The Lucas Extreme gun oil is the same as the Lucas Semi-synthetic 2 stroke racing oil. I know there's a automotive oil that's the same as the standard Lucas gun oil too. But for the life of me I can't remember what it is

There are a few purple gun oils and greases out there also for $$$, and they're just re-packaged auto lubricants. Can you guess the name brand?, yep Royal Purple.
 
Does anyone know the sulphur content of their gun oil ?
I was using ATF for years until I learned of the sulphur content.
I've been using jojoba oil lately.
 
The primary additive in the Lucas Extreme Gun Oil is Zinc Alkyldithiophosphate; looks about 15% per the MSDS. It is a multipurpose additive that is particularly suited for a rust and corrosion inhibitor as well as an effective anti-wear agent. The Zinc Alkyldithiophosphate forms a film and acts as a physical/chemical barrier to water reaching metal surfaces as well a metal to metal contact on sliding surfaces.

I use the Lucas Extreme Gun Oil and Gun grease, it seems to do a great job preventing rust and corrosion and minimizing friction and wear. I'm sure there are other brands that are just as effective. Motor oil will work fine as well, it just has other additives (VI improvers, pour point depressants, anti-foam, detergents, dispersants, etc.) that aren't really necessary for our firearms.

Bottom line: keep your firearms clean and use a lubricant that you have confidence in.

As a layperson (non-professional), I would “guess” that following the maintenance schedule and lub recommendations for any modern vehicle would more that suffice for longevity. In turn, when you count the number of rounds it would take to wear out a firearm action that has appropriate care, I would again guess that most gun oils will do the trick.
Most people do not realize how powerful advertising and peer pressure can influence their decision-making process. I am sure that Lucas products will do the trick for both vehicles and guns if that is what your brain tells you.
 
I've been using the "original" red colored Lucas Gun Oil for several years. Bought some at Rural King on a whim and found it had just about the perfect viscosity for staying where I put it but still lubricating well.

Next time I buy, I'm probably going to try out the Extreme Duty both due to the good things I've read about it and I like the needle-bottle for getting it precisely where I want it.

This is correct. Zinc is a “heat seeker” used in compressor and transmission oils as well as hydraulic and engine applications. When there are spots that rub and create heat the zinc plates out to make a smoother surface

I sell industrial lubricants for a living. I can assure you that there is a tremendous difference in the performance of typical low end versus higher quality products

But, you always have the chimps that think every product is the same no matter brand or price

Lucas Marine Grease... will stay exactly where you put it, does not evaporate, does not liquify and get all over your clothes or the grip of your gun. I put it in a syringe and use it on most everything, rails, semiautomatic pistol rub points, barrels, etc... it only takes a touch. But I reserve it for warmer weather. It slows things down if it's really cold out. Mobil 1 0-20W for everything else. A quart will absolutely last for ever for gun lube purposes.

I often put a drop of Mobile 1 on rails already greased with LMG. It seems to work extremely well and stay in place when applied to the grease.
 
I run a gallon a year, ( ounces at a fill up) of Lucas Fuel System and Injector Cleaner in my Silverado. takes about 3 months to use up a gallon. I'll try their gun oil. hdbiker

The base stock in the Lucas products appears to be a highly refined mineral oil; chances are the sulfur content is measured in Parts per Million. We would need to see the material analysis to know the range that may be present. I'd say its a very low PPM number and would not have any concern about use with our firearms.

Some ATF may contain a sulfur/phosphorus extreme pressure additive. There are sulfur/phosphorus EP additives that can be reactive with brass and bronze metallurgy which could cause issues in transmissions and gearboxes that contain "yellow" metals.
 
NEVER, in a million years, would it have dawned on me to do this! Another one of those so obvious things that I’m wondering why it never occurred to me before.

Yup. It's not ideal of course but when some newb (or CHL student) shows up with a dry weapon it'll get/keep things running. :thumbup:

What's the source for this info? Can you post a link?

Edit: The SDS's of the two show different viscosities, densities, boiling points, flash points, ingredients, etc. They don't appear to be the same thing at all.

I also found it to be pricey ------ now I use liquid wrench chain and cable Lub----been using it for 3 years and very happy with it.
 
Here's a good article that will dispel some of the myths about high end gun lubricants being that much different than your typical automotive lubes.

https://www.realgunreviews.com/whats-really-in-gun-cleaners-lube/
From the article, and something I have said here numerous times.
"That you clean and lubricate your guns regularly is far more important than what you clean and lubricate with."

Keeping it clean and lubricated is far more important than which lube.
 
Combines with water to make sulfuric acid

Nope. Sulphur doesn't react with water. Sulfuric acid is H2SO4. You need the sulphur and two additional hydrogen ions.

You can mix elemental sulphur with water all day long and all you'll get is wet sulphur.
 
Got some with my XDE when I bought it. Haven't tried it but I use 5-20 motor oil with a little trans oil mixed in. Works just fine.

Not bragging just fact, did that a few months ago to get my neighbors mail key to work in the cold.
 
I added some of the Lucas extreme duty gun oil to an order a few months ago to bump it up to the free shipping level. I've been using it on an AR bolt and it's been working fine, it is more viscous than my usual 5W-20 or Slip 2k, and seems to stay a little better, so that's good. I took that AR out a month or so ago when it was -2 deg and put a bunch of rounds though it, the oil did did not thicken up to any noticeable extent and the gun ran like a top.
 
I've been using Weapon Shield products for the past few years and have been very happy with them. That said, I loathe the WS oil bottle. It leaks horribly (I have to keep it in a Ziploc bag) and you can't put a small drop anywhere. Looks like it might be time for me to try out some Lucas oil.
