Understanding The Importance Of Commercial Truck Lubricants

Posted on

Keeping your commercial truck in top shape requires regular maintenance, which includes using the right type of lubricant. The lubricant used in your truck plays a crucial role in the performance and longevity of your vehicle. Not all lubricants are created equal, so it is important to understand the different types and how to use them properly. In this blog post, we will discuss the different kinds of commercial truck lubricants and their importance.

Engine Oil:

The most common type of lubricant used in commercial trucks is engine oil. Engine oil protects the moving parts of the engine from wear and tear by providing a barrier between the metal surfaces. There are different types of engine oil available, but the most common types are mineral-based and synthetic. Mineral-based engine oils are made from crude oil and are less expensive than synthetic oils, but they don't last as long. Synthetic oils, on the other hand, are more expensive but offer better performance and last longer.

Transmission Fluid:

Transmission fluid is another important type of lubricant used in commercial trucks. It plays a vital role in keeping the transmission running smoothly by providing lubrication and managing heat. There are two main types of transmission fluid: automatic and manual. Vehicles equipped with automatic transmissions utilize automatic transmission fluid, whereas vehicles with manual transmissions require manual transmission fluid.

Gear Oil:

Commercial trucks have differentials that require gear oil to keep them running smoothly. Gear oil provides lubrication to the gears, allowing them to operate effectively without causing too much friction. It also helps to manage heat and prevent wear and tear. There are different types of gear oil available, including mineral-based and synthetic. Synthetic gear oil is more expensive but offers better performance and lasts longer.

Hydraulic Fluid:

Hydraulic systems in commercial trucks require hydraulic fluid to operate effectively. Hydraulic fluid provides lubrication and helps to manage heat in the system. It also helps to transmit power from the pump to the cylinders. There are different types of hydraulic fluid available, including mineral-based and synthetic. 


Coolant is not technically a lubricant, but it plays an important role in keeping your commercial truck running smoothly. It helps to regulate the temperature of the engine and prevents it from overheating. Coolant is typically made from a mixture of water and antifreeze and needs to be changed regularly to ensure optimal performance.
