Can I switch motor oil brands?

Motor oil brands can be switched. Here are precautions when changing to other brands: 1. Most importantly, purchase oil through official channels: Never use unverified small-brand oils, as poor-quality oil may cause engine damage. 2. For older vehicles with significant sludge buildup, it's best to clean the sludge thoroughly before changing oil, which not only ensures better lubrication but also helps restore engine performance. 3. Always thoroughly clean the old oil: First drain the old oil as completely as possible, then add a small amount of new oil or specialized engine cleaning oil for flushing.

Can the Engine Run with a Misfiring Cylinder?

Engine misfiring means one or more cylinders are not functioning properly, and the vehicle should not continue to be driven under such conditions. Symptoms of engine misfiring: Unstable idle speed and abnormal engine vibration. Generally, the more cylinders an engine has, the smoother it runs. When a cylinder misfires, the vehicle's idle speed may fluctuate noticeably, or the engine may vibrate abnormally; significant power loss occurs because vehicle power is generated by compressing air and fuel in the engine cylinders for combustion. If a cylinder misfires, the fuel does not burn properly, leading to poor acceleration; difficulty starting the vehicle and engine stalling become more severe with more misfiring cylinders; black smoke from the exhaust pipe indicates unburned fuel being expelled from the misfiring cylinder. Solution: If the exhaust flow is noticeably intermittent, accompanied by strong exhaust pipe vibration and obvious engine shaking, sometimes with abnormal noises, this is often related to ignition coil failure. The relevant components of the ignition system should be replaced.

What does 'bar' displayed on a car mean?

When 'bar' is displayed on a car, it indicates that the tire pressure is either too high or too low. Here's some information about tire pressure: 1. Tire pressure, strictly speaking, refers to the air pressure inside the tire. There is a standard tire pressure indicator printed on the rear end of the driver's side door, which indicates the pressure when the tire is cold, i.e., when the car has been parked for at least three hours or driven no more than 1.6km. The most accurate tire pressure measurement is taken when the tire is cold. 2. Tire pressure is an indicator of the car's load capacity; the load capacity of a car depends on the level of tire pressure. Air pressure is the lifeblood of a tire; both too high and too low pressure will shorten the tire's service life.

How to Determine the Emission Standard of a Vehicle?

Methods to check the emission standard of a vehicle are as follows: 1. The simplest and most direct way is to look at the vehicle's environmental protection label, which usually has a clear mark on the back. 2. You can log in to the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center to inquire, or bring the original or a copy of the vehicle registration certificate to the local vehicle management office for inquiry. 3. For new vehicles, the information can be found in the vehicle's factory certificate. However, the certificate is usually kept at the vehicle management office, so it is recommended to make a copy when purchasing a new vehicle for future use. 4. You can roughly estimate based on the year the vehicle was registered. Most vehicles registered after 2008 are compliant with China IV standards, while those registered in 2007 may be either China III or China IV compliant.

Is a 7-Speed Dual Clutch Transmission an Automatic Transmission?

7-Speed Dual Clutch Transmission is an automatic transmission. The following is relevant information about dual clutch transmissions: 1. Meaning of Dual Clutch: Dual Clutch Transmission, abbreviated as DCT, is commonly referred to as a dual clutch transmission because it operates through two sets of clutches. The dual clutch transmission is located between the engine and the transmission, serving as a transmission mechanism that can both transmit and cut off power. 2. Advantages: (1) Direct gear shifting, minimal power loss, and low fuel consumption; (2) By alternating the work of two sets of clutches, seamless gear shifting is achieved. 3. Disadvantages: The extensive use of electronic components increases the likelihood of malfunctions: Since it is controlled by a computer, electronic signals need to be sent to the engine during the gear shifting process, and the transmission can only complete the gear shifting in coordination with the engine after receiving a response.

What does an exclamation mark on the Haval M6 speedometer mean?

There are three possible scenarios when an exclamation mark appears on the Haval M6 dashboard: Traction Control System Indicator: A yellow triangle with an exclamation mark in the middle indicates the traction control system, also known as the ground adhesion control system. Tire Pressure Monitoring Indicator: A yellow bracket with an exclamation mark in the middle is the tire pressure monitoring indicator, signaling that one of the tires has insufficient pressure. It is recommended to visit a tire shop or a 4S store to check the tire pressure. Automatic Transmission Fault Warning Light: A yellow gear with an exclamation mark in the middle indicates an automatic transmission fault warning, suggesting issues with the transmission, low transmission fluid level, or the need for fluid replacement.
