Sub-Product

No. 2 Fuel Oil is made of hydrocarbons with 10 to 20 carbon atoms. N° 2 Fuel Oil and Diesel Fuel are nearly the same, but people use them for different purposes. The distinct names mostly reflect the fuels' separate uses more than a difference in chemical makeup. The U.S. government does not impose a tax on No. 2 Fuel Oil, so it has the same red-dyed look as untaxed Diesel Fuel. No. 2 Fuel Oil is untaxed because U.S. citizens use it for their boilers or furnaces to heat their homes. In the U.S., n° 2 Heating Oil must conform to ASTM standard D396.
