Are turbocharged models more fuel efficient?
If we take "fuel economy" as a fuel-saving concept, and the ability of a car to drive economically with as little fuel consumption as possible under the condition of ensuring power, then overall, compared with a naturally aspirated engine, the turbo increases Compression technology can help gasoline engines increase fuel economy by 20%, diesel engines increase fuel economy by 40%, and can provide the same or even better power performance as the large engines they replace.
If the actual power output, that is, the power point of view, the power of a 1.5T engine is equivalent to the power of a 2.0L naturally aspirated engine, and the fuel consumption of 1.5T is definitely much lower than that of a 2.0L engine. According to the data of Baojun 560, the fuel consumption per 100 kilometers of 1.5T reaches 6.8L, so it is not reliable to say that the turbocharged engine costs fuel.
Do turbocharged models have higher oil requirements?
There is no need to worry about this at all. The turbocharger does not require a special oil for maintenance, as long as you choose a quality-guaranteed oil according to the maintenance manual required by the vehicle manufacturer.
The maintenance cost of a turbocharged model is much higher than that of an ordinary model?
The turbocharger is a standard component of the engine system. It is routinely maintained together with engine maintenance. There is no problem of needing to maintain this component separately. To sum it up in one sentence, the turbocharger has the same life span as the engine. During the engine life cycle, there is no need for additional maintenance and replacement of the turbocharger.
