Default Oil - Detergent or Non-detergent

I understand the differences, but what is better for firearm lubrication when one wants to use a motor oil?

Dan, I'm not 100% sure but I think all commercially available motor oil offered today has a detergent component incorporated into it's formula. (It cuts down on the part numbers they need to stock.)

The general consensus through many forums is a good synthetic motor oil works fine. You just want it to stick to the metal. I personally use Mobile One, and I be danged if I know whether it is detergent or not, but it does a fine job. Much to Remington's shame I pour a little into my Rem Oil bottle every few months and I expect the quart to last for my shooting career. (one of the benefits of being old)

Most multi-weight and synthetics are detergent (picks up small particles that would normally not get caught in the filter).

Non detergent is normally a 30 weight used in 4 cycle gasoline engines like lawn mowers (no filter).

Is it better to "wash" away small particles with a detergent or use the small particles as an abrasive for a smoother action?

In all honesty, I don't think it will make a bit of difference. Firearms aren't like engines and really won't benefit from the detergents. I would use either one with no worries. You're going to find a hard time finding light weight engine oils without detergents.

FWIW, I use Joe Gibbs Hot Rod Oil. It's a mineral based oil with a high zink content and properties to help resist corrosion in engines that sit for extended periods of time. It's also available in synthetic.

Firearm is not going to care one bit if it's a detergent. About the only place you would care, would be in a non combustion pump, like an oil compressor.

I was curious. Thanks for the inputs.
