Can Cadillac Use 92 Octane Gasoline?
2 Answers
Cadillac cannot use 92 octane gasoline. Most models under the Cadillac brand are equipped with turbocharged engines, which require a minimum of 95 octane gasoline. Using 92 octane gasoline may cause engine knocking. 95 octane gasoline consists of 95% isooctane and 3% n-heptane. Taking the Cadillac XTS as an example, its body dimensions are 5131mm in length, 1852mm in width, and 1501mm in height, with a wheelbase of 2837mm. In terms of power, the Cadillac XTS is equipped with a 2.0-liter turbocharged engine, delivering a maximum power of 198kW and a maximum torque of 269Nm.
As an ordinary car owner who has driven a Cadillac, using 92-octane gasoline is generally not recommended because most Cadillac engines are high-performance designs that require higher-octane fuel to prevent knocking issues. The lower the octane rating, the more likely it is to cause abnormal noises and vibrations during combustion, affecting driving comfort and power output. From my experience, fuel consumption tends to increase when using 92-octane gasoline, and prolonged use may damage engine components such as pistons or valves, leading to higher repair costs. While it may save money in the short term, protecting the vehicle is more important. I suggest checking the owner’s manual to confirm the specific fuel grade requirements for your model; most Cadillacs recommend 95-octane or higher gasoline. For cost savings, you can look for gas station discounts or use apps to find deals, but never compromise your vehicle’s health. During routine maintenance, mechanics always emphasize the importance of fuel selection.
