What is the normal fuel consumption per 100 kilometers for the BMW N20 engine?
2 Answers
The comprehensive fuel consumption per 100 kilometers for the BMW N20 engine is considered normal between 6 to 8 liters. Method for calculating fuel consumption: Car fuel consumption is calculated by dividing the amount of fuel added by the distance traveled. For example, if you drive 100 kilometers and add 7.3 liters of fuel, the fuel consumption per 100 kilometers is 7.3 liters. Another example: when the fuel warning light comes on, you go to the gas station and add 30 liters of fuel, and the odometer shows 450 kilometers; then divide 30 by 4.5 to get 6.66, which is the fuel consumption per 100 kilometers. Fuel-saving tips: When driving in the city, traffic jams are common, so experienced drivers often plan their routes in advance to avoid congested areas. Reducing frequent starts and stops and maintaining an economical speed is equivalent to saving fuel.
I've been driving a BMW 328i with an N20 engine for over two years. The fuel consumption is around 9 liters per 100 kilometers for city commuting, which is normal, and it can drop to about 7 liters on the highway. There are quite a few influencing factors: driving gently and avoiding flooring the accelerator; better fuel efficiency when road conditions are good; regular maintenance like changing the air filter and spark plugs; and slightly higher consumption when using the AC in summer. Generally, 8 to 10 liters is acceptable, but if it exceeds 11 liters, you should check for clogged fuel lines or a faulty oxygen sensor. Also, remember to check tire pressure regularly—low pressure increases friction and leads to higher fuel consumption. Paying attention to these small details can help avoid extra costs.
