Is it Okay to Buy a Used Diesel Truck with 200,000 Miles?

When considering the purchase of a used diesel truck, one of the most common concerns is how far the vehicle has already traveled. Diesel highway tractors used to log impressive mileage, often reaching 2 million miles, but more modern models are seeing significantly lower figures due to advancements in emissions management systems.

Understanding Diesel Truck Mileage

Diesel engines like those in highway tractors are designed to be rugged and durable. However, the rollback of emissions management systems in some cases has led to a drop in expected lifespan, with many modern trucks logging around 300,000 miles before requiring significant maintenance. Some truckers suggest that certain engines, especially older ones with no emissions controls, can reach upwards of 2 million miles with proper maintenance.

Key Factors in Choosing a Used Diesel Truck

When purchasing a used diesel truck, several factors should be considered to ensure you get a reliable vehicle. These include:

Mileage and Condition: The truck's overall condition is crucial. Even if the odometer reads 200,000 miles, the actual condition of the truck is what matters most. Look for signs of rust, wear, or other issues that might indicate poor maintenance. Maintenance Schedule: Religious oil changes and regular maintenance can significantly extend the life of a diesel engine. Ensure the truck has a consistent maintenance history. Expert Inspection: Consider hiring a professional for an inspection. They can identify potential issues that might not be immediately visible to the naked eye. Pricing: The mileage should not be the sole determining factor. If the truck is a great deal, don't let the high mileage deter you. Conversely, if the seller is asking a premium price, look for something with less mileage for the same budget.

Real-Life Examples of Successful Used Diesel Truck Buys

Here are a couple of real-life examples of successful diesel truck purchases:

Example 1: Freightliner with 216,000 Miles

A Freightliner truck with 216,000 miles was purchased in 2000 and looked nearly new. The truck has been very reliable, demonstrating that with proper care and maintenance, a diesel truck can last a long time. The owner maintains that regular oil changes are key to longevity.

Example 2: 1996 Powerstroke with 278,000 Miles

The author bought a 1996 Powerstroke with 278,000 miles in 2016. While some parts needed to be replaced over the years, the truck remains functional and reliable. The low price ($2,700) ensured that any repairs were within budget. The lesson here is that a good deal can make up for high mileage.

Example 3: 1985 Kenworth with 445,000 Miles

The author also owns a 1985 Kenworth with 445,000 miles and has converted it into a motorhome. This example shows that with proper maintenance and conversion, a truck with a high mileage can still serve a niche purpose well.

Conclusion

While 200,000 miles in a diesel truck is a significant number, it is not necessarily a deal-breaker. The key is to ensure the truck has been well-maintained. Buyers should do their due diligence and, if necessary, hire an expert to inspect the vehicle. Proper maintenance and a thorough inspection can ensure that the truck continues to serve as a reliable and efficient means of transportation for years to come.
