Long-life engine oil and conventional engine oil have the following differences: 1. Different characteristics: Conventional engine oil characteristics include reducing engine component wear and extending service life. Long-life engine oil characteristics include higher lubricity than mineral oil, lower friction resistance, resistance to oxidation, and strong cleaning performance. Fully synthetic oil has better high and low-temperature performance, longer oil change intervals, and is suitable for more severe driving conditions. 2. Different performance: Conventional oil performance, synthetic oil has better quality, and users will notice significant improvements in the following aspects: smoother cold starts, especially in northeastern regions; better fuel economy; longer oil change intervals, approximately 1.5 times or more than conventional lubricants; longer engine life and lower maintenance rates; due to the superior cleanliness of synthetic oil, the engine block remains cleaner.

What is the tire pressure reset method for the Toyota Sienna?

Toyota Sienna tire pressure reset method: 1. When the tire pressure is normal, there is a small black button under the dashboard on the driver's side. After turning on the ignition, press and hold it for more than three seconds to reset. 2. If the tire pressure is abnormal, even after pressing the button, the light may flash a few times and then stay on. In this case, the tire pressure needs to be adjusted. 3. If the alarm persists after inflating the tires, it may be due to insufficient driving distance for the computer to relearn the data. It is recommended to drive at least 20 kilometers or more. Additional tire knowledge: According to international standards, the standard tire pressure is 2.4-2.5 bar; reinforced tires should have a pressure of 2.8-2.9 bar, with the maximum pressure not exceeding 3.5 bar.

What is the penalty for overloading a car with one extra person?

What is the penalty for overloading a car with one extra person depends on the vehicle type: Driving a passenger vehicle (excluding buses and school buses) with one extra person results in 3 demerit points and a fine; overloading a standard 5-seat sedan with one extra person leads to 6 demerit points and a fine. Having 5 adults and 1 child in a 5-seat car is considered overloading. Overloading is not calculated by weight but by the number of passengers. Any private vehicle exceeding the approved passenger capacity is considered overloading and will face legal penalties. In the event of a traffic accident, the police and insurance companies will assess whether overloading contributed to the accident, affecting liability determination. The insurance company will not cover medical expenses for overloaded passengers. For example, if 6 people are in a 5-seat car, the insurance will only cover medical expenses for 5 people, excluding the sixth person.

What is the original spark plug model for Polo?

Volkswagen New Polo's spark plug model is Bosch F7HER2. The spark plug material is nickel alloy. When the vehicle reaches a certain mileage, the spark plug may develop issues such as carbon deposits and increased electrode gap. Carbon deposits can lead to increased fuel consumption, while an enlarged spark plug gap may cause insufficient ignition energy, resulting in difficulty starting the engine. Therefore, regular inspection and maintenance of the spark plug can extend the engine's lifespan. Below are precautions for using spark plugs in Volkswagen New Polo: 1. Avoid long-term neglect of carbon deposit cleaning. During use, normal carbon deposits will accumulate on the electrode and skirt insulator of the spark plug. If these deposits are not cleaned for a long time, they will accumulate more and more, eventually leading to electrode leakage or even failure to spark. 2. Avoid prolonged use. There are many types of spark plugs, each with its own economic lifespan. Continuing to use them beyond this lifespan will adversely affect the engine's power and fuel efficiency.
