    I have seen this mentioned a couple times but it's real rare... Just curious who here actually uses 40W motor oil or whatever other W motor oil you prefer? Does it work the same as the hoppes or other lubricants?

    Does anybody add the Loctite copper C5-A lubricant to their guns? I noticed Glock uses it as a break in lubricant on the rails of the slide... Does anybody add more to it once it's gone or add it if the guns will sit for a long time?

    Also who has used the Weapon Shield brand lubrication oil on their guns and how well does it work?

  3. I use Mobil 1 in whichever bottle I have on hand and white lithium grease for when I want it to stay in place. Don't see a problem with them, my engines see much harsher environments than my guns ever will

  4. I like Mobil 1 too. A quart will last a long long time.

  5. SLIP 2000 for parts that need oil, white lithium grease for slide rails and the internals of my H&K P7. I only use motor oil in my car's engine.

    I often use light weight synthetic motor oil in my guns and notice significantly smoother operation than with almost any gun oil I've used. Only problem is the smell.

    YMMV, but I think gun oil is sold at an unbelievable markup. Synthetic motor oil is designed to lubricate at a very broad range of temperatures for many, many cycles, and to hold fouling and debris in suspension. Seems more than adequate for use in guns.
  7. Mobil 1 synthetic wheel bearing grease.
  8. Mobil 1 5W10 in a needle oiler for internal lube. Slide glide lite or TW25b for frame/slide rails and barrel/slide contact areas.
  9. Militec-1.. Can be used in engines as well.
  10. I recently started using a mix of 2 parts of Mobil 1 Synthetic 20w50 to 1 part Mobil 1 Synthetic Transmission fluid. One of my old LEO friends turned me onto this mix. His department uses this on their patrol rifles, as does the firearms guys at the Indiana Law Enforcement Academy. Stays put and does not burn off easily. This is supposedly close to the same mix that Navy Seals use on their weapons.

    I've used nothing but Weapon Shield for a couple of years now on all of my guns for both lube and cleaning. I'm sold on it.
  12. I use a bit of 'Royal Purple' very light weight synthetic oil at times. I think it's 0-20w, or 5-20w. I've mostly used it for higher volume AR shooting, like in a SD dogtown where the shot count can go into the 100's. I didn't want my AR to go dry.
  13. Mobile 1 5w20.

    Read on line several years ago a military spec for gun lubricant and Mobile 1 beat it in every category.

  14. I use Royal Purple on my AR's and Gun grease on the rails of my 1911's. I have noticed that the action on my weapons is significantly smoother and the oil does not burn off nearly as fast.
  15. I had used Castrol GTX 10w-30 for a period of time. Nothing went wrong at that time. but now I use Rem oil to clean and Frog Lube for the action. I just enjoy the smothness frog lube gives me and not to worry about breath in half oz of motor oil every time I go to indoor range.

    Whatever Synthetic oil is around...Royal Purple, Mobil1......weight doesn't matter.
  17. I use Mobil one V twin 20/50 in my Harley I have at times drained what ever is left in a bottle into a smaller bottle and used it on my pistols and rifles with great results. Figure if it good enough for a 14,000 dollar Harley it's good enough for a 500 dollar glock that doesn't take much lube to make it work.

    5W-30 whatever is left in the bottom of my quart bottle I put in to a cheap squeeze bottle from Wally for travel shampoo. They are cheap and work great. You dont need a lot especially on a Glock.

    Works great.
