If you want to find an effective penetrating oil, you need to dig deep thorugh the popular penetrating oils available in the market. Penetrating oils can be a good help in maintaining and removing rusty materials and breaking rusted stuck nuts and bolts of machinery.
The top famous brands that will be discussed concerning the most economical and best value penetrating oil for rusted bolt and nuts are the following: Liquid Wrench L112Penetrating Oil, B’laster 16-PB Penetrating Catalyst, Kano Kroil Penetrating Oil, 3-IN-ONE 10038 Multi-Purpose Oil, and the classic WD-40 Multi Use Penetrating Oil. It is better to know the pros and cons of the individual product to be able to initiate penetrating oil comparison and to be able to see what to consider in specific situations.
What is Penetrating Oil?
You might have an idea on what oil looks like and what it does, whether it is used as fuel for transportation, or heat for cooking, or for creating specific products like plastics and other materials. Oil can be used as a lubricant to minimize friction. But not all oils can be used as a lubricant to loosen stuck rusted nuts and bolts; it’ll probably do more harm than good.
That’s where the penetrating oil for rusted bolts come into play. Penetrating oils have a low viscosity that enables them to seep between cracks and narrow spaces, leaving an oil film inside spaces. With reducing agents and anti-oxidants, the oil film left displaces other stored materials, cleaning the insides to help minimize friction and to be loosened freely without needing excessive force.
Functions of Penetrating Oil
The primary role of the penetrating fluid is to loosen and break frozen, corroded, or stuck bolts and nuts without the use of excessive force. With its low viscosity, it enables the fluid to move and enter into crevices, pores, and threads of any material that needs to be loosened.
Most of the penetrating oils are made of polymethacrylate, zinc dialkyldithiophosphate, alkyl succinic acid, tert-dibutyl-p-cresol, lower alKanols, lower alkyl benzenes, and methyl silicone in a stock of paraffin bright stock lube oil.
While penetrating oils are best known to loosen seized bolts and nuts, they also offer other benefits.
Anti-Corrosion and Anti-Rust
While there might be a debate on what is the best rust penetrant, it is known that penetrating oil can be an excellent anti-corrosion and anti-rust substitute. You can use penetrating oil for daily or weekly mechanical material maintenance. You can apply best penetrating oil for exhaust bolts, metal joints, spark plugs and other machinery regularly.
The reason behind this is its anti-oxidant agents that help prevent rust from accumulating. Wise people say, “Prevention is better than cure”. Why not start using penetrating oil to prevent rust, rather than using it to remove rust in the first place? This way, you can stop materials from corroding and getting rusty, resulting in a more efficient and extended life for your machine.
Penetrating oil best acts as a degreaser or a cleaning solvent, to remove contaminants like greases, tars, and rust. When the product mobilizes, the residue is now easier to remove using a clean cloth, more than just using plain water. Rust can even damage the material.
It is the best penetrant for rusted bolts and mechanical parts, with its anti-corrosive ability. It means that it does not only prevent, but also cleans rust. It can even stop the build-up of harmful particles that you may find in dirt and grease which can cause performance inefficiency of machinery.
Furthermore, there have been discovered instances where penetrating oil is used, like for quieting noisy hinges and suspensions.
Another non-machine-related purpose for penetrating oil is that it removes gum and adhesives that are stuck on the surface. If you want that sticky residue off, penetrating oil can surely get the job done. But use penetrating oil in removing adhesive with caution. With its high volatile chemicals, it can damage certain surfaces and materials.
Types of Penetrating Oils
Micro-Dispersant Penetration Oils
This kind of penetrating oil is fire-resistant. Solid lubricant particles are contained in a synthetic oil. Examples of these solid lubricants are boron nitride, graphite, and polytetrafluoroethylene. This explains the low friction characteristics present in oils.
Water Soluble Oil and Straight Oil Fluids
This penetrating oil is primarily used for mechanical purposes. This kind of penetrating liquid is liquid in form, with the oils emulsified in low water concentration. The soluble oil created with high water content is built for fire resistance. On the other hand, straight oil is highly flammable; it is composed of base minerals and often contains polar lubricants such as fats, vegetable oils, and additives such as chlorine, sulfur, and phosphorus. It is used in machining operations in an undiluted form.

The cons of Kano Kroil use are that its container shape differs from the other penetrating oil. It will take a while to get used to its shape, and that’s why a lot of people critique it.
WD-40 Multi Use Oil
The classic and iconic WD 40 specialist rust release spray has been an incredibly versatile product that every man with a toolbox should not miss. The name WD-40 takes its name from the 40 attempts the inventor had to make to get the water-displacing formula to work. Norman Larsen was the man to take the credit for the creation of the classic WD-40, which has been used since 1953. Since 1993, penetrating oil WD40 has been used in 4 out of 5 American households, and 80% of professionals have been leaning on it ever since.
WD-40 has been helping out in household maintenance since the past decades. Its advantages are that it is indeed the universal penetrating and lubricant oil for almost anything. The WD 40 penetrating oil review can be used to protect a bird feeder, separate stuck glassware and stuck ring, remove chewing gum from hair and other surfaces, clean toilet bowls and license plates, remove tea stains, clean guitar strings, loosen zippers, shine winterproof boots and shoes, and degrease your hands; and the list goes on.

A con of 3-IN-ONE 10038 Multi-Purpose Oil is that it cannot penetrate frozen, rusted nuts and bolts, unlike how PB blaster and Liquid Wrench easily can. Despite its top-notch cleaning and maintaining ability, it is sad to say that it can’t quite get the job done when it comes to penetrating rust.
With its new look, the container of 3-IN-ONE 10038 Multi-Purpose Oil has been transformed from a drip rim metal can into a plastic squeeze bottle. The new bottle design allows the smooth and controlled dispensation of oil with the squeezing of the bottle. Not every change is an improvement; reviews of the product claimed that the old design was working just fine. With the new design of 3-IN-ONE 10038 Multi-Purpose Oil, some customers claimed that the oil leaks onto the hands of the user.
With the top famous commercial penetrating oil available in the market as earlier mentioned and the active debate on the best and cheapest penetration oil, there are cases when people improvise and discover.
A new way of improvising and creating penetrating oil is to use a 50/50 mix of automatic transmission fluid and acetone. Another variety of penetrating oil substitute is vegetable oil and acetone, discovered by Drexel University Philadelphia, Pennsylvania engineering students. Both of these improvised penetrating oil is discussed.
Automatic Transmission Fluid and Acetone Mix
You might ask, “Does ATF and acetone work?” It has been used for decades by a majority of machinists and motorists, on their cars or in their houses. No one knows who’ll take the credit for the discovery. But one thing is for sure; it does work. It has already been a part of the life of a mechanic and the average Joe.
The transmission fluid and acetone mix competes in the search for the best penetrating oil for seized bolts. Ex-student and professional machinist, Bud Baker conducted a comparison test and published by Machinist’s Workshop Magazine in the May and June 2007 edition. With the organized subjective test among the top commercially branded penetrating oil products, and with the recording of required torque to remove the frozen nut, The ATF acetone penetrating oil had the number 1 spot, requiring a maximum of 53 pounds of torque to break the nut.
Vegetable Oil and Acetone
Good news for people who have no extra money for experiments, and people in the rural areas where varieties of penetrating and lubricating oil can be expensive and limited to one.
The Vegetable oil and acetone mix was discovered by Drexel University Philadelphia, Pennsylvania, engineering students. Comparison tests of WD-40 Multi Use Oil, vegetable oil mixtures, and ATF were facilitated by a professor of engineering in Drexel University, Alex Moseson. Moseson’s students tested the research of Pat Delany, an E4C key member, that the vegetable mixture can be as effective as branded commercial penetrating oil.
The test was conducted with vegetable oil mixed with 10% acetone. Acetone is an active ingredient in removing nail polish, and an alternative chemical for paint thinners. For a more efficient effect, more acetone was added at 30%. Just costing one-tenth of the price of WD 40, the comparison tests show the effectiveness of vegetable oil and acetone more than the WD 40 and automatic transmission fluid.
Do the math yourself; vegetable oil costs $2.63 per liter and Acetone, $12.12 per liter; compared with WD 40, the results state that the vegetable oil and acetone mix is a cheaper and more effective penetrating oil.
This might sound as good news to you, but in reader reviews, some people proclaim the consistency of WD 40 as a penetrating oil, thus, claiming vegetable oil and acetone mix, as an ineffective penetrating oil for rusted stuck bolts.
A comparative experiment was conducted by Machinist’s Workshop Magazine, May to June 2007 edition, on the top commercially branded penetrating oil and the 50/50 mix of automatic transmission fluid and acetone commonly called atf mix. With a measured torque meter, the commercially branded products namely, WD-40 Multi Use, PB Blaster, Liquid Wrench, Kano Kroil and acetone and transmission fluid penetrating oil were put to the test. The torques required to remove the nut from the scientifically rusted bolt were measured.
The result and ranks are as follows: No penetrating oil added = 516 foot pounds of torque; 5. WD 40 = 238 foot pounds of torque; 4. PB Blaster = 238 foot pounds of torque; 3. Liquid Wrench = 127 foot pounds of torque; and 2. Kano Kroil = 106 foot of pounds of torque. The number 1 rank was 50/50 blend of ATF and Acetone mix = 50 foot of pounds of torque.
The results made 50/50 blend of ATF and acetone mix the superior winner, and it is concluded that ATF acetone for rusted bolts can inevitably get the job done, although they were scientifically rusted.
The different commercially branded penetrating oil and home-made improvised penetrating oil were ranked according to their effectiveness and price.
The products were scored through the customer reviews on the internet and with the conducted comparison experiments.
Regarding the effectiveness as a penetrating oil, the ranks were as follows: 1. 50/50 blend of automatic transmission fluid and acetone mix, 2. PB Blaster, 3. Liquid Wrench, 4. Kano Kroil, 5. 3-IN-ONE 10038 Multi-Purpose Oil, and finally 6. WD 40 Multi Use Oil.
Regarding the effectiveness as lubricating oil, the ranks are shown: 1. Kano Kroil, 2. PB Blaster 3. Liquid Wrench, 4. WD 40 Multi Use Oil, 5. 3-IN-ONE 10038 Multi-Purpose Oil.
The effectiveness as a versatile, “jack-of-all-trades,” and all-around use oil, was ranked as follow: 1. WD 40 Multi Use Oil, 2. Kano Kroil, 3. 3-IN-ONE 10038 Multi-Purpose Oil, 4. PB Blaster, and 5. Liquid Wrench
The final scoring comparison was the affordability of the product, and the ranks were the following: 1. PB Blaster 11oz costing $3.76 2. Liquid Wrench L112 Penetrating Oil Spray – 11 oz. costing $6.71 3. 3-IN-ONE 10038 Multi-Purpose Oil 8 oz costing $7.23
- WD 40 Multi Use 12oz costing $14.04 and 5. Kano Kroil 8oz Costing $14.59
These were all based on the prices offered by Amazon.com
Some products were not included in the comparison because they were not considered to do be able to do the job and they lack tests of effectiveness; an example of this is the vegetable oil and acetone mix.
When the debate is all about the best penetrating oil, it all comes to its effectiveness, versatility, and price. A product wherein the pros outweigh the cons is accepted to efficiently get the job done.
The product that ranks the most effective regarding effectiveness as a penetrating oil, versatility, and affordability is the Kano Kroil Penetrating Oil 8 oz.
