Anyone use engine oil (such as Mobil 1)

    exclusively for their AR15?

    I use CLP pretty much exclusively and with good results. I was just wondering if there are folks on here who use (or have used) mobil 1 or something like that instead on their AR15's and what their take is.

  2. Common automobile engine oil is more than satisfactory to use on an AR-15.

    Just compare the friction, pressure and heat of a car's engine to the friction,
    pressure and heat of a semi auto AR-15.

    I sometimes use ordinary 3n1 oil on my ARs.
  4. I use mobil-1 50w on my BCG. So far no problems. I use it on my glocks also.
  5. Yep ! 10W20 works like a charm keep the carbon build up down and easy to wipe off! I'd rather pay $4 a quart verus the $50 for AR lubes. Yes I'm a cheap SOB.:supergrin:
  6. I use castrol TWS motorsport 10w 60, the oil thats used for the BMW M3, M5, M6, being an BMW tech i have pretty much an endless supply to this stuff :upeyes:

    I use Mobil 1 aynthetic wheel bearing grease on all but one of my rifle bolt carriers. Otherwise I also use Royal Purple 5W30. My AR'S run really well on lubed this way and these lubricants burn off much slower.
  8. Anyone see any real advantages of the 20W50 over a 5W30? Does the W50 stay put better? Last longer? etc...
  9. No, but I think I'll give it a try this summer when I'm shooting in some Texas dust storms.

  10. Some yrs ago I was shooting at the Grand American world trapshoot and noticed in the Perazzi buildong that their gunsmiths were using some kind of lube on thier expensive shotguns, I asked what it was, Valvoline 50 wgt oil!! and grease on the hinge pins.
  11. Several years ago, Ken Elmore mentioned in an armorer's class that he runs Mobile 1 as a lube, 10w as I recall. But he found it fine and if Ken finds it fine for his guns, I'd say it's good to go for ARs.

    Does anyone actually think the firearm manufacturers test and develop oil?

    They provide a basic spec to the oil company, have an additive like teflon or something added, ask for several hundred gallons packaged in 2 ounce and 4 ounce bottles. They mark it up 600% or more and sell it to you.

    I use 5w30 that is left over from my vehicle.
  14. I use mobile one 5w-30 in my cars and guns.

    I think most any DI AR-15 can run basically dry unless used for full-auto work. 100 rounds at the range per week isn't going to damage anything. Heck, the carbon (graphite) is a lube. I laugh whenever I see an AR spewing oil back into the shooter's face.
  16. Oh boy!!! Another oil thread!!!!!!!!!!
  17. I don't use engine oil in particular but I do usually use just a household all-pupose oil.


    While I'm no chemist, I have long suspected that there only are several types of lightweight petroleum-based lubricants. Aside from motor oils fortified with detergents and such, I think oil is generally oil.

  19. I do. Use CLP on some stuff, but most firearms especially the ones I shoot a lot, get Mobil 1. Works well and it's a hell of a lot cheaper.
  20. I've found that Slip2000 just feels slicker than other oils. When used on my trigger it makes it feel lighter, and seems to last longer, than other oils. It's also relatively expensive and tends to run all over the place. If I use it on my bolt/carrier I'm constantly wiping my rifle down as it seeps out all the cracks. So now I just put a very tiny drop of Slip2000 on my trigger and use Mobil1 5w30 (which I buy for my car) everywhere else. The Mobil1 is cheap, stays where I put it, and works great.
