Should the Corolla 1.2T use 92 or 95 octane gasoline?
2 Answers
The Corolla 1.2T should use 92 octane gasoline. Here are some precautions for refueling: Avoid overfilling the tank: If the gasoline tank is overfilled, the high summer temperatures combined with the heat generated by the car itself can cause the gasoline to expand and contract. To prevent the fuel tank from being damaged by the expanding gasoline volume, there is a vent hole at the top. If the tank is overfilled, gasoline may overflow through the vent hole, which could lead to spontaneous combustion if exposed to an open flame, with potentially disastrous consequences. Additionally, gasoline overflowing through the vent hole may drip onto the car body, causing some corrosion. Try to avoid waiting until the fuel light comes on to refuel: While driving, always pay attention to the fuel gauge. When the pointer indicates that only a quarter of the fuel remains, it's time to refuel. It's best not to wait until the fuel light comes on before refueling. Modern cars use electric fuel pumps that rely on gasoline for lubrication and cooling. Frequently waiting until the fuel light comes on to refuel can prevent the fuel pump from receiving adequate lubrication and cooling, ultimately reducing its lifespan.
I've been driving a Corolla 1.2T for several years, always using 92-octane gasoline which works perfectly fine—the engine runs smoothly with low fuel consumption. The manual states that 92 or higher is suitable. While 95-octane costs a few cents more per liter, it offers no significant benefits, with only negligible power gains. During periods of high fuel prices, sticking to 92-octane can save a substantial amount—enough for a nice meal each month. In cases of poor fuel quality, 95-octane might provide slightly better knock resistance, but at reputable gas stations, 92-octane is reliable. Don’t fall for unnecessary upsells; the key is matching the engine to lower-octane fuel. For maintenance, remember to change the oil filter regularly to keep things hassle-free.
