I once saw a comparison test of a bunch of penetrating oils, and good old Liquid Wrench came out on top. I have Kroil on hand for various things, but it has gotten expensive, almost 3x the cost of Liquid Wrench. There's no way it's even twice as effective.

Once you get a handful of these disposable plastic pipettes, you'll never stop finding uses for them. Mark them with a Sharpie to reuse them with specific liquids. I like these with the long thin "whip" tip, and two larger diameters, as they can be trimmed for a specific application.

It’s funny to me that Liquid Wrench came out on top. I used it for 40 years, ignoring my friends recommendation of Blaster. I finally tried it and was instantly converted. It might not be as good as Kroil but it’s very good.

It was just one such comparison, but took a lot of trouble to design, set up and conduct.

I have seen at least one comparison that seemed carefully done, but don’t recall the winner. If you don’t want to get expensive stuff, try Blaster on a few jobs. I suspect it would impress you regardless of any tests that were done. It’s only about $5

The best penetrating oil - and perhaps the cheapest as well - that I've come across is "Ed's Red" or "Ole Red", or other similar names, ia home brew concoction of equal parts of:
ATF (Hence the Red in the name)
Kerosene (or diesel fuel, available at virtually any gas station)
Acetone (a potent solvent)
Mineral Spirits (or paint thinner)
This was originally developed by a gunsmith (Ed -----?) as rifle bore cleaner. I've been using it for years beginning on FJ40 Land Cruisers for which I think the term "rust" was invented. A handful of Cruisers I've owned for over 30 years have been driven year round on and off-road in mud, snow, salted roads, etc and I seldom try to remove a fastener until I've hit it with this stuff. For very rusty parts you can give multiple doses and let stand over night.

Do not put the stuff in plastic spray bottles as it will soften and distort, maybe even melt, the plastic. I use a cheap Harbor Freight pump-style oil can with a long spout.

Is Ed’s Red so good it would work on a Fiat?

Not so fast. "Ed's Red" (and its predecessors) had stuff in it not applicable to a penetrating oil. It was a rifle bore cleaner, and as such had to dissolve caked hard carbon deposits, for example, and also function as an oily rust preventive. Personally, I'd stick with inexpensive and ready-to-use Liquid Wrench or some other popular penetrant. But, if you are still intrigued by "Ed's Red", here's more than you'll ever need to know:

Brian,

As I said in my post I know what it where it came from and what it was originally used for so i am not "intrigued" by it. I am speaking from personal experience in using it for over 30 years and I have found it is an excellent penetrating solution for freeing rusted and corroded parts. The ingredients are what many people already have in their shops so mix up a couple of ounces and try it your self.

Pete, I didn't quote or refer to you personally, my post was more for the wider readership. That said, while I believe you that it works well as a penetrant owing to one or two ingredients in it, that doesn't mean all the ingredients are required for the penetration function, and almost certainly several ingredients are being wasted. Consider that to have "Ed's Red" one must brew it himself. I'm just pointing out the futility (and expense) of rounding up all four (or more, depending on which recipe one uses) ingredients, when in fact one (or more) are for bore cleaning and protection, not penetrating rusted joints. In particular, I question the acetone, in part because that's nasty smelly stuff I'd prefer to avoid if it's superfluous.

OK, I guess it's time to resurrect my old line about the penetrating fluid I developed. It was so good that I couldn't find anything to keep it in.
Some days it's just not worth chewing through the restraints.....

Reminds me of the 200lb plus guy in Walmart in full camo that I bumped into in the check out. I said Oh, sorry I didn't see you. He never saw my point either. This is Kentucky after all. TSC sells camo painted tools, must be a lot of them out in the backwoods.
If I had known I would live this long I would have pushed the envelope a little harder.

Brian,

The active ingredients are the ATV (detergent properties) and the acetone (strong solvent) but as you probably know acetone evaporates rapidly. I'm sure the kerosene is intended to restrict evaporation. I see mineral spirits recommended all over the place (maybe even in the Porsche manual?) for grease cutting. I personally had and have all of the ingredients in my shop and as I said I think many do as well. It's not like you have to run all over the place to find these and I wouldn't say "several ingredients are being wasted" as there are only 4 to begin with. You might want to check out this post on the Garage Journal board: https://www.garagejournal.com/forum/thr ... is.200247/
Here's what it says in a nutshell:

Machinist's Workshop magazine actually tested penetrates for break out torque on rusted nuts.
Significant results! They are below.
They arranged a subjective test of all the popular penetrates with the control being the torque required to remove the nut from a "scientifically rusted" environment.

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
