What grade of gasoline should the Changan Unit use?
2 Answers
The Changan Unit uses 92-grade gasoline. The Changan Unit is a compact SUV under the Changan brand. Taking the Changan Unit 2020 Flagship model as an example, its body dimensions are: length 4515 mm, width 1870 mm, height 1565 mm, with a wheelbase of 2710 mm. The Changan Unit 2020 Flagship model is equipped with a 1.5L turbocharged engine, with a maximum power of 132 kW, a maximum power speed of 5500 rpm, a maximum torque of 300 Nm, and a maximum torque speed range of 1250 to 3500 rpm. It adopts MacPherson independent suspension and multi-link independent suspension.
I drive a Changan UNI-T, and the official recommendation for this 1.5T turbocharged engine is to use 92-octane gasoline, which is also indicated inside the fuel tank cap. For daily city commuting, I always use 92-octane—it's perfectly adequate and saves money. The difference is especially noticeable when gas prices spike; a full tank can save enough for a cup of milk tea. However, when driving on highways or climbing slopes with a full load, I occasionally switch to 95-octane, as the throttle response feels crisper. Just remember: don’t cheap out with anything below 90-octane—long-term use of low-grade fuel can cause engine knocking and damage. Also, ignore gas station upsells for 98-octane; it’s a total waste. Regularly cleaning carbon deposits from the fuel system does help with fuel efficiency.
