PB is OK. Kroil is good, too. For the best penetrating oil however, it's very easy to make your own. This is what I use when nothing in a can works. 50/50 mixture of transmission fluid with acetone. Has unlocked things that no spray has.

Which Penetrating Oil is Best? Let's find out!

It's a penetrating oil.

So don't money shot it all over the head and body of your work.

Neat. I have found Kroil to be better than PB.  It used to be called Airkroil and is a long time favorite of aviation mechanics who have used it to remove bolts not loosened for 50 years. Many years ago a story circulated that a mixture of trans fluid and brake fluid beat out Airkroil and everything else when tested with a torque wrench on a bucket of bolts and nuts soaked in brine and allowed to rust. I saw it reported in rec.aviation.homebuilt on Usenet in the 90's.

A study done by Machinist's Workshop magazine in their April 2007 issue looked at different penetrating oils to see which one did the best job of removing a rusted bolt by measuring the pounds of torque required to loosen the bolt once treated. If the study was scientifically accurate, it turns out a home brew works best! Here's the summary of the test results: Penetrating oil ..... Average load None ...................... 516 pounds WD-40 ................... 238 pounds PB Blaster .............. 214 pounds Liquid Wrench ...... 127 pounds Kano Kroil ............. 106 pounds ATF-Acetone mix....53 pounds"

I've used them all. And they have their place. I'm in the process of restoring a 1973 Toyota Land Cruiser and virtually every single nut, bolt, screw or fastener was rusted in solid, thanks to Nebraska winters and the salt used to clear the streets. No amount of penetrant and smacking the fastener will break them loose. At the power plant I retired from I would leave the control room to walk through the plant and would watch maintenance guys remove seized up fasteners. Often a torch would be enough for the job but often the only thing that works is to weld an old nut to the bolt. Weld it hard and get it white hot, let it cool for for a few seconds grab the welded on nut with channel locks/vice grips/or what ever you have and the fastener always came out. So, I did the same thing on the old Toyota. And every single fastener came out. All body fasteners are now stainless steel with anti seize Only the engine and critical areas get high grade fasteners and even then every thing gets anti seize.

OK article, but it left me wanting to know a lot more.

Where do they make it?  How much of it do they sell?  How about some CSBs from the author or the CEO?

WD-40 is for amateurs who don't understand that the primary ingredient is Kerosene.  The stuff in the can won't go bad since it's under pressure; however, my dad used to buy that crap by the gallon.  If it's not used it turns into a gummy mess until is gels.  Parts of the liquid solidify or evaporate.

I swore by PBlaster for years before switching to Liquid Wrench.  I've found it works much better.  My secret for dealing with severely rusted fasteners is to alternate propane torch heat and the penetrant.

CLP is the next best thing in the world.

I honestly believe people are fooling themselves with the 50/50 ratio of transmission fluid and acetone, because the two are as different as oil and water.  They can't mix, and it's can be verified by mixing some and letting the mixture sit where, in just a few moments, they separate.  Transmission fluid works fine all by itself.

Now, assuming the rusted fasteners are coarse threads rather than fine threads, the old mechanic's trick of melting a crayon or candle will help as the wax will work its way between the threads.

I had written out a long diatribe about penetrating oils and referenced the video you posted as well as AvE and that in both cases they found LW worked the best. I ended up picking up a can of it even though I still have a can of PB Blaster and have found it varies.

I still find heat is best and can't wait for the inductive bolt busters to drop in price.

There are maybe a couple of reasons why acetone could enhance atf's effectiveness, but with those reasons it seems like sequential application would be as or more effective than a loose mixture, anyway.

Inductive heaters are The Shiat for frozen fasteners.  Faster and much more precise than the blue wrench.

Liquid Wrench (Best performance)

He liked to tell a joke about how his air-conditioning was "four-forty" - four windows down, going 40 miles per hour. It was never explained why he couldn't go faster, though possibly that was because many of his cars simply couldn't.

No, it was because this is a common joke, and 40 mph has been the speed of choice since I first heard it back in high school.

In my personal experience Liquid Wrench works better than PB (and doesn't smell as bad), but it's all pretty much the same stuff I think.

I keep looking at them and they are slowly coming down. I can get one now on Amazon for $300cdn.
Maybe the next big project I have to do I will get one. The last time I really could have used it was when I went with tube fenders on my jeep I had to drill out 5 of the 12 bolts

Heat and cold. The dangerous part is heating the nut up but not so much that whichever lubricating oil you add it flames up. But I heat and then because I had access to dry ice I start freezing the bolt. It shrinks, that gives just a bit more room for the penetrating oil to sneak in along fine cracks. But nobody has mentioned the most important part. Lots and lots of loud cussing.

I used some pbblaster earlier this week to remove some labels from some bottles. Acetone wasn't doing it. I can still smell it even though everything has been cleaned up and thrown out.

Normally, I'd agree with you, but Master Byte Software was an actual software company with an Internet presence (in the late 80s/early 90s).

OK, so I have a related question...

I'm swapping front seats in my Cherokee, and of course, due to shiatty design, they're locked up. Gonna get some Blaster for that, but is there something I can do to prevent this in the future? Dip them in motor oil before putting them back in, use something more like WD40, since TFA says its basically parafin wax? Or is there some way to coat the underside, where the nut is tack welded on so that it is protected? A silicone spray or something?

I had a car that sat for 2 years once, pretty much outside all the time. The lugs on the wheels rusted and the wheels were literally stuck to the brakes. PB Blaster freed them in about 2 minutes, I was astounded, I had not believed the hype until I actually saw it.

If I am doing any repairs I have a habit of adding red loctite and copper powder to threads before putting in the fastener.  Undoing the fastener is someone else's worry.

Silicone would be OK, but what exactly are you trying to protect?  You say "locked up".  What's locked up -- the slider mechanism; the runners; the reclining mechanism?  Typically, the slide rails and any operating mechanisms should be greased with Lithium grease.  It's my preferred go-to since it doesn't harden in cold weather conditions like typical grease.
