The Coleman 508A stove is designed to use unleaded gasoline only. Diesel fuel is a heavier fuel that will not burn properly in the stove and can damage it.
Diesel fuel also has a higher flash point than gasoline, meaning it is more likely to catch fire. This is a dangerous characteristic for a camping stove, as it could easily start a fire if it is spilled or if the stove is not used properly.
In addition, diesel fuel produces more soot than gasoline, which can clog the stove's burner and reduce its efficiency.
If you are looking for a fuel that is safer and more efficient for use in your Coleman 508A stove, stick with unleaded gasoline.
