Methanol Blends

The Danish Executive Order on the quality of petrol, diesel oil and gas oil for use in motor vehicles allows up to 3% v/v of methanol in conventional gasoline.

In 2020, the Danish Technological Institute and the Danish Methanol Association organized trials of gasoline blended with up to 85% v/v of methanol. The RON number of this blend is 105. This so-called 105 Octane M85 is manufactured according to ASTM D5797 – 18 Standard Specification for Methanol Fuel Blends (M51–M85) for Methanol-Capable Automotive Spark-Ignition Engines. This specification covers the requirements for automotive fuel blends of methanol and gasoline for use in ground vehicles equipped with methanol-capable flexible-fuel, and dedicated methanol spark-ignition engines.
