I have/have used BreakFree CLP, Triflow, WD40, Eezox, Tufoil, Tetra, Lockease, and others. I threw out the Tetra oil as it cracks plastics. I use the CLP and Triflow less now except to clean and oil hand tools, as I've been using Mobil 1 75W90 for everything except for three items; I still use Lockease on locks, Eezox on my pocket knives, and Eezox and CLP on firearms.
The Mobil 1 doesn't seem too thick as it works well on my older (I think I bought it in the 70s) plain bearing Dremel, but I wouldn't use it on locks. It works a LOT better than CLP or Triflow as a lube.
I buy WD40 by the gallon as I use it for cleaning and short term protection on most large tools in the garage, including the mower top to bottom, but I don't use it as a lube.
