Whether kerosene can be used in a diesel engine is contingent on the specific engine model. According to some experts, "kerosene will burn fine in most diesel engines without harming them." However, it is crucial to verify if your owner's manual lists kerosene as an approved fuel or consult with the manufacturer before using it.

Kerosene is produced through a distillation process that results in a pure fuel without additives found in diesel. This characteristic causes kerosene to burn cooler than diesel and lack lubricant additives. As a result, running kerosene may strain the injector pump unless an appropriate lubricant is added. A suggested method involves adding "a quart of Marvel Mystery Oil to every twenty gallons of kerosene."

In colder climates, some diesel owners opt for kerosene during winter due to its resistance to gelling compared to diesel fuel. However, this practice may reduce engine power and gas mileage because "kerosene burns cooler than diesel." The article suggests that while the anti-gelling property of kerosene is beneficial, it does not outweigh the potential loss of power and efficiency.

For those storing their diesel engines outdoors in extreme cold, adding kerosene might prevent gelling. Nonetheless, there are approved diesel additives available that effectively combat gelling at a lower cost per gallon.

The article advises using only recommended fuels and supplements for optimal engine performance. Kerosene should be reserved for emergencies when no other fuel options are available. Additionally, proper storage practices must be observed by keeping kerosene and diesel in correctly-colored cans.
