K-1 Versus K-2 Kerosene

Q: What is the difference between K-1 and K-2 kerosene? Also, why is the fuel can blue?

A: The main difference is the sulfur content. K-1 is very pure kerosene with low sulfur content and is most commonly used. K-2 can have as much as 10 times more sulfur. The fewer the impurities in the fuel, the cleaner it will burn. K-1 is intended for use in space heaters and lamps. K-2 is intended to be burned in heaters that have an external flue to remove the exhaust from the room. Lastly, the color of fuel cans is used to quickly identify what type of liquid is being stored without needing to read a label. Red is for gasoline, yellow is for diesel and blue is for kerosene.
