Dieselmotoröl und Benzinmotoröl sind zwei der am häufigsten verwendeten Ölsorten auf dem Markt. Es entstehen jedoch viele Fragen bezüglich der Unterschiede zwischen diesen beiden Öltypen und ob sie untereinander austauschbar sind. In diesem Artikel beantwortet AutoX Furion diese Fragen.
Unterschiede zwischen Diesel- und Benzinmotoren
dầu nhớt động cơ diesel
Ein Benzinmotor verwendet Benzin als Kraftstoff. Dieser Motor erzeugt Leistung durch die Verbrennung eines Kraftstoff-Luft-Gemisches im Zylinder, ausgelöst durch einen elektrischen Funken einer Zündkerze.
Ein Dieselmotor verwendet Dieselkraftstoff (DO-Öl). Dieselmotoren erzeugen Leistung durch die Verbrennung eines Kraftstoff-Luft-Gemisches im Zylinder; es gibt keine Zündkerze.

Neben ihren Gemeinsamkeiten hat jeder Motor seine eigenen Vor- und Nachteile.
1.1 Vorteile von Dieselmotoren
Diesel engines have higher efficiency than gasoline engines (1.5 times).
Diesel fuel is cheaper than gasoline.
Diesel engines have lower fuel consumption than gasoline engines.
Diesel fuel does not ignite at normal temperatures, making it less dangerous.
Because they lack carburetors and ignition systems, diesel engines experience fewer minor malfunctions.
Diesel engines handle overloads better than gasoline engines.
1.2 Nachteile von Dieselmotoren
Despite the superior advantages of diesel engines as mentioned above, they still have some unavoidable drawbacks:
For the same power output, diesel engines are heavier than gasoline engines.
Diesel engines have a higher compression ratio, requiring higher quality engine components. This leads to higher manufacturing costs.
The fuel system components in diesel engines are highly precise (error margin of only about 1/100mm), such as the high-pressure pump and fuel injectors, resulting in higher manufacturing and repair costs.
Repairing diesel engine components requires specialized machinery, expensive tools, and highly skilled technicians.
Diesel engines operate at lower speeds than gasoline engines.
Diesel engines are noisier and have a stronger odor than gasoline engines. However, these issues have been addressed with advanced technologies.
- Kann Dieselmotoröl in Benzinmotoren verwendet werden?
For multi-purpose oils, the answer is yes. For example, engine oil with an API CH 4/SL rating means it’s a H-grade oil for diesel engines and an L-grade oil for gasoline engines.
However, it’s preferable to use it for gasoline engines, and when using oil, you must adhere to the engine manufacturer’s instructions regarding SAE, API ratings, and oil change intervals. The engine type indicated by the „/“ sign (S or C) indicates the preferred engine type.
- Welche Motorölsorte sollte für Diesel- und Benzinmotoren verwendet werden?
Currently, experts recommend using specialized engine oil for each type of diesel engine based on criteria such as: fuel efficiency, compliance with emission standards, total alkalinity, soot dispersion, and protection of the engine’s exhaust systems.
Some characteristics of engine oils for gasoline and diesel engines:
Viscosity: Gasoline engine oil generally has lower viscosity than diesel engine oil due to the harsher operating conditions and higher load of diesel engines.
Exhaust system: The particulate filter (DPF) in a diesel engine operates in a harsher environment than in a gasoline engine, leading to higher soot contamination and higher temperatures in the oil. In gasoline engines, the EGR (Electro-Recirculating Gas) filter increases the amount of hot air in the combustion chamber, resulting in more oxidation products.
Additives in oil: Diesel engine additives contain high levels of sulfur and phosphorus (SAPS), which have a greater impact on catalytic converters that remove NOx: SCR (Selective Catalytic Reduction).
Other factors: Gasoline engines prioritize good dispersion, while diesel engines focus on the alkalinity (TBN – Total Base Number) of the diesel engine oil.
Choosing the right engine oil requires drivers to have a thorough understanding of their vehicle. If you’re still unsure about the right oil, consider AutoX Furion.
