Ford E250 van w/ 8 bolt wheels ... bolts & lugs rusted solid ... 350lb torque impact wrench wouldn't buge 'em. Tried WD, Liquid Wrench, PB Blaster, with success only after blowtorch heating and much effort. Bought some Kroil online to try. Sprayed on, waited 15 min. and the impact wrench spun 'em off no problem. I was only doing one wheel at a time so the Kroil was not in conjunction with the other penetrants.

I used Kroil to remove the upper Oxygen Sensor on the exhaust manifold of my car. These are notorious for being difficult to remove. I put on the Kroil and let it sit for a few minutes and the sensor unscrewed very easily. It practically fell out of the hole. I was impressed.
Note that this can comes with a small plastic spout. You can't see it from the photograph. The spout is snapped in upside down, inside the can for shipping. You pop it out with a Phillips screwdriver and snap it in, cut off the tip, and you're ready to go. It comes with a screw-on cap. This version of Kroil can be legally shipped to California, unlike the aerosol version.

The best stuff on the planet. FAR superior to PB, Liquid Wrench, etc. Give it some time and just about ANYTHING will come loose. I buy it by the gallon!
Honest reviews on Kano Kroil Penetrating Oil, 8 oz. liquid (KROIL)
I first learned about this product back in the late 70's when I worked for the Navy. This product was not available to the general public so it wasn't widely known. This stuff is the Bee's Knees! We used it for taking stuff apart that had been exposed to a seawater environment so it was pretty important that it worked as advertised because a lot of the stuff we took apart was very expensive and/or delicate. Compared to other products on the market that make similar claims to their effectiveness, Kroil comes out on top every time. If you are looking for something to get that stubborn, rusted together part to come loose, look no further than Kroil.
My experience level is journeyman machinist, so I know what I'm talking about.

A friend recommended this for cleaning black powder and regular firearms. It is the most awesome stuff for breaking free stuck parts I have ever found. I will never have to ruin a screw head or bust up another part trying to take things apart to clean them properly after one of my competitions where I fire hundreds of rounds. Anyone who has wrestled with a stuck part knows where I'm coming from, especially when that part may cost a bundle to replace.
