Kerosene Does Not Last Forever Kerosene goes bad over time. When stored properly, it has up to five years of shelf life. This petroleum-based fuel loses its flammable quality when condensation adds water to the storage container over time or mold and bacteria populations transform it into a sludge-like consistency. How Do You Know When Kerosene Is Bad? You can tell when kerosene has gone bad when it turns yellow or murky, develops a visible mold or sludge, or begins to smell like gasoline or diesel fuel. Do not try to use kerosene that has gone bad.
