Should the Reiz use 92 or 95 gasoline?

[SebastianLee]

The Reiz can use 92-octane gasoline. Below are the reasons for choosing 92-octane gasoline: 1. Generally, the octane rating indicated for a car is the minimum safe rating for combustion. For example, if it is recommended to use gasoline with an octane rating of 92 or higher, it means the minimum allowable rating is 92. However, the minimum rating is not necessarily the most efficient for combustion. 92-octane gasoline has a much lower proportion of isooctane compared to 95-octane gasoline. The higher the octane rating, the higher the isooctane value. A higher proportion of isooctane means better anti-knock performance for the gasoline. 2. If the vehicle has been using 92-octane gasoline, it can be mixed with 95-octane gasoline, as they only differ in anti-knock performance. In other words, lower-octane gasoline can be mixed with higher-octane gasoline, but gasoline with a higher octane rating (e.g., 95) should not be mixed with lower-octane gasoline (e.g., 92). That is, higher-octane gasoline should not be mixed with lower-octane gasoline, except in emergencies where temporary mixing is acceptable. After mixing, fuel additives can be used for cleaning.
