What type of fuel should the Baojun RS3 use?
3 Answers
Baojun RS3 uses 92-octane gasoline. How to choose gasoline: The Jetta VS7 can use 92-octane gasoline, but using 95-octane gasoline provides better engine protection. Even high-compression engines can use lower-octane gasoline. Do not blindly choose gasoline based on compression ratio; simply follow the manufacturer's recommendations. Choosing between 95-octane and 92-octane gasoline: 95-octane gasoline consists of 95% isooctane and 3% n-heptane. High-compression engines should use high-octane gasoline. Using low-octane gasoline in a high-compression engine can cause abnormal combustion, leading to knocking, increased fuel consumption, and reduced performance. This type of fuel is suitable for high-end vehicles. 92-octane gasoline has an octane rating of 92 and contains 8% n-heptane, making it suitable for mid-range vehicles.
I've been driving the Baojun RS3 for almost a year now, and it's really cost-effective. The manufacturer recommends using 92-octane gasoline, and with that, the engine runs smoothly with good power response. For daily commuting, the fuel consumption stays around 6.5L/100km, which is quite fuel-efficient. If you accidentally use 95-octane, it might feel slightly smoother, but in the long run, it's unnecessary since 92-octane is cheaper and can save you hundreds of yuan a year. Always remember to refuel at reputable gas stations to avoid potential engine carbon buildup or reduced lifespan from low-quality fuel. Regular maintenance is also crucial—things like checking spark plugs and air filters can keep the engine in top condition. As for engine oil, the manual suggests 5W-30, but that's another topic. In short, following the recommendations is both economical and reassuring.
As an ordinary car owner, I emphasize that using 92-octane gasoline is the most practical choice. The 1.5L engine of the Baojun RS3 is designed to match 92-octane fuel, delivering minimal engine noise and stable acceleration in daily use. Opting for 92-octane can save significant expenses—calculating roughly 0.5 yuan cheaper per liter compared to 95-octane, driving 1,000 km per month could save enough fuel costs in a year to cover a basic maintenance service. However, if you prioritize low prices and refuel at unreliable gas stations, impurities in the fuel may degrade engine performance or even cause malfunctions. I recommend prioritizing Sinopec or PetroChina stations. Additionally, pay attention to the label on the fuel tank cap to avoid mistakenly using higher-octane fuel and wasting money. Regularly replacing the air filter with a better-quality one can also help improve fuel efficiency. In short, sticking with 92-octane is both cost-effective and hassle-free.
