Should private cars generally use 92 or 95 octane gasoline?

[GriffinMarie]

Private cars should choose between 92 or 95 octane gasoline based on the fuel grade indicated on the vehicle's fuel tank. Cars requiring 92 octane should use 92 gasoline, while those requiring 95 octane should use 95 gasoline. Below is an introduction about private cars: 1. Introduction: A private car refers to a vehicle purchased and owned by an individual, who has the right to use and control it freely as long as it is within legal boundaries. 2. Regulations: In 2013, the previous regulation requiring private cars to be scrapped after 15 years was abolished, replaced by a guideline for scrapping after 600,000 kilometers. 3. Development: Starting from September 1, 2014, a trial exemption from inspection was implemented for non-commercial passenger cars and other small and micro passenger vehicles (excluding vans and vehicles with 7 or more seats) that are within 6 years of use.
