Should the Pajero use 92 or 95 octane gasoline?

The Pajero can use 92 octane gasoline as specified in the manual, and there is also a reminder inside the fuel tank cap. Here is more information on gasoline selection: 1. The octane rating of 92 or 95 gasoline represents the fuel's anti-knock performance. The higher the octane number, the greater the isooctane content, indicating better anti-knock performance. Different engines require different anti-knock values. 2. For engines with a compression ratio greater than 9:1, it is recommended to use gasoline with an octane rating of 90 or higher. For engines with a compression ratio greater than 9.5:1, it is best to use 92 octane or higher. When the compression ratio exceeds 10:1, it is advisable to use 95 octane or higher. The compression ratio can be found in the specifications section of the manual.
I've been driving a Pajero for five years and always use 92-octane fuel. The engine's compression ratio isn't high, and the manufacturer's manual clearly states that 92-octane gasoline is acceptable. While 95-octane fuel has better anti-knock properties, our naturally aspirated engines don't really need it. However, if you frequently drive in high-altitude areas or use air conditioning while climbing steep hills in summer, you might notice slightly smoother throttle response with 95-octane. I've modified the chassis and often go off-road, so I always refuel at Sinopec or PetroChina stations - fuel quality matters more than the octane rating. Those recommendations to use higher-octane fuel are mostly just gas station sales tactics.
