Can I switch from 98 octane to 95 octane fuel?
2 Answers
It is possible to switch from 98 octane gasoline to 95 octane gasoline. Here are the specific details about cars: 1. 98 octane gasoline: Currently the gasoline with the highest octane rating in China. Although it offers better anti-knock performance and power, vehicles designed for lower octane fuel should not blindly opt for higher octane gasoline. Higher octane numbers are more suitable for engines with larger compression ratios. Engines of cars designed for 95 octane usually have smaller compression ratios, and using 98 octane gasoline might increase engine knocking. 2. Different octane grades of gasoline should not be mixed: For example, mixing 95 and 98 octane gasoline, but long-term use could potentially affect the engine, leading to phenomena such as engine carbon deposits and increased fuel consumption.
I used to always fill up with 98 octane fuel, but later switched to 95 octane to save some money. After driving for over half a year, there haven't been any issues. My car has a turbocharged engine, and I was initially worried it might not adapt well, but the power response remained basically unchanged, with fuel consumption increasing by about 0.3 liters per 100 kilometers. However, 95 octane is 20-30 cents cheaper per liter than 98 octane, so I end up saving several hundred yuan each month. Important reminder: Always check your vehicle's manual before switching! I specifically checked my manual, which stated that 95 octane is within the allowed range, so I felt confident making the switch. If you frequently drive on highways or engage in aggressive driving, it's advisable to stick with 98 octane. For city commuting, 95 octane is completely sufficient. When switching fuel grades, remember to wait until the tank is nearly empty before adding the new grade, and avoid mixing them.
