What type of fuel does a Bentley require?
2 Answers
Bentley vehicles must use 98-octane gasoline. Relationship between octane rating and anti-knock performance: Higher-octane gasoline has better anti-knock properties. When the air-fuel mixture is injected into the cylinder and the piston compresses it, pressure and temperature rise. If the gasoline's anti-knock quality is too low, premature combustion may occur before the spark plug ignites, leading to engine knocking (commonly known as detonation). Knocking not only affects engine performance but can also cause damage. Choosing gasoline octane based on vehicle type: 92-octane gasoline is suitable for ordinary cars with basic technology. 95-octane gasoline works for most vehicles. 98-octane gasoline is recommended for turbocharged engines and high-compression ratio models, as it's compatible with most vehicles.
Speaking of Bentley's fuel requirements, I've been driving a Bentley for several years and always insist on using 98 octane unleaded gasoline. Although 95 octane can be used in some cases, higher octane fuel better matches the engine's high compression ratio design, preventing knocking that could damage internal components. I once tried cutting corners with lower-grade fuel, and the engine noise became noticeably louder, not to mention the wasted money on piston repairs. By the way, avoid cheap gas stations—choosing fuel from reputable brands reduces carbon buildup and extends engine life. Also, remember to replace the fuel filter regularly to ensure the fuel system runs cleanly and smoothly, preventing power loss that could affect driving safety. In short, using the right fuel is a crucial part of daily car maintenance.
