What are the advantages of a diesel engine?
Diesels get great mileage. They typically deliver 25 to 30 percent better fuel economy than similarly performing gasoline engines. Diesel fuel is one of the most efficient and energy dense fuels available today. Because it contains more usable energy than gasoline, it delivers better fuel economy.
Is a diesel engine worth it?
Diesel engines are still more efficient than gas engines, but less so for those who are mostly engaged in city driving. Diesel cars also have more torque, which results in better fuel economy along with more impressive acceleration. … For most U.S. consumers, diesel fuel and gas fuel cost about the same.
What are two advantages of a diesel engine?

- Excellent gas mileage.
- Longer range. Better fuel economy means you don’t have to hit the gas station as often. …
- Diesels have no spark plugs or distributors, so they never need ignition tune-ups.
- Better durability. …
- More torque.
What are the problems with diesel engines?
These are eight of the most common diesel problems:
- Difficult start. As a diesel owner, you know that they may crank a bit when started. …
- Lack of power. …
- Contaminated fuel. …
- Faulty lead/acid storage battery. …
- Black exhaust. …
- Oil oxidation. …
- Incorrect weight viscosity. …
- An overabundance of noise.
Which is better Duramax or Cummins?
More horsepower means faster acceleration whether you’re towing or not. The current Duramax 6.6L L5P diesel wins this category with 445 horsepower. The current 6.7L 24V Ram Cummins diesel engines produce 400 horsepower. Historically, horsepower has swayed slightly in favor of the Duramax versus the Cummins line.
Why does a diesel knock?
Knocking is more or less unavoidable in diesel engines, where fuel is injected into highly compressed air towards the end of the compression stroke. … This sudden increase in pressure and temperature causes the distinctive diesel ‘knock’ or ‘clatter’, some of which must be allowed for in the engine design.
Why do diesels last longer?
A diesel engine will also last much longer than its gasoline counterpart. … “That’s because diesel is a very light oil, and when you burn diesel in an internal combustion engine you’re basically lubricating the valves, rings, and piston walls.
Do diesel cars need to be driven regularly?
Diesels fitted with a Diesel Particulate Filter (DPF) need regular long runs, some of which must be at high engine speed to clean (regenerate) the filter so are not suited to mostly short, local journeys.
Why you shouldn’t buy a diesel?
On the downside, however, despite the cleaner emissions that catalytic converters can provide, diesel cars still pollute the air, particularly when accelerating from a complete stop. Some of the particulates in the emissions of these cars include carcinogens, soot and nitrous oxide.
Are diesels expensive to maintain?
Diesel maintenance is cheaper overall, since diesel engines have fewer problems than gas engines; but diesels are more expensive when they need repairs. Diesel maintenance generally will not cost you more than for a gasoline powered version, depending upon the type of diesel car that you have.
How long will diesel trucks last?
A gasoline powered truck can run for 200,000 miles. Conversely, a diesel truck has a longer lifespan and can run for at least 500,000 and as much as 800,000 miles. This is because it has a heavier and sturdier body.
Why should I buy a diesel pickup?
Not only can diesels haul heavier loads, but they can also do it more efficiently, saving on fuel. That’s why they’re the perfect trucks for work-related or recreational use. They can handle tough challenges on the job, and they can also tow sport vehicles, trailers, or campers without hesitation.
Why is a diesel engine better for towing?
Most truck enthusiasts will tell you the diesel is better than its gasoline counterpart when it comes to towing. The engines get better gas mileage, last longer and usually can tow more. Diesel Engines have a lot of low-end torque and can pull heavy loads up extreme grades with confidence.
