15,000 km per year: petrol or diesel, what choice for your budget?

Between petrol and diesel, opting for good motorization may seem complex, but this choice weighs heavily in the economies gleaned over time and respect for the environment. Whether you're travelling mainly in the city or driving regularly on highways or long distances, it's important to know how each alternative influences the purchase price, maintenance costs, and also the resale value or the total cost of ownership.

With the adaptation of the Criterion Air regulations, the arrival of new EU directives and the gradual introduction of low-emission zones (LEZs), consciously choosing its engine will probably save you many inconveniences, such as unforeseen access restrictions.

Let's see together how all these elements combine, sometimes dragging some landmarks from the discussions between manufacturers or owners at car shows.

Evaluating your mileage – a decisive benchmark for choosing your engine

Changing the car is also a choice of motorization adapted to your driving habits. Did you know that around 15,000 km per year, gasoline and diesel are no longer in the same category in all aspects?
Many homeowners question this level, sometimes considered by garage operators as the psychological threshold of depreciation.
To unravel this really important point, we put the double bites.

Which routes really justify a diesel car in 2024?

Diesel remains relevant for regular long distances, especially on the motorway, or for over 20,000 kilometres each year.
For an urban use or a rhythm of about 15,000 km, gasoline has a clear advantage.
Marie, for example, noticed that her new daily journeys on the urban periphery no longer made diesel relevant to her real needs, notably with the increase of the ZFEs and the increased vigilance on the Crits Air vignettes.

Keep in mind:diesel is especially important for regular journeys exceeding 20,000 km/year, thanks to its low appetite for fuel and its strength on the motorway. Gasoline is more timely to travel in urban areas, as it heats up quickly and uses less on short journeys. After all, according to various experiences, many French households do not cross these thresholds every year.

Imagine Paul, a salesman who travels 20,000 kilometers a year and calculated that he was more profitable with a diesel car after analyzing fuel and maintenance expenses.
On the other hand, for Marie, the city, gasoline has proved to be ideal, especially as at the next resale, its vehicle could better position itself in a market that is more attentive to Crit-Air 1 or Crit-Air 2.

Why petrol engines are more attractive for urban routes

Gas engines reach the operating temperature very quickly, making them ideal for many stops or small trips every day.
As a result, they suffer less wear and tear than diesels in the city, and generally the purchase price remains more accessible: this feature is regularly highlighted by buyers.
At 15,000 km/year, this type of engine is still widely adopted in urban or peri-urban drivers.

In urban areas, the popularity of gasoline is hardly surprising: fast temperature rise, stamina in fragmented routes and softer acquisition prices offer a winning trio.
It is no coincidence, therefore, that there are many more petrol-powered urban cars in front of schools or in shopping malls.
The garage operators also note that some owners, concerned about the premature wear of diesels in the city, largely prefer gasoline for its simplicity in this context.

Let us specify the case of Julie, who, after careful reflection, turned to a petrol car following an annual calculation of her costs for her daily trips.
With this choice, it has managed to reduce its daily spending while adapting its vehicle to its real needs, and escapes a possible ecological malus at resale in a few years.

Purchase price – maintenance – fuel consumption: the real cost of engine choice

Going beyond the simple cost at the pump, it is to integrate that the profitability between petrol and diesel depends on various criteria.
In the end, exploring these aspects will allow you to broaden the debate beyond the mere discussions on consumption, especially if you think of total cost of ownership over the entire life cycle of the vehicle.

What is the annual budget for 15 000 km of petrol or diesel?

Gasoline usually displays at a lower price at acquisition and is accompanied by low maintenance costs.
For 15,000 kilometres per year, the fuel gap, for the benefit of diesel, no longer really compensates for the initial price surcharge, especially since fuel prices are sometimes approaching.
Julie, after completing her calculations, noticed that she saved each year with her gasoline car for her business trips, including the small revisions frequently mentioned by the approved workshops.

In summary,the cost of acquiring petrol is generally lower than that of diesel; Although diesel consumes a little less, on this mileage, this advantage does not rebalance the differences in purchase and maintenance prices.
To further refine, a user cost simulator will allow you to adapt according to your case.
Some insurance organizations also offer the possibility of integrating the green bonus or conversion bonus into your budget calculations.

Car insurance and maintenance costs: where are the real differences hidden?

Insurance for a diesel car usually costs between 10% and 15% more than for the gasoline version of the same model.
Regarding the revision, the budget also increases because some specific elements, such as the particle filter or the EGR valve, require extra attention, especially if your journeys alternate city and periphery.
For « small rollers », opting for gasoline is smart to clean his wallet — a choice validated by many testimonials gathered during events on the circular economy, particularly those in Quebec.

The insurance applied to diesel is rarely more attractive than a gasoline formula, with almost always between 10% and 15% of the difference.
Also note that the maintenance of parts such as particle filters makes the diesel side rise very quickly – it is a point that logically alarms many French households, especially during periods of inflation or for a second purchase.

How many kilometres does diesel actually become profitable?

The question is often raised: below 20,000 kilometres per year, fuel saving from diesel is generally not enough to offset the additional cost of purchasing and the higher maintenance costs.
Paul, with his 20,000 km each year, has enjoyed a definite advantage, but according to several garage operators, for the majority of households, it is gasoline that imposes nearly 15,000 km.
Some professionals also point out that it is best to consider the resale mileage and depreciation period to avoid unpleasant surprises by changing the engine.

To be noted:diesel remains the best choice especially after 20,000 km/year and for long and sustained journeys.
On the other hand, gasoline is undoubtedly the most balanced solution, given the latest analysis of the automotive market.

Environmental impact and new regulation – anticipating auto investment

From now on, choosing the right engine is about looking in depth at environmental rules, especially the famous ZFEs.
Selecting a vehicle that is compatible with these requirements guarantees you a sustainable mobility as well as the preservation of the resale value, while anticipating future changes – which avoids both a refusal of a green grey card and a bad surprise during a retrofit or resale.

• Evolution of standards:Diesels are now subject to severe restrictions in city centres, which is noted by both municipalities and car manufacturers.
• Criterion:Choosing a recent petrol car allows, in many cases, to get a Category 1 or 2 sticker, a real sesame for running in low-emission areas – mainly in large cities where rules sometimes change every year.
• Regulatory anticipation:Moving towards a motorisation that meets these future requirements will provide you with more tranquillity, while protecting your investment, especially in the face of the potential increase in ecological malus or the appearance of a new conversion bonus.

Fuel and pollution – what is the real value of petrol and diesel for urban air?

In terms of emissions, diesel releases less CO2 but emits more fine particles and oxides of nitrogen, which is problematic in the city centre.
On the other hand, gasoline, although producing more CO2, is less harmful to urban air quality.
You will thus reduce the impact on public health and probably anticipate a strengthening of regulations in metropolitan France; Gasoline is often considered a more prudent choice.
Note that some large cities already require the Criterion Air 1 to access certain municipal car parks or sporting events.

Which engine will best preserve your resale value in the coming years?

The market clearly shows that diesel cars are depreciating faster, between ecological criteria and new restrictions.
Around 15,000 km/year, a well-positioned Crit的Air gasoline model remains reassuring at resale – it is an element to keep in mind when purchasing, especially if a wave of retrofit or a change in the market is announced.

A recent petrol model, well classified according to Crit的Air, holds according to industry returns more likely to keep its rating, while diesel versions see their value decrease, especially with the new requirements and increased expectations of future owners.
