Manual transmission and automatic transmission differ in the following aspects: 1. Manual transmission offers more stable performance and higher transmission efficiency, resulting in better fuel utilization. 2. Automatic transmission provides more convenient operation with flexible gear ratios, making gear shifting easier for the vehicle. Below is relevant information about transmissions: 1. A transmission consists of a gear transmission mechanism and a control mechanism. It is one of the most important components of a vehicle, capable of expanding the driving wheel's torque and speed. 2. With continuous advancements in technology, transmissions have evolved from manual transmissions in the past to continuously variable transmissions (CVT) today. 3. Automatic transmissions consume more fuel than manual transmissions and do not offer the same level of control performance as manual transmissions.

Can the Sagitar use 92 octane gasoline?

The Sagitar can use 92 octane gasoline. Volkswagen officially recommends 92 octane or higher for the Sagitar. The difference between high and low octane gasoline lies in their octane values. High-octane gasoline has a higher octane value, better anti-knock performance, improved engine power, and more complete combustion. Generally, manufacturers suggest a minimum octane rating, and any gasoline that meets or exceeds this recommendation is acceptable. Below are the suitable engine oil specifications for the Volkswagen Sagitar: Mineral oil 5w40 or 10w40, semi-synthetic oil 5w40 or 5w30 certified by VW50200, and fully synthetic oil 0w30, 5w30, 5w40, or 0w40.

Where is the transmission fluid filler port for the Buick Excelle?

Buick Excelle manual transmission fluid filler port is located at the right side of the transmission half-shaft position. 1. Transmission fluid needs to be replaced regularly, as the transmission relies on it for cooling, lubrication, and hydraulic power transmission. Prolonged use leads to significant performance degradation. 2. When transmission fluid quality is substandard, it causes continuous heating of the car's transmission during operation, eventually leading to high temperatures that affect the aging of rubber materials in the car and impair normal driving. The differences between manual transmission fluid and automatic transmission fluid are as follows: 1. Automatic transmission fluid is specifically designed for automatic transmissions, serving both as hydraulic fluid for the torque converter and as lubricant for planetary gear structures and shift mechanisms. 2. Manual transmission fluid is gear oil, with GL-4 suitable for high-speed low-torque and low-speed high-torque conditions, lubricating car hypoid gear drive shafts and manual transmissions.

Where is the air conditioning filter located in the new Volkswagen Jetta?

The air conditioning filter in the new Jetta is located on the passenger side, beneath the glove compartment, near the center console. Lift the floor panel to see it—there are three clips in total. Gently pry them open to access the air filter inside. Here are some recommendations for using the car's air conditioning: 1. When warming up the car in the morning, avoid turning on the heating immediately. Wait until the engine coolant temperature rises before activating the air conditioning. Avoid setting the temperature too high, as prolonged driving at high temperatures can cause drowsiness. 2. If the airflow from the vents is weak, check if the air filter is dirty. After using the recirculation mode for an extended period, switch to fresh air mode or open the windows for ventilation. 3. After using the air conditioning for cooling, do not turn it off immediately. Instead, set the blower to maximum to dry out moisture in the air conditioning ducts, which also helps prevent bacterial growth on the filter.
