Can a Car Rated for 92 Octane Use 95 Octane?
1 Answers
A car rated for 92 octane can use 95 octane, but long-term use may cause damage to the vehicle. During the development and matching of the engine, manufacturers conduct tests, adjustments, and road trials, so it is recommended to use the gasoline grade specified by the manufacturer for the vehicle model. Gasoline is a mixture, and the octane rating commonly referred to indicates the anti-knock index or octane number. Strictly speaking, 92 octane and 95 octane gasoline should not be mixed. However, since their chemical compositions and other aspects are relatively similar and both have strong anti-knock properties, mixing them generally does not cause significant issues. Nonetheless, to ensure vehicle safety, it is best to use them separately.
