Is the fuel quality at Jingbiao gas stations good?

The fuel quality at Jingbiao gas stations is good. Jingbiao is a local standard, while the national standard is a country-wide regulation. In terms of standard hierarchy, the national standard is generally set more broadly to account for regional differences across the country, whereas local standards are more tailored and stricter to meet regional requirements. Due to Beijing's high environmental protection standards, the fuel quality under the Jingbiao standard is among the highest in the nation. Below is an introduction to 92 and 95 octane gasoline: 1. 92 octane gasoline: Contains 92% isooctane and 8% n-heptane. 2. 95 octane gasoline: Contains 95% isooctane and 5% n-heptane. When the pistons move inside the engine cylinders, gasoline and air mix and compress. If the pressure becomes too high, knocking may occur.
I've been using fuel from Jingbiao gas stations, and I must say the quality is really good. I used to use other brands of fuel, and the engine would always shake a bit when the air conditioning was on, but after switching to Jingbiao, it became much smoother. Jingbiao's fuel follows Beijing's local standards, which are stricter than the national standards, especially in terms of sulfur content being particularly low. This results in cleaner exhaust, which is also better for the catalytic converter. Once, I took apart the engine and saw that after running 80,000 kilometers with Jingbiao fuel, the intake valves had almost no carbon buildup, and cold starts were quicker. Although it's a few cents more expensive than regular gas stations, considering the savings on engine maintenance and part replacements, it actually saves money in the long run. I recommend choosing larger Jingbiao stations for fresher and more reliable fuel.
