ISSUE:
During extended periods of vehicle storage (60 days or more), gasoline may deteriorate due to oxidation. This may damage rubber components and other polymers in the fuel system. It may also eventually clog small orifices in the fuel charging system.
ACTION:
Add Ford Gas Stabilizer (E8AZ-19C544-A) or an equivalent commercially available fuel stabilizer such as "STA-BIL" to the vehicle's fuel tank whenever the actual or expected storage periods exceed 60 days. The instructions packaged with the product should be closely followed. The vehicle should be operated at an idle speed to circulate the additive throughout the fuel system.
