How Many Miles Do Semi Trucks Last?

If you are in the market to purchase a semi truck, you have likely asked yourself the question: how many miles do semi trucks last? It’s an important and valid question — after all, semi trucks aren’t cheap and you want to make sure your investment will hold up over time.

In this blog post, we’ll dive into the specifics of how long these vehicles usually last so that as you search for your perfect ride, you know what kind of mileage expectation is typical.

Average Lifespan of Semi Trucks

In fact, the average lifespan of a semi truck is around 750,000 miles or more. That’s a significant difference compared to the 200,000 miles that the average car can handle. With semi trucks driving an average of 45,000 miles per year, it’s possible to enjoy up to 15 years of reliable use from your rig. And, if you take good care of it, you might even hit that one million mile mark!

Highest Truck Mileage Record

Are you a trucker in search of the highest mileage record? Look no further than William Coe, Jr. from Tallahassee, Florida. Coe’s impressive feat of safely driving his semi truck for 3,001,276 miles earned him the world record in 2009. That’s over 120 times around the Earth! Coe began his trucking journey in 1986 and has been on the road ever since.

What Makes Semi-Trucks So Durable?

One of the key reasons why these behemoths can withstand the rigors of long hauls and rough terrain is their diesel engine design.

Unlike gasoline engines, diesel engines run at lower RPMs and are built to withstand higher levels of compression, which translates to less wear and tear over time.

Additionally, diesel engines come equipped with specialized parts and mechanics that prevent engine failure, making them a popular choice for professional drivers looking for a reliable and long-lasting truck.


How to Get the Most Mileage Out of Your Semi Truck

While semi trucks are built to last, they still require the proper care and maintenance in order to get the most out of their mileage. Here are some tips and tricks on how to achieve that:

Get Your Oil Changed Regularly

One of the most essential ways to prolong the life of your truck is by changing the oil consistently. Whether you’re putting in many miles or only a few, it’s recommended that you change your oil annually or every 7,500 to 10,000 miles. Don’t overlook this simple yet crucial step in truck maintenance. Set a reminder for yourself and check the oil levels before each trip. Neglecting necessary oil changes can lead to premature wear and damage.

Get Your Brakes Inspected

Brake failure is a dangerous situation that no one wants to experience, so it’s crucial to pay attention to any squealing or vibrations you might feel while driving. By inspecting your brakes before each long trip, you can avoid any unexpected breakdowns and keep your truck running smoothly for longer.

Get Your Radiator Inspected

One component that you cannot neglect is your radiator. Your radiator is responsible for regulating the temperature of your engine, and if it’s not functioning properly, it can lead to major problems. Don’t let a faulty radiator leave you stranded on the side of the road.

Take the time to get it inspected regularly so that you can identify any issues before they become serious. With proper care and maintenance, your radiator will keep your semi-truck running smoothly for years to come.

Check for Blockages in Your Fuel Vent

Blockages in your fuel vent are one issue that cannot be overlooked, as they can cause serious problems for both your engine and your wallet. In addition to affecting engine performance and longevity, a blocked fuel vent can also lead to inaccurate fuel readings, affecting your ability to manage your fuel costs effectively.

To avoid these issues, it’s essential to check your fuel vent regularly, especially after your truck has sat in one place for a period of time.

Keep Moving Parts Greased

Do you want your semi-truck to last longer with less maintenance required? Of course you do! One way to achieve this is to regularly grease all of the moving parts in your engine. While it may take some time, this is something that you can easily do yourself without the help of a mechanic.

By taking the time to keep your moving parts greased, you’re ensuring that your engine is running smoothly and efficiently, saving you time and money in the long run.


Factors That Decrease Semi-Truck Lifespan

The type of trailer it pulls

Wear and tear on semi-trucks can be accelerated based on the types of loads they haul. Heavier loads can put a strain on the vehicle and its components, ultimately leading to more maintenance costs and potential damage over time.

Driving conditions

As a buyer, you want to make sure that the semi-truck you invest in will last you for years to come. However, road conditions and weather can have a big impact on the lifespan of your vehicle. Poorly paved roads or extreme weather conditions can cause wear and tear on your semi-truck much faster than normal driving conditions.

Fuel quality

Choosing a lower quality fuel can ultimately decrease your truck’s lifespan, causing unwelcome engine wear and corrosion. Not only that, but it may also contribute to higher air pollutant emissions, putting you at risk of compliance violations.

Idle time

Allowing your truck to idle excessively can lead to decreased efficiency, expensive repairs, and wear and tear on vital engine components. Furthermore, leaving your truck dormant for too long can have detrimental effects, such as rust and outdated parts.

Driving habits

Drivers who do not take adequate rest breaks, overfill the truck with cargo, and speed often put undue stress on the engine and other parts of the truck. This can result in costly repairs and even shorten the life of the truck.
