Singapore To Introduce Limits on Additives in Petrol and Diesel

Singapore, 24 July 2018 – As part of the National Environment Agency (NEA)’s on-going efforts to further improve Singapore’s ambient air quality and safeguard public health, NEA will regulate additional fuel quality parameters and additives in petrol and diesel with effect from 1 July 2019.

2          NEA will introduce limits for methanol, methylcyclopentadienyl manganese tricarbonyl (MMT), phosphorus and fatty acid methyl ester (FAME) additives in petrol and diesel (refer to Annex A for the limits). These additives, if added into petrol and diesel, have negative effects on the environment and public health. Methanol produces toxic substances such as formaldehyde, which is a carcinogen, while manganese and phosphorous damage catalytic converters in petrol vehicles leading to higher emissions over time. FAME may increase the emission of nitrogen oxides (NOx) from diesel vehicles, and NOx increases the risk of respiratory infection in humans and reacts with other compounds to form ozone.

3          NEA regularly reviews and tightens vehicular emission standards, as well as fuel quality standards for automotive use under the Environmental Protection and Management (Vehicular Emission) Regulations. From 1 July 2019, all petrol and diesel retailed at petrol stations and other authorised outlets will have to comply with the new limits.


Limits on Additives in Petrol and Diesel (with effect from 1 July 2019)



*Manganese requirements shall follow Clause 5.3.3 of EN228:2012



*Manganese requirements shall follow Clause 5.3.3 of EN228:2012

Note: The limits above are benchmarked against the EN228 (petrol) and EN590 (diesel) standards.
