What Is High Mileage For A Diesel Engine

What Is High Mileage For A Diesel Engine?

Long distance driving is a key point in understanding what vehicle and what engine you have. After a certain point of long driving over the years, you get to reach a threshold where your engine would now be referred to as a high-mileage engine.

Although the threshold would be different for every type of engine, some would only need about 350,000 miles while others go up to 750,000 miles.

Should You Buy A Car With High Mileage?

This video discusses the pros and cons of buying a car with high mileage. The pros include having a cheaper price, if you plan on driving only a few years, etc. Also, the downside is that you might have to repair the car more times than a newly bought car.

You would be guided towards spending more time checking up on your car as it might just break down on you one day.

How a diesel engine works

Frequently Asked Questions

How many miles does your diesel engine last?

On average, gasoline engines would last up to around 200,000 miles before you need to replace them or upgrade them with a newer one. On the other hand, diesel engines last for more than 500,000 miles before needing to change.

Two hundred thousand miles would be child’s play compared to what heavy-duty diesel trucks do. With trucks mainly used for towing or hauling, these engines get about 200,000 to 300,000 miles. Those numbers would still command a good price for reselling their trucks, even with that mileage.

Since diesel engines last longer than gas engines, it would be unfair not to commend them for their versatility. A vehicle with high mileage would vary its values depending on the engine type.

Diesel engines are usually better than gas ones. A pickup truck with a couple hundred thousand miles would still resell for a good amount.

Should you change oil with high mileage?

It would be wise to have your vehicle serviced once a year, especially if it is nearing the MOT test time. In addition to this, you also have to make sure that you change your engine oil annually, even more so if you have high mileage.

Oil is the one lubricating your engine, making everything run smoothly. Diesel engines rely heavily on pressure and heat to function properly, unlike their other gas counterparts. This dependence makes the metal and the parts get stressed and, without lubrication, would result in the engine wearing and tearing much quicker than it is supposed to be.

Should You Buy A Diesel Engine For Low Mileage?

No, you should not buy a car with a diesel engine to let you drive short distances. Driving at these speeds and lengths would not help your Diesel Particulate Filter (DPF) unclog. Due to the low speeds, there would not be enough heat to burn through it, making it clogged.

While car manufacturers give unclogging guidelines for these vehicles, it often goes wrong. The high probability that the execution fails would be expensive to repair. It could go for up to 1,200 euros depending on the gravity of the maltreatment of the engine.

For comparison, petrol or gasoline cars typically only require a catalytic converter to handle their emissions. Generally, these converters are also found in diesel engines.
