Kroil is "GOOD STUFF" best penetrant by far
Best penetrating oil on the market by far! I've been using it since the 1960s when it was only available to industry. I'm glad it's readily available to all of us today. It really does lossen frozen fasteners in cars, boat engines, motorcycles, farm equipment, ect. I also works as a firearms bore cleaner when mixed into bore cleaning solvents (25% Kroil/75% Bore solvent.) The Kroil "creeps under metal fouling in the barrel rifling loosing it for easy removal. Kroil is just "Good Stuff"

It's magic
This stuff works. Gets under corrosion and breaks its' bond within the joint. Good for treating valve stems. Mineral deposits sluff off because they can't stick anymore.

They Say Kroil Is Made by Squeezing Leprechauns - I Believe It.
I’ve used a lot of penetrating oils over the years, but Kroil Original really does live up to the legend. I’ve been using it on your run-of-the-mill rusted nuts and bolts, and it works like magic. A few drops, a little patience, and things that should’ve snapped loose years ago finally start moving again. They say Kroil is made by squeezing leprechauns - and after seeing how it creeps into threads and breaks loose rust, I’m starting to believe it. The drip can make it easy to apply precisely where you need it, without wasting half the can in overspray like aerosols. It’s not cheap, but a little goes a long way. If you’re working on anything that’s been sitting in the elements - old cars, farm gear, or just corroded fasteners - this stuff is worth every penny.

Great Penetrating Oil
Great product, it does have a familiar and specific smell - it will somehow get on your hands. It does the job but needs a little time to penetrate.

Worth every penny!
Kroil is, hands-down, the most effective penetrating oil I have ever used. I was trying to drive rusted pins from a cylinder and they would not budge, even after liberal application of PB Blaster. I tried a few drops of Kroil, waited 10 minutes, then added just a little more and the pins started moving! It's amazing stuff and just a dab'll do ya!
