Engine Stop Leak - STP 300 ml

Availability: 98 In Stock

STP® Engine Stop Leak is formulated with a special agent to renew polymer seals and gaskets damaged by the heat of normal engine operation, which can otherwise result in oil leaks and expensive mechanical work.

Engine Stop Leak will also increase the protection offered by the existing engine oil.

Volume: 300 ml


• The entire contents should be added to 4-5 litres of engine oil (approximately 15% treat rate), and leave the engine to run for 15 minutes.

• At the normal oil change interval drain as usual. If any leaks persist beyond 1,000 miles/1,500km, mechanical repairs may be required – consult a trained mechanic.


Engine Stop Leak is suitable for regular/synthetic motor oils and contains no solids to clog filters or inhibit flow. Will not harm oxygen sensors or catalytic convertors.


Suitable for petrol and diesel engines.
