What is the recommended fuel mixture for a drip torch?

The recommended fuel mixture for a drip torch is two parts gas to one part diesel. This particular ratio allows for optimal performance in fire ignition while ensuring the fuel remains stable and manageable. Gasoline has a lower flash point and ignites more easily, making it effective for creating a quick flame. Diesel, being less volatile, provides a sustained burn that enhances the effectiveness of the ignition.

By using two parts of gas, the mixture becomes more flammable and assists in easily spreading fire, which is vital for controlled burns and fireline preparations. The inclusion of a proportion of diesel helps to maintain burning for a longer duration without the volatility that pure gasoline would present, thus allowing for safer handling and application by firefighters in the field.
