Volkswagen Santana performs well with Castrol or Mobil brand engine oils. The Santana series is equipped with naturally aspirated engines, which can use 30-viscosity semi-synthetic or full synthetic engine oil. During the break-in period of a new Santana, 5W40 oil is recommended. For later maintenance, you may opt for semi-synthetic oils from brands like Shell or Total. Semi-synthetic oil is mainly suitable for the EA211 1.5L naturally aspirated engine in the Santana, while the 1.4T engine requires full synthetic oil. The engine oil should meet ACEA, A3B4, or C3 certifications. The A3B4 standard indicates a high-temperature shear value of at least 3.5, ensuring the oil film's strength at high temperatures and preventing oil burning. For new cars, 0-30 oil is recommended as an all-season oil. The viscosity of engine oil changes with temperature, so it's important to pay attention to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity, with 5W representing the ability to withstand temperatures as low as -30°C. A smaller number means better low-temperature fluidity, resulting in smoother cold starts for the car. The second number represents the oil's kinematic viscosity at 100°C, with higher values indicating better viscosity retention at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in a Volkswagen Santana is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan underneath to catch the old oil until it stops flowing. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain out; Use a specialized wrench to remove the oil filter; Apply oil to the seal of the new oil filter and tighten it clockwise by hand; Add the new engine oil through the filler cap on the engine valve cover, typically filling about three-quarters of the oil container; Start the engine and let it run for 5 minutes, checking for any leaks around the oil drain plug and oil filter. If leaks are found, repairs should be made; After stopping the engine, pull out the dipstick to check that the oil level is within the standard range.

What Causes Engine Shaking in a New Car?

Reasons for engine shaking in a new car: 1. Deterioration or loosening of engine mounts: Engine mounts are designed to reduce vibration and absorb shocks during engine operation, while also securing the engine in place. If the mounts become worn or loose, engine shaking becomes noticeably severe; 2. Engine misfire: The exhaust flow from the vehicle shows obvious intermittency, accompanied by severe shaking of the exhaust pipe, making the engine vibration clearly noticeable, sometimes with a sputtering sound; 3. Cold start: During a cold start, the engine's lubrication is less effective, and the engine oil has poor fluidity and is more viscous, leading to abnormal noises from mechanical friction. Additionally, low coolant temperature, overly rich air-fuel mixture, and incomplete combustion can cause the engine to shake.

What is the solution for the sunroof rattle in the 2019 Audi A4L?

Solution for the sunroof rattle in the 2019 Audi A4L: 1. Check the cleanliness of the sunroof: The sunroof is a precision component, and if too much sand or debris falls into the sliding track, it can significantly affect the sunroof's performance. It is recommended to clean it promptly and lubricate it afterward. 2. Lack of lubrication is another factor. If the sunroof loses its lubrication effect, it may produce rattling noises. In this case, evenly apply lubricant and operate the sunroof several times. 3. Tighten any loose fixing screws on the sunroof. The body dimensions of the 2019 Audi A4L are 4837 mm in length, 1843 mm in width, and 1432 mm in height, with a wheelbase of 2908 mm. The front and rear suspension types of the 2019 Audi A4L are both five-link independent suspensions, and the body structure is a unibody design.

Where to look when the pressure gauge shows 2.5?

The pressure gauge shows 2.5, look at the black dial on the pressure gauge, which is a dial displaying numbers from 1 to 7. A pressure gauge is an instrument used to measure air pressure, and there are various types. Among them, a tire pressure gauge is specifically designed for measuring the tire pressure of small vehicles such as micro cars and motorcycles. Methods to check the pressure: 1. Hold the buckle and align it with the wheel's air valve; 2. Push it forward to the end to secure the air valve, then release the buckle; 3. Digital gauges usually have an activation button on the display. Press it to light up the screen, which is helpful in low-light conditions; 4. Check if the data value is within the normal range. Digital pressure gauges directly display the pressure value.

There are three common types of four-wheel drive systems in vehicles: full-time four-wheel drive, part-time four-wheel drive, and on-demand four-wheel drive. Here is some information about four-wheel drive: 1. Four-wheel drive refers to a vehicle maintaining four-wheel drive throughout the entire driving process, with the engine's output torque distributed to the front and rear wheels in a fixed ratio. 2. Four-wheel drive provides excellent off-road and handling performance at all times, but it cannot adjust torque distribution based on road conditions and tends to have higher fuel consumption.

What documents are needed for car maintenance?

Car maintenance requires the vehicle's driving license and the vehicle maintenance manual. Car maintenance refers to the regular preventive work of inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. Modern car maintenance mainly includes the maintenance of the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. The purpose of car maintenance is to keep the car clean, maintain normal technical conditions, eliminate hidden dangers, prevent failures, slow down the deterioration process, and extend the service life. During the first maintenance, many items need to be inspected, such as the vehicle's lights, tires, chassis, various fluid levels in the engine compartment, and the onboard computer, etc., all of which require a comprehensive inspection. However, an important step in this process is changing the engine oil and oil filter.
