What's the Difference Between Filling Up a China 6 Vehicle at Small Gas Stations?
2 Answers
China 6 vehicles should avoid refueling at small gas stations to prevent the use of poor-quality fuel. When selecting engine oil for China 6 vehicles, low-ash oil should be the first choice. This type of oil contains minimal ash content, significantly reducing the likelihood of particulate filter clogging. The main reasons to avoid gasoline from small gas stations are as follows: Unreliable Fuel Quality: Due to inferior storage and filtration technologies compared to major brand gas stations, the gasoline sold at small stations often contains many impurities. These impurities can clog the vehicle's fuel injection system, causing significant damage. Unknown Fuel Sources: The fuel at small gas stations primarily comes from local small-scale refineries. Some even mix gasoline from these small refineries with major brand gasoline, making it difficult to distinguish genuine from fake, and the quality of the gasoline is hard to guarantee.
When I drove my China VI emission standard vehicle and refueled at a small gas station, I noticed a completely different performance. China VI vehicles have more sophisticated emission systems with numerous sensors, making them extremely sensitive to fuel quality. The fuel from small stations tends to have unstable quality, possibly containing impurities or excessive sulfur content, which can suddenly trigger the engine warning light, cause sluggish acceleration, and sometimes emit black smoke. A friend of mine with a similar vehicle refueled at a small station once and ended up spending thousands to repair a clogged DPF system. I recommend only using fuel from major stations like Sinopec. Although it's more expensive, it protects your vehicle investment, saves you from repair hassles, and maintains smooth environmental performance.
