1.5t with 92 or 95?

[MacKatherine]

Most 1.5t turbocharged engines require at least 95 gasoline, but some car turbocharged engines can use 92 gasoline. If you are not sure what grade of gasoline your car's engine needs, it is recommended to check the fuel tank cap. The differences between 92 and 95 are as follows: 1. Different content: 92 gasoline is composed of 92% isooctane and 8% n-heptane, while 95 gasoline is composed of 95% isooctane and 5% n-heptane. 2. Different prices: A tank of 95 gasoline is slightly more expensive than 92 gasoline. 3. Different power: 95 gasoline with a higher octane number is suitable for engines with higher compression ratios. Because as the operating speed of such engines increases, the ignition timing in the cylinder will be advanced. As a result, when the speed reaches a critical point, the oil and gas in the cylinder will burn in advance before ignition, which is called knocking. Increasing the octane number of gasoline can effectively improve the anti-knock performance.
