CRV oil dilution has not been resolved. Below is a detailed introduction to the CRV oil dilution issue: 1. The 2019 CRV model has seen significant improvements, but the 1.5T engine remains the same as before, with no substantial changes. Some owners in northeastern and northwestern regions still report oil dilution and emulsification issues. The oil problem in the 2019 CRV has not been completely resolved. Honda has officially acknowledged that this engine has a fundamental design flaw. Simply replacing parts, using better oil, adjusting the scale limits, or optimizing the control program cannot fundamentally solve the problem. 2. The 2017 CR-V is equipped with a 1.5T direct-injection turbocharged engine. During the engine compression process, some gasoline adhering to the cylinder walls enters the oil pan under pressure. As the engine operates and the oil temperature rises, this gasoline evaporates and re-enters the combustion chamber for re-combustion and emission. However, if the oil temperature is low, the gasoline evaporates slowly, causing some gasoline to remain in the oil, leading to an increase in the oil level.

What does it mean when the yellow light on the fuel gauge illuminates?

The yellow light on the fuel gauge illuminating indicates the following two situations: 1. When starting the vehicle's power supply, a self-check will be performed and then the light will go out, which is normal. The first scenario is when the car's power is turned on, the vehicle conducts a self-check. During this time, not only the engine yellow light but also other fault lights will illuminate simultaneously, then they will all turn off. This is a normal occurrence. 2. If the yellow light remains on after the car is started, it indicates an engine fault. The second scenario is when the car is started, and the engine fault yellow light stays on. This is the ECU alerting that there is a fault in the engine, which is an abnormal condition.

What is the 0-100 km/h acceleration time of the Panamera?

According to official data, the Panamera comes with two engine displacements: 2.9T and 4.0T. The 2.9T model accelerates from 0 to 100 km/h in 5.6 seconds, while the 4.0T model achieves it in 3.2 seconds. Factors affecting a vehicle's 0-100 km/h acceleration time are as follows: Torque: Torque, in simple terms, represents the strength of the force. The greater the torque, the stronger the force pushing the vehicle, resulting in faster acceleration. For example, the Patrol 4.0 has a maximum torque of 394 Nm and a 0-100 km/h acceleration time of 9 seconds, while the Panamera 2.9T boasts a maximum torque of 450 Nm and accelerates from 0 to 100 km/h in 5.6 seconds. Transmission efficiency: The transmission acts as the medium for power delivery, inevitably involving power loss. Higher transmission efficiency leads to better acceleration performance. Generally, transmission efficiency ranks as follows: manual transmission > dry dual-clutch transmission > wet dual-clutch transmission > AT transmission > CVT transmission. The Panamera is equipped with an 8-speed wet dual-clutch transmission. Power-to-weight ratio: The relationship between horsepower and vehicle weight is known as the power-to-weight ratio (measured in Hp/T). A higher power-to-weight ratio results in faster acceleration. The Panamera 2.9T has a power-to-weight ratio of 176.47 Hp/T and a 0-100 km/h acceleration time of 5.6 seconds, while the Patrol 4.0 has a power-to-weight ratio of 109 Hp/T and accelerates from 0 to 100 km/h in 9 seconds.
