Valvoline Engine oil stop leak 300ml

Valvoline Engine Oil Stop Leak is an additive package that helps reduce engine oil consumption caused by leaking gaskets and seals. It suits petrol and diesel engines running any of the common engine oils, whatever the brand, and you need no special equipment to use it.

Use it when engine oil consumption or an oil leak through leaking seals has been diagnosed.

How to use

• Add one bottle to the engine oil.
• Let the engine idle for 10 minutes so that the additive mixes with the oil.
• Do not exceed the maximum oil level in the crankcase.
• Check the system for leaks. If the leaks continue after 3 days of use, the seals are probably too badly damaged and have to be replaced.

Technical data

• Recommended for: up to 5 l of engine oil
• Safe dose: up to 10% of the total engine oil volume
• Pack size: 300 ml
