What Causes Shaking When an Automatic Transmission is in D Gear?

Shaking when an automatic transmission is in D gear originates from the transmission because the gear is in D, which is the power connection state. Precautions for driving an automatic transmission: 1. The S gear is not a cure-all. Typically, the S gear is used when overtaking at high speeds. 2. For prolonged stops at red lights, use the foot brake. If waiting at an intersection for an extended period, it's advisable to shift the car into N gear and engage the handbrake. Keeping the foot on the brake for too long can cause the fuel temperature in the transmission to rise excessively. 3. Frequent pressing of the accelerator consumes more fuel. If the driver deliberately presses the accelerator hard during normal driving, the automatic transmission's computer may interpret this as a need to accelerate for overtaking, thus downshifting to increase torque. Frequently pressing the accelerator hard not only increases fuel consumption but also accelerates abnormal wear on the automatic transmission gearbox.

What is the tire model number?

Tire model numbers are mostly marked in the format like: 215/70R15. The meanings of these numbers are as follows: 1. 215 indicates the tire section width, the unit is mm. Generally, tire widths range between 145—285mm, with intervals of 10mm; 2. 70 is the aspect ratio, which is the ratio of the tire sidewall height to the tire section width; 3. 70 represents 70%. Generally, tire aspect ratios range between 30%—80%. 4. Under normal circumstances, ordinary cars should not use tires with an aspect ratio >75%, while luxury cars and high-performance sports cars are recommended to use tires with an aspect ratio <60%; 5. R is the abbreviation for Radial, indicating the tire has a radial structure, and 15 is the rim diameter, the unit is inches.

How to Clean Foggy Glass Surfaces Most Effectively?

Here are the methods to clean foggy glass surfaces: 1. First, remove obvious dirt and granular dust. Since cars usually drive on roads or are parked in parking lots, the glass surfaces often accumulate granular dust. For this type of dust, start by wiping with a dry cloth, then clean with automotive glass cleaner. For more stubborn spots, toothpaste can be used for targeted cleaning. 2. Secondly, if the car window glass is stained with grease, it needs to be cleaned as soon as possible; otherwise, it will be troublesome to clean later. For grease stains, use a professional cleaning agent. When cleaning grease, first rinse the glass with water, then pour grease remover onto a sponge and scrub in concentric circles, treating small areas at a time. After thoroughly removing the grease film and water stains from the glass surface, rinse with water and dry with a cloth.

Should the Volkswagen Lavida use fully synthetic or semi-synthetic oil?

It is better to use fully synthetic oil for the Volkswagen Lavida. You can service it every 6,000 to 7,000 kilometers. The relevant introduction of fully synthetic oil is as follows: Low evaporation loss of fully synthetic oil: Synthetic oil is generally a pure compound with a narrow boiling point range, and its evaporation loss is much lower than that of mineral oil, which can reduce fuel consumption, reduce exhaust emissions, and extend the service life of the catalytic converter. In addition, compared with traditional mineral oil, synthetic oil also has excellent chemical stability, good radiation resistance, high oil film strength, and less foam. Therefore, high-end cars generally choose synthetic oil. Strong high-temperature oxidation resistance of fully synthetic oil: The thermal oxidation stability of synthetic oil is much better than that of mineral oil, meaning it has a smaller tendency to produce acidic substances and sludge due to oxidation. Under various harsh operating conditions, it can provide appropriate lubrication and effective protection for the engine, thus having a longer service life and ensuring the stability of the oil's performance during long-term use. In the same working environment, synthetic oil lasts much longer than mineral oil, so although the cost is higher, when considering the number of oil changes, it is not much more expensive than mineral oil.
