FAQs
Is it a permanent fix?
Stop-leak products are a cost-effective fix for minor seepage from ageing seals and small leaks. Large leaks, cracked parts or failed gaskets still need a mechanical repair.
How much do I add to a 4-cylinder engine?
One bottle suits most 6- and 8-cylinder engines, so use half a bottle for 4-cylinders.
How does it reduce blue smoke?
Polymer technology helps seal piston rings and valve guides to keep oil out of the combustion chamber, reducing blue smoke and oil burning.
