What Type of Gasoline Should the Buick Enclave Use?
3 Answers
The manufacturer of the Buick Enclave recommends using 95-octane gasoline. Depending on the model version, the fuel tank capacity of the Buick Enclave is either 73 liters or 82 liters. To refuel, simply press one side of the fuel tank cap to open it; there is no need to unlock the car after turning off the engine. The Buick Enclave has dimensions of 4981mm in length, 1953mm in width, and 1727mm in height, with a wheelbase of 2863mm. It is a 5-door, 7-seat SUV equipped with a 9-speed automatic transmission and a 2.0T L4 engine, delivering a maximum horsepower of 237ps and a maximum torque of 350nm, with a top speed of 210km per hour.
Last time before taking my friend's Enclave on a long trip, I specifically researched the fuel requirements. The fuel cap clearly states 92 octane or higher unleaded gasoline, and I double-checked the owner's manual to confirm. For daily city commuting, 92 octane is perfectly sufficient, but I feel the engine runs smoother with 95 octane on highways. However, the dealership technician said there's no need to deliberately use higher octane fuel since its 2.0T engine is originally calibrated for 92 octane. I remember once when the gas station ran out of 92 octane, I temporarily filled up with 95 octane and didn't notice any significant difference. The key point is not to use anything below 92 octane just to save money - it could damage the engine and might trigger the check engine light.
I've been using 92-octane gasoline for my Enclave since I bought it over two years ago. Both the owner's manual and fuel filler cap clearly state that 92-octane is acceptable. Once at a gas station, I met a fellow Enclave owner who insisted that 95-octane is better for turbocharged engines. I simply showed him the manufacturer's recommendation in the manual. The main difference between 92 and 95 is the anti-knock properties, but this engine's knock control system is very intelligent - using 92-octane causes absolutely no issues. Actually, fuel quality matters more than the octane rating. I always fill up at Sinopec stations and have never experienced engine knocking or check engine lights.
