How Many KMs Can A Diesel Car Last?

My licensed mechanic informed me that a diesel engine may travel 500,000 kilometers and still be in excellent condition, even if it begins to make noise or burn oil as it ages.

How many kms Can a diesel engine do?

I’m preparing to purchase a new vehicle and am considering a diesel engine. I’ve heard they’re less expensive and better for the environment, but is this truly the case? – Emma lives in Edmonton.

Your values, finances, and driving habits will all influence which option is best for you. What are the benefits of diesel fuel, which is currently equal to, if not more expensive than gasoline, and a higher purchase price for a diesel-powered vehicle?

The fuel economy of a diesel engine is unquestionably superior, which is why they are so popular in Europe. A diesel engine will also survive significantly longer than a gasoline one.

“A gas engine can go up to maybe 250,000 km or 300,000 km before it starts to produce noise or burn oil because it’s wearing down,” says one trained mechanic I talked with. “However, a diesel engine can easily go 500,000 km and still be in fantastic health.”

“This is due to the fact that diesel is a very light oil, and burning diesel in an internal combustion engine essentially lubricates the valves, rings, and piston walls.” Both gasoline and diesel are made from petroleum, but gasoline is a powerful detergent that constantly cleanses any oil from engine components.”

Most mechanics think that if a diesel car is properly maintained, it can last for up to 30 years. They do, however, necessitate some extra attention. For example, you can’t expect a diesel to start readily after sitting all day in sub-zero temperatures. You’ll probably need starting fluid to get the engine started in an Edmonton winter.

Diesel engines endure longer, but they are more expensive to maintain. Diesels, for example, have a complex and expensive fuel pump. Furthermore, any water passing through a diesel’s injectors or distribution pump will do significant harm, thus the engine oil filters are likewise special. These additional filters must be replaced on a regular basis, and they are not inexpensive. A particular water separator filter, for example, can cost up to $100 and keep moisture out of the gasoline.

Fuel availability is another a factor to consider, since not all service stations sell diesel, so you’ll want to be sure you have a reliable supply.

Let us now turn our attention to the environmental consequences. Which sort of car is the best? That depends, according to Dr. David R. Boyd, a Simon Fraser University adjunct professor of resource and environmental management.

“In terms of used vehicles, diesels are more efficient (emitting fewer greenhouse gas emissions), but dirtier (producing more conventional air pollutants, including particulate matter),” Dr. Boyd explains.

“When it comes to new automobiles, hybrids are at the top of my list. There’s a reason why cab fleets have all adopted them.

“Hybrids outperform other vehicles in terms of fuel efficiency and pollution reduction. New diesels, combined with new legislation demanding ultra-low sulphur diesel fuel, are significantly cleaner than older diesels. Dr. Boyd, whose latest book is Dodging the Toxic Bullet: How to Protect Yourself from Everyday Environmental Health Hazards, argues that concerns about particulate matter, nitrogen dioxide, and air toxics remain.

Diesel engines are unquestionably more efficient than gasoline engines, therefore your fuel bills will be reduced if you drive a lot of miles. However, in terms of fuel economy and emissions, there are better options for the environment these days, so if you have the extra cash to spend up front, why not try a hybrid?

Is 200 000 km on a diesel too much?

Buying a used automobile can be a difficult undertaking, and you need think about a lot of things before signing the final piece of paper. However, checking a used car’s odometer for the number of kilometers it has driven in its lifespan is one of the simplest methods to obtain a quick feel on its value and how much life it has left.

There are several factors to consider in addition to the odometer reading. The mogo team strives to place its customers in their ideal vehicle at the best possible price and to give you with as much information as possible about your future used automobile purchase. To aid in this endeavor, we’ve compiled a list of items to look for when purchasing a secondhand vehicle.


As previously stated, miles are not the only metric for determining how much use a secondhand car will get. While it provides a decent, if speculative, picture of how much abuse the used automobile has taken over the years, the overall condition of the used car is far more important.

If there is any visible bodywork damage, or if a used automobile reaches the crucial 200,000-kilometer milestone, its value drops dramatically. The latter, on the other hand, isn’t always a hint that the secondhand car isn’t in good shape.

It’s usually a good idea to look over a used car’s service history, because if it hasn’t been consistent, it could be a red flag. Most cars with a reliable service history and roughly 200,000 kilometers on the clock should be a good buy if the price is right.

Of course, rare, older automobiles will have huge numbers on the odometer, but if they’ve been well cared for by a conscientious owner, those statistics won’t mean nearly as much.

The Numbers on the Dashboard Tell the Story

It pays to conduct some research before buying a used automobile with a questionable number of kilometers on the odometer. There is a wealth of information available on the internet about which makes and models have stood the test of time and which have faltered.

A automobile travels roughly 20,000 kilometers per year on average, therefore if the vehicle in issue has traveled more than this, there are certainly better options available. Rust is another deal breaker because it will only get worse with time, and parts for imported cars are generally rather expensive.

Most cars with more than 300,000 kilometers aren’t worth your attention unless you have prior experience working on cars and the price is appealing.

At mogo, we work hard to match our users with the exact automobile they’re looking for, and we’ve developed a system that ensures they always receive the greatest deal! Join the mogo team today and start looking!

How long can diesel cars last?

The ban on new petrol and diesel vehicle sales will put an end to all new petrol and diesel vehicle sales. From 2030 onwards, new trucks, vans, and any other combustion-powered vehicle will be prohibited from being sold.

The notion of prohibiting all new petrol and diesel automobile sales in the UK was first proposed in mid-2017, with a target date of 2040 set as the start date. However, in the United Kingdom, we are currently in the midst of a tremendous push for greater sustainability. Boris Johnson announced the government’s ten-point plan for a “green industrial revolution” in the UK at the end of 2020 — a determined push over the following two decades to make the UK a global green leader.

One of the plan’s main objectives is to hasten the transition to zero-emission automobiles. As a result, the ban, which had previously been pushed back to 2035 in February 2019, has now been pushed back to 2030, with a speedier transition thought possible due to increased EV production and feasibility.

Will I have to scrap or convert my current petrol or diesel vehicle?

The change in regulations will not require you to scrap or modify your current combustion-powered vehicle. The restriction only applies to new automobile sales, therefore existing gasoline and diesel vehicles will continue to be permitted on the road after 2030. Diesel automobiles are likely to be on our roads until at least the mid-2040s, as the average diesel car has a 14-year lifespan. So, if you want to keep driving a gasoline or diesel automobile, you can, but you’ll have to accept the shifting costs and laws that come with them. Many areas are likely to follow London’s lead and implement ultra-low pollution zones, therefore the petrol and diesel car ban will likely make combustion cars financially and practically unviable in the future.

It is feasible to convert your current gasoline or diesel vehicle to electric, but the process is now prohibitively expensive, with costs ranging from £20,000 to £60,000. That renders almost any conversion project pointless, especially as EV prices continue to fall.

Do diesel cars need long runs?

  • Petrol automobiles use more fuel and emit more carbon dioxide than diesel cars (CO2).
  • Diesel cars emit more hazardous emissions depending on the ‘Euro’ standard in effect at the time the vehicle was purchased.
  • The costs of servicing gasoline and diesel vehicles are comparable. At least once a year, both require servicing, notably an oil change.
  • Diesels have a shorter rev range but a lot of torque, so they’re better for towing and more adaptable on highways or hills where fewer gear changes are required.
  • Although petrol is slightly less expensive at the pump, diesel’s superior fuel economy should result in annual savings on your fuel expense. If you have to spend more for a diesel car in the first place, the savings from lower fuel expenses could take several years to recover, depending on your annual miles.
  • Diesels, particularly those manufactured prior to 2015, are increasingly likely to be charged or barred from entering big cities.
  • Diesels with a Diesel Particulate Filter (DPF) require frequent long runs, some of which must be done at high engine speeds to clean (regenerate) the filter, making them unsuitable for largely short, local trips.
  • To minimize emissions, newer diesel cars employ AdBlue, an exhaust fluid that breaks nitrogen oxide gas down into harmless nitrogen and water vapour.
  • The first year of car tax is dependent on CO2 emissions, so diesels may be cheaper at first, but from the second year on, a flat charge of £140 applies to both petrol and diesel.

Is it OK to buy a car with 200k km?

Used Cars With Low Mileage Are Usually In Better Shape In most cases, this is correct. A car with over 200,000 kilometers on the odometer that has been well-maintained throughout its life would be a far better investment than one with 75,000 kilometers on the odometer that has been mistreated by a previous owner.

How many km is good for a used car?

Despite the current trend, some people are still prepared to purchase a used car from a stranger’s driveway. We’ve put together a list of ten pointed questions they should be asking.

1. Request a phone description of the vehicle from the vendor.

If the seller inquires, “You’ve got yourself a curbsider — a scam artist who poses as a private vendor and sells many vehicles. It’s pointless to praise criminal behavior. Put an end to the conversation.

2. What is the mileage on the odometer?

The average car will travel 20,000 kilometers per year, which is the distance used by manufacturers to establish standard warranty coverage. The odometer on a seven-year-old model should read 140,000 to 150,000 kilometers. Deduct money for excessive mileage if it has traveled significantly more.

3. Are you the original owner of the property?

Yes is the optimal response. A creampuff is a one-owner used automobile. You might query the owner about oil change intervals and other maintenance practices. There should be no hidden agendas. Because of this, one-owner cars command a higher price.

If not, how many times has the automobile been passed down through the family? The ownership history can be found in a Used Vehicle Information Package (UVIP), which the vendor should have on hand. Is there an excessive number of owners? Probably a difficult vehicle that is costly to maintain.

4. Do you have a copy of your service records?

At the very least, any respectable seller should have some repair receipts. Keep an eye out for costly engine or transmission repairs. Be wary of any seller who claims to have no records. He could be flipping a car he bought from someone else, and he doesn’t want you to find out about its shady past.

5. Is it possible for me to take it for a test drive?

If the answer is no, you should leave. Anyone who can’t give up the car for a little spin is probably concealing something (it may not be plated properly). And don’t settle for a simple lap around the block. To gain a sense of the vehicle’s mechanical fitness at speed, drive it on the highway. Turn off the radio and listen for strange noises like suspension knocks or a whining transmission – or a whiny spouse.

6. Does it have a safety certification?

There’s no need to acquire a certified automobile. In fact, having your expert assess the car and make the necessary repairs to your satisfaction is preferable. Because the Ministry of Transportation does not keep track of certificate books assigned to garages that have gone out of business, unscrupulous garages are selling safety certificates without seeing them.

7. What is the reason for selling the vehicle?

If they say they’ve ordered a new automobile, they’re plainly trying to negotiate a better deal than the new-car dealer’s lowball offer. If they’re selling an automobile that belongs to a family member — “My old father can no longer drive” — make sure the ownership slip matches the UVIP printout.

8. Has it ever been in a car accident?

Even if the seller lies and says no, a short inspection for paint overspray will reveal the deception (inspect window and door seals, wheel wells and mufflers). The vendor will almost always under-report the crash damage. If you’re still interested, have it hoisted by a professional.

9. Is it okay if I bring it to my mechanic?

To be fair, wait until you’re certain you’ve decided on a vehicle before doing this. A garage visit takes time, and the owner may or may not wish to be without his or her car for a day. It’s best to make arrangements with your mechanic ahead of time, especially if he or she is available on Saturday.

10. Would you be willing to accept a lower price?

How many km should a car last?

Cars can endure between 200,000 and 300,000 kilometers if properly maintained. Your vehicle’s manufacture and model can also play a role. The following are the top automobiles that have been known to last over 200,000 kilometers.

Is 300k miles alot for a diesel?

When it comes to mileage, according to Prosource Diesel, diesel vehicles frequently receive better mileage than gas trucks since their engines are more durable. As a result, according to Prosource Diesel, it’s not uncommon to find a used diesel truck with more than 200,000 kilometers on the odometer. There’s a good chance you’ll stumble across a used diesel vehicle with 300,000 miles on the clock.

What constitutes excessive mileage in the case of specific diesel engines? According to Prosource Diesel, a secondhand diesel truck with a Cummins or Duramax engine with more than 350,000 kilometers is considered excessive mileage. For a Powerstroke diesel engine, anything above 350,000 miles is considered high mileage.

How often should I take my diesel car on a long run?

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:
