This is a very versatile oil that I use to lubricate parts of my 3D printers to prevent premature wear. The careful to keep the bottle right side up or you will have a slick mess. This is easy to use and I have never had a reaction to it. Between this and super lube they only other type of lube I use is Mobil EP2 Grease for rails. I think with these three items you cover everything you need.

Used this on my sliding glass doors. Works better than anything else I tried.

I use this oil to lubricate the o-rings on my ac connections.

This is why the "Big Boy" use it.I won't bore you with all the parameters; you can look them up; I did. Start by downloading the MSDS.In its thicker formulations (above "100"), it seems to have a slightly different "feel" than the usual petroleum based oil but, as a lubricant, it works as well, has the same tenacity and the same temperature range. Or better. And it's non-toxic and breaks down when out in the environment (but not in your motor). Most all of their products are rated H-1 (use food facilities) by the NSF and a few are rated H-3 (food contact). I use their 68 weight, H-3 formulation, on my cutting board and carbon steel knives in my home and their 68 weight, H-1 formulation on my boiler motor. Not cheap; but what is your life worth?

Used this to lube my keyboard switches, work great! It is on the runnier side so control the amount is a bit difficult, but that's just a user error. I don't mind it though since I'm not so nit-picky and don't put tooooo much on accident where my switches start feeling squishy.Makes it easy to bag lube springs! This big bottle will last forever for multiple projects.
