Which drip torch mixture statement is correct?

• A. 3:1 diesel:gas
• B. 1:3 diesel:gas
• C. 2:1 diesel:gas
• D. 4:1 diesel:gas

Answer: (A)

The key idea is balancing burn rate and safety when using a drip torch. Diesel serves as the main fuel because it burns steadily and isn’t highly volatile, while gasoline acts as a thinner to help the torch ignite and establish flame, but it increases volatility. The preferred mix is three parts diesel to one part gasoline. This ratio provides a reliable, controllable flame that lights predictably and spreads at an appropriate rate for prescribed burning. Using more gasoline would make the burn too volatile and harder to control, while using less gasoline (more diesel) would slow ignition and burn. So, three parts diesel to one part gasoline is the best balance for a controllable, safer burn.
