For those of you unfamiliar with "Project Farm" videos, they are of a man who tests various consumer products, somewhat of a one man Consumer Reports. There are others who do this as well, but Project Farms tests are consistently based on reproducible tests.
Here is the first phase of penetrating oil/lubricants. There is a part two, which I will post later that tests additional brands. Part 3 is a showdown of the top two winners of the previous tests. BTW, As some have previously mentioned, WD-40 is technically not a penetrating oil (he calls them penetrating "fluids,") but it is included in his test/review.

Many years ago I started out with Liquid Wrench I bought at the auto parts store. It worked well I thought until I started working in the truck/trailer industry and we had a Ryder Truck Rental shop around the corner. One day a tech brought me over some Howes penetrating oil in a pump sprayer. They bought it in 55 gallon drums. That was the best stuff I used until I got turned on to PB'laster when it was made by the William K. Westley Co before they sold out. That was my go to until a friend that works at Pratt & Whitney started bringing me home cans of Knock Er Loose by CRC and that became my favorite. Then I was working at a John Deere dealer after switching careers to lawn & garden repair when the service manager brought in a small 8oz squeeze can of Kroil with a pin point nozzle his brother gave him to clean his guns with but he didnt like the smell so he gave it to us. I immediately discovered a little goes a long way and I've done some incredible things with that stuff over the years that was very rusty. I also use it to drill holes in steel to keep the bit cool and also to tap new threads. I was buying the same containers off eBay until the stuff started to get very expensive a few years ago so I stocked up on a dozen cans once when a seller had them crazy cheap. Luckily my friend at Pratt started supplying me with Aero Kroil cans he gets so Ive been using those. I know it didnt come out on top in those tests but Im sure gonna stick with it, even though I can still get the Knock Er Loose for free as well. As far as WD40 goes its great for wet ignitions and thats all I use it for. Thats all its really good for with all the other options out there. |

Ever since I used it to free up a pair of needle nosed pliers about five years ago. An HVAC tech left them at our house, and we found them about a month later, after having sat out in the rain and rusted just about completely solid. After leaving them in the garage to marinate for about a year, I re-discovered them when I needed a set of pliers, and couldn’t find my regular ones. By this point, I could only get them to move to two positions; almost completely closed and almost completely open, no middle ground. As soon as I sprayed the joint with the liquid wrench, it freed up. I continue to use those pliers to this day, and haven’t had any issues with the joint since.

Ok, ok, so I am not a professional mechanic. I use PBlaster and Zoomspout for everything. They work. Something must penetrate! |

"The chance of success or failure depends on the technique and tools used by the person attempting the disassembly"
Dave, I couldn't have said it better myself. When a penetrating oil is used for disassembly, I often think of it more as a temporary lubricant for the exposed threads, more than the oil attempting to get past the first round of threads within the tapped section or nut. Also, where applicable, heat via a torch is king. Ben |
