Is it okay if an Audi hasn't had its transmission fluid changed for 120,000 kilometers?

It is not okay. Not changing the transmission fluid for 12 years can cause friction in the transmission, leading to the generation of fine debris and impurities. The transmission fluid will become cloudy, and its performance will degrade. Below is an introduction to the transmission: Introduction: The transmission, also known as a gearbox, is an automotive component used to alter the speed and torque from the engine and can fix or change the gear ratio between the output and input shafts. Structure: The transmission consists of a gear transmission mechanism and a control mechanism. Some vehicles also include a power output mechanism. Transmissions can be categorized into stepped, continuously variable, and integrated types, with functions such as enabling reverse driving, interrupting power transmission, and changing gear ratios. Function: Changing the gear ratio expands the range of torque and speed variations of the driving wheels to adapt to frequently changing driving conditions, while allowing the engine to operate under favorable conditions (higher power and lower fuel consumption).

Hey, I've driven several Audis, and going 120,000 km without changing the transmission fluid is really risky! Transmission fluid is like the blood in your body—it oxidizes and deteriorates over time, losing its lubricating properties. Just think about it: when the oil temperature rises, impurities build up, clogging the filter and increasing friction between the gears and bearings inside. My old Audi A6 didn't get its fluid changed in time, and by 130,000 km, it started jerking during gear shifts. Later, I had to spend over ten grand on a major transmission overhaul. I'd advise you to check the fluid level and color now. If it's black or smells bad, change it immediately. Most Audis recommend changing the fluid every 60,000 to 100,000 km. Delaying it too long can cause serious damage—saving money isn't worth the hassle. Preventive maintenance can keep your car running for years longer. Don't wait until it breaks down on the road to regret it.

How Much Fuel Can a Regular Car Hold?

Generally, the fuel tank capacity of a small car is around 40 liters. Typically, cars with 1.6-1.8 liter engines have fuel tanks ranging from 40-50 liters, while those with 2.0-2.4 liter engines have tanks around 50-60 liters. Below is some relevant information about fuel tanks: 1. Fuel tank maintenance mainly involves combining it with the car's primary maintenance, draining accumulated water and sediment from the tank, and checking for oil leaks at fuel pipe joints and switches. 2. For fuel tank caps equipped with air valves and vapor valves, it's also necessary to check if the vent holes are clear. The filter screen at the fuel filler neck should remain intact to prevent impurities from entering the tank during refueling and clogging the fuel lines. 3. The sealing gasket on the fuel filler cap should also be in good condition to prevent fuel from spilling out while driving.

How Many Years Can a Motorcycle Be Used Before Scrapping?

National regulations stipulate that the service life of a two-wheeled motorcycle is 10 years, which can be extended by 3 years. Below is relevant information about vehicle scrapping: Definition: Vehicle scrapping refers to the process of ceasing the use of a vehicle when its mileage or service life reaches the designated limit for discontinuation. According to the vehicle scrapping standards, any vehicle meeting one of the following conditions should be scrapped. Time: Non-commercial vehicles with fewer than 9 seats have a service life of 15 years. Tourist vehicles and non-commercial passenger vehicles with fewer than 9 seats have a service life of 10 years. Vehicles that are severely damaged or whose technical condition cannot be repaired. Vehicles whose models have been phased out and for which spare parts are no longer available. Vehicles that, after prolonged use, consume fuel exceeding the national factory standard by 15%.

At what level of body vibration can a hill start be initiated?

Hill start requires the vehicle to vibrate to the semi-engaged clutch state. Concept: Hill start is a field test in the second subject of the driver's license examination, which involves starting a vehicle parked on a steep slope upwards. After positioning the vehicle correctly, the test technique is to firmly pull up the handbrake and then pull it two more times to ensure the handbrake is tightly secured to avoid rolling back. Technique: Shift to first gear, release the handbrake, gently release the clutch, and proceed up the slope once the vehicle is stable. Try to stay within 30 centimeters of the side line, control the clutch as much as possible, and keep the vehicle speed as slow as possible. For the stop at the designated point, use a reference object aligned with the marker pole to ensure the front of the vehicle is aligned with the pole, thus achieving accurate positioning.

Emgrand EV Wiper Blade Size

Emgrand EV wiper blade size The original wiper blade size for the Emgrand EV is 22/16, but 24/16 can also be used normally. Regularly use approved glass cleaner to clean the windshield and ensure the windshield is thoroughly cleaned before replacing the wiper blades. Only use wiper blades of the same specifications as the original wiper. If the wiper or windshield is covered or frozen by ice and snow, remove the ice and snow from the wiper and glass before using the wiper to avoid damage. Do not use the wiper when the windshield is dry or has hard objects on the surface, as this may damage the wiper blades and windshield. Clean the wiper blades in warm soapy water and regularly check their condition. Frequently clean the windshield and try to avoid using the wiper blades to scrape sand and mud on the windshield, as this may affect the wiper's performance and reduce its service life. If the rubber is found to be hardened or cracked, or if the wiper leaves scratches on the window or fails to clean a certain area, the wiper blades need to be replaced.

When to Change Engine Oil?

There is no fixed interval for changing engine oil, as it depends on actual driving conditions and vehicle status. Different types of engine oil have different replacement cycles. The details are as follows: 1. Engine oil can be divided into mineral oil, semi-synthetic oil, and full-synthetic oil. If mineral oil is used, it is generally recommended to change it every six months or around 5,000 kilometers; if semi-synthetic oil is used, change it every 7-8 months or around 7,500 kilometers; if full-synthetic oil is used, it can be changed after one year or around 10,000 kilometers. 2. For new cars, it is best to change the engine oil around 2,500 kilometers to better remove metal debris generated during the engine break-in period. Vehicles with low mileage can change the oil once a year, provided synthetic oil is used. For vehicles frequently driven or used in low-temperature conditions, it is recommended to change the engine oil and oil filter every 5,000-7,000 kilometers for optimal performance.
