The Buick Excelle 1.5L, 1.6L, and 1.8L models require 4 liters of engine oil. The Buick Excelle 1.4T and 1.6T models require 4.5 liters of engine oil. More relevant information is as follows: 1. It is advisable to fill the engine oil to the midpoint between the upper and lower marks on the dipstick. Do not go below the midpoint, as high-speed driving can cause the engine to heat up, making the oil thinner. If the oil level is too low, it will reduce lubrication effectiveness. A little above the midpoint is acceptable, but do not exceed the upper mark on the dipstick. This can cause significant damage to the engine. 2. Excessive engine oil increases internal engine resistance, leading to higher fuel (gasoline) consumption. Too much oil raises internal oil pressure, putting extra strain on the engine's oil seals and piston rings. This can accelerate wear on the crankshaft and valve seals, potentially causing oil leaks. High pressure and excess oil can also prevent the piston rings from properly sealing the cylinder, allowing oil to enter the combustion chamber and leading to oil burning.

Speaking of the Buick Excelle's fuel tank, I have to say it typically holds around 45 liters, with variations depending on the specific model. For instance, newer models generally have a 44-liter capacity, while older versions might hold up to 50 liters. Based on my observations of different owners' feedback in parking lots, a full tank can last between 450 to 550 kilometers in city driving, depending on road conditions and speed. On the highway with smooth traffic, it can go even further. The fuel tank size is quite reasonably designed, minimizing frequent trips to the gas station. A friendly reminder: don’t wait until the fuel warning light comes on to refuel, as this can damage the fuel pump; filling up to 90% capacity is usually sufficient. For maintenance, regularly clean the area around the fuel tank cap to prevent debris from clogging and affecting performance. Overall, it’s quite convenient for daily commutes and trips.

I drive my Excelle to work every week, and its fuel tank has a capacity of 44 liters. A full tank can last over 500 kilometers. In the city, the fuel consumption is about 7L/100km. Filling up on weekends ensures enough fuel for the entire week, which is quite hassle-free. Highway trips are even more economical, with longer range and fewer stops. It's recommended to use 95-octane gasoline to protect the engine; also, avoid overfilling the tank to prevent pressure issues that could affect the car's condition. The fuel tank capacity is well-suited for city life, reducing the need for frequent gas station visits. Occasionally, during traffic jams, driving at a slower speed helps save fuel and extend the distance.

Having serviced many Excelle models, the fuel tank capacity is commonly around 45 liters. Owners often worry about how far they can drive after the low fuel warning light comes on, but it's actually a safety design with a 10-15 km buffer reserve. Avoid overfilling beyond the marked limit to prevent damage to the charcoal canister. Always tighten the fuel cap properly to prevent gasoline evaporation or contaminants from entering. Ensure the fuel lines are not clogged, as this can lead to higher fuel consumption. With a moderate capacity, it has fewer faults and simple maintenance.
