Compton engine oil has a shelf life of only two years. Once the seal is opened, long-term stored oil will gradually acidify and deteriorate, making it unsuitable for lubrication and heat dissipation. The shelf life of engine oil is introduced as follows: Unopened engine oil: The shelf life is generally about 3-5 years, and there are also oils with a shelf life of over 10 years, though they are probably not needed; Engine oil poured into the engine: The effective periods for mineral oil, semi-synthetic oil, and full synthetic oil vary by brand and grade. Please follow the manufacturer's recommendations. Generally, mineral oil lasts for 5000 kilometers or six months; semi-synthetic oil for 7500 kilometers or eight months; full synthetic oil for 10000 kilometers or one year; Remaining engine oil after maintenance: If stored properly, the remaining oil after maintenance can be kept for about one year. However, for safety, it is recommended to use it within about six months.

Does the Mercedes-Benz C180L have ambient lighting?

Mercedes-Benz C180L does not come with ambient lighting as standard, but it can be optionally installed. Here is some relevant information about ambient lighting: 1. Interior ambient lighting is a decorative lighting system, usually in colors such as red, blue, or green, primarily designed to enhance the cabin's appearance at night, create an atmosphere, and set the mood inside the vehicle. It is important to note that the lighting color should not interfere with normal safe driving. 2. Dot-style ambient lighting is also a type of ambient lighting, but its cost and effect are lower than those of strip-style ambient lighting. Although the effect is not very impressive, it can still significantly contribute to improving the in-car atmosphere.

How to Turn Off the Auto Start-Stop Function in Bora Legend?

The auto start-stop button in Bora Legend is located to the right of the gear lever, marked with an 'A'. By default, it is in the 'on' state. To turn it off, simply press the button once. Here is a detailed introduction to the engine auto start-stop system: 1. The engine auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light) and restarts it when it's time to move again. This system is achieved by equipping the traditional engine with an enhanced motor that has idle start-stop functionality, allowing the engine to completely shut off when idle stop conditions are met. When the vehicle needs to move again, the idle start-stop motor system quickly responds to the driver's start command, rapidly restarting the engine for seamless transition, significantly reducing fuel consumption and exhaust emissions. 2. The working principle is that when the vehicle stops due to traffic congestion or at an intersection, the driver presses the brake pedal and shifts to neutral. At this point, the Start/Stop system automatically checks: the engine is idling and not in gear; the wheel speed sensors of the anti-lock system show zero; the electronic battery sensor indicates sufficient energy for the next start. 3. Once these three conditions are met, the engine automatically stops. When the traffic light turns green, the driver presses the clutch (in manual transmission models), and the 'start-stop' function can be activated immediately, quickly restarting the engine. In automatic transmission models, simply releasing the brake or turning the steering wheel will automatically restart the engine, allowing the driver to accelerate immediately, all while remaining in D (Drive) mode.
