The best among diesels

To begin with, let's determine which is the most reliable engine among diesel varieties. Let's just say that recently cars with such units have become more and more popular. They are distinguished by their sporty character, speed, and stability of work. If you drive a lot and often, diesel engines are simply irreplaceable for these purposes. And if the motor is of the old generation, it has a good margin of safety despite the simplicity of the design.

Mercedes-BenzOM602

The most reliable diesel engine for Mercedes-Benz is from the OM602 family. such engines are represented by 5-cylinder versions. They have two valves per cylinder, mechanical injection pump. Drivers note that this motor is the leader in the following characteristics: car mileage and resistance to environmental influences. With not the highest power (90-130 hp), the units have always been considered the most reliable and economical. These motors were installed on Mercedes cars in the back of W124, W201 (MB190), G-class SUVs, T1 and Sprinter vans. If you monitor the fuel equipment and attachments in a timely manner, these diesel engines are capable of "winding" a huge number of kilometers.

BMW M57

Probably the most reliable passenger car engines of our time are made in Bavaria. In addition to durability, they are characterized by a sporty spirit, which in principle changes the image of a diesel engine. BMW engineers were able to prove to the whole world that such a unit can be fast, and you can put it on any type of car.
