One recommendation is to test the fuel sample to tests like Distillation, Existent Gum & RVP. Due to aging, the fuel olefin hydrocarbons get polymerised to Gum, loosing few important properties. An offensive smell is also indication of very old gasoline. Gasoline stored in fuel tanks, vehicle tanks and other containers will with time slowly oxidized and degrade into a sticky material called technically "Gums". Such gums will separate out from gasoline and stick to fuel lines and engine components resulting into inefficient power output.
