Can You Add 92 Gasoline After Adding 95? Gasoline can be classified into different types based on its source: straight-run gasoline, catalytic cracked gasoline, thermal cracked gasoline, reformed gasoline, coker gasoline, alkylate gasoline, isomerate gasoline, aromatized gasoline, etherified gasoline, and polymerized gasoline. The working principle of the gasoline supply system is as follows: the fuel pump draws diesel from the fuel tank, filters out impurities through the filter, and then enters the low-pressure oil chamber of the injection pump. After increasing the fuel pressure, it is transported to the injector through the high-pressure fuel pipe. The injector sprays the fuel into the combustion chamber in a mist form, forming a mixture that combusts and performs work. The exhaust gas is then discharged into the atmosphere through the exhaust system.
I've always believed that driving should be as meticulous as caring for an old friend. I remember my old car—back then, I often mixed fuel grades, switching between 92 and 95 without major issues. But times have changed, and modern engines are far more precise. Mixing different octane ratings in the tank averages out the octane level, which for your car is like eating unfamiliar food—it can cause knocking (abnormal combustion) and damage engine components. My advice is to check your manual or consult a professional technician. If your car requires 95-octane fuel, don’t casually mix in 92. In an emergency, like a long trip where only 92 is available, one fill-up might be manageable, but don’t make it a habit. Prolonged mixing can weaken performance, increase fuel consumption, and the small savings won’t cover repair costs. Drive safely—don’t add unnecessary strain to your engine.
