Have you ever wondered if driving a diesel-powered vehicle is actually right for you? The answer depends on several factors. While we all love them here, we also understand that they may not be right for everyone. Diesel engines can offer specific benefits but also have some drawbacks depending on your driving habits and needs. Here’s a breakdown of the key factors to consider:
1. Driving Habits
- Long-distance driving: Diesel engines are often more efficient than gasoline engines on long trips. They provide better fuel economy at higher speeds, which could make them a good choice if you are driving long distances. If you are someone who commutes a fair distance every day, you will likely get the most out of owning and driving a diesel.
- Frequent short trips: Diesel engines take longer to reach their optimal operating temperature, so if you mostly do short trips around town, the engine may not be as efficient, and you might experience lower fuel economy, higher emissions, and soot and carbon buildup over time.
2. Fuel Economy
- Efficiency: Diesel engines generally offer better miles per gallon (MPG) than gasoline engines, especially with highway driving. This is a key selling point for people who want to save on fuel costs over the long term. Some diesel-powered vehicles get almost double the fuel efficiency of their gas-engine counterparts.
- Fuel costs: Diesel fuel is often more expensive than gasoline in some areas, though this depends on local fuel prices. The price difference can sometimes offset the better fuel economy, so you’ll want to consider how it balances out for your driving patterns.
3. Towing and Payload Needs
- Heavy-duty performance: Diesel engines tend to have more torque than gasoline engines, which is a significant advantage if you plan to tow heavy loads or haul a lot of cargo. Obviously, the real limiting factor is the payload limit of your vehicle, but having a diesel engine behind that payload makes all the difference. Trucks and larger vehicles that need to handle these tasks often have diesel engine options for that reason.
4. Environmental Considerations
- Emissions: Diesel engines produce more nitrogen oxide (NOx) and particulate matter than gasoline engines, which contributes to air pollution. However, modern diesel engines with advanced emissions technologies (like DEF systems and particulate filters) have made significant improvements. That said, they are still typically less eco-friendly than hybrids or electric vehicles.
- Regulations: Diesel vehicles may be subject to stricter emissions regulations in some cities, and there could be increasing restrictions on older diesel models in the future as air quality standards tighten.
5. Maintenance and Durability
- Long lifespan: Diesel engines are known for their longevity. They tend to last longer than gasoline engines, especially if maintained properly. We have plenty of customers with vehicles over 400k miles now that are still trucking along with basic maintenance. However, diesel maintenance can be more expensive, and the parts may require more frequent attention (e.g., diesel particulate filter maintenance).
- Cost of repairs: Diesel engines are typically more expensive to repair than gasoline engines, especially if something goes wrong with the fuel system, turbochargers, or emissions components. If you’re in an area with limited diesel mechanics or parts, that could add to the inconvenience. One thing in key to look out for is the cost of replacing emissions equipment, as some diesel cars require Diesel Particulate Filters, or DPF’s, that can cost a few thousand dollars if in need of replacement.

6. Resale Value
- Diesel vehicles can have a strong resale value, especially for larger trucks or SUVs with diesel engines, as buyers may value the durability and towing capabilities. However, this can vary by market, as interest in diesel engines has fluctuated with the rise of hybrids and electric vehicles. That being said, we still see diesel-powered variants of some vehicles selling for up to 20% higher than their gasoline counterparts.
7. Upfront Cost
- Diesel vehicles generally cost more upfront than their gasoline counterparts due to the complexity of the engine and the additional emissions control technologies.
Conclusion:
If your primary need is excellent fuel economy, long-distance driving, and heavy-duty towing or hauling, a diesel vehicle might be a good fit. However, if your driving is mostly in the city or consists of shorter trips, a gasoline-powered vehicle may be a better choice.
