Can the Cadillac XT4 use 92-octane gasoline?

Cadillac XT4 cannot use 92-octane gasoline and must use 95-octane gasoline. Additional information is as follows: 1. Exterior: The Cadillac XT4 adopts a dual-appearance body design with both stylish and sporty versions. The stylish version features brushed aluminum window trim and chrome door handles, while the sporty version employs a mesh design with carbon black elements on the roof rails, window trim, front grille, underbody panels, and wheels. 2. Four-wheel drive system: The XT4 offers multiple driving mode options including Touring (comfort), Snow/Ice (anti-slip), Sport, and AWD (four-wheel drive). The Disconnect decoupling transfer case can switch to pure two-wheel drive mode in Comfort mode, physically isolating unnecessary fuel consumption and delivering fuel efficiency identical to that of a two-wheel drive vehicle.

As a Cadillac XT4 owner who's been driving this model for nearly three years, I clearly remember the dealership staff emphasizing that it strictly requires 95-octane or higher gasoline when I took delivery. They explained that the turbocharged engine needs high-octane fuel to prevent knocking—that weird engine hiccup sound. The manufacturer's manual explicitly states: 95-octane or above is recommended, with 91-octane being the absolute minimum. While 92-octane gasoline might barely work under normal conditions, one actual test drive immediately revealed noticeably sluggish acceleration, delayed throttle response, and concerns about potential carbon buildup or triggering fault codes with prolonged use. My maintenance technician advised that occasional emergency use of 92-octane won't cause immediate harm, but frequent usage could accelerate engine wear and potentially affect warranty coverage. I believe caring for a car should be like caring for family—don't cut corners on fuel costs. Using 95-octane actually delivers smoother performance and better fuel efficiency in the long run.

I often think about how to save money on car maintenance, especially since fuel costs are quite high. While 92-octane gasoline is cheaper than 95-octane and sounds tempting, it should be used with caution in a Cadillac XT4. The manufacturer clearly recommends 95-octane fuel because the car's design is optimized for higher-octane gasoline performance. If you insist on using 92-octane, the engine may run unevenly, potentially leading to power loss or increased fuel consumption—which could end up being more costly. I personally tried using 92-octane on the highway once, and the throttle response felt sluggish and weak. Afterward, I was worried about potential damage to the engine internals. In the long run, higher repair costs might outweigh the savings, so it's better to stick with the manual's recommendation of 95-octane for both peace of mind and cost-effectiveness. Check the fuel cap—it usually has the recommended octane rating sticker.

From my experience, car engines need to match the gasoline octane rating to operate safely. The Cadillac XT4's engine is refined and requires 95-octane gasoline to prevent knocking. Using 92-octane isn't completely unusable, but it carries significant risks—such as increased noise, reduced efficiency, and potential carbon buildup issues. Always refer to the owner's manual guidance to ensure driving stability.
