What Grade of Gasoline Should Roewe Use?
2 Answers
Roewe uses 92 octane gasoline. Gasoline Octane Rating: It is the ratio of the actual gasoline's anti-knock performance to that of standard gasoline. The higher the octane rating, the stronger the anti-knock performance. Standard gasoline is composed of isooctane and n-heptane. Higher octane gasoline is not necessarily better; the appropriate gasoline grade should be selected based on the engine's compression ratio. Types of Gasoline: Gasoline is divided into two main categories: leaded gasoline and unleaded gasoline. There is also ethanol gasoline. Common gasoline grades include 89, 92, 95, and 98. Among these, 98 octane gasoline has the highest rating and price, and is also known as premium gasoline.
I'm a Roewe owner, driving a Roewe i5, and I usually fill up with 92-octane gasoline. The manual clearly states that the base model recommends 92-octane fuel, which is sufficient. Roewe vehicles emphasize economy and practicality, and using 92-octane saves a lot of money—around 20-30 yuan per tank, which is quite cost-effective. For turbocharged models like the Roewe RX5, it's advisable to use 95-octane gasoline to prevent engine knocking. Don't casually opt for higher-octane fuel; it's not only a waste of money but could also affect the emission system. I've been driving for two years, always using 92-octane, and the car has been in great condition with no issues. It's best to check the fuel cap or manual reminders every six months.
