FIND CARS BY ENGINE CODE AND UNDERSTAND WHAT THE ENGINE CODE REALLY MEANS

What is a car engine code?
A car engine code is a unique identifier assigned by the manufacturer to a specific engine family, for example B47D20, G14D, M112.913 or DV6TED4. This code works like an ID number for the engine design. It helps to identify which engine is installed in the car, to order correct spare parts, to check the correct oil type and capacity, and to find other cars that use the same or very similar engine. The engine code can usually be found in registration documents, on a metal plate or sticker in the engine bay, stamped on the engine block, or in the manufacturer’s electronic catalog.
Does the same engine code always mean exactly the same engine?
Not always. In most cases, the same engine code means the engines are very similar in basic design, such as the block, head and general architecture. However, there can be differences between engines with the same code, for example different power outputs, different ECU software, different emission standards, different turbochargers, injectors or sensors, and technical updates introduced during production. In addition, the same engine type can sometimes be installed in different models and even different brands within the same manufacturer group or partnership (for example one engine used in both Brand A and Brand B cars). Because of this, two engines with the same code are usually from the same family but not necessarily 100 percent identical. When comparing engines by code, it is important to also check production year, power (kW or hp), fuel type and sometimes even the target market (Europe, USA, etc.).
Why is the same engine used in different car models and brands?
It is very common that one engine type is used in many different models and even in different brands. Large automotive groups design an engine once and then install it in many cars with different bodies, sizes and purposes. For example, the same engine can be used in a hatchback, sedan, MPV or small van. In addition, some manufacturers cooperate and share engines through partnerships or joint projects, where one brand develops a diesel or petrol engine and another brand buys and uses it. Reusing the same engine in many models reduces development costs, simplifies logistics for spare parts, and makes maintenance easier because parts are more common and easier to find. It also helps manufacturers to meet emission standards using a proven engine instead of designing a completely new one every time. Because of this, one engine code can appear in many different cars that look very different from the outside, sometimes even under different brand names.
Does an engine with the same code always use the same oil and the same oil capacity?
Here it is important to be careful. Engines with the same code usually use the same general oil technology, for example 5W-30 or 0W-40 fully synthetic oil, but the exact required specification can change. Oil specifications and approvals (such as ACEA, API or manufacturer approvals like VW, BMW, Mercedes, Ford) may be updated over time. Newer versions of the same engine may require newer approvals because of stricter emissions or because the car has a diesel particulate filter or gasoline particulate filter. Some versions must use low SAPS oils, while older versions could work with standard oils. Because of this, the engine code alone is not enough to choose oil. Always check the manufacturer’s official recommendation, production year, emission standard and whether the car has DPF or GPF.
Oil capacity can also differ for engines with the same code. The reason can be a different oil sump design, a different drive layout (front wheel drive, all wheel drive), technical updates during a facelift, or changes in the oil cooler or filter housing. Two cars with the same engine code can have slightly different oil fill volumes, for example 4.5 litres versus 4.8 litres. For this reason, it is safer to look at engine code together with model, year and power and to use reliable data sources.
What else is important to know about engine codes?
Engine codes are a powerful tool for identifying engines, but they should always be combined with official data. It is recommended to confirm details with the manufacturer’s documentation, reliable online catalogs or VIN based information. During a model’s life cycle, the same engine code can be updated internally, for example with new sensors, revised injection or strengthened components. Many parts still fit, but not always one to one, so blindly assuming everything is identical can cause problems.
If the engine has been modified or tuned, for example chip tuning or turbo upgrades, then the original oil recommendation and service intervals may no longer be sufficient. More frequent oil changes or higher quality oil may be needed. Engines with the same code often share similar timing belt or timing chain intervals and typical weak points. By finding other cars that use the same engine code, you can better understand common problems, symptoms and preventive maintenance.
How this information helps you
By using the engine code together with car model, production years and engine power, you can find which cars use the same or very similar engine family. This helps when you are looking for compatible spare parts, trying to understand known issues of a particular engine, comparing cars with the same engine or checking which oil specification and approximate capacity may be required. Always treat the engine code as a strong starting point, but confirm details with official specifications for the safest and most accurate result.
