Why don't Russians Choose Diesel Engines – Financial calculation

Why don't Russians Choose Diesel Engines – Financial calculation

19.12.2014
What is economically better for Russians – a petrol or diesel engine?

The Europeans gladly prefer diesel fuel, but Russians don’t hurry to abandon petrol. Maybe, diesel fuel is not so appropriate, as it’s commonly believed? To clarify this question, we need to calculate the total price of the service, considering different engine types for each model. For example,the Renault Duster, Nissan Qashqai and Skoda Octavia.

Petrol VS Diesel: pros and cons

Both types of engines have both positive and negative characteristics. For example, the petrol engine is more distributed, so there is no problem with spare parts. But the petrol engine "drinks" more and has less torque. However, it’s more powerful than the diesel engine and easily spins up to higher speeds.

Diesel vehicles traditionally have better performance, because this type of engine consumes less fuel.

The flaws are obvious: the high price to install it and its weight (this engine always needs a powerful engine block). In addition, diesel vehicles need original spare parts which are hard to find in the Russian service station.

Moreover, repairing the diesel engine hits the wallet much more than the petrol engine.

Renault Duster: Petrol VS Diesel

The crossover’s heart of the French company is1.6-litre and 2.0-litre petrol engines or a 1.5-litre diesel engine.

With the diesel engine, the starting price is 679,000 roubles. With the petrol engine, it costs 614,000 roubles. The price of the annual fuel consumption with an annual mileage of 20,000 km in different cycles will be 35,510 roubles (for diesel) or 57,859 roubles (for petrol). With the diesel engine, the car needs maintenance after every 10,000km (twice a year). It costs 18,400 roubles. With the petrol engine, you need maintenance after every 15,000km. So, its annual maintenance is 8,300 roubles.

Let’s summarize the expenses.

The diesel Renault: 679,000 (car price) + 35,510 (annual fuel consumption) + 18,400 (maintenance twice) = 732,910 roubles.

The petrol Renault: 614,000 (car price) + 57,859 (annual fuel consumption) + 8,300 (maintenance once) = 680,159 roubles.

As a result, the car with the diesel engine is more expensive even though fuel consumption is almost twice as low.

What if it's fair only in France, but not in other countries?

Nissan Qashqai: Petrol VS Diesel

The trendy Japanese crossover might be equipped with 1.2-litre or 2.0-litre petrol engines or 1.6-litre turbo diesel engine.

With the diesel engine, the car costs 1,127,000 roubles. The fuel consumption is 4.5 litres per 100 km on the highway; 5.6 litres per 100 km in the city. The estimated consumption in the combined cycle driving is 4.9 litres. The annual travel with the diesel Qashqai, averaging 20,000 km, would require 32,830 roubles for fuel. The maintenance after every 20,000km costs 9,739 roubles.

With the petrol engine, the crossover costs 1,042,000 roubles. To drive an average 20,000km annually, you have to pay 48,576 roubles (5.5 litres per 100km on the highway; 9.2 litres per 100km in the city). The petrol engine should be maintained every 15,000km which costs 6,510 roubles.

So, buying a new Qashqai and driving it for a year, you will spend 1,169,569 roubles for the diesel version or 1,097,086 roubles for the petrol version.

However, not everyone wants to drive a crossover. Let’s estimate the car with another body type.

Skoda Octavia: Petrol VS Diesel

The Czech hatchback can be equipped with 3 different petrol engines or a 2-litre turbodiesel engine.

We will compare the diesel engine to the similarly powered 1.4-litre petrol engine.

The diesel Skoda costs 964,000 roubles. The annual diesel consumption with a mileage of 20,000km in different cycles (4.3 litres per 100km on the highway; 6.4 litres per 100km in the city) is 34,170 roubles. The maintenance after every 15,000km costs 8,702 roubles.

With the 1.4-litre petrol engine, the car is available for 864,000 roubles. A year's supply of petrol for an average of 20,000km, costs 37,312 roubles. The Eastern hatchback has almost no difference in price to fill different types of fuel. The maintenance after 15,000km costs 7,495 roubles.

Thus, the annual fuel consumable costs 1,006,872 roubles for the diesel engine and 908,807 roubles for the petrol engine.

Consequently, Russians have a reason not to change petrol engines to diesel. The maths shows that it’s just more expensive.
