Lucas Engine Oil Stop Leak Additive 946ml – 40278

Lucas Engine Oil Stop Leak is a specially formulated additive designed to stop seal leaks in engines, using a unique blend of Lucas additives and base stock. Safe for all engines, it can extend engine oil life by at least 50%.

For Petrol Engines: If you notice white smoke from the exhaust in the morning, it’s often due to worn valve seals allowing oil to seep past the valves. This common issue in high-mileage engines can be corrected with a few days of use of Lucas Engine Oil Stop Leak. For ongoing prevention, it’s recommended to add 946ml with each oil change.

For Older Engines: Lucas Engine Oil Stop Leak is particularly effective in older engines. It helps reduce engine noise, increases oil pressure, and lowers oil consumption by filling gaps between worn parts with its powerful additives.

For Transmissions and Hydraulic Systems: Lucas Engine Oil Stop Leak also works well in automatic transmissions, hydrostatic transmissions, and hydraulic systems. Use about 10% of the product, or more for severely worn systems.

Directions: For cars, replace one litre of engine oil with one litre of Lucas Engine Oil Stop Leak. For larger engines (e.g., diesel), use 10-20% of the product.
