Yes, cars need to warm up before starting. After being parked for a long time, most of the engine oil inside the car flows back to the oil pan. When starting a cold engine, the oil cannot immediately reach the surfaces of all components to form an effective oil film. If you start driving right away, it will increase engine wear. Before the engine reaches its optimal operating temperature, the fuel supply system cannot effectively vaporize gasoline completely due to low temperature (liquid vaporizes when it reaches its boiling point). The ideal operating temperature for an engine is between 80 and 90 degrees Celsius. At this temperature, the gaps between engine components are optimal, the lubricating oil flows better, and the engine operates with higher efficiency, lower fuel consumption, and greater power output.

What kind of engine oil does FAW T-Roc use?

Both the 1.4T and 2.0T models of Volkswagen T-Roc use 5w40 engine oil with a replacement capacity of 4L. Fully synthetic oil is recommended, with a replacement interval of 10,000 kilometers. Recommended brands: internationally recognized brands such as Shell, Castrol, and Mobil; domestic brands include Great Wall, Tongyi, and Kunlun. The tutorial for replacing the oil filter of Volkswagen T-Roc is as follows: 1. Friendly reminder: Before preparing to change the engine oil, turn off the engine for half an hour to allow the oil adhering to the cylinder walls to flow back into the oil pan, otherwise there will be residual oil. 2. First, remove the engine cover. (Remove the four clips of the cover) 3. Use a lift to raise the vehicle for operation, or directly use an electric oil pump to extract the oil. Pull out the oil dipstick and insert the hose of the oil extractor into the dipstick port until it reaches the bottom. 4. Extracting the oil takes about 15 minutes, and the used oil can be collected in a bucket. 5. After extracting the old oil, use a wrench and socket to remove the oil filter, wipe off any excess oil on the contact surface, and then install the prepared new oil filter. (Note: Usually, the oil filter is placed on top, but for some models, the oil filter needs to be removed and installed under the vehicle.) 6. After adding the new oil, it is necessary to check the amount of oil added, which can be observed through the oil dipstick. When checking the oil dipstick for the first time, wipe it clean with a tissue and reinsert it; the second check will be accurate. The oil dipstick has two marks, upper and lower limits, and the oil level should be between these two marks for normal operation.

How to Turn on the Car Wiper?

To turn on the car wiper, simply pull the lever located on the lower right side of the steering wheel. Below is some relevant information about wipers: 1. Wiper Maintenance: Every time you wash your car, in addition to cleaning the windows, it's best to also wipe the wipers with glass cleaner to remove any debris, which can extend their lifespan. 2. Proper Use of Wipers: Wipers are a type of car consumable used to clean rainwater off the windshield. The wiper blades become softer and fit better against the glass only when soaked by rainwater. Therefore, they should only be used when there is rainwater. Avoid dry wiping without water, as this can cause the rubber blades to wear out prematurely.

Classification: Vehicle classification is a fundamental aspect of various vehicle standard systems. Different standards have different vehicle classification methods, which may cross-reference each other while also having their own emphases and differences. Only by correctly understanding and grasping the basic concepts and applicable scopes of different classification methods, and clarifying the connotation and extension of specific definitions, can one accurately apply relevant standard clauses in motor vehicle inspection practices, precisely determine vehicle types, and correctly issue inspection conclusions.
