Is the 2019 model V97 using 92 or 95 fuel?

As long as it's naturally aspirated, any gasoline will do.

The fourth-generation Pajero with the 6G75 engine has upgraded performance and typically requires 95 octane fuel. However, 92 octane can be used in emergencies.

Either is fine. Usually, it's 92. But if money's not an issue, 95 is also okay.
