How Often Should You Change Your Semi Truck Oil?

Commercial vehicles adhere to different oil change frequencies compared to consumer vehicles. While a typical consumer car might undergo an oil change every 3,000 miles, commercial or semi trucks often wait until they’ve covered 25,000 miles. Despite the seemingly extended interval, a semi truck is likely to achieve 25,000 miles much sooner than a regular car hits 3,000 miles. The determination of oil change frequency in semi trucks involves various factors.

Maintaining a semi truck involves a series of crucial tasks, and one of the most fundamental aspects is the regular oil change. Unlike consumer vehicles, semi trucks have unique oil change requirements dictated by various factors. In this article, we’ll explore how often a semi truck requires an oil change and the factors that influence this frequency.

Factors Influencing Semi Truck Oil Change Frequency:

Efficient Driving Habits:

Driving efficiently at constant speeds on highways can significantly impact the oil change frequency. Efficient driving reduces the wear and tear on the engine, resulting in a longer interval between oil changes.

Routine Maintenance:

Regular maintenance of the truck’s engine is essential for extending the life of the oil. Following a routine maintenance schedule, including inspections and necessary repairs, can contribute to less frequent oil changes.

Type of Oil Used:

The quality of the oil used plays a crucial role in determining the change frequency. Higher quality oils may offer better longevity, allowing for extended periods between oil changes.

Driving Conditions:

External factors such as road quality, climate variations, and environmental pollution can impact how often a semi truck needs an oil change. Poor road conditions, travel through diverse climates, or exposure to high levels of pollution may necessitate more frequent oil changes.

Recommended Oil Change Interval for Semi Trucks:

  • In general, it is advisable to change the oil in a semi truck every 25,000 miles.
  • Some circumstances may warrant more frequent changes, possibly every 13,000 miles.

Tips to Extend Oil Life in Semi Trucks:

Use Higher Quality Oil:

Opt for high-quality oils designed for commercial vehicles to ensure better performance and durability.

Drive Efficiently:

Adopt efficient driving habits to minimize stress on the engine and reduce the need for frequent oil changes.

Regular Engine Testing:

Periodic testing of the engine’s condition can help identify issues early, preventing excessive wear on the oil.

Routine Maintenance:

Adhering to a regular maintenance schedule, including oil filter replacement and fluid checks, is crucial for overall engine health.

What Determins Semi Truck Oil Change Frequency?

Efficient driving, especially at constant speeds on highways, reduces the need for frequent oil changes. Regular maintenance of the truck engine contributes to prolonging the life of the oil. External elements like road quality, climate variations, and environmental pollution also influence oil change frequency. If you navigate through poor-quality roads, experience diverse climate zones, or drive in areas with high air and ground pollution, you may need more frequent oil changes.

How Often Should You Change Your Semi Truck’s Oil?

As a general guideline, it’s recommended to change the oil in a semi truck every 25,000 miles. However, individual circumstances may necessitate more frequent changes, possibly every 13,000 miles. To extend the life of the oil, consider using higher quality oil, driving efficiently, testing the engine, and performing regular maintenance.

How Much Does a Semi Truck Oil Change Cost?

The cost of a semi truck oil change can vary widely based on factors such as the type of oil used, the quantity required, the filter selected, and labor costs. While there is no universally recognized average cost, you can obtain a quote for a semi truck oil change by providing details about your specific situation.


Understanding the factors influencing the frequency of oil changes for semi trucks is essential for maintaining optimal engine performance and longevity. By adopting efficient driving practices, prioritizing routine maintenance, and using high-quality oil, truck owners can strike a balance between cost-effectiveness and engine health. Regular monitoring and adherence to manufacturer recommendations will contribute to a smoothly running semi truck with fewer unplanned maintenance issues.
