The Ultimate Buying Guide for Diesel Cars in the USA
Diesel cars offer great fuel economy and strong pulling power. Buying one in the USA requires knowing a few key things. This guide helps you choose the right diesel vehicle for your needs.
Key Features to Look For
When shopping for a diesel car or truck, certain features really matter. These features affect how long your vehicle lasts and how much it costs to run.
Engine Technology
- Modern Emissions Systems: Look for vehicles with Diesel Particulate Filters (DPF) and Selective Catalytic Reduction (SCR, which uses Diesel Exhaust Fluid or DEF). These keep the air cleaner. Older diesels might struggle with new city rules.
- Turbocharging: Almost all modern diesels use turbochargers. They help the engine breathe better and make more power, especially when pulling heavy loads.
- Glow Plugs: These help the engine start in cold weather. Good glow plugs mean easier starts on chilly mornings.
Towing and Torque
The main reason people buy diesels is torque—that pulling muscle. Check the torque rating (measured in pound-feet). Higher torque means easier towing and hauling.
Important Materials and Build Quality
The quality of materials impacts reliability. Diesel engines work harder than gasoline engines, so they need strong parts.
Engine Internals
Look for strong components. Modern diesel blocks are usually made of strong cast iron or aluminum alloys. Check reviews to see if the fuel injectors and high-pressure fuel pump are known to be reliable. These parts are expensive to fix.
Frame and Body
If you are buying a truck, the frame needs to be tough. Heavy-duty diesels often have fully boxed, high-strength steel frames. This protects the vehicle when you carry heavy weight.
Factors That Improve or Reduce Quality
What you do with the car matters as much as what it is made of.
Factors That Improve Quality (Longevity)
- Regular Oil Changes: Diesel oil gets dirty faster because of soot. Follow the manufacturer’s schedule strictly. Use the correct type of oil.
- Proper Warm-up/Cool-down: Let the engine run for a minute before driving hard, especially when it is cold. This protects the turbocharger.
- DEF Maintenance: If the vehicle uses DEF, keep the tank filled. Running out can cause the engine to enter “limp mode,” which reduces power.
Factors That Reduce Quality (Potential Problems)
The biggest quality reducers often involve the emissions systems. If you only drive very short distances at low speeds, the DPF might not get hot enough to clean itself (regenerate). This can cause expensive clogging.
Also, poor fuel quality hurts diesel engines quickly. Always try to buy fuel from busy stations, as fresh fuel is better for the sensitive injection system.
User Experience and Use Cases
How you plan to use your diesel vehicle heavily influences your choice.
The Commuter Experience
If you drive mostly in the city, a smaller diesel car (like an older VW Jetta TDI or a newer small SUV) offers fantastic mileage. Be careful about city-only driving reducing the life of the DPF, as noted above.
The Hauler/Towing Experience
For heavy towing (boats, RVs, construction gear), a heavy-duty pickup truck is necessary. These diesels provide the low-end grunt needed to pull steep grades without straining. The driving experience feels solid and powerful.
Fuel Availability
Diesel fuel is widely available at large gas stations across the USA. However, in very remote areas, it might be harder to find high-quality diesel, especially in winter (where special winter-blend fuel is needed to prevent gelling).
Frequently Asked Questions (FAQ) About Buying Diesel Cars in the USA
Q: Are diesel cars more expensive than gasoline cars?
A: Yes, typically the initial purchase price is higher. However, they often save money over time because diesel fuel is often cheaper than premium gasoline, and the cars get much better miles per gallon (MPG).
Q: Do I need to worry about emissions testing if I buy a diesel?
A: It depends on where you live. States like California have very strict testing for diesel vehicles. Newer diesels with DPF systems usually pass easily, but older models might fail smog checks.
Q: What is DEF, and do all new diesels use it?
A: DEF stands for Diesel Exhaust Fluid. It is a non-toxic liquid sprayed into the exhaust to clean up harmful nitrogen oxides. Most modern light-duty and heavy-duty diesels made after 2010 use DEF.
Q: How long do modern diesel engines usually last?
A: If maintained well, modern diesel engines often last much longer than gasoline engines. It is common for well-cared-for diesels to easily reach 300,000 miles or more.
Q: Is diesel maintenance much harder or more expensive?
A: Maintenance is more frequent, especially oil changes. Parts like fuel injectors and the DPF system can be expensive to replace if they fail. Simple maintenance is easy, but complex repairs cost more.
Q: What should I look for when buying a used diesel truck?
A: Check the maintenance records carefully. Ask specifically about the transmission fluid and if the DPF has ever been cleaned or replaced. Always have a mechanic inspect the fuel injection system.
Q: Can I drive a diesel car in very cold weather?
A: Yes, but you must use winterized diesel fuel in freezing temperatures. This fuel has additives that stop the diesel from turning into a waxy gel, which stops the fuel lines from clogging.
Q: Do diesel cars perform poorly in the city?
A: They can. Short trips prevent the engine and the DPF from reaching high enough temperatures to clean themselves. This leads to soot buildup and possible check engine lights.
Q: Is diesel fuel always cheaper than regular gasoline?
A: Not always. Fuel prices change daily. You must calculate the MPG difference. Even if diesel costs the same per gallon, the higher MPG usually makes the diesel cheaper to drive overall.
Q: What is “delete kits” in the diesel world?
A: “Delete kits” remove the DPF and EGR (Exhaust Gas Recirculation) systems. While this can simplify maintenance, it is illegal for on-road use in the USA and will cause the vehicle to fail emissions testing.
