Has 97 Octane Gasoline Been Discontinued?

Due to the full implementation of the National V emission standards, as of January 1, 2017, the previous 90, 93, and 97 octane gasoline grades have been discontinued. Gas stations now only offer new grades: 89, 92, 95, and 98 octane. Below is more related information: 1. Reason for fuel upgrade: The implementation of new emission standards is primarily for environmental protection purposes. With stricter requirements on vehicle exhaust emissions under the new standards, upgrading fuel quality naturally leads to more environmentally friendly exhaust emissions. 2. Break-in period for older vehicles with new fuel: After the fuel upgrade, older vehicles using new fuel grades may experience a break-in period. For instance, if a vehicle previously used 97 octane, switching to the new 95 octane might cause the check engine light to illuminate.

I've also noticed that 97-octane gasoline is becoming harder to find when driving recently. Last year, many gas stations in my area stopped supplying it, saying they've upgraded to 98-octane or 95-octane fuel. This might be because modern car engines are more precise and require higher-octane gasoline to prevent knocking and improve combustion efficiency. As an average car owner, I was quite used to filling up with 97-octane before, but now using 98-octane doesn't make much difference, except for the slightly higher price. If you're still concerned, I recommend checking the recommended octane rating label on your fuel tank cap. Most modern cars are compatible with either 95 or 98-octane fuel without issues. Regularly using higher-quality fuel can also protect your engine and extend your car's lifespan. Before driving, pay attention to changes in nearby gas station signs, but remember that safe driving is the most important thing.

The upgrade in gasoline grades is a technical trend, with 97 octane being largely replaced by 98 octane in most regions of China, primarily to meet the requirements of the China VI emission standards. As engine compression ratios continue to rise, higher-octane gasoline is needed to prevent knocking and optimize performance. I've noticed that at repair shops, car owners often discuss this change—simply put, using 98 octane is cleaner and more efficient, reducing pollutant emissions. If your car originally used 97 octane, you can safely switch to 95 or 98 octane now. Just remember to adjust according to the recommendations in the owner's manual, and don't worry about compatibility issues. Price fluctuations are normal, but upgrading your fuel grade offers significant long-term benefits for protecting your vehicle's performance.

For environmental considerations, the phase-out of 97-octane gasoline is actually a great initiative. The government is promoting the replacement with higher-octane gasoline to reduce exhaust pollution. Using 98-octane fuel better complies with environmental standards and reduces harmful particulate matter in the air. Eco-conscious car owners like me support this change. Although refueling might be inconvenient at first, it benefits our health in the long run. Adapting isn't difficult either—just check your vehicle manual and local gas station announcements to ensure safe refueling.

In daily driving, the discontinuation of 97-octane gasoline has forced me to change my habits. Previously, I could just fill up casually and hit the road, but now I have to search more for 98-octane or 95-octane gas stations. This is common with policy-driven upgrades in automotive fuels, but the impact is minimal as new vehicles are designed to be compatible with higher-grade fuels. It's advisable to regularly check tire pressure and fuel quality to avoid engine issues. Just maintain a relaxed attitude—driving remains just as convenient and comfortable.

From an industry perspective, the phasing out of 97-octane gasoline is an inevitable outcome of fuel standard evolution, with more alternatives like ethanol-blended gasoline expected in the future. Vehicle owners need to adapt to this trend and recognize the benefits brought by environmental protection and technological advancements. A straightforward approach is to stay informed through official channels, select the appropriate fuel grade, and ensure smooth vehicle operation.
