What grade of gasoline does the Lexus ES use?
3 Answers
Lexus ES uses 95-octane gasoline. 95-octane gasoline has higher anti-knock performance than 92-octane but lower than 97-octane. Taking the 2020 Lexus ES as an example, it belongs to the mid-to-large-sized car category with body dimensions of 4975mm in length, 1866mm in width, and 1447mm in height, a wheelbase of 2870mm, a fuel tank capacity of 49.3 liters, and a curb weight of 1720kg. The 2020 Lexus ES features a MacPherson strut front suspension and a multi-link rear suspension. It is equipped with a 2.5L naturally aspirated engine producing a maximum horsepower of 178PS, a maximum power of 131kW, and a maximum torque of 221Nm, paired with an electronic continuously variable transmission.
I remember when I drove a Lexus ES, the manual clearly stated that 92-octane or higher gasoline should be used. If you use lower-octane fuel, such as below 90-octane, the engine is prone to knocking, which can damage the car and cost more in the long run. I usually fill up with 92-octane—it's economical and practical, and the fuel consumption remains stable. Occasionally using 95-octane is fine too, as it helps reduce carbon buildup, but there’s no need to regularly opt for the more expensive fuel. When refueling, pay attention to the quality of the gas station and avoid obscure or unreliable ones. Additionally, there might be slight differences between different model years. Mine is a 2019 model, and the owner group all agree that 92-octane is sufficient. Developing the habit of checking the manual can save a lot of hassle—safety first, after all.
As someone who frequently interacts with this car, the Lexus ES is recommended to use 92 or 95 octane fuel. Don't be tempted to use lower-grade fuel to save money. The engine is designed to operate optimally within this range, and using fuel below 90 octane may trigger the malfunction indicator light. I've seen cases where new drivers used the wrong fuel, leading to increased engine carbon buildup. It's advisable to regularly inspect the fuel system and filtration system. From an economic perspective, using 92 octane offers good value for money, and the minimum requirement is usually indicated on the fuel tank cap. If you want to enhance driving smoothness, using 95 octane can help, but you'll need to weigh the additional cost. Overall, following the manufacturer's guidance is the safest approach.
