My dad used to use real Whale Oil-- in little yellow cans with a whale spouting on the label.
Then there was Hoppe's #9 solvent and gun oil.
Then Break Free CLP- great for cleaning and freeing up dirty actions.
For gun oil- whatever's available on the shelf when I run out.
For copper fouling I recommend you all try Wipe-Out bore cleaner foam. Zero brushing of the bore. Keeps the copper fouling under control with less scrubbing, fewer patches and elbow grease. Smells good.
As far as oil, there are many new gun oils and they're all pretty good.
