AR lube Grease or ATF

Since I work at an airport, jet engine oil is cheap and plentiful ($15 a quart for 2380), runs quite well into all the nooks and crannies, designed for high temperature use...

Basically, it comes down to whatever works for you.

I use Lubriplate Engine Assembly grease ('cause I had it anyway) when I reassemble and lube with Breakfree LP when shooting.

Ballistol is a light mineral oil, it well work but on the light side. Any of the fire arm oil products well work, everyone has their favorite. I like Militec on my AR's, NO grease. Engine oils work but migrate during storage to the lowest point.

Not sure where the reference for this is:

Carcinogens

I'm reluctant to use engine oil. I dont know how much of it burns off when used in a rifle but it has shown to be carcinogenic so inhaling it may not be the best idea.
I'm not saying "gun" oils arent carcinogenic but i do know for certain that engine oil is.
Whatever you use rubber gloves should be worn during application.

Proof of rust resistance, but not lubrication.

If you are concerned about any material, check the Material Safety Data Sheet (MSDS). MSDS's are easily found on the web.

I do not recommend inhaling any oils! Used oils will have heavy metals from the engines. For new motor oils, don't worry about it:

CHRONIC/OTHER EFFECTS
For the product itself:
Diesel engine oils: Not carcinogenic in animals tests. Used and unused diesel engine oils did not produce any carcinogenic effects in chronic mouse skin painting studies.
Oils that are used in gasoline engines may become hazardous and display the following properties: Carcinogenic in animal tests. Caused mutations in vitro. Possible allergen and photoallergen. Contains polycyclic aromatic compounds (PAC) from combustion products of gasoline and/or thermal degradation products.

Contains:
Base oil severely refined: Not carcinogenic in animal studies. Representative material passes IP-346, Modified Ames test, and/or other screening tests. Dermal and inhalation studies showed minimal effects; lung non-specific infiltration of immune cells, oil deposition and minimal granuloma formation. Not sensitizing in test animals.

IMMEDIATE HEALTH EFFECTS
Eye: Not expected to cause prolonged or significant eye irritation.
Skin: Contact with the skin is not expected to cause prolonged or significant irritation. Contact with the skin is not expected to cause an allergic skin response. Not expected to be harmful to internal organs if absorbed through the skin.
Ingestion: Not expected to be harmful if swallowed.
Inhalation: Not expected to be harmful if inhaled. Contains a petroleum-based mineral oil. May cause respiratory irritation or other pulmonary effects following prolonged or repeated inhalation of oil mist at airborne levels above the recommended mineral oil mist exposure limit. Symptoms of respiratory irritation may include coughing and difficulty breathing.

ADDITIONAL TOXICOLOGY INFORMATION:
This product contains petroleum base oils which may be refined by various processes including severe solvent extraction, severe hydrocracking, or severe hydrotreating. None of the oils requires a cancer warning under the OSHA Hazard Communication Standard (29 CFR 1910.1200). These oils have not been listed in the National Toxicology Program (NTP) Annual Report nor have they been classified by the International Agency for Research on Cancer (IARC) as; carcinogenic to humans (Group 1), probably carcinogenic to humans (Group 2A), or possibly carcinogenic to humans (Group 2B). These oils have not been classified by the American Conference of Governmental Industrial Hygienists (ACGIH) as: confirmed human carcinogen (A1), suspected human carcinogen (A2), or confirmed animal carcinogen
with unknown relevance to humans (A3).

Slip 2000 EWL did better in that corrosion test than that Mobil 1 did. Slip is also a great lubricant and, in my opinion, an overall superior product for use in extreme environments (hence the name).

If I ever had to take my AR into extreme environments, or found that I was experiencing corrosion or lack of lubrication performance issues in my guns I'd switch from my $ 6.00 a quart M1 V twin 20-50 to the $ 60.00 a quart Slip 2000 EWL. http://www.midwayusa.com/viewproduct/default.aspx?productnumber=311938

When I go to Alaska in the Winter or Afghanistan in the Summer I'll grab the EWL. For now, in South East PA, the M-1 is working fine.

There are studies linking additives and chemicals used in refinement of motor oil to cancer. I do not know if it is a significant risk or how much are present in different brands.
I did notce that the MSDS does indicate that carcinogens are created from combustion of oils as would occur if used inside a gun, ecspecially a DI gun. However, this is likely to be the case with any oil based lubricant so gloves should be used for cleaning regardless.

EESOX user here been very satisfied with it since 2000... I also do use a bit a grease (miltec1)

Mobil 1 10-40

I use KY Jelly. Water based when shooting corrosive ammo.

Yes, I am kidding.
