Should the Lexus NX300h use 92 or 95 octane gasoline?

[StEverett]

Lexus NX300h uses 92 octane gasoline. According to the manual's gasoline type requirements: Simply refuel with the specified 92 octane as required in the manual. There is no need to deliberately use higher octane gasoline, and it is even more important not to use fuel with a lower octane rating than required. The gasoline octane rating represents its anti-knock performance, with a higher number indicating better anti-knock capability. Introduction to the composition of 92 and 95 octane gasoline: 92 octane gasoline consists of 92% isooctane and 8% n-heptane, while 95 octane gasoline is composed of 95% isooctane and 5% n-heptane. The slightly higher cost of 95 octane gasoline is due to the larger proportion of isooctane.
