Ive used this for about 25 years, and its the best penetrating oil on the market. It doesn't work instantly, But it works almost every time. If a bolt is frozen, just soak it in this and wait. Preferably overnight, but a couple of hours usually does the trick.Ive used it on everything from frozen suspension bolts, to locked up engines with stuck pistons. It even works great for cleaning firearms. Only negative is that it makes a crappy lubricating oil, but ive got other stuff for that.

It is an excellent penetrating oil and has been of great help to me in more time I care to recall.The Kroil company has always been a fantastic innovator of lubricants that I can remember my father using since I was knee high to grapefruit.

Sure there are plenty of others out there that say they are good, but this company's longevity proves they are the real deal and can be trusted with your prized possessions.
