Why lubricate the new oil ring on oil filter?

Lubricating the new oil ring on an oil filter helps ensure a proper seal when the filter is installed, preventing leaks and ensuring optimal engine performance. The lubrication allows the rubber or silicone material of the oil ring to better conform to the engine's surface, reducing the risk of damage during installation. Additionally, it aids in the removal of the filter during future changes, making maintenance easier. Overall, this practice enhances the effectiveness and longevity of the oil filter.
