What grade of gasoline can be used for the Changan CS35?
3 Answers
The Changan CS35 can use 92-octane gasoline. Gasoline is a volatile, flammable hydrocarbon mixture liquid obtained from petroleum through distillation, cracking, or pyrolysis, and can be used as fuel. The body dimensions of the Changan CS35 are: length 4170mm, width 1810mm, height 1670mm, with a wheelbase of 2560mm, a minimum ground clearance of 180nm, and a fuel tank capacity of 52 liters. The Changan CS35 is equipped with a 1.6L naturally aspirated engine, delivering a maximum power of 92kW and a maximum torque of 160Nm, paired with a 5-speed manual transmission. It features a front suspension type of MacPherson independent suspension and a rear suspension type of torsion beam rear suspension.
I drive a Changan CS35 SUV, and it runs best on 92-octane gasoline. The manual clearly recommends using 92-octane or higher unleaded gasoline. After two years of use, the engine runs smoothly, and the fuel consumption is very economical. Using higher-octane fuel like 95-octane is purely a waste of money because the engine's compression ratio isn't high enough, and using 95-octane may lead to incomplete combustion, accumulating carbon deposits over time. I refuel with 92-octane every week for my commute, choosing large gas stations like Sinopec for cleaner fuel quality. Developing good habits, such as regularly checking the fuel system and tire pressure, can also improve fuel efficiency, allowing a full tank to go further. Overall, the cost per kilometer is very low.
As a frequent driver, the Changan CS35 is best suited for 92-octane gasoline. The engine is designed based on 92-octane fuel, and using higher-octane gasoline offers no additional benefits—it may even affect the ignition system. I've personally tested this and found that using 95-octane fuel slightly increases fuel consumption without improving performance. The key is to use high-quality fuel sources and avoid small, unreliable gas stations to prevent impurities from clogging the fuel injectors. Regular maintenance, such as changing the air filter and engine oil, can help the engine last longer. In summer, 92-octane fuel is sufficient even with the AC on. Before long trips, fill up the tank and adjust the tire pressure correctly to save costs and drive with peace of mind.
