Every once in a while, someone, somewhere pulls off an idea of pure brilliance. How in the world did we not think of this sooner?

Honestly, I'm no mechanic, but I pride myself on doing my own up-keep. Oil, fluids, sensors, plugs, etc... How in the world was this not a 'thing' in the 90's when all the technology starting coming home with us? An oil cartridge you pop in and out like a printer cartridge. It's brilliant!

Mind - Blown.
