BMW 120i Engine Problems

The B4820 two-litre four-cylinder engine in BMW's current F20-generation 120i uses a timing chain.

The current F20-series BMW 120i is rated on a combined cycle as using 5.9-litres of unleaded fuel per-100km. While it isn't as good as other small hatchbacks in the class it would still be considered good fuel consumption, especially given most large family cars would consume 10-12-litres per-100km.

BMW's F20-series 120i runs a timing chain on the B48B20 two-litre four-cylinder engine.

The official fuel consumption figures for BMW's 120i on a combined cycle is 5.8L per-100km driven.

I would certainly consider this good consumption as many large cars use nearly twice as much fuel per-100km.
