What type of fuel does a Bentley require?

[DelCooper]

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.
