Can the Mercedes-Benz GLK300 use 92-octane gasoline?

[KaiRose]

Mercedes-Benz GLK300 cannot use 92-octane gasoline. There are many differences between the two types of gasoline, and using the wrong one can have consequences. Differences between the two types of gasoline: There is no fundamental difference in purity or quality between them. However, 95-octane gasoline contains 95% isooctane and 5% n-heptane, while 92-octane gasoline contains 92% isooctane and 8% n-heptane. N-heptane acts like a stimulant, while isooctane acts like a sedative. The higher the stimulant content, the slightly less stable the gasoline becomes, making it more prone to detonation. Conversely, the higher the isooctane content, the more stable the gasoline. Effects of using the wrong gasoline: Under the same compression conditions, 92-octane gasoline is more prone to premature combustion than 95-octane gasoline. For vehicles with high compression ratios that require 95-octane gasoline, using 92-octane gasoline may cause the fuel to ignite before the intended spark timing during engine operation. If a vehicle requires higher-octane gasoline but is filled with lower-octane gasoline, it can lead to premature combustion and engine knocking. In severe cases, this may cause damage to the engine.
