This is a serious question, don't laugh

Does anyone use synthetic motor oil to lubricate their gun?

Reason I ask is because on another board I had asked about the quality of the M-PRO 7 line of products and someone had responded that they use the cleaner to clean their gun but used Royal Purple motor oil to lube it.

nope, no need, nothing clp can't lubricate and nothing a little clp and elbow greace can't clean.

yes Others use synthetic oil to lubricate.I haven't yet because I haven't run out of CLP , but will probably do so later. Synthetic oil is a great lubricant. CLP works well but its cleaning properties can be lukewarm at best.

I know a guy who spent weeks working synthetic oil into a Browning pump action shotgun he uses to shoot trap. The slide is now so quick and smooth he can shoot doubles with that shotgun.

I'm sure there are alot of applications for synthetic oil for competition shooting and shooting trap/clays. However, I would strongly advise against using synthetic oil on your field gun because it picks up dirt.

My gun only sees daylight when I go to the range.

Motor oil is actually a better LUBRICANT than CLP.
CLP evaporates over time due to the solvent base.
Use CLP right before you shoot and it's fine.
If you want long-term lubrication so the gun is ready to grab and go, motor oil is better in that role.

I have been using synthetic fishing reel oil and grease, stays put, no odor plus its clear.

Nuff said. I have some Royal Purple and some Mobil1 synthetic so once I run out of Hoppe's #9 Dri-Lube, I'll start using motor oil.

LOL!

You mean when I mentioned about RP in the General Gun discussion area of your post. I have two AR's, one lubricated with CLP and another with RP foillowing instructions by ADCO here:

If I were to give you the two (or the one lubed with RP and anything else not) and you rack that bolt it will be immediately apparent. The difference is night and day, like comparing warm butter to sheet of sand paper. This holds true for every firearms I have ever lubed with RP. It also happens to stay lubed MUCH longer and less dirty compared to CLP. Having used CLP almost exclusively for the past decade ever since I was introduced to it during Basic Training I have jumped to RP exclusively now.

The proof is in the performance. Lets ignore the whole "MILLIONS OF DOLLARS" in synthetic oil research and 18,000 RPM runs in racing engine and it's ability to survive an explosion in a chamber compressed 15 ATM. Some will argue that their firearms somehow sees more stress than an engine or how much the "gun companies" put into R&D of gun lube.

I have used Mercon ATF. A little thinner than most motor oils, has great cleaning properties, and makes things nice and slick. Motor oil works just as well though. Personal preference.

CLP on thear's' and mobil 1 synthetic 15W-50 on the others

I can't stand the smell of transmission fluid. Gives me heartburn

[glockman19]

I have heard many guys use Mobil1 synthetic oil and swear by it.

Gun oil for guns and car oil for cars.

Be careful with motor-oils. Some petroleum detergents will remove bluing. They are meant to remove oxidation/black oxide (bluing)/red oxide (rust). I have seen several used guns where they were mostly perfect but 50% or more of the bluing was gone - the story was always the same: "Yeah, the guy cleaned/stored it in motor oil".

Use a good lubricant meant for firearms (I use Breakfree to clean and Tetra brand lubricants to lube). Put motor oil in your car's engine where it belongs.
