Massachusetts Oil Burner License Practice Test

Which type of fuel will typically have a lower pour point when blended with #2 oil?

1. Gasoline

2. Kerosene

3. Diesel

4. Jet fuel

The correct answer is: Kerosene

Kerosene is known for its ability to lower the pour point when blended with #2 oil. The pour point is the lowest temperature at which a liquid will flow; thus, a lower pour point is desirable in colder conditions to prevent fuel from becoming thick or solidified. When kerosene is mixed with #2 heating oil, it enhances the fluidity of the blend, making it suitable for use in colder climates. This characteristic of kerosene is particularly valuable in preventing operational issues in heating systems during winter months, as the blended fuel remains easier to pump and burn. Other fuels like gasoline generally do not have the same properties related to the pour point in this context, as they may not provide the necessary benefits when mixed with heating oil. Diesel and jet fuel, while similar to kerosene in some physical properties, do not specifically offer the same advantages in terms of lowering the pour point when blended with #2 oil. Hence, kerosene stands out as the best option for achieving a lower pour point in this scenario.
