Is unleaded gasoline 92 or 95?

[DiJade]

Both 92 and 95 gasoline at regular gas stations are unleaded gasoline. The following is an introduction to unleaded gasoline: 1. Introduction: Unleaded gasoline contains only trace amounts of lead from crude oil, generally 0.01 grams per liter of gasoline. Its octane rating is 95, slightly lower than the octane rating (97) of other grades of leaded gasoline currently available. The use of unleaded gasoline can effectively control harmful substances in automobile exhaust, reducing pollution such as hydrocarbons (HC causing smog), carbon monoxide (CO toxic), and nitrogen oxides (NOx forming acid rain). 2. Notes: Unleaded gasoline is not harmless gasoline. In order to reduce the degree of air pollution and improve people's health, unleaded gasoline has been promoted nationwide since 2000, achieving the lead-free gasoline, fundamentally solving the problem of lead pollution in automobile exhaust. However, many people mistakenly regard unleaded gasoline as harmless green gasoline and relax their guard against automobile exhaust in daily life. In fact, unleaded gasoline still has many pollution problems.
