Can kerosene be used instead of diesel?

Kerosene can be used as a substitute for diesel in some applications, particularly in older diesel engines designed to handle a wider range of fuels. However, it has a lower lubricating quality and energy content than diesel, which can lead to increased engine wear and reduced efficiency. Additionally, using kerosene in modern diesel engines can cause damage and void warranties. Always consult the manufacturer's guidelines before making any fuel substitutions.
