    AeroShell Fluid 18 Mineral Lubricating Oil offers superior corrosion protection wherever water may come in contact with metal parts. It can be used for a variety of applications including aviation, automotive, industry and more. The fluid lubricates while it protects and can be used indoors or out. The highly refined petroleum-based lubricating oil works well at moderately low temperatures, but is not recommended for use as a lubricant in extremely low temperatures below -57 degrees C. AeroShell Fluid is sold in a 1-gallon can. For more information about the chemical composition or for use instructions, please see the MSDS linked above.


    AeroShell Fluid 18 is for use in the lubrication and corrosion protection of small arms and automatic weapons and as a general purpose lubricant for all applications where water displacing, corrosion protection, and low temperature lubrication is required.

    AeroShell Fluid 18 is also intended for locks, hinges, electric motors, fans, small bearings, control rods and cables and can be used in numerous non-aviation applications.

    AeroShell Fluid 18 is not recommended as a lubricant at temperatures below -57°C.

    I've been using this for about 2 years and it's my favorite gun lube.
    I live in Oregon and shoot both in the summer and in the winter, rain or shine. I have had zero problems with rust after switching to AS 18, which is even more impressive as I frequently shoot corrosive ammo. It's a pretty thin oil but works well on every weapon I've tried it out on. Not rated as a cleaner but AS 18 actually does a decent job of carbon removal too. All this for less than 1/2 the price of CLP.
    ProsPrice Effectiveness Low odor
    ConsDries after months in storage
