So yes, it would appear to be 15% ZDDP, which is WELL past the corrosive level of >1500ppm.


Perhaps that's what Lucas meant by "Extreme". Extremely corrosive.

I have not found it to be corrosive either in use, or in "static" testing with saline solution of water on bare steel.

ZDDP hydrolyzes into hydrogen sulfide and sulfuric acid. Because water is always a risk in steam turbines, this is a concern.

3. While much less so than EP oil, ZDDP-based anti-wear oil can corrode babbitted surfaces.

4. ZDDP also might interfere with rust and corrosion inhibition.


Tanks god that modern ACEA oils have high TBN levels

That's DEER LUBE..........

But do we know the TBN on the Lucas?

I am 102% that it meets & exceeds multiple MIL-something standards

This is why I don't use it, and why I don't use engine motor oils. That said, I have not personally had a corrosion issue with it when I was testing it.

According to Lubrizol ZDDP protects metal from corrosion

I would have to agree with that. Zinc has proven in the galvanizing industry to PREVENT corrosion, not cause it. Bridges and outboard motors use sacrificial Zinc anodes to stop corrosion of metal through galvanic action as well.

The label

I'll accept that as gospel Tom.

In the interest of full disclosure. I recently bought a 2 1/4 oz. bottle of Hoppe's Lubricating Oil.

Why? I liked the color of the bottle..lol. I doubt its as good as a mixture of ATF/Gear Oil..but I am using it anyway. Can't totally explain why.

It requires excessive amounts before it becomes corrosive.

I was bored yesterday after Good Friday church services at Noon - had the necessary liquids and took the plunge.
Here's what I used to make my homemade CL.... not sure about the "P".

2-1/2 (whiskey) shots of synthetic Pennzoil Platinum 5w30
1-1/2 shots of ATF Fluid
1-1/2 shots of STP Oil Treatment (blue)
1 shot of Marvel Mystery Oil
3/4 shot of Hoppes #9 solvent

Sure is slippery and sure does smell. Hoping to try it out in a couple more weeks. I'll be sure the home is vacant of wife and grandkids when I clean/oil the pistols. May be a good time to do an incense smudging with the Abalone Shell and turkey feather afterwards.

I have enough store-brand gun oils for the next 6-7 years. Why I did this -- I haven't a clue. We all seem to do some experimenting and I guess it was my turn. I have not touched that whiskey shot glass in many-many years. I'm surprised it was still on a shelf in the laundry room, along with 11-12 different booze bottles with an inch of dust on the bottles.

Why do I understand your logic perfectly.

I think though adding the STP and MMO (Kerosene) didn't add anything instead of bulk. I basically juggled the ATF and gear lube to get the right (thin) viscosity. But ultimately I doubt my simple blend of ATF abd Gear lube performs any better (or worse) than yours...lol.

I wonder what lube John Browning used?

 

[Astro14]

John Browning would have drank the whiskey, using the shot glass for its intended purpose.

Then, he would've used whatever oil was handy and not obsessed about it...

I think he would have been shocked that the whiskey bottles were dusty, and the oil bottles were the subject of all the discussion....

I'm kind of shocked by that, too...

 

[alarmguy]

I see 11 pages of responses, Im reading none )
Gear oil can be corrosive to any soft metal and rubber, whether that will harm the finish I dont know. ATF WILL possibly ruin the finish. Plain old motor oil would be a better safe choice.

If you would have read the 11 pages you would yealize that your statements are almost certainly incorrect.

I have used it to lubricate 3 revolvers, 2 1911's, a S&W Sigma, 2 Ruger autos (Polymer), Glock (Polymer), S&W Shield (Polymer). No problems so far. I am 70 and I doubt I will see any problems in my lifetime..lol.

Post of the Week.... maybe the Month.

The youngest of those booze bottles is probably 30 years old. The wife and I have never drank hard booze. It was there whenever company arrived.

Nowadays, company either never shows up or the company we once entertained, are now either moved, befriended us or dead.

Actually, that stuff is plain ol' pharmacy grade mineral oil. Enjoy!

 

[Triple_Se7en]

I don't use it anymore, but Hoppes oil has more than just mineral oil in it.

I just bought a Hoppes cleaning brush kit a few weeks ago, with a 2oz or-so bottle of Hoppes oil in it.

I dumped it inside a five quart jug of various leftover motor oils. My 99' beater S-10 will use it eventually, for it holds almost five quarts.

That S-10 will also likely see my failed concoction of gun lube involving Motor Oil, ATF, Marvel Mystery Oil and STP treatment. That stuff smells horrid and will never-ever put motor oil in my guns. That's another 4-5 ounces headed inside my S-10.

It's unfortunate that the smell is so bad. For the lube is very slick / slippery.
