Is There 93 Octane Gasoline?
2 Answers
There is no 93 octane gasoline. Starting from the National V gasoline standard, 93 octane gasoline has been replaced by 92 octane gasoline, which requires an octane rating of no less than 92. This change was made during the upgrade to the National V gasoline standard, which imposed stricter environmental requirements, such as lower levels of sulfur, olefins, aromatics, benzene, and other substances. The selection of gasoline for a car should be based on the engine's compression ratio. Using the appropriate gasoline ensures better vehicle performance. Therefore, regardless of the type of car you drive, you should always follow the fuel requirements specified in the vehicle's manual. There is no need to use gasoline with a higher or lower octane rating than recommended. There are several types of gasoline, each with different component ratios, which affects their performance. Always check the octane rating before refueling, and ensure the engine is turned off when filling up. Staff at gas stations will also remind you to turn off the engine when you arrive. Refueling Tips: While driving, always monitor the fuel gauge. When the gauge shows only a quarter of the tank remaining, it's time to refuel. Avoid waiting until the fuel warning light comes on. Modern cars use electric fuel pumps that rely on gasoline for lubrication and cooling. Frequently waiting until the fuel light comes on can reduce the fuel pump's lubrication and cooling, shortening its lifespan. Additionally, if the fuel tank remains empty for too long, the temperature difference inside and outside the tank can cause moisture buildup, leading to tank corrosion, degraded fuel quality, and increased engine strain.
In my recent research on gasoline octane ratings, I found that 93-octane gasoline is available in some regions, such as certain states in North America like California or Florida, where it is typically sold as a high-octane option, roughly equivalent to the European 95-octane standard. The octane level affects engine knocking issues: the higher the value, the better the anti-knock performance, making it suitable for performance cars or turbocharged models. Using lower-octane fuel may cause engine vibrations or increased fuel consumption. However, global standards vary. In China, 89, 92, and 95-octane are common, while 93-octane is less mainstream. I recommend checking your local gas station app or website for availability. If unavailable, opting for 95-octane might be safer and won't harm modern engines. I always check the vehicle manual's recommended rating before refueling to avoid unnecessary repair costs, especially before long trips.
