INOX’s range of lubricants and greases have hundreds of uses across pretty much every industry or manual job. We confidently say that a can of INOX will help make any job easier. All of our products are made with quality ingredients to give you the best results. Because of this, it’s sometimes hard to choose one great product over another. 

One of the most common debates among our customers is INOX-MX3 vs LANOX-MX4. Both are superb multipurpose lubricants, so the line that separates them can seem blurred. But we’re here today to put their strengths to the test and show which is right for you. 

Discover the difference between MX3 and MX4


Qualified For The Same Jobs – But Excel In Different Areas 

Think of INOX-MX3 as the ultimate all-rounder. It’s perfect for all odd jobs where anti-corrosion and lubrication is needed, but sometimes the heavier, longer-lasting LANOX will give you more durability. MX3 leaves less of a film and is ideal for lighter applications, such as delicate machinery, electrical work, hobbies and more. LANOX can endure more brutal climates and humid conditions. 

INOX-MX3 is our signature multipurpose lubricant. It is made with high-grade white oil, rust inhibitors and other components to give lasting protection from corrosion and oxidation. MX3 helps moving parts operate smoothly, penetrates through parts that are stuck together to help loosen and easily free up without causing damage and dissolves corrosion, oxidation and salt/grime buildup. A touch of INOX is beneficial no matter the job, except for regular use of soft plastics and rubber parts (which INOX-MX6 is better suited for). 

LANOX-MX4 has all these features but is particularly tough. MX4 is made from Lanolin, a natural wax found in animal wool. Although INOX-MX3 is a quality anti-corrosion lubricant, there are instances where a lanolin-based lubricant like LANOX is better suited for the job. LANOX will most likely cost you a few extra bucks, but will last longer and need less-frequent applications. The wool fat base gives things coated in MX4 a durable hydrophobic coating. The lanolin base helps to prolong the protection between applications, as it is a natural anti-corrosion compound that is not soluble in water and leaves a protective film behind.




Where To Switch Them Out 

If you’re looking for a night and day difference between MX3 and MX4, you’ll struggle to find one. For 70% of jobs, these two lubricants are interchangeable and will both excel at giving you market-leading lubrication and protection. So you may be thinking, “what jobs should I prioritise one product over the other?” 

MX4 is particularly resistant in coastal environments or high-humidity areas. We recommend using LANOX for all your marine vehicle lubrication tasks (such as boat, boat trailer, etc.) and then using MX3 for areas where a clean, controlled lubricant application is needed (such as fishing reels, gears and tackle). 

We like to think INOX-MX3 is perfect for touch-up jobs and fast fixes, while LANOX-MX4 gives you an enduring protective coat for equipment services.


In the MX3 vs MX4 battle, there are two clear champions! There are no wrong answers with either of these products. Even if one product is better suited for a situation, the other will still do a fantastic job.
