What is the best fuel mixture to use in my drip torch?

Gasoline, diesel, and kerosene are the fuels most often used in drip torches. Recommended mixture ratios depend on personal preference and ambient temperatures. A common mixture is 60% diesel or kerosene and 40% gasoline when temperatures exceed 75ºF. When temperatures are below 75ºF, a 50:50 ratio may be used. Exceeding 50% gasoline is not recommended because of increased volatility. Greater diesel/kerosene mixtures may be useful under high fuel moisture conditions.
