The ASTM recognizes two grades of kerosene: 1-K (less than 0.04% sulfur by weight) and 2-K (0.3% sulfur by weight). [16] Grade 1-K kerosene burns cleaner with fewer deposits, fewer toxins, and less frequent maintenance than 2-K, and is the preferred grade for indoor heaters and stoves. [17] In the United Kingdom, two grades of heating oil are ...
In small two-stroke engines, the oil may be pre-mixed with the gasoline or fuel, often in a rich gasoline: oil ratio of 25:1, 40:1 or 50:1, and burned in use along with the gasoline. Larger two-stroke engines used in boats and motorcycles may have a more economical oil injection system rather than oil pre-mixed into the gasoline.
