Diesel Rule 3: Don’t buy diesels for low mileage or inner city life. … Driving at low speeds and short distances clogs up your Diesel Particulate Filter (DPF) quickly. The effect of this is much slower if you have a high annual mileage (think 10,000+ miles per year) or drive mainly on motorways.
Is it OK to drive a diesel short distances?
If you cover a high mileage and the bulk of your driving’s on motorways, then a new diesel (with a DPF) is still a good option. If your driving is predominantly short journeys on local roads, then petrol will be more suitable than a diesel because Diesel Particulate Filters don’t like short journeys.

Is it worth buying diesel in 2020?

Even if the latest technologies are cleaner, they are not clean enough, particularly if not well-maintained and run mainly on short, cold local journeys.
Do diesels need to be driven hard?
Driving a diesel engine hard will produce less soot per kWh of useful work. … Driving a diesel hard will also use more fuel. Use the torque which is what a diesel is about and let the DPF sort itself out as necessary, it works for most people like that.
Why do diesels rev so low?
The longer the stroke length more will be the velocity of piston on particular RPM resulting in more momentum of piston. More the momentum more will be torque applied to crank on particular RPM. … Most Diesels are lower in rpm because Diesel fuel ignites slower. Even racing Diesels won’t rev past 5,000.
What is considered high mileage for a diesel?
Generally speaking, diesel trucks are sold with higher mileage than the typical used vehicle. It is not uncommon to see a used diesel truck for sale with over 200,000 miles on it.

Does driving slower save fuel?
Going slower technically saves fuel because at high speed your engine needs to work harder to overcome drag from wind resistance, your tyres and transmission, and that drag increases exponentially the faster you go. Reduce your speed, then less power (and thus fuel) needs to be expended to overcome that drag.
Does missing out gears save fuel?
However, by skipping a single gear while shifting up, or by missing out gears when changing down, you could save a significant amount of fuel. … Driving in a higher gear than necessary can also improve fuel economy, as long as the engine isn’t struggling.
What car is best for short journeys?
The best cars for short journeys are ones powered by gas, hybrid or all-electric powertrains. Diesel-powered vehicles are best at long trips and not for repeated short journeys, so they are probably the worst type of vehicle of all for that type of use.
