That was a great link, pretty much covers everything on auto oils and WD-40 and a great reference for finding GOOD
 lubes.

Thank You

ATF is probably pretty good as its a detergent based oil. But very messy and it seems to get everywhere. I would't use it.

In those environments I want something with a more permanent coating like my all time favorite for my 240's which is a mixture of lsa or lsa-t and a super expensive commercial oil that sent us a package when requested for free. You could easily use motor oil but it will attract dust and dirt. If you're going to put your guns through hell just keep them wet with lube. It works on all things I love!

Yup, I use Silkoline Pro 4 Plus 10-50. Works great on my many AR-15 type rifles.

NP. Later in his blog he notes that he received praise from a lubrication industry professional that it is about the best intro article on lube he had seen on the topic.

Also, the GC blog is pretty good.

I haven't used ATF yet, but I might give it a try, despite the warning about it getting everywhere.

I've been using Mobil 1 for nearly 20 years on my AR's, never had a problem with them not functioning in every possible climate here in the PNW. During high rate of fire sessions, my guns ran where the other guys hung up for one reason or the other.

Many competition shooters who shoot 10's of thousands of rounds a year use Mobile 1.  I use Slide glide on my competition guns but on a carry gun Mobile 1 does the trick or when shooting at below freezing temps. 

Mobile 1 works good.

On my M1 Garand I use Lubrimatic high temp wheel bearing grease.  Those heavy semi-autos need grease that stays put.  Never tried it on anything else.  My guess is that it might cause issues.
