Can China VI Diesel Vehicles Use Non-branded Fuel?
2 Answers
China VI vehicles do not require special gasoline, but it is advisable to avoid refueling at small gas stations to prevent the use of poor-quality fuel. For China VI vehicles, low-ash engine oil should be the preferred choice as it contains minimal ash content, significantly reducing the likelihood of particulate filter clogging. The reasons for not recommending non-branded fuel are as follows: 1. Unreliable fuel quality: Small gas stations, due to inferior storage and filtration technologies compared to major brands, often sell gasoline with many impurities. These impurities can clog the vehicle's fuel injection system, causing significant damage. 2. Unknown fuel sources: The fuel at small gas stations mainly 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 fuel quality is hardly guaranteed.
As someone who frequently studies automotive emission systems, I firmly believe that China VI diesel vehicles must never use 'small oil'. The so-called 'small oil' refers to inferior diesel sold by roadside vendors, which contains excessive impurities and high sulfur content. The China VI standard imposes extremely stringent emission requirements, and these vehicles are equipped with DPF and SCR systems to treat exhaust gases. If you use 'small oil', the impurities can clog the injectors, damage the DPF filter, cause engine vibration, reduce power output, and even lead to emission violations resulting in fines. I've heard many car owners tried it to save money, only to spend thousands of yuan later on injector repairs. While Sinopec's certified diesel may cost slightly more, it protects engine longevity and ensures compliance—ultimately proving more cost-effective in the long run. Developing good driving habits is crucial; saving small amounts of money isn't worth inviting big troubles.
