The biggest difference between diesel and gas truck maintenance is frequency and cost. Gas trucks require smaller, more frequent services, while diesel trucks need less frequent but more specialized care.
At Archie & Sons Diesel Repair, we work exclusively on diesel trucks, and we’re here to help North Carolina owners understand the unique care they need. Diesel engines are built for heavy-duty towing and longevity, but they carry higher per-visit costs due to their complexity.
In this guide, we’ll cover:
- Service schedules for diesel vs. gas trucks
- Maintenance costs per visit and over time
- Longevity and reliability differences
- Performance impacts on towing and driving
- The importance of choosing the right shop
By the end, you’ll know the key differences in care and why trusting a specialized shop like Archie & Sons Diesel Repair makes all the difference.
Engine Basics: How Diesel and Gas Power Your Truck
Diesel and gas engines share the same purpose but work in very different ways.
- Ignition System: Diesel engines use compression ignition, while gas engines depend on spark plugs.
- Fuel Type: Diesel fuel is denser and energy-rich, providing torque for heavy-duty work. Gasoline burns cleaner and is better for light driving.
- Durability: Diesel engines are designed to last longer and handle higher stress levels.
- Application: Gas trucks are practical for daily commuting and moderate hauling, while diesels shine in commercial use and towing.
These engineering differences explain why diesel service requires specialized knowledge.
Gas Truck Maintenance Basics
Gas trucks remain popular for affordability and ease of service. Here are the essentials:
Oil and Filter Changes
Gas engines need oil changes more frequently, typically every 3,000–5,000 miles. Consistent filter changes help prevent buildup and extend engine life.
Spark Plug Replacement
Since gas engines rely on spark ignition, spark plugs eventually wear out and must be replaced between 30,000 and 100,000 miles.
Cooling System Service
Gas engines tend to run hotter, so coolant flushes and radiator inspections are critical to prevent overheating.
Fuel System Care
Gasoline burns cleaner than diesel fuel, but injectors and filters still require periodic cleaning to maintain fuel economy.
Tip: For drivers who want predictable, lower short-term service costs, gas trucks are a practical choice.
Diesel Truck Maintenance Basics
Diesel trucks are workhorses designed for endurance and power. Their service requirements reflect that strength.
Oil and Filters
Diesels go longer between oil changes (7,500 miles or more) but require significantly more oil. That means higher costs per visit, though less frequent service overall.
Fuel System Maintenance
Diesel fuel is heavier and contains impurities, so fuel filters need to be replaced more often, typically every 10,000–15,000 miles. Water separators also require regular inspection.
Glow Plugs
Instead of spark plugs, diesel engines use glow plugs for cold starts. They last longer but will eventually need replacement.
Turbo and Exhaust Systems
Many diesel trucks are turbocharged. Protecting the turbo requires clean oil and proper maintenance. In addition, diesel particulate filters (DPFs) must be cleaned or replaced to keep emissions systems functioning.
Cooling System Care
Diesel engines run at higher compression levels. Their radiators, hoses, and water pumps need more frequent inspections to handle the added stress.
Tip: Regular service is critical for diesel trucks, especially for business owners who cannot afford downtime.
Diesel vs. Gas: A Clear Truck Maintenance Comparison
| Aspect | Gas Truck | Diesel Truck |
|---|---|---|
| Oil Changes | 3,000–5,000 miles, smaller capacity | 7,500+ miles, higher capacity |
| Ignition Components | Spark plugs, replaced periodically | Glow plugs, longer lifespan |
| Fuel System | Moderate service needs | Frequent filter changes, water separation |
| Cooling | Needs attention due to heat | Designed for high compression |
| Service Costs | Lower per visit, higher frequency | Higher per visit, less frequent |
| Longevity | Shorter average lifespan | 300,000+ miles with proper care |
| Best Fit | Everyday driving, light towing | Heavy towing, commercial work |
What Happens If You Skip Maintenance
Risks for Gas Trucks
- Overheating from neglected cooling systems
- Poor performance from worn spark plugs
- Reduced fuel efficiency with dirty injectors
Risks for Diesel Trucks
- Injector or turbocharger failure from dirty fuel or poor oil quality
- Clogged DPFs leading to power loss and expensive replacements
- Cooling system breakdowns causing major engine damage
In both cases, skipped maintenance shortens your truck’s life and increases repair costs.
Choosing Between Diesel and Gas Trucks
For many truck owners, the decision comes down to intended use.
- Gas Trucks: Great for everyday drivers, weekend haulers, and those wanting lower service costs per visit.
- Diesel Trucks: The best option for towing, hauling, and business owners who depend on their trucks for income.
If you’re a contractor or fleet manager in Goldsboro, NC, investing in regular diesel truck maintenance pays off with durability and reduced downtime.

Frequently Asked Questions
Is diesel truck maintenance more expensive than gas?
Yes, diesel truck maintenance is usually more expensive than gas because of larger oil capacities, more frequent fuel filter changes, and specialized parts. However, diesels often need service less often and provide better long-term value for heavy-duty use.
How often do diesel trucks need oil changes?
Most diesel trucks need oil changes every 7,500 miles, though this depends on driving conditions and manufacturer guidelines. Heavy towing or frequent city driving may shorten the interval, while highway driving can sometimes extend it.
Do diesel trucks last longer than gas trucks?
Yes, diesel trucks usually last longer than gas trucks, often exceeding 300,000 miles with proper care. Stronger components and high-compression design give them durability, especially for towing and hauling.
What are the disadvantages of a diesel truck?
The main disadvantages of a diesel truck are higher upfront costs, pricier repairs, and complex emissions systems like diesel particulate filters (DPFs). Fuel can also cost more, but many drivers find the torque and longevity outweigh these drawbacks.
Is a diesel truck better for towing than gas?
Yes, diesel trucks are better for towing than gas trucks because they produce more torque at lower RPMs, making heavy loads easier to pull. Gas trucks can tow smaller trailers, but diesels are the top choice for frequent or long-distance hauling.
