LUCAS ENGINE OIL STOP LEAK 946ml
Engine Oil Stop Leak is a unique formulation of Lucas additives and very specific base stock designed to stop seal leaks in engines.
Leaking engines are usually older engines. Lucas Engine Oil Stop Leak is not only a leak stopper but also an excellent additive for worn engines. The user can expect less engine noise, higher oil pressure and less oil consumption as the Lucas additives fill the space between worn parts.
Lucas Engine Oil Stop Leak is also effective at stopping leaks in automatic transmissions, hydrostat transmissions or hydraulic systems. 10% is usually adequate though more can be used in badly worn units.
Directions: 
Use 20% of system capacity (Example: 1 quart Lucas Engine Oil Stop Leak to 4 quarts of motor oil)
