Worn engine oil seals create leaks that are messy, bad for the environment and your wallet. While replacement seals tend to be inexpensive, accessing them tends to involve significant dismantling and high garage labour bills. JLM's Engine Oil Stop Leak additive provides an inexpensive solution.
As they age, oil seals lose their flexibility, which affects their sealing properties. This process worsens on engines that have suffered from neglected oil changes, or endured low-quality (or incorrect specification) lubricant that contained insufficient oil seal preservative additives. JLM's Engine Oil Stop Leak contains the latest in seal-swell additive technology that helps restore their pliability, which also compensates for a degree of wear on the seal lip surface.
JLM Lubricants' Engine Oil Stop Leak also supports the lubrication system of an older engine, by enhancing oil viscosity slightly. Additional benefits include the potential to improve both oil pressure and cylinder compressions, along with the possibility to reduce the quantity of lubricant burnt within the combustion chambers, thus reducing oil consumption further. For cars that suffer from excessive oil consumption but exhibit no external leaks, JLM's Stop Smoke offers a more targeted solution.
For these reasons, JLM's Engine Oil Stop Leak is beneficial for older, higher mileage engines. It does not offer a solution for oil seals that have collapsed, or have suffered from mechanical damage, such as a puncture.
