2021 Subaru Legacy Engine Options


Subaru / Boxer-4 / Subaru Four-Cylinder Engines - Petrol / FB / FB25D

Engine manufacturer
A car and its engine do not always share the same manufacturer. Sometimes the engine and other components can be borrowed from other manufacturers.
Subaru
Engine family
Usually in the same family are engines with the same volume and layout. Some parts of the same engine family may be interchangeable with each other.
Subaru Four-Cylinder Engines
Engine series
Each individual engine series has its own design features and is installed on certain vehicles.
FB
Displacement
The more cylinders in the engine and the higher their total volume, the more powerful the car is considered. On the other hand, the more cylinders an engine has, the higher the fuel consumption.
2.5L H-4
Oil capacity
Keep an eye on the oil level in the engine. If it is too low, it can cause a breakdown, because all its elements must be abundantly lubricated during the operation. If it is too much oil, it will interfere with normal engine operation and create excessive resistance.
4.4 quarts
Oil viscosity
Different engines require different viscosity grades of oil, which are specified by the engine manufacturer. These viscosity grades are typically denoted by a number and a letter, such as 5W-30 or 10W-40. The number represents the oil's viscosity at low temperatures, while the letter represents its viscosity at high temperatures.
Torque
When changing the oil, make sure that you tighten the oil plug strictly with the necessary torque. If you screw it in too loosely, the oil may simply leak out, or if you apply too much force, you risk damaging the threads.
31 lb-ft
Coolant capacity
Lack of coolant in the system can lead to engine overheating, which in turn leads to costly repairs. Ensure that the coolant amount is always at the level specified in the manual.

2.4L H-4
Horsepower
This is the main indicator of the car's power. The higher the number of horsepowers, the faster the car is able to accelerate.
230 hp
Torque
Engine torque is a measure of the twisting force that an engine produces at its crankshaft. It is a key factor in determining an engine's power output, as well as its ability to accelerate and tow heavy loads.
185 lb-ft.
Oil capacity
Keep an eye on the oil level in the engine. If it is too low, it can cause a breakdown, because all its elements must be abundantly lubricated during the operation. If it is too much oil, it will interfere with normal engine operation and create excessive resistance.
