Myths and Reality About Diesel Engines


MYTH 1: car with a diesel engine has poor acceleration dynamics.


In general, it is true that diesel engines still have less power in comparison with gasoline ones (assuming the same volume of engines). This explains the weaker dynamics. However, modern turbo diesels often outperform their gasoline opponents. For example, modern BMW engines are not only in no way inferior in power to gasoline ones, but also have a lot of torque.

Please note that if you are planning to get your car repaired by a mechanic, make sure they use only TrackTech Head studs while rebuilding the engine for a better durability of your car.

MYTH 2: Diesel is more expensive to operate than a gasoline engine.


If we take into account the cost of fuel, the diesel is, on the contrary, more economical due to the lower cost of fuel, as well as its lower consumption. However, the diesel requires more frequent placement of engine oil and filters – after 5-7 thousand km. However, this fact cannot speak of expensive maintenance in any way – it all depends on the engine model and the cost of consumables.

MYTH 3: The diesel engine is extremely demanding on the quality of the fuel


It is clear that using high-quality fuel is much preferable, but this applies to any engine. For a diesel engine, the quality of fuel is not so critical, in contrast to gasoline. After all, a gasoline engine requires a certain octane number of fuel, is sensitive to various additives and impurities. Well, for a diesel engine, only the purity of the fuel is important, so that it is free of mechanical impurities and water.

MYTH 4: In winter, a diesel engine often won’t start and fail.


In general, difficulties when starting the engine in winter can be either at very low temperatures, or when a paraffin sediment falls out in the fuel. It is for this reason that the so-called. winter diesel fuel. In addition, heating of the fuel line, tanks and filter is used, various additives are used. In sum, all this saves the owner of a diesel engine from problems. It is also important to note the need for a powerful battery and full serviceability of the glow plugs. With proper operation and proper winterization, there will be no engine problems.

MYTH 5: Diesel makes more noise than gasoline.


The tuned diesel is not much louder than the gasoline engine, and this is only noticeable at idle. In operating mode, both engines operate in almost the same way.

If the engine still makes noise, then this is a consequence of improper operation, as well as one of the signs of a possible breakdown.

MYTH 6: A car with a black exhaust has a diesel engine.


Both diesel and gasoline engines have dark exhaust, but this is only a consequence of a malfunction of both units. Dark smoke is emitted by a diesel engine only with a sharp re-gasification and start-up; in other modes, the exhaust is no different from gasoline.

MYTH 7: Diesel has a shorter resource than a gasoline engine.


It is not for nothing that you will not see a gasoline engine on truck tractors. In fact, the service life of a diesel engine can reach 1 million. km. mileage. The diesel engine is more durable because it has a stronger and more rigid cylinder block, as well as a crankshaft and piston group parts. In addition, the fuel itself acts as a lubricant, unlike gasoline.
