Proper lube is a vague term. I know using it on chains cleans it, so I don’t use it on chains.
It actually dries out too, resulting in eventual rust.
Roller chains for equipment: any type of oil of mess isn’t an issue. Used motor oil, ****** fluid, I don’t care. Lube is lube.
Bicycle and motorcycle chains: dry lube like graphite or Teflon.
O-ring chain or X chain: dry lube.
Door hinges: lithium, graphite, Teflon
Non-bearing Drawer slides: Silicone spray or Teflon
Bearings: grease
WD-40: for cleaning something you want to stay lubed, before applying some other type of lube.
You’d be amazed what you can use silicone spray for. I put some on my work bench to make it hydrophobic. And it’s perfect for around the house stuff.
Everyone seems to think there is a “best of all worlds” with oil when really it’s a case by case basis. Expensive high temp lube won’t help a bearing that runs slow, just like heavy motor oil won’t help and engine last longer than lighter oil. In an engine, the weight is determined by tolerances. Modern day machining practices make engine tolerances tighter, hence the ability to run lighter oils, that flow better.
Try silicone spray or Teflon, or even graphite in the cables on your yard equipment sometime.
Graphite will lubricate
Teflon will lubricate better and with a better longevity (but won’t refill itself at wear points like graphite will)
And silicone will make it hydrophobic.
Ever lube has a purpose it excels at.
