New cars are typically filled with about 5L to 8L of fuel, which is sufficient to allow the owner to drive to a nearby gas station after taking delivery. Here are some precautions for refueling a car: Avoid filling the tank completely: When driving in the city, there is no need to fill the fuel tank to the brim. Frequent stops in urban driving can increase the engine load if the tank is full. It is recommended not to fill beyond two-thirds of the tank capacity, as overfilling can cause fuel to overflow. Excess fuel may flow into the intake manifold, leading to spark plug "flooding," which can cause the engine to stall when refueling. In severe cases, the car may fail to start normally, and fuel may even leak from the carbon canister, posing a significant fire hazard if exposed to open flames. Do not wait until the tank is empty to refuel: The fuel pump in the tank relies on fuel for cooling. If the fuel level is too low and does not cover the pump, prolonged operation in this state may reduce the pump's lifespan. While this is less of an issue in winter, the risk is higher during the hotter summer months. Additionally, if the fuel level is too low, the pump may draw in sediment from the bottom of the tank, potentially clogging the pump or blocking the fuel line.

Last week I just picked up a new car and found the 4S store only filled the fuel tank halfway, which is roughly enough for about 30 kilometers. The salesperson said this is an industry practice, mainly for cost control considerations—they deliver dozens of cars daily, and filling up completely would increase monthly fuel expenses by tens of thousands. Additionally, gasoline in new cars stored in warehouses may deteriorate, so adding less fuel is actually better for the engine. I suggest not test driving the car on the pickup day but instead navigating directly to the nearest gas station. Make sure not to turn off the engine midway to avoid damaging the fuel pump due to low fuel levels. Remember to check the gas station location in advance—new car owners most commonly underestimate fuel consumption.

Having worked in the automotive industry for over a decade, I can definitively tell you that new cars typically come with no more than one-third of a tank of fuel. Manufacturers transport vehicles with empty fuel tanks, and dealerships only add a symbolic 5-8 liters before delivery—just enough to reach a gas station. Once while inspecting a new car for a client, the fuel gauge showed only 15 km of range, startling them into even avoiding using the AC. This design is quite sensible: it prevents fuel oxidation in inventory vehicles and deters employees from misusing company cars. When taking delivery, check if the low-fuel warning light is on. If the fuel level can't even last two kilometers, it's advisable to request the salesperson to top it up on the spot.

Yesterday, I accompanied my friend to pick up an SUV, and the 4S store only added 3 liters of fuel, just enough to drive to the gas station 500 meters away. Salesperson Xiao Wang privately mentioned that their fuel cost per vehicle is controlled within 50 yuan, so popular models might only get 3 liters, while slow-selling models could receive up to 10 liters to facilitate delivery. Before refueling, remember to check if the fuel tank cap is tightly secured. Last year, there was news about a new leaking fuel because the fuel filler cap wasn't properly closed. It's recommended for beginners to download a fuel app on their phone in advance; the first order might even offer a 20-yuan discount. Also, take the opportunity to check if the tire pressure is normal.

As a car enthusiast, I've noticed significant differences in fuel quantities provided by different brands. Japanese cars usually offer 5-7 liters, German cars typically provide 3-5 liters, while domestic new energy vehicle startups are surprisingly the most generous - NIO's swap models don't provide any fuel at all. Once I forgot to refuel when driving a new car and broke down halfway, costing me 300 yuan for towing. Now I've developed a habit: check the fuel gauge range when picking up a car, and if it's below 20 km, immediately navigate to the nearest gas station on my phone - no air conditioning or music during the trip. For the first two fuel fills in a new car, it's best to use 95-octane gasoline as it's more engine-friendly during the break-in period.

When I first got my driver's license and picked up the car, the 4S dealership only added a thin layer of base fuel, letting me drive off with the fuel warning light on. Master mechanic Lao Zhang told me that fueling a new car is like the seasoning packet in instant noodles—just the bare minimum. Now when helping relatives inspect cars, I always bring a portable fuel can, keeping two liters of emergency fuel in the trunk. Note: For the first refuel, add the manufacturer's fuel additive to remove trace iron particles from transport. It's advisable for new car owners to request a written guarantee from the salesperson specifying the minimum fuel quantity to avoid disputes.
