Long term Mobil-1 immersion effect on bluing?

Canning uses high temperatures to kill off the microorganisms. http://en.wikipedia.org/wiki/Canning

That's not why fruit is often completely immersed in syrup, though. You don't need immersion to kill germs, but immersion helps preserve the food from oxidation both before and after opening. It also helps that the heat from processing helps deactivate the naturally occurring polyphenol oxidases in the fruit as well.

Microorganisms don't do this, oxygen does:



That's also why things that are packaged for a really long shelf life usually contain some sort of oxygen absorber. It's usually oxidation and other chemical processes, not microbial growth, that limits the shelf life of canned foods, assuming it was canned properly (and hence sterile) to start with.


To the question of whether or not PAO based synthetic motor oils have corrosion inhibitors:

Additives enhance the performance of motor oil basestocks and help adjust the performance of the oil to suit its intended application. Additives are the key to unlock the performance potential of basestocks but even the best additives won’t turn bad oil into good oil.

Some common additives include:
• Viscosity Index Improvers – improve ability to handle heat and severe conditions
• Pour Point Depressants – lower oil freezing point in cold conditions
• Anti-wear Additives – protect against metal-to-metal contact
• Detergents & Dispersants – keep components clean and prevent sludging
• Oxidation Inhibitors – maintain oil stability over service intervals
• Corrosion & Rust Inhibitors – protect against the effects of condensation
• Defoamants – prevent oil foaming and cavitation

Additives work symbiotically with the base stock and are added in different proportions according to the application. Some examples are that racing oils may not require rust inhibitors but could need extra defoamants for dry sump oil systems, domestic or consumer engine oils may need special additives that don’t interfere with the operation of catalytic converters or diesel oils may require additional protection against combustion byproducts.

Full race oils may not have corrosion inhibitors in the additive pack, but synthetic oils made for street cars certainly do.

And why I prefer synthetic PAO-based synthetic lubricants over oils refined from cooked sea algae and dinosaur carcasses marinated in salt and sulfur...

Conventional motor oils use base stocks created by the conventional refining of crude oil pumped from the ground. Crude oil is a complex mix of hydrocarbon compounds and a variety of sophisticated refining techniques are used to remove/reduce the amount of undesirable components such as asphalts, waxes and chemically unstable sulphur & nitrogen compounds. Conventional motor oils use conventional mineral base stocks so are usually known as Mineral oils.

Mineral base oils have performance limitations. After refining what remains is a lubricating base stock that despite the degree of chemical refinement still contains undesirable materials such as oxygen, sulphur, nitrogen compounds, trace metals and carbon residues.

There are literally thousands of compounds present in crude oil. While many of them are removed or upgraded by refining, a significant concentration of these undesirable materials remains in lubricating oil base stocks. These residual undesirable materials mean additive packs can’t operate to full effect because the additive has to compete for space with the impurities when they attempt to bond with the baseoil molecules. Consequently the molecular structure of the oil is inconsistent, limiting the performance capabilities and useful service life of the resulting blended oil.

Judging the tangent this thread is taking...I think it's a Monty Python.

There are almost as many oils and motor oil standards as there are lawyers. As one would imagine, none of the motor oil standards address firearms. In answer to the OP's question, IMO immersing guns in motor oil for extended periods will have no deleterious affect. (Standard disclaimer goes here............)

Just keep in mind that the 50 weight makes your firearm heavier than 10 weight.

For those interested in the use of synthetic motor oil as a "gun oil", here is a source that lists relevant specifications across the product spectrum:

It's a good read.


Enjoy.

Sounds good.


But I am not storing my guns in fruit syrup.
