Yet it ranked second from last on the test. Other than heat, I don't think any of them do much to break loose a rusted bolt. Other than Liquid Wrench, most of them only reduced the breakaway torque by around 5%. Where the oils do help is in keeping a nut from seizing on a rusty bolt after it does break loose. Then, pretty much any oil will work.
