Does using 92-octane gasoline affect turbocharged engines?
2 Answers
Using 92-octane gasoline in turbocharged engines does have effects, specifically as follows: 1. Poor fuel efficiency: The lower combustion efficiency of the gasoline can lead to increased carbon deposits in the car, reducing the engine's performance. 2. Engine knocking: Due to high-temperature vaporization combustion, the gasoline is more prone to knocking inside the engine cylinders. Information about turbocharging is as follows: 1. Classification: TURBO is divided into four types: mechanical supercharging, pressure wave supercharging, exhaust gas turbocharging, and compound supercharging. 2. Turbocharging: Essentially an air compressor, it increases the engine's intake air volume by compressing air, thereby enhancing the engine's power and torque, making the car more powerful.
I've been driving a turbocharged car for three years. Once at a remote gas station, only 92-octane fuel was available, so I tried filling up with it. As a result, the engine developed slight knocking sounds, had noticeably less power during acceleration, and fuel consumption was higher than usual. Later at the 4S shop, the mechanic explained that turbocharged engines have high compression ratios, and 92-octane fuel's low anti-knock index makes it prone to detonation. Long-term use could damage pistons and cylinders. Since then, I've never taken the risk again and always use 95-octane fuel. Though more expensive, the engine runs smoothly without issues. I suggest you check your vehicle's manual - it definitely specifies the recommended fuel grade. Don't risk major damage to save small money. While turbocharging technology enhances driving pleasure, it demands strict fuel quality requirements - this is crucial to remember.
