ES uses 92-octane gasoline. Below is additional information about the Lexus ES: 1. The Lexus ES is one of the highest-selling models in Lexus history and the only series in the Lexus lineup that adopts a front-wheel-drive system. It features a lighter steering wheel, less distinct road feedback, and softer suspension, but offers superior ride comfort. 2. The Lexus ES is equipped with rich configurations, exquisite craftsmanship, and comfortable seats. 3. The new-generation ES achieves outstanding comfort and safety performance while also utilizing leading technology to reduce energy consumption and emissions, perfectly balancing luxury quality with environmental friendliness. 4. The new-generation ES adopts a lightweight body design, using high-strength steel to reduce the weight of the body frame structure, achieving lower vehicle weight and energy consumption.

When driving my ES, I always fill it with 92-octane gasoline or higher. The manufacturer recommends a minimum of 91 octane, depending on the latest model year when you purchased the car. My ES is an older model, but I prefer using premium unleaded gasoline to avoid engine knocking and ensure smooth driving. In fact, there’s a label on the fuel cap or detailed instructions in the owner’s manual—those are the most reliable sources. Using lower-octane fuel for a long time may increase carbon deposits in the engine and reduce power, especially during high-load driving. Of course, modern cars have sensor protection systems, so an occasional mistake isn’t a big deal, but making it a habit could lead to higher repair costs. Every time I refuel, I check the gas station’s quality to avoid mixing in substandard fuel. In short, safety comes first—using the right fuel extends your car’s lifespan and keeps it running smoothly.

I've been driving a ES for several years and usually opt for 91 octane or higher gasoline for simplicity and convenience. Every time I visit the gas station, I prioritize 93 octane unleaded fuel because it makes the engine run quieter and more efficiently. If money is tight, 92 octane is acceptable, but don't make it a habit—the car will protest. I recommend checking the little manual inside your car or the label on the fuel filler cap; Lexus specifies a minimum of 91 octane. From my experience, while premium fuel is more expensive, the actual fuel consumption doesn't differ much, and in the long run, it saves on maintenance costs. Additionally, avoid frequently switching between different gas station brands, as inconsistent fuel quality may cause engine vibrations. Once you develop this habit, your car will run more smoothly and reliably.

As someone who knows a thing or two about cars, I recommend using at least 91 octane gasoline for the ES from the get-go—don't go below this standard. The engine is designed to require high-octane fuel to prevent knocking. Using lower-quality fuel long-term can lead to ignition delays and power loss. Checking the fuel cap or manual yourself is far better than listening to random guesses. In an emergency, using 89 octane temporarily won't cause major harm, but don't make it a habit. Regularly inspect the fuel system to keep the engine in good health.

From a cost-saving perspective, I've tried several fuel grades when driving my ES – 91 octane is the minimum requirement, but you don't always need to go for the premium option. While 93 octane can slightly improve performance, it has negligible impact on daily fuel consumption. Real fuel economy comes from driving habits. During periods of high fuel prices, I use 92 octane but always ensure it's from reputable gas stations. Regular maintenance of air filters and spark plugs can reduce fuel quality dependency. If wrong fuel is accidentally used, the car may develop abnormal noises – address it promptly to avoid major repairs.

My ES requires gasoline with an octane rating of 91 or higher to ensure powerful and safe engine performance. Using lower-octane fuel may cause knocking issues, especially during high-speed driving or uphill climbs. I've developed the habit of checking the manual and verifying the fuel grade at every refueling. High-performance engines rely on high-quality fuel to maintain longevity, so during maintenance, it's essential to check oil pressure and clean carbon deposits.
