Diesel oil can typically sit for 6 to 12 months before starting to degrade if stored properly in a clean, dark, and dry environment. After this period, diesel can begin to form gum and sediment that harm engine components. Using fuel stabilizers can extend diesel's shelf life up to a year or more. It’s also important to check the fuel’s condition regularly if stored for long periods and use it in a timely manner to prevent issues.
