Does filling up at different gas stations affect the car?

Filling up at different gas stations does not affect the car. Here is some information about car refueling: 1. The optimal amount of fuel to add: It's best to fill up about three-quarters of the tank. This is a moderate amount for both the fuel and the car's working condition. When the tank is overfilled and the fuel cap is not tightly sealed, there can be some safety hazards, although this is only a small probability. Also, you shouldn't wait until the tank is completely empty to refuel, as this can damage the components in the car's fuel supply system. 2. Precautions when refueling: Do not smoke or make phone calls at the gas station, do not mix different grades of gasoline, and do not wait until the tank is almost empty to refuel.

Does switching gas stations affect your car? Having run an auto repair shop for years, I've seen many cases. In reality, fuel quality varies significantly—stations source from different refineries, and additive packages differ. Major brands like Sinopec use detergents that reduce engine carbon buildup, while cheaper independent stations may skimp on additives. Long-term use of subpar fuel can cause sluggish acceleration, poor mileage, and even trigger check engine lights. Pay attention to octane ratings too—using lower-grade fuel than required may cause engine knocking. I recommend following your owner's manual specifications, changing oil regularly to filter contaminants, and avoiding constant station-hopping. Many drivers chase fuel savings only to incur heavier repair costs—a false economy. Always check for certification logos to ensure station legitimacy; your engine deserves quality fuel to run smoothly.

I've been driving for over a decade and often refuel at different gas stations, such as PetroChina in the city and small stations during trips, without encountering major issues. Sometimes cheaper fuel might cause the car to start a bit slower or make refueling feel less smooth, mainly due to different additive packages, with big-brand fuels offering better cleaning performance. However, occasionally switching fuels in the short term is generally safe, as cars are designed to handle such differences and won't break down immediately. The key is to observe the fuel's color and smell—clear and transparent is standard, while cloudy or odd-smelling fuel should be avoided. To save money, I sometimes refuel at discount stations. If the car is new, it's advisable to stick to one station to build some loyalty, while older cars can be more flexible. Price and convenience are important, but don't compromise by using low-quality fuel that could damage the engine. Regularly driving at high speeds can also help clean carbon deposits and keep the car healthy.

Different gas station fuels pose risks to vehicles. I've encountered cases where owners experienced engine shaking and black smoke after using low-quality fuel. Variations in fuel quality stem from refining processes; reduced additives can accelerate carbon deposit buildup, leading to cylinder wear over time and costly repairs. Substandard fuel may also contain water or impurities, clogging fuel injectors. When choosing gas stations, prioritize reputable ones—look for certified major brands for reliability and avoid small, obscure stations to prevent issues. Long-term effects are significant, especially for performance cars or turbocharged engines which are more sensitive. Conduct regular engine diagnostic checks and address problems early—don't wait for warning lights.
