Motul Engine Oil Stop Leak is a quick-acting additive designed to address minor oil leaks without the need for engine disassembly. It’s formulated to make small leaks stop by conditioning and restoring elasticity to rubber seals and gaskets, allowing them to seal tight where they may have been failing slightly due to age, heat, or shrinkage. It is a temporary / preventative solution rather than a permanent fix for major leaks, but highly useful for reducing oil loss, improving reliability, and helping avoid frequent top-ups. Because it's compatible with any engine oil type, it can be used easily during regular oil changes or added to existing oil when a leak appears. Users should monitor oil levels after use and apply as per instructions for safe dosing.
