Has 97 Octane Gasoline Been Discontinued?
2 Answers
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.
