Gun Oil Substitutes

Keep in mind that no matter what lubricant you use, you should use
the minimum amount of lube possible. You want it lubricated and not an oil field.

Synthetic Automotive Oils
Synthetic automotive oils (such as Quaker State High Performance Synthetic) work well as general lubricants and because of their detergent capabilities they will help to remove “crud.” (Synthetic oils handle low temperatures better than regular oils.) Just remember, as with any lubricant, not to over lube things. Valvoline Semi-Synthetic Power Steering Fluid has also been used with great success by many folks as their normal lubricant.

Air Conditioning Refrigerant Oil
Air conditioning refrigerant oil, available at most auto dealers and auto stores, is highly penetrative and makes an excellent lube and a rust preventative. It works at high temperatures and very low ones (won’t freeze even when mixed with Freon) and should be just the ticket for Alaskan use.

Slick Stuff
This very “oily”, (i.e. slick, greasy) lubricant appears to adhere very well to metal, with little or no creep. Thus it does not appear to drain from slides and parts during extended storage. From the formula it appears that it might not be suitable at very low temperatures.

2 parts Dexron II or III automatic transmission fluid
1 Part Mobil-1 Synthetic Oil, 30 weight, or 10W-30
1 Part STP Oil Treatment (the stuff for “old” cars w/ over 30,000 mi.)

Amsoil
Another excellent home brew lube is Amsoil Synthetic ATF with some lanolin added to make it even slicker. A synthetic grease from MS Moly called Arctic Grade 67 also makes a great lube especially for cold weather. It is a totally synthetic moly grease with the consistency of chocolate mousse. It does not run, weep or smell (very important for the SAF (spousal acceptance factor)). It is reported to work fine at -30 degrees.

Slippery Stuff
Try 80 percent Marvel Mystery Oil mixed with 20 percent Slick 50 .
