What grade of gasoline should a Lexus ES use?

Lexus ES should use 92-octane gasoline, as this grade is recommended in the vehicle's official user manual. In addition to checking the appropriate gasoline grade in the user manual, you can also find it on the fuel tank cap, which will be clearly marked. Generally, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92-octane gasoline, those between 10.0-11.5 should use 95-octane gasoline, and if the compression ratio is higher, 98-octane gasoline is recommended. However, with the application of new technologies, the compression ratio alone cannot determine the gasoline grade, as high compression ratios can also be adjusted to use lower-octane gasoline. Other factors, such as ignition timing, turbocharging technology, and Atkinson cycle technology, also play a role. Generally, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. If you occasionally use the wrong gasoline grade in a Lexus ES, simply switch back to the correct grade after the current tank is used up. However, prolonged use of the wrong gasoline grade can have the following effects: Using a higher-octane gasoline in a vehicle designed for a lower grade will not cause damage, but the increased octane number can alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. Using a lower-octane gasoline in a vehicle designed for a higher grade can cause engine knocking. The significantly lower octane number reduces the fuel's ignition point, causing premature ignition during the compression stroke. If the fuel ignites before the spark plug fires, resistance occurs during the upward stroke. This resistance makes the engine run very unstably. Mild knocking may only increase noise without significant engine damage, but severe knocking indicates serious engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, potentially leading to cylinder scoring.

How Long Does the Buick Envision's Battery Last?

The battery life of the Envision is approximately three years. Generally, the lifespan depends on usage conditions, and with proper maintenance, it can last up to six years. Below is additional information about the battery: 1. If you notice poor power supply, avoid using vehicle power sources such as electric air pumps, audio systems, warning lights, or power windows. Excessive power consumption will only worsen the battery's insufficient supply, make starting difficult, and shorten its lifespan. Frequent discharging and recharging can lead to battery memory effect. 2. During daily use, avoid situations with large current fluctuations. This can accelerate battery aging, as battery performance changes require a gradual process. 3. The battery requires regular maintenance. Timely detection of abnormal battery performance degradation allows for immediate troubleshooting. Proper maintenance can slow down the aging of automotive components and extend the battery's service life.
