Can the new Sagitar use 92-octane gasoline?

The new Sagitar can use 92-octane gasoline. Here is some relevant information about 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 allowed is 92-octane. 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 a vehicle has been using 92-octane gasoline, it can be mixed with 95-octane gasoline, though the anti-knock performance will differ. In other words, lower-octane gasoline can be mixed with higher-octane gasoline, but vehicles that have been using 95-octane gasoline should not mix it with 92-octane gasoline. Higher-octane gasoline should not be mixed with lower-octane gasoline, except in emergencies where temporary mixing is acceptable. After mixing, a fuel additive can be used for cleaning.
I've been driving my Sagitar for over three years, and the manual clearly states that it's recommended to use 95-octane fuel. However, once during a long trip when I couldn't find 95-octane, I filled half a tank with 92-octane as an emergency measure and didn't notice any abnormalities while driving. But if you use 92-octane fuel for a long time, the fuel's anti-knock performance is insufficient, which can easily cause knocking. The engine malfunction indicator light might come on, especially when climbing hills with the air conditioning on in summer—you might hear clunking sounds from the chassis. Turbocharged cars have high compression ratios, so it's best to follow the manufacturer's recommended fuel grade. After all, repairing a high-pressure fuel pump once could cost as much as three years' worth of 95-octane fuel.
