My dear old dad laughed when I showed him a brand new $10 bottle of super duper gun oil. He claimed a good quality engine oil was every bit as good as any premium gun oil and explained why (pressures, temperatures, RPM, and duration between oil changes in an automotive engine). As he had been a chemical engineer, , tanker (1935-1938, 1939-1944) and firearms instructor (1944-45) I trusted him. I've used synthetic motor oil on guns (and motorcycles and cars) for over twenty years now and it works great! Where applicable use grease but everywheres else use synthetic motor oil. One guy in the club is an instrument mechanic and he also uses synthetic motor oil. It works great!
Oil is a piss poor choice for firearms lube. Run grease, it doesn't drip, burn, or blow off the gun.

Grease is designed to hold lubricants in place keep the them in place. It is designed for very high speed and high temp environments, something Guns are NOT, unless running absolute full auto, even then high speed is not very high speed. The reason most bearings are sealed is to keep dirt out, not in. If you use grease remember that the grease will not only suspend the lubricating chemicals it will suspend dirt, brass bits that blow off the casing, and any debris it comes in contact with. Grease is likely the worst gun lubricant you can use and will cause premature wear if you use it on sliding surfaces, unless you replace it very often and keep your weapons very clean.
Advising to use grease is very bad advice.
Keep in mind when lubing a firearm less is more, and most firearms function just fine when run dry. Not suggesting they be run dry, just saying don't over do it. and of course Motor oil is fine, just fine.
All true!Yes, but grease is even better on sliding surfaces. There's nothing magic about firearm-specific lubricants.
Your post is right full of fail. Grease is the choice of professionals everywhere. Regardless of the fact that SOME debris may be retained/suspended within the lubricant, grease unlike oil does not burn,blow, or drip off the firearm. As for less is more, you would be wrong again. I have yet to see an over lubricated firearm fail. I have however seen many under lubricated firearms fail. I'm not saying one should submerge their firearm in lube but, keeping your firearm lubricated is far more important than worrying about potential wear due to suspended debrisGrease is used in areas that see less than frequent service(speaking of non firearms use) and you're right, grease is often used in areas of high heat and high pressure. So where's the bad part in this equation??

Yes, dont drink the ATF, or any oil that isn't vegetable or animal based. You probably shouldn't lick your guns either. What's your point? Wd40 is a water displacement product, not a lubricant, it doesn't work as seasoning either.![]()
I've posted this before, and I'll post it again every time this topic comes up. G96, I use it for lube, cleaning, everything, on all my firearms. I've never had an issue with corrosion or an issue with function (due to lack of lube) since using this product. Use whatever the hell you want as lube, but this is convenient, cheap, and designed specifically for the purpose. YMMV.

Nothing designed to do three things does them all well.
For cleaning, a specific carbon cutter, for copper; a copper remover, Mobil1 for lube, and a grease like cosmoline for preservation/storage.

True but viscosity and what some lubricants do in various temperatures should be considered....
Nothing designed to do three things does them all well.
Up here if hunting with a semi in mid winter with -40C grease would be equivalent to mortar, binding everything solid and rendering your firearm completely useless. Add to it that snow "dust" while travelling on snowmobile will adhere to it further compounding the problem.
In this case a very light oil would be recommended. I usually leave my bolts DRY in this hunting situation or coat them with dry-lube which leaves a teflon film on it. Way better than oil as snow dust won't stick to it and much much better than grease as there is nothing in it that will thicken up.
Obviously once the trip is over the firearm is stripped and cleaned then lubed accordingly.
