Automobile maximum gross mass refers to the weight of a fully equipped vehicle with passengers (including the driver) and cargo loaded as per regulations. Below is relevant information: 1. Determination of vehicle gross mass: For passenger cars, vehicle gross mass = curb weight + driver and passenger weight + luggage weight For buses, vehicle gross mass = curb weight + driver and passenger weight + luggage weight + accessory weight For trucks, vehicle gross mass = curb weight + driver and assistant weight + luggage weight The curb weight of a vehicle, previously commonly referred to as "unladen weight". 2.

Is it acceptable for the four tires of a new car to have different production dates?

It is acceptable for the four tires of a new car to have different production dates. A difference of one week is not a problem, but a longer time difference is not acceptable. Car tires have a warranty period, which varies by brand but is generally around 3 years. If any quality issues arise within the warranty period, you can go to the tire brand store to request replacement, repair, or refund services under the three-guarantee policy. Signs that tires need to be replaced include: 1. Tire wear reaching the limit—there are usually small raised indicators in the tire tread grooves to measure wear limits; when the tire wears down to the level of these indicators, it indicates that the tire needs to be replaced. 2. Severe tire aging—when the tire rubber shows significant aging and cracking, the tires should be replaced promptly.

Is Engine Bay Cleaner Effective?

Engine bay cleaner is effective under two conditions: 1. If the engine does not leak oil and only has surface dust and dirt, cleaning is not necessary and poses no harm to the engine; 2. If the engine leaks oil, regular cleaning is required. A common cause of engine oil leaks is a leaking valve cover gasket, which can spread oil over the entire engine. Oil tends to attract dust, and when mixed with dirt and exposed to the engine's high temperatures, it forms a thick layer of sludge. This sludge is corrosive and can accelerate the aging of wiring and rubber components.

How Often Should Brake Fluid Be Replaced?

Brake fluid should be replaced every 2 years. Brake fluid has certain corrosive properties and strong water absorption. Nowadays, maintenance stations have specialized tools to detect the water content in brake fluid, allowing for a test to determine if replacement is necessary. It is essential to regularly replace brake fluid when it reaches the maintenance interval, and it is recommended to follow the maintenance cycle specified by the manufacturer. Over time, the rubber cups and pistons in the brake pump may wear out, causing the brake fluid to become contaminated. When selecting brake fluid, be cautious as substandard or low-quality brake fluid can corrode the rubber seals in the brake pump and affect braking performance. If the brake fluid is low, it is advisable to purchase the original brake fluid from a specialized repair shop.
