Many different lubricants are available. But what is the difference between fat and oil? And what about lubrication? Are these terms synonymous? What is fat and what is oil? What is a lubricant? Is it better to use fat or oil? WD-40 answers all these questions!

Grease, oil or lubricant: definitions

Each of the different lubricants is used for the maintenance of moving parts. But what is the real difference? To better understand each of these terms, we’ll take a look at their makeup in a bit more detail.

Grease, oil, lubricant: different characteristics

Fats and oils both belong to the category of lubricants. They are therefore lubricants.
There are three different categories of lubricants, namely: solid lubricants, liquid lubricants and pasty lubricants.

Oils are liquid lubricants: they are characterized by their fatty and liquid state which does not mix with water. The oils are mainly of animal, vegetable, mineral or synthetic origin. In general, oils are called lubricants.
Greases are pasty lubricants: they are characterized by their high viscosity compared to oil and their thick and greasy state.

Different lubricants: grease or oil?

So there is an important difference between fat and oil: the level of viscosity. But are there also differences in use? When should you use grease instead of oil and vice versa? Grease, due to its high viscosity, can withstand high loads and high temperatures compared to an oil that evaporates earlier. It will therefore be used for large moving materials subjected to extreme conditions, such as high pressures and large temperature differences.

Oil, on the other hand, will instead protect materials from corrosion, aging, and lubricating mechanisms that are not subjected to high pressures or temperatures.

Different lubricants of WD-40

WD-40 offers many different lubricants in its range to meet specific applications:

  • High quality silicone spray for moisture protection and compatibility with plastics and rubbers;
  • High quality PTFE lubricant spray for dusty conditions or as a solvent;
  • Lock spray for the small lock mechanisms;
  • Drilling and cutting oil for cooling and protection at high rotational speeds;
  • High quality white lithium grease for high pressure fittings.

WD-40 Bicycle

In addition to the various lubricants listed above, WD-40 has also developed a special lubricant for the bicycle. Are you a professional cyclist or do you have cycling as a hobby? Then the products below will make your life even easier!

  • WD-40 Bike Dry Lube: Lubricant for dry chains, evaporates quickly and leaves a protective layer against dust and other dirt;
  • WD-40 Wet lubricant: Lubricant for wet and muddy chains. This lubricant better protects the chain against corrosion and agglomeration of sludge and other dirt;
  • WD-40 Bike All Conditions Lube: lubricant for chains for more urban and less extreme use.

We hope you now know the difference between different lubricants and that you know exactly which specific lubricant meets your needs!
