Penetrating oil also referred to as penetrating liquid is a low-viscosity, petroleum-based lubricant. The best penetrating oil does usually have low viscosity. Therefore, it flows effortlessly when applied on affected parts.
Penetrating oils got their name from their capability to penetrate/enter in the narrowest spaces in the middle of the threads of two parts. These oils usually displace other materials and leave a thin coating of oil in the surface pores of a given object.
Though they can be used for general lubricating purposes. This is not entirely wise due to the oils’ volatile nature. Normally, they vaporize in a very short period of time. Thus, they leave behind very little lubrication remains.

Composition of Penetrating Oils
Generally, penetrating oils are made of a mixture of methyl silicone, zine dialkyl thiophsphate, polymethacryalate, tert-dibutyl-p-cresol, alkyl succinic acid, lower alkyl benzenes, and lower alkanols in a stock of kerosene bright lube oil.
The alkanols elements are normally included as lower alcohol variations, such as propanol or methanol. Tax and economy purposes call for a mixture of methanol and isopropanol in a ratio of 1 to 5.
Bright oil base is normally developed from a mixture of natural paraffin oils that are typically pre-treated for high viscosity and low viscosity lubricants. Antioxidants and reducing agents are those regularly added to oils for motors and may vary in quantity when used in penetrating oils.
Types of Penetrating Oil
Micro Dispersant Penetrating Oils
This kind of penetrating oils have solid lubricant particles that exist in a synthetic or natural oil base and are fire resistant. The particles of the oil can be of any variety of solid lubricant. The best examples include polytetrafluoroethylene, graphite, and boron nitride.
Straight penetrating oils are the ones frequently used for mechanical applications. These are non- emulsify oils made from base mineral lubricants with esters, fats or extreme pressure additives, including phosphorous, sulfur, and chlorine.
Synthetic or Semi-Synthetic Fluids
Semi-synthetic and synthetic penetrating oils and penetrants are composed of synthetic compounds, such as: blends of synthetic fluids and water; chlorofluorocarbons, di-esters, esters, poly-glycol, and silicone.
Emulsion/Water Soluble Fluids
Emulsion and water soluble liquids have a very low concentration or a high dilution and consist of high water content fluids. These penetrating oils and penetrants are usually used in a diluted version with concentration percentage of up to 10 percent.
What Do You Use Penetrating Oil For?
Penetrating oils are regularly used in energy, automotive, and manufacturing firms. As far as standard uses are concerned, there are three general applications:
- As an anti-corrosive coating or as a water repellent
- Loosening trends on axles, seized bolts and other fasteners
- Oiling sensitive or fast moving machine parts
The low viscosity nature of penetrating oils allow them to lubricate parts without resistance. It is typically easier to apply as well as reapply the best penetrating oil with aerosol spray, especially too hard to reach places.
Low viscosity oil seeps deep into the narrowest places when you apply to stuck threads. This helps to loosen encrusted deposit and free the pieces. A good penetrant will help to easily loosen tightly fit moving parts, especially ones that make noise.
The top penetrating oil for rusted bolts are effective at protecting aluminum and iron from rust. This is so since the oil has a trend of expanding across the applied surfaces in a uniform coat and it’s capable of repelling water molecules.
Penetrating oils are made up of hydrocarbons with up to 20% in liquefied carbon dioxide and an exception of 10% to 15% in inert materials. One of the outstanding nonpolar solvents, which is normally liquid under normal conditions is hexane.
Water, which is a polar solvent, is typically effective at breaking up and dissolving specific substances, including metal ions, sugars, and salts. However, water is useless at dissolving non-polar solvents (plastics, fats, or oils).
For that reason, penetrating oils can be used to get rid of:
- Spray paint
- Acrylic paint
- Dripped varnish
- Permanent marker, stickers, chewing gum, and among other troubles that cannot simply be broken down by water.
Top 8 Best Penetrating Oil Reviews 2019
The Kano Kroil is the best penetrating oil for rusted bolts. It penetrates and loosens frozen metal parts in minutes. It quickly loosens rusted bolts and nuts.
Kroil penetrates to 1 millionth inch spaces, dissolving and preventing rust without attacking the metal. The oil displaces water, dissolved gum, dried grease and provides lubrication.
Kroil has a unique chemical structure that was engineered chemically in a laboratory. This defines the interdisciplinary electrical, physical, chemical mechanical properties that work well with joint metal parts.
The scientific principle behind Kriol’s working is that it reduces surface tension and creeps in. The oil has a unique molecular architecture creating an affinity to the metal. This product loosens every frozen inch of the metal.
Kano Kroil Penetrating oil is pretty expensive to acquire. To save on money if needed every now and then, do not pour so much of it to avoid spilling and make sure it stays in its can.
What Are The Uses Of Kano Kroil Penetrating Oil?
You can use the oil on mowers, tractors, autos and gun. It can easily loosen a bolt or a stripped screw stuck together with rust. It is the best thing when it comes to dealing with firearms.
It also works on brass and aluminum threads and can resolve frozen fittings of objects such as cameras.
How is Kano Kroil Penetrating Oil Used?
Using Kano Kroil is a simple task. You will need cotton ball to make rusting easier. Put the ball on the mouth of the bottle and fill it with Kroil. Put the ball at any place you want rusting to be prevented. I find just two drops of the oil sufficient to deal with metal rust.
To sneak penetrating oil into tiny or confined spaces, you need a narrow mouthed bottle with droppers or spouts. Pouring into the holes increase risk of spilling. Suppose any given object is loaded corrosion and is frozen or seized, Kano Kroil penetrating oil will deal with it.
This penetrating oil is far better than the other varieties in the market. Every household should have this amazing stuff to get rid of corrosion or rust any time.
- LONG LASTING LUBRICATION: Leaves a thin, wet film that provides long-lasting protection and lubrication that won't run, freeze or melt off easily. Use in high friction areas.
- DISPLACES MOISTURE: The rust penetrating oil actively displaces water off the surface. The thin consistency of car lubricant oil displaces water faster than conventional formulas.
- RUST PROOF PROTECTION: Brake lubricant leaves behind a highly water resistant protective layer which helps prevent corrosion and rust from forming. Chain lubricant soaks down into the gaps.
- SUITABLE FOR USE IN TIGHT PLACES: Penetrates openings as small as one-millionth of an inch. The low viscosity of soaks deep into gaps to break the bond that holds stuck parts together.
- INDUSTRIAL QUALITY: Penetrating Oil is designed with industrial strength. It is a trusted tool used by professional tradesman. It is used by numerous Fortune 500 companies.
The PB Blaster busts loose frozen or rusted parts caused by corrosion and rust in minutes. It contains a non-evaporating lubricant, which saves time and also protects against further corrosion and rust. The spray works on rusted nuts and bolts. Spray PB on the required part and let it sit for a while.
This concentrated penetrant creeps up, spreads and surrounds into hard-to-reach spaces, allowing parts to escape surface tension of corrosion and rust. The spray offers hardworking, top-quality formula which leaves behind a lubricating film to prevent further rusting.
The penetrating catalyst can be sprayed as a mist. It is so fine that it will find even the smallest openings in between metal parts penetrating them within a short time. It seeps into almost invisible crevices loosening metal connection that appeared rusted solid over time.
Lots of fumes when the product is used. Consider using it in open space or leave any openings wide open to ensure air circulation.
How Should Blaster 16-PB Penetrating Catalyst Be Used?
After spraying PB Blaster on fused parts, give it several hours or even the entire night to sit for the penetrating oil to seep in. You can then use your wrenches to loosen the parts a little bit. If they will not budge, try a second heavy dose of the oil and let it sit for a while.
I consider using heat on very stubborn parts to make them loose. For instance, a stuck nut warmed using a heat gun will automatically expand enough to enable your wrench to turn it.
Remember not to apply direct flame to parts still wet with oil as the oil will evaporate rather quickly. There is also a possibility of igniting the oil as it is petroleum-based.
What Are The Uses Of Blaster 16 PB-Penetrating Oil?
PB Blaster can be used on automotive, plumbing, marine, industrial and other equipment. You may need to apply it 1-3 times depending on stuckness of the stripped bolt or rusted nut. I find it best to apply 6-12 hours apart from each application to effectively soak in at molecular level.
The penetrating catalyst is useful, especially when you have rusted or corroded nuts or bolts that will not budge. It does a good job on any rusted projects.
The spraying can may run out of pressure before the can is emptied. About half of the product is wasted. Therefore, use it well on required parts to save on money.

Best Penetrating Oil Comparisons
You should only spend more money if you are getting more value. With that said, I conducted a number of comparison tests to find out which one is the best penetrating oil for a given task. Here are the findings.
Silikroil vs. Kroil
Silikroil is an additional formulation of Kroil that provides some of the same benefits. Silikroil combines penetrating oil with dimethyl silicones. A Silikroil surface will repel moisture or water; thereby, avoiding corrosion.
Kroil is a high performing penetrating oil. Its unique patented molecular architecture develops an attraction to metal that warranties swift penetration. It also maintains a molecular design that has the ability to break bonds, usually at the first molecular level.
Generally, Silikroil is a formulation of Kroil. The only major difference is that the composition of Kroil does not include silicones.
PB Blaster vs. WD-40
WD-40 is credited with numerous uses as a lubricant and a penetrating oil. However, is this really the case? I conducted a comparison test between WD-40 and PB Blaster to determine which one is best.
These two oils are things that you can get from local hardware store. To begin with, you all know the WD-40, which comes with a built-in straw. The PB Blaster; on the other hand, comes with a straw attached on the side.
In the test, I aimed to do a detailed grease and penetrate. The first thing I did was a spray test on a vertical black board. I sprayed the WD-40 on one side and the PB Blaster on the other with the straw attached to each can.
The WD-40 sprayed a light whitish fluid that is less viscous and flows quickly. On the other hand, the PB Blaster sprayed a thick whitish fluid with a high viscosity. As far as the spray test is concerned, the Blaster was way thicker than the WD-40.
The next test I conducted was a penetrating test. To do this, I sprayed WD-40 on one side of my vise bolt and the PB Blaster on the other side. The WD-40 penetration was remarkable compared to the PB Blaster.
Another penetration test involved a thirty pound weight to see how much of each oil could penetrate underneath the weight. I released a one second blast at the bottom of each weight. When I lifted the weights, WD-40 is the one which did a lot of penetration. The PB Blaster did very little penetration.
It is clear from the above test that WD-40 is thinner than the PB Blaster. However, it is also clear that the WD-40 offers superior penetration than PB Blaster.
Kroil vs. PB Blaster
This two oils work in almost similar manner. The only thing that makes the PB Blaster appear inferior when compared to Kroil is the odor. The Blaster has an odor that is relatively problematic to wash off. Kano Kroil is considerably less unforgiving.
Unlike PB Blaster, Kroil has the ability to penetrate tight spaces, breaking rusting, compression, or tainting bonds. Its ability to reduce surface pressure allows it to creep in to places effectively. It also warranties no risk of rusting, thanks to its anti-water properties.
I did also put the two oils to test to prove their effectiveness. For this particular test, I decided to use rusted nuts and bolts. I took two test pieces, labelled 1 and 2, and they both had the same level of rusting.
I gushed Kano Kroil on the first piece and the PB Blaster on the second piece. I noticed that the Blaster oil was bubbling around the edges of the nut. I let the oils penetrate overnight. The two pieces looked like they had the same level of penetration on top of the bolts.
The following morning, I used a breaker bar to undo the bolts on each piece. The one soaked with Kroil presented less resistance compared to the one soaked with PB Blaster. I noticed that the lubrication of the Kano Kroil was higher. On the other hand, the PB Blaster appeared less oil like and dryer.
Kroil vs. WD-40
Both of the two are indeed universal lubricant and penetrating oils for almost anything. However when comparing Kano Kroil and WD-40 on rusted bolts and nuts, Kroil does a better job. Kano Kroil performs well in rusted machinery, breaking up rusted, frozen and joint nuts and bolts.
Unlike WD-40, Kano Kroil has the ability to hit any corrosive impediment breaking it down, allowing it to act as a lubricant, releasing rusty nails, nuts, bolts and fast quickly and efficiently. Regardless of WD-40 taking a longer time than Kroil, it lubricates metal surfaces for longer lasting protection.
To prove that Kano Kroil works better and efficiently, I did a nail climb test. I bought a can of WD-40 and Kano Kroil and used them on rusted nails. I set aside two nails with the same level of rusting. To determine the penetrating ability, the nails would help me evaluate how quickly the fluids will move up.
After timing, I noticed that Kano Kroil travelled up the rusted nail 50% faster than WD-40. Therefore, penetration and climbing up ability of Kano Kroil is much higher than WD-40.
PB Blaster vs. Liquid Wrench
To compare the PB Blaster and the Liquid Wrench, I decided to do a front and rear brake job. This job involved removing the calipers completely because I was going to paint them.
I sprayed the PB Blaster on the driver’s side. On the passenger side I used the Liquid Wrench. The calipers soaked with PB Blaster broke faster compared to the ones soaked with Liquid Wrench.
Liquid Wrench vs. WD 40
I usually use the WD-40 for milling aluminum, drilling, and cutting. I decided to test its performance in comparison with the Liquid Wrench.
As far as the initial test is concerned, the Liquid Wrench seems like the real deal. However, it is darker in appearance and smells a bit different when compared to WD 40.
As much as freeing rusted nuts and bolts is concerned, I chose to go with Liquid Wrench and not WD 40. This is so, since the Liquid Wrench presents superior penetration. Nonetheless, I would recommend the WD 40 for cutting fluid.
3-In-One vs. WD 40
Both penetrating oils are made as well as distributed by WD 40. Most of you would say that the two oils are exactly the same, but WD 40 is highly priced.
I would not say for sure that they are completely similar, but the WD 40 performs better as far as loosening gum on parts is concerned.
For a more effective comparison, I used both oils to clean an old steel bar. The best penetrating oil between the two as far as cleaning the bar is concerned was the 3 in 1.
Based on the findings, I would recommend the 3 in 1 for lubricating, cleaning, and reducing friction. I would recommend the WD 40 for freeing sticky mechanism, loosening rusted parts, driving out moisture, and cleaning.
Penetrating Oils FAQ
These are the most frequently asked questions (FAQ) by people who intend to know more about specific Penetrating Oils for them to purchase the best penetrating oils on the market today. Most of the questions are answered in the article, but here is a highlight of a few questions and their answers.
What is the Difference between a Lubricating and Penetrating oil?
Penetrating oils are effective at freeing stuck locks, bolts, and nuts that normally contain corrosion and rust. On the other hand, lubricating oils are effective at protecting and preventing parts from getting stuck.
Is Penetrating Oil Flammable?
A great number of penetrating oils have very low flash points that cause high flammability rating. One of the oils that is known to have a higher flash point and is practically non-flammable is Lawson non-flammable oil. This oil has quick penetration compared to the competition.
Which Penetrating Oil is Suitable for Cleaning a Barrel?
I choose Kano Kroil as the best penetrating oil for cleaning a barrel. The moment I have finished shooting, I wet the barrel with Kano Kroil and leave it for a few days. I let the barrel lie horizontally and turn the rifle over onto the other side twice a day.
It has happened that after I had done this to a barrel and pushed a patch through a few days later, long threads of copper came out of the muzzle. Therefore, it is important to clean a barrel before shooting with it again.
What Does WD-40 Stand For?
WD-40 refers to Water Displacement, 40th formula. WD-40 is the 40th attempt to make a Water Displacement chemical and is very useful for lots of jobs. This penetrating oil has five basic properties: penetrates, cleans, lubricates, displaces moisture, and protects.
Will Liquid Wrench Penetrating Oil Prevent Rust?
Yes, it will. The Liquid Wrench will prevent parts made of metal from rusting, thanks to its corrosion and rust inhibiting properties.
What Are the Formulations of Kano Kroil?
The Kano labs has two additional formulations of Kroil available that provide some of the same benefits. One is Silikroil, which combines dimethyl silicones and penetrating oil. The other is Penephite, a combination of penetrating oil and graphite.
What is the Best Penetrating Oil for Seized Engine?
WD-40 is one of the oldest remedies for lots of frozen parts, but there are other better solutions. Kano Kroil penetrating oil is about the best there is in the market. Usually, when I use Kano Kroil, it frees up my seized engine in a duration of 1 to 24 hours.
Is Penetrating Oil Harmful to Plastic?
In most situations, penetrating oils will not damage or harm plastic materials. However, there is a certain form of plastic that might get dissolved or damaged. The best thing to do is avoid the usage of penetrants on polyurethane.
There are many penetrating oil brands in the market, and choosing the right model may be challenging for some people. However, this does not have to be a difficult proposition.
I cannot say for sure which one will be the best penetrating oil for your application. This is so, since each and every one of these penetrants acts differently on different jobs.
To help you choose the best product, I have selected and reviewed the best penetrants on today’s market. They are all high-performing choices, considering the quality and price.
Personally, I would recommend the Kano Kroil for most applications. In a number of comparison performance test, Kroil prevailed against all others.
But this should not limit your choices. Other tests I conducted revealed the highlights and drawbacks of the other reviewed penetrants. So, there is one that will definitely work for you.
