Can I use 92 octane unleaded gasoline if the requirement is '92 octane or above'?

[LeTravis]

The '92 octane or above unleaded gasoline' requirement on the fuel tank cap includes 92 octane, and the vehicle user manual also provides detailed instructions in this regard, stating that at least 92 octane or higher gasoline should be used. Therefore, using 92 octane gasoline is acceptable. Unleaded gasoline contains only trace amounts of lead derived from crude oil, generally about 0.01 grams per liter. Its octane rating is 95, slightly lower than other grades of leaded gasoline currently available. Using unleaded gasoline can effectively control harmful substances in vehicle exhaust, reducing pollutants such as hydrocarbons, carbon monoxide, and nitrogen oxides. The most effective and simplest way to reduce emissions is to install a catalytic converter in the exhaust system. However, if the lead content in gasoline exceeds 0.013 grams per liter, the catalyst will become ineffective, failing to control vehicle exhaust emissions. Gasoline is categorized into leaded gasoline (phased out of the market), unleaded gasoline, and ethanol gasoline. Due to the implementation of new environmental standards, many vehicles now recommend the use of more environmentally friendly unleaded gasoline and ethanol gasoline. Ethanol gasoline is blended with 90% regular gasoline and 10% fuel ethanol, uniformly labeled as E92, E95, and E98, where 'E' stands for ethanol.
