On this engine, the valve seals and crankcase breather valve diaphragm tend to fail after  ...  This BMW 3 series 2.5 engine oil type is 5W-30 and oil capacity is 6.5 litres.

BMW 325i xDrive Touring has AWD (all wheel drive) (power is automatically distributed between the wheel axles) and automatic gearbox with 6 gears. BMW xDrive is a proactive all-wheel drive system without a center differential that engages before the vehicle becomes destabilized, unnoticed by the driver. Torque is distributed between the axles by an electronically controlled multi-plate clutch in the transfer case. The clutch is partially locked most of the time, distributing power to both axles in a 40/60 front/rear ratio, but the system is capable of sending 100% of the torque to either axle. At high speeds or when parking, for example, the clutch is disengaged and all power is sent to the rear wheels. DSC (Dynamic Stability Control) also brakes the wheels individually to regain traction and assist in cornering.
BMW 325i xDrive Touring accelerates to speed 100 kilometres per hour in 8.1 seconds. The maximum speed of this car is 240 km/h.

The fuel consumption of this BMW 325i xDrive Touring in combined mode (combining urban and highway driving) is 8 litres per 100km (12.5 km/l), city fuel economy - 10.9 l/100km, fuel consumption on highway - 6.3 l/100km. Fuel tank capacity is 63 litres or 16.64 gallons, which gives a mileage up to 780 kilometers without refueling in urban cycle and even up to 1000 kilometers on highway.
According to user reviews, this BMW real everyday fuel consumption is 10.3 litres per 100 km, which is 29% more than the manufacturer's stated. More - Real BMW 3 series fuel consumption.

Engine reliability and common problems:

On this engine, the valve seals and crankcase breather valve diaphragm tend to fail after 80-100 000 km, leading to increased oil consumption. It is recommended to choose engines manufactured in the last years of production (after 2010). The engine is not suitable for power boost modifications.
Overall, this engine can last around 220,000 to 370,000 km if properly maintained, using the correct quality oil and fuel, and carrying out regular checks and maintenance.
The engine has hydraulic valve tappets (lifters), which provide quieter operation and do not require periodic adjustment, but are more complex in design and can cause serious engine damage in the event of failure.
Engine displacement 2497 cm3
Number of cylinders 6
Bore (cylinder diameter) 82 mm
Stroke length (piston move) 78.8 mm
Compression ratio 11 : 1
Camshaft drive Timing chain

Chain motors are considered more reliable, chain replacement usually is required less often than a timing belt, but they are often louder and vibrate more.

More service info
Timing chain change interval 120,000 km (recommended)

Sometimes manufacturers do not specify timing chain replacement intervals and design chains for engine life. However, once the recommended change interval has been reached, it is recommended to periodically check the condition of the chain and to change the chain if excessive stretching is detected or if unusual noises from the engine or other symptoms occur.
