What is 97 gasoline called now?
3 Answers
97 gasoline is now called 95 gasoline. Modification of gasoline grades: In the two local standards of "Motor Gasoline" and "Motor Diesel", the major change is that the gasoline grades have been modified from 90, 93, and 97 to 89, 92, and 95. Therefore, the previous 97 corresponds to the current 95. Usage of gasoline grades: The level of gasoline grades only indicates the size of the octane number of gasoline, and different grades of gasoline should be selected according to the different compression ratios of the engine. Medium-grade cars with a compression ratio between 8.5 and 9.5 should generally use 93 gasoline; cars with a compression ratio greater than 9.5 should use 97 gasoline. Nowadays, domestic cars generally have a compression ratio above 9, so it is best to use 93 or 97 gasoline.
I've been driving for many years and still remember seeing the signs for 97-octane gasoline at old gas stations. Nowadays, they've mostly been replaced with 92, 95, and 98 octane. To be honest, the old 97-octane corresponds to today's 95-octane because the national octane rating standard has been upgraded to be more scientific and unified. This change mainly reflects improved fuel quality—similar octane levels but cleaner, with more complete combustion, resulting in smoother engine response and reduced emissions, making it more environmentally friendly. Since I switched cars, I've been using 95-octane and haven't noticed much difference from the old 97-octane. The transition was smooth for my old car too, with no engine issues. My advice to new drivers is not to overthink the octane names—just follow the car manual's recommendation. Gas stations clearly display prices, and 95-octane offers good value for money, being both economical and reliable. Overall, adapting to the new standards brings many benefits.
As a young driver who just got my license, I was initially confused when I first heard about 97-octane gasoline. My friend told me it's now called 95-octane. After checking, I learned that the octane rating system has been improved. The old 97-octane corresponds to the new 95-octane, which offers more stable and cleaner fuel, suitable for most family cars. For daily driving in my small car, 95-octane is sufficient, unlike the chaotic fuel station practices in the past. The change is good—from an environmental perspective, reducing carbon emissions helps urban air quality; in terms of price, 95-octane is cheaper than 98-octane, making it a worry-free choice. In car enthusiast circles, the consensus is not to worry too much about compatibility, as new car manuals provide clear guidance. Remember, when choosing fuel, follow the standards and don’t guess—that’s the safe way.
