Gasoline is a type of fuel that is widely used in cars and motorcycles. The Company’s refinery was the first one in Thailand to produce Euro IV standard gasoline, with certain changes in the oil product specifications including a decrease in the amount of sulfur from 500 ppm to a maximum of 50 ppm, which reduces sulfur oxide (SOx), carbon monoxide, and nitrogen oxide emissions. The amount of benzene, which can cause cancer, has also been reduced.
          The company also produces gasoline base (G-Base) which, when combined with 10%, 20%, and 85% of Ethanol, will become gasohol E10, E20, and E85 respectively. Today, the Company produces Gasoline 95, Gasoline 91, Gasoline Base 95, and Gasoline Base 91 primarily for domestic distribution.

          Diesel fuel is used in the diesel engines found in cars, trucks, tractors, passenger boats, fishing boats, trains, and industrial factories. Today, all diesel fuel sold or offered for sale in Thailand must contain 7% biodiesel.

          Thaioil refinery is Thailand’s first producer and distributor of Euro IV standard diesel where the sulfur content is 7 times lower than that in the previous standards. This helps reduce sulfur oxide (SOx), carbon monoxide, and nitrogen oxide emissions, as well as soot and lampblack, into the atmosphere. It further increases the performance of diesel engines.
