Answer / Himanshu Chauhan

Similar to the previous answer, kerosene is a stable petroleum product and does not significantly change its color under normal storage conditions, such as in a plastic container for 8-10 years. It should retain its original blue color. However, minor changes in color might occur due to contamination or oxidation, but these are rare under standard storage conditions.
