More engine specs 
Engine is relatively reliable. Most problems relate to the fuel injection system, spark plugs  ...  This BMW 3 series 3.0 engine oil type is 5W-30 and oil capacity is 6.5 litres.

BMW 325i 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 accelerates to speed 100 kilometres per hour in 7.6 seconds. The maximum speed of this car is 244 km/h.

BMW 325i fuel consumption is 8.2 litres per 100km in combined city/highway mode (12.2 km/l), city fuel economy - 11.1 l/100km, fuel consumption on highway - 6.5 l/100km. Fuel tank capacity is 61 litres or 16.12 gallons, which gives a mileage up to 740 kilometers without refueling in urban cycle and even up to 920 kilometers on highway.
According to user reviews, this BMW real everyday fuel consumption is 9.9 litres per 100 km, which is 21% more than the manufacturer's stated. More - Real BMW 3 series fuel consumption.

With the same engine there are also three other BMW 3 series versions - with rear wheel drive and manual gearbox (BMW 325i MT), and with rear wheel drive and automatic gearbox (BMW 325i AT), and with manual gearbox (BMW 325i MT 4x4) available:
  • BMW 325i MT is more dynamic - it reaches 100 km/h 0.9 seconds faster (in 6.7 seconds), moreover, it is more economic with manufacturer's fuel consumption is lower by 1 litres per 100 km or 12 % - 7.2 litres per 100 km, whereas users reported real fuel consumption is lower by 1.2 litres per 100 km or 12 % - 8.7 litres per 100 km
  • BMW 325i AT is more dynamic - it reaches 100 km/h 0.5 seconds faster (in 7.1 seconds), but manufacturer's fuel consumption is lower by 0.8 litres per 100 km or 10 % - 7.4 litres per 100 km, whereas users reported real fuel consumption is similar - 9.9 litres per 100 km
  • BMW 325i MT 4x4 is more dynamic - it reaches 100 km/h 0.4 seconds faster (in 7.2 seconds), but manufacturer's fuel consumption is similar - 8.1 litres per 100 km, whereas users reported real fuel consumption is similar - 9.9 litres per 100 km

Engine reliability and common problems:

Engine is relatively reliable. Most problems relate to the fuel injection system, spark plugs and coils, and the Vanos phase control system. Problems with the high pressure fuel pump were common in early model years. Otherwise the engine is considered to be of fair quality and reliability.
Overall, this engine can last around 270,000 to 450,000 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 2996 cm3
Number of cylinders 6
Bore (cylinder diameter) 85 mm
Stroke length (piston move) 88 mm
Compression ratio 12 : 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.
