What grade of gasoline should a Lexus ES300h use?
1 Answers
It is recommended to use 95 or higher octane fuel. The engine compression ratio of the ES300h is 14:1, and 95 octane gasoline is suggested for compression ratios above 10. The reasons for high fuel consumption are as follows: Tire factors: Tires are relatively easy to check, so they should be inspected first. If the tire pressure is insufficient, fuel consumption will increase. If the tire pressure is normal, then check the wear level of the tires. Severe tire wear can lead to frequent slipping, which also increases fuel consumption. Excessive engine carbon buildup: If there is a significant amount of carbon buildup in the engine over a short period, it can also cause high fuel consumption. This situation is likely due to the use of substandard fuel. The solution is to add a certain amount of cleaner when refueling. If the effect is not noticeable, it indicates a large amount of carbon buildup in the engine, in which case it is best to take the car to a 4S shop or repair shop for the technician to clean the carbon deposits inside the engine. Oxygen sensor damage: As an internal control unit of the car, the oxygen sensor primarily monitors the air-fuel ratio of the engine. Once it is damaged, it will cause an imbalance in the engine's air-fuel ratio, inevitably leading to abnormally high fuel consumption. When the vehicle is running, the exhaust pipe will emit darker-colored exhaust gases. In this case, the oxygen sensor should be replaced as soon as possible.
