The BMW 1 Series should use 95-octane gasoline. Below are the relevant details: Configuration: Features an M Sport multifunction steering wheel with an exclusive chrome "M" emblem. The base model 118i Fashion trim of the 2019 BMW 1 Series sedan has been upgraded with 17-inch wheels, glossy black interior trim, and optional Apple CarPlay. The 118i M Sport package model, in addition to exterior changes, includes mirror components and optional enhanced ConnectedDrive and Apple CarPlay. Powertrain: The new 1 Series sedan offers two powertrain options, including the 118i with a 1.5T inline three-cylinder engine and the 120i with a low-power version of the 2.0T inline four-cylinder engine. The 118i delivers a maximum power of 136 horsepower and a peak torque of 220 N·m, paired with a 6-speed automatic transmission. The 120i produces a maximum power of 192 horsepower and a peak torque of 280 N·m, matched with an 8-speed automatic transmission.
From my experience as a former BMW 1 Series owner, refueling requires special attention. My 1 Series was equipped with a high-efficiency small-displacement turbocharged engine, and the manufacturer recommended using 95-octane unleaded gasoline to ensure smooth engine operation. If lower-grade fuel like 92-octane is used, the engine is prone to knocking—those alarming clicking sounds—and may also experience increased carbon buildup, leading to higher fuel consumption and, in the long run, reduced engine lifespan. BMWs have high fuel quality requirements, so never compromise by using cheaper fuel. I remember once having to refuel with 92-octane when I ran out of gas, and the car had severe jerking sensations—it only improved after a cleaning at the dealership. I recommend checking the instructions on the fuel filler cap before refueling; it clearly states the recommendation for 95-octane gasoline. Additionally, during winter or long-distance driving, fuel temperature fluctuations are more pronounced, and using higher-octane fuel can mitigate risks. Regularly inspecting the fuel filter is also crucial to ensure the fuel system remains clean and free of impurities. Consistently using high-quality fuel enhances power delivery and improves throttle response.
