I have been reading from different forums and sites that the use of synthetic motor oil is better then "gun oil" they say that it is the same thing but in a bottle with "gun" on the label and they charge you more for it. I also have read about "Ed's Red" has anyone mix this up and does it work as good as they say it does. Has anyone used motor oil or Ed's Red? What do you like/ dislike about it.
I'm a long, long way from being an expert, and any information I offer is based on my own experience, not on anything suggested by the uber-experts like ATR.
Ed's Red bore cleaner. It's a cleaning solvent that works well, it's inexpensive to mix up in quantity, and if you include the optional Lanolin in the mix it leaves behind a slight film of moisture repellent and lubricating lanolin. Lanolin is an amazing compound in its own right, and it's used in many lubricants, especially in marine environments. However, using Ed's Red is no substitute for proper lubrication, as Ed Harris says right at the beginning of his article.
Ed's Red does nothing for removing copper fouling, so far as I have seen, but is good for regular cleaning. The only downside to it, IMHO, is that it doesn't smell as nice as G96, LOL.
Synthetic oils and greases: I've used - when regular gun oil was not available - 0W20 (or was it 0W30) fully synthetic motor oil as gun oil. It flows freely at arctic temperatures and has good lubrication qualities. The key is to use as little as possible. Over-oiling just collects dirt and crud. Some people claim that ATF (automatic transmission fluid) is all you need to oil your guns. I'm skeptical about that claim.
I've also used low-temperature synthetic grease - sold for lubricating snowmobile bogies - with no ill effects. Synthetic greases formulated for arctic conditions do their job without gumming or caking. As with oil, just a trace of grease is all that's required - more is definitely not better.
Having said all that, there are any number of very high quality firearm-specific lubricants on the market, and given the small amounts required, one regular-size container will last most shooters for quite a while.
I can never understand why someone is prepared to drop 4 or 5 thou on a very expensive rifle (or even $500 on a good .22) , and then be unwilling to spend twenty bucks for the correct special-purpose gun lubricants.
