Do Diesel Cars Need To Be Driven Regularly?

Every motorist is enthralled by the prospect. If this question had been posed years ago, the response would have been a resounding yes, if not a resounding yes. The situation has now altered. Let’s have a look at what has changed in the last few years.

Development Of CRDI Engines

There is no need to run diesel cars on a daily basis since the development of CRDI engines. Previously, the problem would arise while starting a cold engine. It used to take a long time for the engine to warm up the fuel. The time it took to heat up the fuel sucked up a lot of electricity, making it difficult for diesel cars to start on time. With the introduction of CRDI engines, there is no longer any need to drive diesel cars on a daily basis. The acronym CRDI stands for Common Rail Direct Injection. This enables direct fuel injection into the engine via a single common line. This is why you don’t need to drive your diesel car on a regular basis any longer. No one will ask if diesel automobiles need to be driven on a daily basis any longer.

Rigid Steel Lines

Diesel cars were a problem in those days. At the time, fuel lines were prone to air entrainment, which rendered the car stationary. If the cars were not driven for more than ten days, they would simply stop or provide any imaginable mistake while attempting to start them. These days, diesel cars have a more robust steel line, which means that no matter how long it sits in the garage, it will never stop.

Daily Ignition Is Not Needed

Vehicles and their engines have evolved dramatically in recent years. There was a time when daily ignition was required to keep the car in good working order. There is now very little work that has to be done on the car. Even specialists agree that this is one of the most common misunderstandings that has to be dispelled right now. Modern diesel automobiles do not necessitate continuous attention. Use it as needed and store it in the garage when not in use. Allow your vehicle to enjoy parking mode, and it will not be harmed, contrary to popular belief. There’s no way it’ll get stuck! Just bear in mind some expert maintenance advice that you might get online.

How often should I drive my diesel car?

The easiest approach to keep a DPF in good working order is to make sure it can regenerate itself when it’s full of soot (when the warning light appears).

Passive regeneration

Passive regeneration happens when the car is traveling at a high speed on a long highway drive, allowing the exhaust temperature to rise to a greater level, allowing the excess soot in the filter to be burned off cleanly.

To help clear the filter, drivers should give their diesel vehicle a solid 30 to 50 minute run at sustained speed on a highway or A-road on a frequent basis.

However, not all drivers engage in this type of driving on a regular basis, which is why automakers have devised a different method of regeneration.

Active regeneration

When a filter hits a predetermined limit (usually around 45 percent), more fuel is injected automatically as part of the vehicle’s ECU to boost the temperature of the exhaust and burn off the stored soot.

However, if the journey is too short, problems may arise since the regeneration process may not be completed completely.

In this instance, the warning light will remain illuminated, indicating that the filter is still partially clogged.

In that instance, completing a regeneration cycle and clearing the warning signal should be doable by driving for 10 minutes or more at speeds greater than 40mph.

The following signs will indicate whether active regeneration is occurring:

What happens if you don’t drive a diesel car often?

A diesel particulate filter has been standard on diesel cars since around 2008 (and sometimes earlier) (DPF). This device catches the black soot particles that older diesel engines emit, particularly when they are cold. The DPF holds the soot until the filter unit reaches a specified temperature, at which point the soot is burned off. It still reaches the atmosphere, but as finer, invisible particles rather than the obnoxious black smoke, and poses a lower health risk (allegedly, but this is disputed).

The engine must have been running for at least 15-20 minutes to get the filter trap hot enough to burn off the soot, and it takes another 10-15 minutes to burn the soot and clean the filter.

When DPFs were originally introduced into the automotive sector, most individuals – including car dealers – were unaware of their existence, and customers were unaware they even had one. The filter trap clogs up if the driver does not go for a drive of at least half an hour on a regular basis (i.e. once a week to once a fortnight). In addition to failing to efficiently filter diesel soot, continuous or repeated blockage will eventually ruin the filter, necessitating a costly replacement.

So, if you don’t drive your car on a regular basis for 20-30 minutes, you’ll have to make a special journey every week or two to clear your DPF, which won’t help your fuel expenditures.

Better-designed DPFs and improved engine computer controls in cars built since about 2012-ish usually allow for faster and more efficient burning off of the soot, so it’s less of a problem now than it was before, but it’s still a problem for dealers who have to deal with irate customers who object to paying hundreds of pounds to replace their DPF when they weren’t made aware of it.

This is an even bigger problem for used automobile buyers, who are more likely to get into difficulty because they were almost certainly not given a sufficient explanation by the dealer.

Do diesel cars require daily running?

No, the Morden Crdi technology diesel engine does not need to be run on a daily basis; instead, it can be used after 15 days of perfect performance, much like a petrol engine. Only if you drive 1500 kilometers per month does a diesel car make sense.

Do diesel engine cars need to be driven regularly?

This is the most typical misunderstanding. Modern diesel vehicles do not necessitate continual maintenance. You can use it whenever you want. Otherwise, you can park it safely without fear of the pieces jamming.

It used to be a given that diesel cars required to be run more frequently than gasoline cars. This is no longer the case in modern vehicles, since technology has rendered diesel comparable to gasoline in terms of use.

Can I still drive my diesel car after 2030?

No, the petrol and diesel automobile prohibition only applies to new combustion engine cars; existing cars will continue to be lawful to buy and drive. Because a car’s typical lifespan is 14 years, new petrol and diesel cars purchased in late 2029 might last until at least 2044.

Do short trips hurt diesel engines?

I have a question about diesel-powered vehicles. I’m quite aware that they save gas, especially on longer trips, and that newer models are quiet and have good acceleration. My wife, on the other hand, prefers short drives, usually less than 5 km (shopping, etc. ), which she does in the winter as well. Is a diesel car’s fuel economy and performance equivalent to a car with a gas engine on a short, cold-weather ride when the engine temperature is unlikely to reach optimum? Terry –

If you simply make short excursions to the store, a diesel engine will not save you money on petrol and will, in the long term, cost you more than a gasoline engine.

“I hate to say it, but I don’t think diesel is suited for this gentleman,” says Thomas Tetzlaff of Volkswagen Canada. “They’re quiet, have excellent acceleration, and have excellent fuel efficiency.” However, they were not built to be driven only five kilometers every day.”

Unlike gasoline engines, diesel engines do not utilize spark plugs to ignite the fuel. Fuel is fed into the cylinders at such a high pressure in a diesel engine that the air inside the cylinders heats up and the fuel ignites. This takes a second or two in current cars after turning the key.

Tetzlaff believes diesel engines, especially in the colder months, need to warm up a little after starting to reach their ideal operating temperature — when they’re most fuel-efficient.

“They’re not even going to be remotely heated in a span of five kilometers,” he says. “In the city, a diesel performs admirably. For this motorist, it’s not so much the stop-and-go driving that’s the issue. It’s only that the daily distances are so short.

“It would be fine if there were a bunch of five-kilometer journeys in one day,” Tetzlaff says.

Diesel engines are extremely fuel efficient when they are run for extended periods of time and kept at a constant temperature – they must be hot.

“We’ve had clients go 1,500 kilometers (on one tank) in one trip with a Passat diesel,” Tetzlaff says. “However, if you’re only going to the shop and back, you won’t be able to spend 300 days without filling up.”

Short operating intervals are detrimental to the economy and reliability of a diesel engine, according to Patrick Brown-Harrison, an automotive instructor at SAIT Polytechnic in Calgary. Furthermore, because the engine must warm the coolant before any heat can be transferred to the passenger compartment, diesels have typically taken longer to warm up inside in the cold.

“Some manufacturers add pre-heaters, or you can install an aftermarket one,” Brown-Harrison explains.

For a car that will only be used for short trips across town, Tetzlaff and Brown-Harrison recommend gasoline, a hybrid, or even electric automobiles.

“If you drive 10,000 kilometers a year (approximately 25 kilometers or less per day), you should consider a gasoline-powered automobile or a hybrid,” Tetzlaff advises. “Gasoline is wonderful between 10,000 and 20,000 kilometers each year. However, if you drive more than 20,000 kilometers each year, you’re a good candidate for diesel.”

Diesels, he says, are perfect for drivers who log a lot of miles since they’re fuel efficient and their drivability is on par with, if not better than, a gasoline-powered car.

“However, a low-mileage consumer will not experience the savings that a high-mileage customer will,” Tetzlaff explained. “And, in the end, it will cost them more money.” Our diesel engines are around $2,000 more expensive than gasoline engines.”

How long can a diesel sit without being driven?

“Diesel fuel can be stored for six months to a year without substantial fuel degradation if maintained clean, cool, and dry,” according to Exxon. Diesel fuel, according to Chevron, may be stored for more than a year if it is obtained clean and dry from a reputable source and kept dry.

Do diesel cars require more maintenance?

Diesel autos have higher maintenance costs than gasoline cars. This is due to the higher cost of diesel vehicle consumables such as engine oil and spare parts. A used diesel car has a better market value than a used petrol car.

Should I buy a diesel car if I do low mileage?

This is also known as “diesel car city driving,” and it is something you should avoid. It’s common knowledge among petrolheads, but it’s always worthwhile to explain why.

Low-speed, short-distance driving easily clogs your Diesel Particulate Filter (DPF). If you have a high annual mileage (imagine 10,000+ miles per year) or mostly drive on highways, the effect will be significantly slower.
