The Ultimate Buying Guide: Choosing Your Diesel Car in the USA
Diesel cars offer great power and fuel economy. They are a smart choice for many drivers in the USA. This guide helps you pick the right one.
Key Features to Look For
When you shop for a diesel car, check these important things first:
- Fuel Economy (MPG): Diesels usually get better miles per gallon than gasoline cars. Look for higher highway MPG numbers.
- Towing Capacity: If you pull trailers or boats, check the maximum weight the diesel engine can handle. Diesel engines have lots of low-end torque, making towing easier.
- Emissions Controls: Modern diesels use complex systems like Diesel Particulate Filters (DPF) and Selective Catalytic Reduction (SCR, which uses Diesel Exhaust Fluid or DEF). These systems reduce pollution but need regular maintenance.
- Engine Size and Type: Bigger trucks usually have larger V8 or inline-six engines. Smaller SUVs might use four-cylinder diesels. Match the engine size to your driving needs.
Important Materials and Build Quality
The quality of materials affects how long your diesel lasts.
- Engine Block and Components: High-quality steel and aluminum parts help the engine handle the higher compression ratios of a diesel. Stronger materials mean better durability.
- Exhaust System: Because of the heat and the added emissions equipment (like the DPF), the exhaust system must be made of corrosion-resistant stainless steel. Cheap components rust fast.
- Interior Materials: Look at the seats and dashboard. Hard plastics wear out quickly. Soft-touch materials offer a better feel and last longer, improving your daily experience.
Factors That Improve or Reduce Quality
What makes a diesel great, and what can cause problems?
Factors That Improve Quality:
- Maintenance Records: A car with complete service history, especially oil changes using the correct diesel-specific oil, is usually a high-quality buy.
- Proper Warm-up: Drivers who let the engine warm up gently before pushing it hard keep the engine healthy.
- DEF System Health: If the DEF tank and injector are working correctly, the emissions system runs smoothly.
Factors That Reduce Quality:
- Short Trips Only: Diesel engines need to get hot to clean the DPF. If a car only drives short distances, the DPF can clog. This is a costly repair.
- Using Wrong Fuel or Oil: Putting gasoline in a diesel tank, or using standard gasoline engine oil instead of required diesel oil, severely damages the engine.
- Ignoring Warning Lights: If the Check Engine Light or the DEF warning light comes on, do not ignore it. Repairs get more expensive the longer they wait.
User Experience and Use Cases
Think about how you will use the car every day.
For the Commuter:
If you drive mostly on the highway for work, a mid-size diesel SUV or sedan offers fantastic fuel savings. You will stop for gas less often. The quiet cabin experience is a big plus on long drives.
For the Hauler/Towner:
Heavy-duty diesel pickup trucks shine here. They manage large RVs or work trailers easily. The torque lets you climb hills without straining the engine. These trucks are built tough for demanding jobs.
For the Off-Roader/Adventurer:
Diesel engines perform well at altitude. If you drive in mountains often, you will notice the power stays consistent where gasoline engines might struggle. Ensure the vehicle has good ground clearance and 4×4 capability.
10 Frequently Asked Questions (FAQ) About Diesel Cars in the USA
Q: Are diesel cars still sold new in the USA?
A: Yes, some automakers still sell new diesel trucks and SUVs, though the selection is smaller than in the past. Many popular models are now discontinued.
Q: Is diesel fuel more expensive than gasoline?
A: Fuel prices change often. Sometimes diesel costs more, sometimes less, depending on the region and time of year. You must compare the cost per gallon versus the better MPG you get.
Q: Do diesel engines last longer than gasoline engines?
A: Generally, yes. Diesel engines are built stronger to handle higher compression. With good maintenance, many diesels easily reach 300,000 miles or more.
Q: What is DEF, and why do I need it?
A: DEF stands for Diesel Exhaust Fluid. It is a liquid injected into the exhaust system to turn harmful nitrogen oxides into harmless nitrogen and water vapor, keeping the air cleaner.
Q: What happens if my DPF gets clogged?
A: A clogged DPF reduces engine power and can cause the car to enter “limp mode.” If you cannot drive it long enough to perform a regeneration (cleaning burn), a mechanic must clean or replace the filter, which costs a lot of money.
Q: Are older diesel cars okay to buy used?
A: Older diesels (pre-2007) do not have complex emissions systems, which some buyers like. However, they lack the fuel efficiency improvements of newer models.
Q: Is diesel maintenance harder than gasoline maintenance?
A: Maintenance is similar, but you must use the correct, often more expensive, diesel engine oil. Also, monitoring the DEF level is an extra step.
Q: Can I use biodiesel (B20) in my modern diesel car?
A: Check your owner’s manual. Many modern diesels can handle B20 (20% biodiesel blend), but some manufacturers recommend sticking to pure petroleum diesel for warranty reasons.
Q: Do diesel cars smell bad?
A: Modern, well-maintained diesels running on good fuel have very little odor when driving. Older models or those with faulty emissions systems might produce noticeable soot or smell.
Q: Is it hard to start a diesel in the cold?
A: Modern diesels use glow plugs to heat the cylinders for easy starting, even when it is very cold. You usually do not have issues unless the battery is weak or the glow plugs fail.
