Should the Corolla use 92 or 95 octane gasoline?
1 Answers
The Corolla is recommended to use unleaded gasoline with a specification of 92 octane or higher. Here is some extended information about gasoline: 1. 92 octane gasoline refers to gasoline with an octane rating of 92, suitable for mid-range vehicles (with lower compression ratios). 2. The gasoline octane rating represents its anti-knock properties; the higher the number, the better the anti-knock performance, but it does not indicate the quality of the gasoline itself. 3. The type of gasoline a car uses is related to the engine's compression ratio. A higher compression ratio results in greater power and efficiency but lower stability, requiring gasoline with higher anti-knock properties. If the compression ratio does not meet the requirement, using higher octane gasoline will not significantly improve performance, though it may offer slightly better cleaning and lower carbon emissions.
