Is a diesel vehicle really a better buy?

dieselThe general perception has always been in favour of diesel as a more economic option as far as fuel is concerned.

Experts hold the view that if you have a high usage then the savings accrued in filling the tank can offset the premium price you pay for a diesel model.
However, recent developments are beginning to raise doubts about this viewpoint.

Diesel cars cost more to buy

One of the main points to consider is that though diesel offers more fuel efficiency per gallon, there are other factors that come into play too.

The extra amount that you pay to buy a diesel model is recovered only when you use your car above 15000 miles per year.
Often, if you don’t intend to hold on to the car for long, you will not get to recover the extra initial cost of the car.
A general estimate is that it takes about ten years, if not more, for you to break even.
In addition to this, the real fuel economy becomes more obvious in bigger cars rather than in hatchbacks.

Diesel has lower CO2
A point in favour of diesel is that it does have lower CO2 emissions making it more environment friendly  in terms of your carbon foot print.

But we should not forget that diesel particulate matter and oxides of nitrogen are higher in diesel exhaust.

Another problem with diesel is that the Diesel Particulate Filter (DPF)  fitted is not particularly suited to  urban driving.

In an attempt to reduce the very harmful effects of particulate matter, the introduction of DPF has actually created a lot of practical difficulties for diesel fuel users.

It needs a steady speed of 40mph for at least 10 minutes to heat up enough to burn off the accumulated soot and then you need to drive another 15 minutes for all the soot to be cleared. This can be difficult to achieve ifyou drive a lot in town traffic.
In short, diesel cars are not meant for families that don’t use their car for long hauls. It is more appropriate for companies, if there is a lot of travelling by road.

What about petrol and gas?

There have been some  advances in petrol engines in the recent years.petrol and gas powered cars

Therefore equipped with better technology, petrol cars are now catching up with diesel in fuel efficiency.
As petrol now costs less than diesel too, the benefit that you get from diesel is not as great as it used to be.
In fact, you can say that if fuel economy is your only consideration, even then buying a diesel may not be the better option.

A diesel engine may be sturdier but it has to work under high pressure with a lot of complex adaptations.

This means that it requires regular maintenance like fuel filter changes for optimal performance. In addition diesel equipment like injectors and pumps are expensive of they need to be changed.   On the other hand, a petrol car demands less regular servicing.

However, diesels offer more torque and power than petrol cars.
The verdict now seems to be tipping in favor of petrol cars for limited urban users while diesel would be for people who move long distances or need the extra power that only diesel can provide.
