To determine if the car battery is dead, follow these methods: 1. Check the battery's charge indicator. When the indicator shows green, it means the battery is fully charged; 2. When the indicator shows black, it means the battery is low and needs to be recharged; 3. When the indicator shows colorless or light yellow, it means the battery is almost completely drained. A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. It is mainly made of lead and its oxides, with a sulfuric acid solution as the electrolyte. The normal service life of a car battery ranges from 1 to 8 years, depending on the condition of the vehicle.

What grade of gasoline does the Volkswagen T-Roc use?

The Volkswagen T-Roc uses 95-octane gasoline. The vehicle's user manual specifies the fuel grade for the engine, and there is also a fuel grade label on the inside of the fuel tank cap. The gasoline grade refers to the octane number, which indicates the anti-knock performance—the higher the octane number, the better the anti-knock performance. The required gasoline grade for a car is determined by the engine's compression ratio; a higher compression ratio requires gasoline with better anti-knock properties. In terms of features, the Volkswagen T-Roc is equipped with a Panorama large-size panoramic sunroof, a Beats Audio sound system, and other amenities.

Can engine oil with a 5-year shelf life still be used in the sixth year?

Unopened engine oil can be stored for 5 years, but if the oil has been opened, it can only be stored for 12 months. It is not recommended to use expired engine oil. The national standard for engine oil shelf life is 5 years, although some oils have a shelf life of up to 12 years. Generally, engine oil within 3 years should be fine. Engine oil is not a food or pharmaceutical product, and according to the General Administration of Quality Supervision, finished products with a shelf life exceeding a certain number of years may not need to indicate an expiration date, which is why engine oil often does not have a shelf life label. Additionally, fully synthetic oil has a longer shelf life than mineral oil. To maintain the performance of lubricating oil, it is generally recommended to store it in a cool, dry place to prevent contamination by water or other impurities.
