Advantages and Uses of Bardahl Special Duty Insted O’ Lead Gold
Bardahl Special Duty Insted O’ Lead Gold is a unique dual action formula that combines an effective lead substitute for protection from valve seat recession and octane booster (MMT) to eliminate knocking and pinging. Most classic and antique cars were built with 'soft' valve seats that were protected from wear by the use of leaded fuel. If unleaded fuel is used in these older vehicles it will often lead to excessive valve seat wear and can harm the engine. These vehicles may also experience knocking and pinging, which can lead to critical engine damage and expensive repairs. This Special Duty solution will help ensure that a valuable classic or antique car is protected from the effects of unleaded fuel.
How To Use Bardahl Special Duty Insted O’ Lead Gold
Add one bottle to the tank prior to filling-up with fuel. For optimum protection, it is recommended to use Special Duty Insted O’ Lead Gold with every new tank of fuel. For use in vehicles with non-catalytic engines designed to run on leaded fuel only. Dispose of any used or unused solution in accordance with your local, state and federal regulations.
