Maintenance outside 4S shops does not affect the warranty. Here are the maintenance precautions: 1. Choice of maintenance location: According to Article 9 of the Consumer Rights Protection Law: Consumers have the right to independently choose goods or services, and as car owners, they also have the right to choose vehicle maintenance operators. 2. Precautions for external maintenance: As consumers, they can freely choose repair shops for maintenance. As long as the vehicle damage is not caused by maintenance reasons, they can normally enjoy the warranty. If consumers fail to use, maintain, or repair the product correctly according to the instruction manual, resulting in damage, the operator is not responsible for the three guarantees. In other words, except for the maintenance location, other requirements cannot be changed.

I've been driving the 2021 Sylphy for almost two years now, and what satisfies me most about this car is its fuel efficiency. During rush hour commutes in the city with constant stop-and-go traffic, the fuel consumption stays around 7.5 liters per 100 km. It's especially fuel-efficient on highways - when cruising at 100 km/h, the dashboard shows only 4.8 liters. Using air conditioning doesn't affect consumption much, even during the hottest summer days it's just slightly over 8 liters. With its 47-liter fuel tank, a full tank can last over 600 km in city driving and nearly 1,000 km on highways. Remember to check tire pressure regularly and maintain it around 2.4 bar, which helps reduce fuel consumption. Long-term usage shows monthly fuel costs of just 600-700 yuan, much more economical than my colleagues' German cars.

The 2021 Sylphy is equipped with a 1.6L engine paired with a CVT transmission, designed with fuel efficiency in mind. The official claimed fuel consumption is 4.9L/100km, but actual driving conditions significantly affect this figure. In urban areas with frequent traffic lights, consumption can rise to over 7L, while on suburban expressways, it stabilizes around 5.5L. The vehicle benefits from good lightweight construction and a low drag coefficient, both contributing to fuel savings. For optimal economy, it's recommended to avoid aggressive acceleration and keep the RPM below 2000 during daily driving. Regular maintenance, including using low-viscosity full synthetic oil and keeping the air filter clean, helps maintain stable fuel consumption. Also, ensure the fuel tank cap is tightly secured to prevent fuel vapor leakage, which can lead to unnecessary fuel wastage.

Based on current fuel prices, the Nissan Sylphy consumes 6.5 liters per 100 kilometers. Driving 15,000 kilometers a year would cost around 8,000 yuan in fuel, with monthly expenses of six to seven hundred yuan. This saves over a thousand yuan annually compared to some American cars in the same price range. Maintenance costs are also low, with minor services costing just 300 yuan. The car has high resale value, losing less when sold after three years. Its advantage is even more pronounced when fuel prices rise, as a full tank saves nearly 100 yuan compared to SUVs. For daily commuting, avoiding peak traffic hours and choosing highway routes for weekend trips can significantly reduce expenses.
