Types of greases and their uses


What You Need to Know About Lubrication and Car Grease
The main difference between the lubricating fluids that your vehicle requires and the grease applications you might need. Here's a brief introduction to  what is grease, the three main types of greases available in today's market: AP, MP, and EP grease and their uses.

What Is Grease and What Is It Used For?


Grease, is a lubricant, it is much thicker than oil and is used in other areas of your machine or vehicle. Oil is normally used internally so it can flow through the different tubes and passages and works as part of a system or cycle that allows it to circulate as it lubricates. Grease, on the other hand, is thick and is used in areas that need lubrication without flow. Grease is semisolid and therefore it is great for irregular lubrication in areas that would not be protected by oil due to its inability to stay put. It is also ideal for protecting certain mechanisms against water and other incompressible materials. Such as when winterizing a boat and ensuring that certain components stay protected.


Factors That You Need to Consider When Selecting the Right Grease for Your Needs


Viscosity. Grease needs to have a high viscosity in order to stay put and continuously protecting a certain area or mechanism against the effects of friction. Viscosity is basically the thickness of the lubricant. Oil has a much thinner viscosity than grease as it is a fluid and grease is a semi-solid and paste-like. Grease is made up of three main components: oil, thickeners, and additives. Due to this, it is very important that you consider the viscosity of the grease you use. A very thin lubricant will not last very long in a heavy load application where there are slow moving parts. Likewise, a lubricant that is very thick and is applied to a high-speed electric motor will not be able to protect it and it is likely to overheat.

Base oil. The base oil of a grease can be either conventional or synthetic and it is important to note that there is a big difference in the results. Synthetic grease contains base oils that are synthetic. These offer excellent protection against oxidation and provide the most resilient coverage in all kinds of weather. AMSOIL provides a variety of synthetic grease such as their Synthetic Multi-Purpose Grease NLGI #2 that works for both heavy and light duty operations. It offers shear stability, thermal resistance, and oxidation protection. Contact Maints Tech Sales and Service today to verify the types of grease that best adapt to your needs and the requirements of your machine or vehicle.

Additives. In order to meet certain needs, grease has additives that enhance it and make it work better for certain situations. There are different types of additives but one of the most common additives ones is called molybdenum disulfide. This additive makes grease very resistant to extreme pressure applications and can usually be found in EP grease.

Thickeners. Although the base oil makes a big difference and helps to improve the reliability of the grease, the viscosity also matters. That is why grease needs to have a thickener that allows it to not easily disperse. Nowadays, most of the thickeners in grease are soap. More specifically, lithium. This thickener allows the base oils and additives and all other parts to bond better and act more efficiently to form a reliable grease.
The Difference Between Fluid Lubricants and Friction Protection Grease

There are several fluids that your car requires such as motor oil, brake fluid, transmission fluid, etc. Those fluids tend to protect the internal areas of the different components, and as the name itself states it, they are more liquid-like and flow faster because of their consistency. 

Grease is a more thick and solid-like lubricant that tends to protect more external areas of your vehicle. Grease's thicker viscosity makes it ideal for surfaces where it is necessary that the lubricant stays put. Due to its semi-solid consistency, it is easier for it to remain on the surface and to offer a more durable external protection. However, its initial viscosity can change with applied shear and it can become a thinner substance. This viscosity change known as shear-thinning is necessary for certain applications where a much higher viscosity lubricant is needed to act against the intensified levels of heat and friction.


There Are Several Types of Grease and Each Is Created for Different Applications and to Meet a Variety of Needs

There are several types of grease, and they each go by different names and classifications. The three main types of classifications are AP grease, MP grease, and EP grease. Each of these describes a type of grease but there are also many other names and applications. For example, the term car grease is very common and it can refer to different types of greases in general.

The 3 Common Types of Automobile Grease and Their Differences

AP grease AP stands for all purpose. It is a type of grease that can be used for all kinds of vehicle applications. It is well known for its corrosion and rust protection. The resistant thermal degradation it provides allows it to be an optimal option for all kinds of grease-lubricated vehicle parts. This type of grease tends to be lithium based and water resistant.

MP grease MP grease means Multi Purpose grease and it is generally for automotive, and light vehicle applications. It provides the right coating from elements and water and allows the parts to be well protected. AMSOIL carries some of the best synthetic greases for all types of applications. In fact, their synthetic multi-purpose grease is the best choice for all kinds of temperatures, environments and vehicle systems. It can be used in electric motors, roller bearings, gears, wheel bearings, universal joints, and many other areas.

EP grease Extreme Pressure grease is the kind of grease that is most stable and durable. It is much more resistant than AP and MP grease. It can be used under incredible loads and very intense pressure. EP grease provides a much more reliable protection because of its more solid consistency that adheres to the surface and creates an additional coat of coverage against metal to metal contact.
