Diesel or gasoline: 5 questions you should ask yourself before choosing a motor for your car

The eternal doubt. can I buy a car diesel or gasoline? recently, a friend of my mother called me on the phone, her daughter was going to buy a new car and didn’t know if to buy it with a diesel engine or gasoline. It is a question that many buyers of a car are done before making a purchase decision. To help you decide, we suggest five questions to ask yourself before choosing motorization. You will help you make up your mind and see beyond the typical myth of the brother-in-law: “diesel, because it spends less”.

1) What will be the use of a car?

To equality of power, a diesel always will spend less fuel, but do not read beyond would be a grave error.

Is one of the most important questions. If the use of the car is going to be essentially extra-urban – whether in secondary roads, motorway or rounds – the diesel is a good option, since their fuel consumption is especially content in these circumstances. On the road nor will suffer to the systems anti-pollution of our car modern (see the article on care of the particulate filter), with optimized operation at the operating temperature and constant diet.

If you are not able to reach the optimum temperature of service, the diesel engine suffers, and to shorten excessively the life of your emissions control systems, without going further. They can also become clogged prematurely particulate filters. Very simplified: diesel for on-road, gasoline for city.

If the use of the car is going to be mainly urban, a gasoline engine is recommended. If you’re going to roll a lot of miles in city, think of a hybrid.

The reality is more gray: we use a more mixed car, but within that mix, we need to dterminar what type of driving is more frequent in our experience. If every day you take the round to go to work and all day trip, half hour traffic jam to go 15 miles – even if you do a long trip in a timely manner – buy a petrol. If you cross the Iberian Peninsula once a week, without a doubt, you’ll save a lot of money if you purchase a car diesel. Next question.


2) how Many miles do you think travel annually?

The greater part of us we don’t cross too many miles per year, the figure fluctuates around 12,000 km/year for the Spanish driver the middle. Only you are interested in a diesel engine if you travel approximately 25,000 miles per year, grosso mode. Why? Let’s go by steps: in the first place, the purchase of a car diesel is more expensive that the purchase of a gasoline. Equality of power is about 2,000 euros more expensive, and there is added the interest of the funding. Insurance and maintenance are also slightly more expensive – think, for example, in the refuelling of AdBlue in a modern diesel.

A SEAT Ibiza 1.4 TDI (110 BHP) is 1.760 euro more expensive than an Ibiza 1.0 TSI engine of 115 HP to equality of equipment and finish, for example.

breakdowns – if, touch wood – can be solved by paying bills much more expensive in the case of a modern diesel, there is simply more systems and components susceptible to failure. On the other hand, its fuel consumption is lower and the price of fuel is also lower. Where I want to get at is the payback period of a car. what is the mileage I bought the car diesel? a Multitude of online calculators offer estimates, which are valid – assuming a full mechanical reliability.

050_LEON_CUPRA_290A figure of guidance, that we may not give 100% reliable without to answer the following question. Another detail to keep in mind is if the use of the car is going to vary substantially in the coming years. You can now go through about 30,000 miles per year for business reasons, but your routine could change radically in a couple of years, for reasons as simple as retirement. My father is currently on a tour of the 35,000 km per year, but in two years will retire, and I doubt that pass the 6,000 km per year. Think long-term.

3) When do you change car?

A car diesel is amortized, on average, from 160,000 km, and the investment would be clearly cost-effective from of about 200,000 km (Acierto.com).

do You plan to change soon car? If your car is going to be small in just a decade, has no sense of the biggest financial outlay of a car with a diesel engine, you’re not going to get to redeem. how Aguantarás with your same car for 15 years? The answer should also be linked to the previous question. If you do around 15,000 annual miles but does not change car in the next 15 years, possibly amortices a car with a diesel engine – taking into account the higher cost of insurance and maintenance with respect to a gasoline.

4) Where do you live?

is Not a question indiscreet. Do you live in Madrid or in Barcelona? These big cities are developing environmental plans in which point of view are cars with a diesel engine, by its necessarily higher level of pollutant emissions. Currently, the taxation of Spanish is favorable to cars with a diesel engine – the Registration Tax is calculated on the basis of carbon dioxide emissions – but could soon break free, and come to depend on the NOx emissions. See: What are nitrogen oxides?

Nissan_Juke_Nismo_RS_prueba_2015_mapdm_21Madrid currently studying to impose restrictions of movement of diesel vehicles and old in Barcelona is posed to prohibit the entry to the city of any vehicle with more than 20 years of age. Be that as it may, the picture is not favourable to diesel vehicles, especially in city. In the future, is a tendency towards hybrid and electric, but we are not in the trade-off between motors 100% thermal and hybrid in this article. It is simply a reflection to take into account for these times in which we live.

5) do You weigh the right foot?

A question that could be interpreted in different ways. If your driving style is aggressive, you will consume more fuel with a gasoline to a diesel, in a proportional way – to be the consumption of the first more sensitive to the type of driving. On the other hand, if you enjoy your car’s performance, stretching the marches, and calling for strong acceleration the engine (and the consumption is not the priority number 1) enjoy more with a car with an Otto cycle engine in your bowels – but you probably already know that.
