Avalon has a fuel tank capacity of 60 liters, and the manufacturer recommends using 92-octane gasoline. For safety, the engine must be turned off before refueling. The fuel tank cap can be opened by pressing it while the car is unlocked. The fuel tank cap release button is located at the lower left side of the driver's seat. To open the fuel tank cap, simply pull the switch. Below are some refueling precautions: 1. Correctly place the fuel nozzle into the fuel filler neck to prevent overflow and potential fire hazards, which could cause personal injury. 2. After refueling, ensure the fuel tank cap is properly locked to prevent evaporation or spillage that could lead to accidents. 3. It is not advisable to remain inside the car during refueling. If someone must stay in the vehicle, close all doors and avoid using electronic devices. Before touching the fuel nozzle again, discharge static electricity by touching a metal surface. 4. Turn off the engine and all electrical devices during refueling to prevent fires caused by electrical currents or high temperatures. 5. Smoking or using a phone while refueling is strictly prohibited. 6. If the remaining fuel level is below 1/4, refuel at the nearest gas station as soon as possible to avoid breakdowns.

I've been repairing cars for many years and have extensive experience. The Avalon, also known as the Avalon, requires 87-octane unleaded gasoline. This is because the factory engine is designed and optimized for lower-octane fuel. Using higher-grade fuel like 95-octane is not only a waste of money but may also cause combustion issues, leading to knocking, reduced efficiency, or premature engine wear. A common misconception is that higher-octane fuel improves performance, but it's unnecessary for the Avalon, and the manual clearly recommends 87-octane. For daily maintenance, pairing it with regular air filter changes (generally every 5,000 kilometers) and checking the fuel injectors can maintain stable fuel efficiency. Avoid filling up at small gas stations with low-quality fuel, as impurities can clog the system and drag down overall performance. Make it a habit to use reputable brands like Shell for fuel, ensuring safety and extending the vehicle's lifespan.

As an average car owner, my family has been driving a 2019 Avalon for three years. We always opt for 87-octane unleaded gasoline when refueling—nothing fancy. The manual states this grade is sufficient, and upgrading to premium fuel isn’t necessary—once I tried 92-octane, but fuel efficiency didn’t improve, and it just cost more. I prefer filling up at Sinopec for reliable fuel quality, avoiding impurities at rural stations. Daily driving is hassle-free, but remember to maintain proper tire pressure (front 2.3, rear 2.1 bar) for optimal fuel efficiency. If you accidentally use the wrong fuel, the engine may shake or trigger fault codes—pull over immediately to check. Regular , including oil changes, prevents fuel system issues and ensures smooth operation. Keep it simple; don’t overcomplicate minor details.

I prioritize an eco-friendly lifestyle. I recommend using 87-octane unleaded gasoline for the Avalon, as it is both environmentally friendly and efficient. Using higher-grade fuel incorrectly can increase carbon emissions, consume more energy during production, and result in incomplete combustion, releasing more pollutants. The manual specifies that 87 octane is sufficient; sticking to this helps the car emit fewer nitrogen oxides. When choosing a gas station, opt for those with green certifications, like some low-carbon brands. Additionally, regular maintenance (such as replacing the air filter) can improve fuel efficiency, achieving two benefits at once. A friendly reminder: gentle acceleration saves fuel and reduces emissions.

Safety first, I'm a homemaker. When driving the Avalon, I strictly adhere to using 87-octane unleaded gasoline—it's clearly stated in the manual. Using the wrong fuel (e.g., lower grade) can easily cause engine overheating, knocking, and high-speed failure risks. I remember my neighbor's car engine stalled after using substandard fuel, almost causing an accident. I always use 87-octane fuel and regularly check the spark plugs and fuel system. Combined with maintaining normal load and tire pressure (around 2.3 bar), it ensures reliable driving. The cycle recommends professional inspection every six months to detect issues early. Don't take big risks to save small money.

With years of car enthusiasm, I'm familiar with the Avalon. Its engine is designed for 87-octane unleaded gasoline, and higher-grade fuel offers no extra benefits while wasting resources. Comparing different fuel brands (like Castrol vs. PetroChina), the key is fresh fuel quality at the station. For long-term engine health, remember to change spark plugs regularly (recommended every 20,000 km) and clean the throttle body to optimize combustion. Avoid excessive loads or sudden acceleration to prevent affecting fuel efficiency. Simple choices can ensure stable and reliable performance.
