Diesel vehicles are in high demand. In some cases, such an aggregate makes considerable sense. However, one should not forget that such power plants also have very specific disadvantages. The most important of them will be discussed today.
1. A question of price
Diesel installations attract many motorists with their efficiency. However, do not forget that diesel is much more difficult to manufacture from a technical point of view. Hence the increased price of such a motor by 30-40%. The difference in the cost of gasoline and diesel cars does not pay off due to fuel economy by no means as quickly as many would like.
2. Service frequency
A diesel engine is a much more demanding installation in terms of the frequency and quality of maintenance. As a result, oil, filters, gaskets and many other consumables change much more often in such units. Is it necessary to say that their purchase naturally hits the pocket of the driver?
3. Repair cost
On average, the repair of diesel installations, especially overhaul, is significantly more expensive than the repair of gasoline engines. The main reason for this lies in the already mentioned technical complexity of such installations. Even replacing injectors or spark plugs can cost a lot of money to a motorist.
4. Fuel options
For diesel engines, fuel is produced in summer and winter versions. If you do not want to spoil the engine of your favorite car, then the driver must not forget to make a timely transition. Already at minus 5 Celsius, summer grades of fuel begin to thicken, and at minus 10, they freeze.
5. high mass
Diesel engines are noticeably heavier than gasoline engines. Therefore, with comparable performance parameters, the dynamics of a diesel car will be lower than that of a gasoline car. The weight of the engine also affects the maneuverability of the car, as well as its stability and ability to overcome obstacles.
6. Noise and vibration
Diesel engines operate at much higher pressures than gasoline engines. The problem is that all this leads to the appearance of clearly visible noise and vibration. Especially for car models with “simpler” units. All this forces drivers to spend more, including on high-quality sound insulation.

7. Emissions
Finally, do not forget that diesel engines are noticeably dirtier than gasoline ones. They give much more exhaust, which makes it mandatory to use systems to reduce toxicity with such installations.
