What are the types of Automobile Lubricants?

Whenever we visit the automotive parts store or even the service center, we often come across a wide variety of lubricants. Lubricants have been used in automobiles for a very long time and play a crucial role in the smooth functioning of a vehicle. Lubricants also serve other secondary purposes such as corrosion reduction, maintaining running temperatures and can be vital in increasing the life of various engine components. 

Lubricants are usually oil-based, plastic, solid, or sometimes a combination of these. The most common type of lubricant is usually oil or grease, but there are other types that we may encounter. It’s important to understand the different lubricants and their distinct functions.

Here are the types of lubricants that one must surely know.

  1. Engine oilEngine oil is the most common type and also one of the most crucial automotive lubricants. Engine oil is responsible for the complete lubrication of the combustion chambers of the engine by reducing the friction of moving parts. A key role played by the engine oil is maintaining viscosity even at higher running temperatures. Engine oils usually contain several different additives such as dispersants, detergents, and anti-wear additives to increase the life of the engine components. Manufacturers often suggest changing the engine oil at regular intervals.

Common types of lubricants
  1. Gear Oil: Gear oils are mainly used for manual transmissions, transmission boxes, and differentials in vehicles. They usually have very high viscosity and contain extreme pressure additives containing phosphorus sulfur compounds to cope with the high-pressure movements. The Gear oil does not need to be changed as often as engine oil but has a much longer life and is often changed after 100,000 km.
Engine oil and grease
  1. Greases: Greases could be made from petroleum or synthetic products, thickener, and additional additives. It is similar to oil but its thickness makes it ideal for the lubrication of gears, bearings, and linkages. Some of the newer high-performance lubricants such as synthetic greases that are made of silicone have been successfully used in high mechanical pressure situations such as torque transmissions.
What are Penetration lubricants
  1. Penetration Lubricants: These are highly refined, flowy fluids meaning they are a low viscosity oil. They are usually in aerosol-type containers. They are being used on stubborn and rusted nuts and bolts. They are most effective when they are sprayed and are allowed to soak in. Penetration lubricants wear very fast and often need frequent reapplication.

what are Dry lubricants
  1. Dry Lubricants: They are an easy-to-use, mess-free form of lubrication. They are made of liquids such as water, alcohol, and dry lubricating particles. They usually come in an aerosol spray canister. Once sprayed the liquid evaporates and leaves behind a layer of dry lubrication. They are best used for smaller parts such as hinges and threaded rods that otherwise would get stuck with grease.

Understanding the importance of the different automotive lubricants and their distinct uses can help with maintaining a smooth and damage-free vehicle life. It can not only extend the life of the vehicle but also reduce repair costs on multiple engine parts and their components. Following up on regular maintenance will ensure all of the above. If you are unsure of what lubricant grades to purchase, you could either look in the owner’s manual or get in touch with your local service center.
