Klean-Heat oil lamp fuel burns with little smoke and travels up lamp wicks quickly and easily. It burns with very little odor compared to kerosene. Four 1 gallon (128 oz) jugs per case. Made primarily for kerosene heaters but works great in oil lamps. Klean-Heats clear fuel is a less-smelly alternative to kerosene. Shelf life is 3 years (unopened) and 6 months (after opened - oxygen depletes strength). Important: Keep away from children. Do not swallow. Avoid skin contact.
