Short excursions do not allow the diesel engine to warm up sufficiently to remove deposits and prevent carbon accumulation and combustion. That’s all there is to it. To get it up to temperature, you’ll need at least 15-20 minutes of loaded running and at least 1 hour of highway travel per month to keep it happy.
What is considered a short journey for a diesel?
To begin with, small journeys. Any engine is inefficient while it is cold, thus regardless of the vehicle’s quoted fuel economy, the first 15 minutes or so of any journey will not give particularly excellent fuel usage. So, if your journey consists of a brief commute to work or a trip to the store, a diesel or petrol automobile will provide low fuel economy.
Second, there’s the issue of stop-start driving. Even if your engine has fully warmed up, if you are constantly speeding, braking, and sitting at traffic lights, it will not run efficiently.
Because a diesel engine has a tendency to lag and be a little more sluggish off the line than a comparable petrol engine, but is stronger once it gets up and running, there is a tendency to put your foot down harder to get it to respond, only to have to lift off or even brake again to slow it down as it approaches 20mph.
This type of driving consumes more fuel than applying the accelerator and brake smoothly. Driving a diesel smoothly is undoubtedly doable, but it needs some expertise and constant expectation. Meanwhile, idling at traffic signals consumes fuel regardless of whether it is gasoline or diesel, so you are squandering both.
Does diesel car need to be driven daily?
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.
Should I buy a diesel for short journeys?
Simply said, if you drive a lot of high-speed miles on a regular basis, such as a regular highway commute rather than a lot of small excursions, you should get a diesel automobile. Diesel cars have higher fuel economy than their gasoline counterparts, as well as more torque for towing and other applications.
Diesel car prices are currently falling as a result of diesel’s demonization in recent years due to its health and environmental consequences. As a result, used diesel car costs seem appealing, but they are only suitable for a certain sort of driver. If you misuse a diesel car or purchase an older model, you could face high fines and perhaps be barred from driving in city centers.

Should diesels be driven hard?
A diesel engine that is driven hard produces less smoke per kWh of useful work. Period. Forget about the brief puff of black smoke that occasionally appears as the turbo spools up. What important is the overall effect.
A diesel engine that is driven vigorously will consume more fuel. Use the torque that a diesel engine is known for and let the DPF sort itself out as needed; it works for most people.
Do I need to worry about DPF?
As previously stated, it can occasionally be resolved by taking a lengthy drive; if this does not work, take your automobile to a mechanic.
Remember that orange warning lights are merely advisory; red warning lights, on the other hand, demand immediate attention and frequently compel you to stop the vehicle as soon as feasible.
