bus operators in Klang Valley, trucking fleets on the North-South Expressway, and construction machinery in Johor will benefit directly from lower fuel costs and reduced emissions.

Individual diesel car owners in Malaysia will also use B15 at all retail fuel stations, as the blend is mandated nationwide. There is no price premium for B15 over standard diesel; the government subsidises the blend to keep pump prices competitive. The programme is especially relevant for users in compact urban environments (e.g., KL condos with diesel generators) and for those concerned about air quality in high-traffic areas.

B15 is mandatory for all diesel vehicles in Malaysia, from fleet trucks to private cars, with no additional cost at the pump.

Common Questions

Will B15 damage my car’s engine?

No. B15 is approved for all modern diesel engines (Euro 4 and above) by the Malaysian Palm Oil Board and major vehicle manufacturers. Older engines may need a fuel filter change after the first two tanks.

Is B15 more expensive than regular diesel?

No. The government subsidises the B15 blend to maintain the same pump price as standard diesel. There is no additional cost to consumers or fleet operators.

Can I use B15 in my motorcycle or small generator?

B15 is intended for diesel engines only. Petrol engines and small two-stroke engines should not use B15. For diesel generators, B15 is suitable as long as the engine is designed for diesel fuel.
