Semi-trucks, also known as 18-wheelers, are massive behemoths on the road. These large vehicles can weigh up to 80,000 lbs and often have multiple axles.
As such, semi-trucks consume vast amounts of oil in order to keep their engines running.
In general, semi-trucks use a type of motor oil known as heavy duty diesel engine oil. This specific oil is made up of synthetic additives and special detergents that help keep the engine running efficiently while providing extra protection against corrosion.
The type of oil used in a semi-truck’s engine depends on its age and type. For example, older diesel engines may require a different type of oil than newer ones.
Additionally, some semi-trucks may need to use a different type of oil depending on the climate they are operating in.
In addition to the engine itself, a semi-truck also requires other types of lubricants throughout its various components. This includes gear oils for transmissions, axle oils for differentials, power steering fluids for power steering systems and brake fluids for braking systems.
Other Factors
When selecting an oil for a semi-truck’s engine, it is important to consider several other factors such as viscosity rating and API rating. Viscosity ratings measure how thick or thin the oil is while API ratings measure its ability to protect against wear and tear.
Oil Changes
Like all vehicles, semi-trucks need regular maintenance including regular oil changes. How often these changes need to occur depends on the manufacturer’s recommendation as well as how much the truck is used. Typically these changes should be done every 5,000 miles or 6 months.
Conclusion: What Kind of Oil Does a Semi Truck Use?
Heavy duty diesel engine oil, along with additional lubricants depending on climate and age of vehicle, is generally what kind of oil that should be used in a Semi Truck’s engine. It’s important to consider factors such as viscosity rating and API rating when selecting an appropriate motor oil for your truck. Additionally regular maintenance such as regular oil changes should be done every 5,000 miles or 6 months.
