Should the Verano turbocharged engine use 92 or 95 octane gasoline?
1 Answers
The Verano turbocharged engine should use 95 octane gasoline for better anti-knock performance. 95 octane gasoline consists of 95% isooctane and 3% n-heptane. When the engine has a high compression ratio, high-octane gasoline should be used. Using low-octane gasoline in a high-compression ratio engine can cause abnormal combustion, leading to knocking, increased fuel consumption, and reduced driving power. The Verano is a compact car under SAIC-GM Buick. It measures 4723mm in length, 1802mm in width, and 1466mm in height, with a wheelbase of 2700mm. The body type is a 4-door, 5-seater sedan, and it comes with a 6-speed automatic transmission.
