Generally, small cars require about 4L of engine oil, as long as the oil level on the dipstick is between the minimum and maximum marks. Below is relevant information: 1. As a type of machinery, engines share common requirements for lubricating oil with general machinery, such as appropriate viscosity, certain anti-oxidation, anti-wear, anti-corrosion, and viscosity-temperature performance requirements. However, engines are also a special type of machinery, and their requirements for lubricating oil have unique aspects. 2. Automotive engines operate in complex environments with significant variations in temperature, humidity, atmospheric pressure, and dust. Additionally, engine oil often contains elements like sulfur and lead, which can accelerate corrosion and wear on certain components.

To be honest, I've been driving 1.5L displacement cars for over a decade, like the Honda Civic or Toyota Corolla, with fuel tanks typically around 45 liters. I usually fill up to about 80% capacity, roughly 36 liters, leaving some space for fuel vapor to prevent overflow on hot days. Think about it - filling it completely might dirty the chassis and waste money. Tank sizes vary by model, starting from 40L for compact cars up to 50L for midsize vehicles. For fuel consumption, averaging 8L per 100km means a full tank can last over 500km on highways. But don't always fill up completely for daily driving - adjust based on your driving habits. A fuel-saving tip is to regularly maintain tire pressure and keep the engine efficient.

As an eco-conscious car owner, I've been driving a 1.5L displacement vehicle for years, emphasizing fuel efficiency. My urban commuting fuel consumption is about 9L/100km. With a typical 45L fuel tank, I usually refuel around 25L per week, which is just right. Avoid filling up too much at once - leaving space prevents expansion issues and saves resources. Choosing the appropriate gasoline grade like 92 octane saves money and reduces exhaust pollution. Here's an estimate: driving 1,200km monthly requires about 100L of fuel, and splitting this into 3-4 refuels is more economical. Combining short trips with walking helps reduce fuel consumption. Routine maintenance like cleaning air filters also improves fuel efficiency, killing multiple birds with one stone.

Driving a 1.5L displacement car for decades has taught me that fuel tank sizes vary between 40 to 50 liters. Don't fill it up completely; 80% is sufficient to prevent fuel expansion. Fuel consumption depends on conditions: city driving often reaches 10L/100km, while on highways it drops below 7L—drive slower to save fuel. Refuel according to distance; for short trips, just a dozen liters per fill-up is enough, saving money and ensuring safety.
