Description

Quicksilver 858081KC3 is a genuine OEM Storage Seal engine fogging oil / rust inhibitor in a 12 oz spray can. It is designed for winterization and long-term storage, forming a protective barrier on internal metal surfaces while helping keep cylinders lubricated during lay-up. Mercury and Quicksilver product references describe it for 2-stroke and 4-stroke gasoline engines, including carbureted, fuel-injected, and catalyzed applications.

Engine Compatibility
This product is intended for gasoline engines rather than a single engine family. Mercury and Quicksilver describe it for use on outboards, sterndrives, and other internal-combustion gasoline engines where fogging oil is recommended during storage. Match use to the engine owner’s manual and lay-up procedure.

Serial Number Fitment Notice
Confirm the correct storage and winterization product by engine model and serial number before ordering, especially when following a manufacturer-specific lay-up procedure. Mercury’s parts catalog is the best place to verify the correct service items for a specific engine.

When This Part Needs Replacement
Use during winterization, seasonal lay-up, or any extended storage period when internal engine corrosion protection is needed. It is meant for storage prep, not as a routine running lubricant.

Installation Notes
Follow the engine owner’s manual for fogging procedure. Quicksilver describes this as a heavy, sticky spray lubricant intended to coat internal engine surfaces, and Mercury references its use through the air intake and cylinder protection process during storage prep.
