I agree 100%! I have all of the aforementioned fluids on the shelf in my garage except Engine Restore because I don't have anything with a tired engine. I love marvel mystery oil, add it to the fuel for all of my implements to reduce fuel system corrosion from ethanol gas. And PB Blaster is the best rusty nut buster for reasonable money (Kroil is great but expensive).

Lol, I am looking at some PB Blaster I took out of the passenger side of my truck so I could take my wife somewhere.
