Lucas Oil 10279 Engine Oil Stop Leak Additive

Lucas Oil 10279 Engine Oil Stop Leak is a oil additive made from Lucas additives and base stocks, designed to stop leaks in engines. It is also well suited to worn and older engines, where it helps reduce engine noise and oil consumption while raising oil pressure.

Key Features:

• Unique formulation of Lucas additives and base stocks designed to stop engine leaks
• Contains no harmful solvents
• Can extend engine oil life by 50% or more
• Helps reduce engine noise, lower oil consumption and raise oil pressure as the additives fill the space between worn parts
• Also effective at stopping leaks in automatic transmissions, hydrostat transmissions and hydraulic systems

Usage Notes:

• Use 20% of system capacity in engines. For example, 1 quart of Lucas Engine Oil Stop Leak to 4 quarts of motor oil.
• For transmissions and hydraulic systems, 10% is usually adequate. More can be used in badly worn units.
• In gasoline engines, a puff of white smoke from the tailpipe in the morning is a common sign of worn valve seals letting oil seep past the valves when the engine is off. Allow a few days for the product to correct this. To keep the problem corrected, a quart (or litre) will probably need to be added with each oil change.

A good choice for high-mileage and leaking engines that need quieter running, better oil pressure and less oil use.
