What kind of fuel does the new LaCrosse 20t use?
2 Answers
The new LaCrosse 20t uses 95 octane fuel. Introduction to 95 octane gasoline: 95 octane gasoline consists of 95% isooctane and 3% n-heptane. When the engine compression ratio is high, high-octane gasoline should be used. If low-octane gasoline is used with a high compression ratio, it can cause abnormal combustion, leading to knocking, increased fuel consumption, and reduced driving power. Benefits of 95 octane gasoline: Higher efficiency: 95 octane gasoline is purer and better, containing more isooctane, which significantly improves the anti-knock performance of vehicles using it. This allows the gasoline to burn more completely, resulting in higher efficiency. Environmental protection: It helps reduce pollutant emissions from vehicles. New vehicles can reduce nitrogen oxide and particulate emissions by 25% and 80%, respectively, while in-use vehicles can reduce overall emissions by 10%~15%. This plays a significant role in protecting the environment and improving air quality.
I've been driving the new LaCrosse 20T for half a year now. This model uses a 1.5L turbocharged engine, and the manufacturer recommends using 95-octane gasoline. Don't try to save money by using 92-octane fuel, as long-term use can easily cause knocking issues and damage the engine's lifespan. Turbocharged models have higher fuel quality requirements, and 95-octane fuel's octane rating is more suitable. You'll notice smoother performance on highways and slightly better fuel economy. I tried 92-octane once and experienced occasional engine shaking, even had to visit a repair shop to check the wiring - quite troublesome. The maintenance manual clearly recommends 95-octane, so I suggest everyone follow this advice. Also, choose reputable gas stations like Sinopec for more reliable fuel quality - don't try to save small amounts at unknown stations. If you're in remote areas where only 92-octane is available, it's okay for emergency use once or twice, but don't make it a habit to avoid higher repair costs later.
