Why do 4S shops add engine oil to the highest point?

4S shops add engine oil to the highest point because the car is in a hot state when owners go to 4S shops for maintenance. There are two points to note when adding engine oil: 1. When selecting engine oil: it is necessary to strictly follow the engine oil grade specified in the car manual. If there is no engine oil of the same grade, you can use a higher grade, but you cannot use a lower grade instead; 2. When adding engine oil: the amount of engine oil added should be slightly lower than the standard scale. Too much engine oil will increase the rotation resistance of the crankshaft, reduce the output power of the engine, and excessive engine oil will enter the combustion chamber to participate in combustion, causing the vehicle to burn engine oil, emit blue smoke, and even increase fuel consumption.

Motorcycle Inspection Exemption Policy?

Motorcycles exempt from inspection for 6 years do not require on-site testing within the first 6 years. Owners only need to collect the inspection compliance mark at the traffic police station or vehicle management office in the 2nd, 4th, and 5th years. After exceeding 6 years, on-site testing becomes mandatory. Below are relevant introductions about motorcycles: 1. Composition: Motorcycles consist of five main components - engine, transmission system, running gear, steering and braking systems, and electrical instrumentation equipment. 2. Starting Method: Motorcycles primarily use kick-start mechanisms. The starting mechanism includes sector gear starting mechanisms represented by models like the Xingfu XF250 motorcycle. The kick-start gearshift lever drives the sector gear, starting ratchet, clutch assembly sprocket, front chain, and crankshaft sprocket to rotate the crankshaft and start the engine.

Can the Porsche 718 accommodate four people?

Porsche 718 Boxster and 718 Cayman are both two-door, two-seater sports cars and cannot seat four people. Although the Porsche 718 sacrifices some passenger space, its advantages as a sports car are quite evident. The mid-engine layout places the center of gravity at the center of the body, resulting in a small horizontal inertial moment during high-speed cornering, which gives the car perfect handling. Due to its small inertial moment, it offers excellent maneuverability with very sharp steering. Below is an introduction to the Porsche 718: 1. The Porsche 718 is Porsche's entry-level sports car, available in two models: the sports car Porsche Cayman and the convertible Porsche Boxster. 2. Porsche officially states that the car's total weight will be controlled at 1,200 kilograms, which is 100 kilograms lighter than the previous Boxster. The power output has also been reduced, possibly featuring a four-cylinder engine with a displacement of 2.0 liters and an output of 286 horsepower, or Porsche's 2.5-liter engine with an output of 360 horsepower.

What are the precautions for part-time four-wheel drive?

Regarding the precautions for part-time four-wheel drive, the following points should be noted: 1. Situations where four-wheel drive mode should not be used: Do not use four-wheel drive mode when driving on paved roads or surfaces with good traction and high friction. (Using four-wheel drive mode on paved roads can make steering difficult, posing driving hazards and potentially damaging the four-wheel drive system.) 2. Situations where four-wheel drive mode should be used: Activate four-wheel drive mode when driving on slippery surfaces such as rainy or snowy roads, muddy mountain paths, or sandy unpaved roads with low friction. This can significantly improve driving safety. 3. Characteristics of part-time four-wheel drive: Part-time four-wheel drive is purely mechanical, offering strong operability, reliability, and durability. The driver must assess road conditions and manually switch driving modes. Part-time four-wheel drive is the most common drive mode in SUV models, ensuring both vehicle power and off-road capability while maintaining fuel efficiency.
