Gotta disagree....oil is messier...cuz it drips all over. Grease is an ez clean up. IMO

I like grease! I just use my finger to spread a very light coating on the contact points on my bolt and on the front bearing surfaces of the carrier. When I clean the bolt I use Eds red, and it all cleans very easily. Then re apply grease. I've never had a malfunction. But I keep my gun clean.
I do occasionaly use a drop of light oil on the extractor hinge pin and the ejector. |

Ive found grease is alot easier to manage when cleaning and applying. Doesnt drip at all really.

OK, so all I'm really getting is "oil runs". Which is one aspect I already knew. However, that's also an advantage (a few drops of oil can be dripped into the bolt port holes. Grease can not.). It seems grease is a great lube, but oil is more friendly "in the field" where minute application can be applied. It would seem that when grease is done... it's done (breakdown time), where oil can simply be reapplied (added w/o cleaning) to keep it running.
Again... other than "oil runs, grease doesn't" which in itself is a pro AND con, what else is better about grease? |

Again... other than "oil runs, grease doesn't" which in itself is a pro AND con, what else is better about grease? That's pretty much it. That's the purpose of grease. To remain where it's placed in any condition. It might be more water repellent as well, and might be able to hold more extreme anti pressure additives. Grease is really just oil with a thickener, the base. In lithium grease it's not the lithium soap base that is the lube, but whatever the lube itself is. A copy and paste from I think, ask.com, Greases and oils both lubricate similar materials, but some applications favor one type over the other. For example, oil is easy to pour, which makes it convenient to use in car engines. Additionally, as the oil gradually undergoes chemical changes while lubricating the engine and collects bits of debris, it must be replaced periodically. This is easier to accomplish with a liquid that can be drained easily, as opposed to a grease, which does not flow well.
By contrast, greases are better suited for applications dealing with sealed containers or components that are hard to access. For example, bearings and gears frequently rely on grease as a lubricant, rather than oil. Unlike oil, greases do not carry heat away from moving parts and are unsuitable for use as a coolant. Additionally, because grease does not transport heat well, it is used in lower-speed applications than oils are. Eventually, most greases turn into a full liquid or a hard deposit. Firearms aren't the only place you'll find this argument... fishing reels, bicycles, plenty of machinery in general. It's kind of funny in a way. http://www.machinerylubrication.com/Read/923/grease-oil |

I've thought that oil was better in DI guns since it can "float away" the carbon/residue, one of the reasons for running them "wet". Grease would trap and hold it.
The general thought/rule is "If it slides, grease it. If it rotates, oil it" but not with AR bolts because of the dirt/carbon etc. I'm sure either works well (as evidenced by people's experience on here), but that was my understanding for using oil rather than grease... |

I am in Houston and can run grease year round.
I use XF-7 applied IAW the instructions. I can’t tell it collects carbon, etc. any worse than CLP. If I am doing a lot of shooting I tend to add a few drops of Slip EWL along the way. I like grease for my purposes, someone else may or may not. SEI recommends XF-7 for their weapons. If you think you may like it, try it. It’s not like it is an irreversible decision. |

Also to me grease wins because oil tends to go where it shouldn't and attract dirt like down in the lower trigger pocket.

OK, I'm going to try white lithium grease for a bit (I use that on external piston rifles) for my DI. I'm thinking that, since it's less "sticky" than some other greases, it may clean up fairly easy.
While I love to lubricity of Mobile 1, I am (like prior poster mentioned) getting tired of it running all over the place (stored barrel up, it WILL run down into the buffer tube instead of staying put on the carrier). I'll give it a go. Thanks for the feedback guys! |

I use both.
Some parts get a light coat of grease: Bolt carrier rails, cam pin and cam cut in the bolt carrier, front face of the hammer, bolt locking lugs, trigger contact points. Most other areas get CLP Breakfree, especially the gas rings on the bolt. |

OP try switching to a more viscous form of CLP to see if that will work for you. Some CLP's are just too runny, I agree but there are a few out there that for the most part stay where you put them and don't burn off too quickly. I can't sell you on grease bro because I have no experience with it. I didn't even use grease in the military but that doesn't mean it isn't/hasn't been used before. I have been shooting this platform for about 20 years and can say that CLP evolution has came a long way from what I can tell giving us a lot to choose from. Good luck and report back your choice/results. I hope this helps.

I notice, among the grease crowd, that some grease the gas rings, while others do not. Can someone clarify as to why, or why not, grease the rings?

I do a little bit of grease swabbed on with a qtip.
As for cleaning it, any solvent breaks it down and a wipe takes care of it. |

I have tried lots of products over the years. Recently, I bought a liquid grease from Wilson Combat.
This stuff is absolutely amazing. It goes on as a liquid, stays exactly where you put it, and is slick as snot. My Slip2000 now sits on the shelf. |

I've started using Mobile 1 synthetic grease on the cam pins of my AR's, so there's that.

Grease stays put, but it also holds crap. I use a little grease inside the pin bores for triggers and hammers, but for regular lubrication, I use Mobil 1, Slip 2000, or sometimes CLP. Oil has the ability to flow away from places that it's picked up foreign material and gunk, and it's easy to add a little oil when something's running a bit slowly - can't really do that with grease, and if you tried, you'd just wind up having it hold more gunk and helping to wear your parts.
Finally, what "the AR crowd" does doesn't interest me in this area. A lot of us are notional, insufficiently cautious and even plain flakey. When it comes to maintaining something in working order, I stick with proven materials and procedures. Like OIL for primary lube in an AR. |

I've found that grease is much easier to clean up. Just wipe it down and reapply. Sometimes I'll give a wipe down with CLP there in the middle for the C part. It tends to suspend the carbon rather than running off and leaving a poorly lubricated part that carbon adheres to. |

Recently started using a little grease in certain areas, but oil is mainly what I use. Which would be Mobil 1 leftovers from oil changes.

i had an interesting experience with using Slip 2000 grease that i use in my AK's.
i tried it in a LWRC 12.5" piston upper that had been cut down from 16". i didnt open the gas port because it was over gassed as a 16" and cycled great a 12" with the same port size. that is until i tried grease, then it failed to cycle fully 100% of the time. when i would switchback to oil and it was fine. i tried this twice with the same results and using fed xm193 ammo as well. |

That's an unreliable gun. It should cycle dry, let alone greased. |

Seal1 to clean and various mix of Mobil1 oil and Mobil1 grease for lube. General rule of thumb. If it slides it's grease, if it rotates it oil with a few exceptions.

Second the earlier recommendation of TW25B, but not as a replacement for oil. I use MC2500 and TW25B, and both have their places.
Something else that hasn't been noted in this thread, grease is a handy way to stick parts together temporarily for assembly! |
