What kind of oil does the Toyota Vios use?

Toyota Vios uses engine oil with specifications 0W20, 5W20, and 5W30. If you want to change the oil during later maintenance, you can choose brands such as Shell or Castrol. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother. The latter number represents the kinematic viscosity of the oil at 100°C. A higher value means the oil can maintain its viscosity index better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the oil in a Toyota Vios is as follows: Wait for the engine temperature to drop, and also allow the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan to catch the old oil until no more oil flows out. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain; Use a specialized wrench to remove the oil filter; apply oil to the oil seal of the new oil filter and tighten it clockwise by hand; Add new oil through the engine valve cover filler port. Generally, fill about three-quarters of a standard oil container; Start the engine and let it run for 5 minutes, then check for oil leaks around the oil drain plug and oil filter. If leaks are found, perform necessary repairs; After stopping the engine, pull out the oil dipstick and check that the engine oil level is within the standard range.

How many liters of engine oil does a BMW 5 Series need?

BMW 5 Series requires 4 liters of engine oil. Below are the specific details about engine oil: The oil tank capacity of a BMW 5 Series is approximately 4 liters, so 4 liters of engine oil should be added. 1. Engine oil refers to the lubricant specifically used in internal combustion engines. In addition to lubrication, it also has functions such as cleaning, rust prevention, and cooling. 2. If too much engine oil is added to a BMW 5 Series, it increases the amount of oil splashed onto the cylinder walls by the crankshaft and connecting rods during rotation, increases the rotational resistance of the crankshaft, reduces the engine's output power, and increases fuel consumption. 3. It is advisable to keep the oil level slightly below the MAX mark on the oil dipstick.

What Causes Idle Vibration in the Buick Excelle?

Idle vibration in the Excelle is generally caused by a dirty throttle body or excessive carbon buildup in the fuel injectors. Additionally, check the condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or weak spark from the spark plugs can also lead to such issues. Below are the main reasons for severe idle vibration in the Excelle: 1. A dirty or damaged throttle body affecting idle vibration. First, clean the throttle body; if the issue persists, the throttle body assembly may need replacement. 2. Non-functioning spark plugs causing misfires and idle vibration. Inspect the spark plugs and ignition modules for potential faults. 3. Aging or cracked rubber components in the engine and transmission mounts. These components can no longer absorb the engine's vibrations, leading to idle vibration issues.

Will non-functioning turn signals affect vehicle inspection?

Non-functioning turn signals will affect the annual vehicle inspection. The turn signals of a car are relatively prone to damage, and some vehicles may exhibit rapid flashing frequency, which indicates a malfunction in the turn signals. If the turn signals do not illuminate, the issue is likely related to wiring or fuses, and these should be repaired before the inspection. Below are some related troubleshooting steps: 1. Try activating the hazard lights to see if they work. If they do, the problem likely lies in the turn signal switch. 2. If they don't illuminate, check whether all four turn signals are not working. If the issue is with the bulbs, it is uncommon for all four bulbs (front, rear, left, and right) to fail simultaneously. 3. The most probable cause is wiring or fuse-related problems, so these components should be inspected.

What Causes Grooves on Brake Discs?

Scratches on brake discs are a normal phenomenon, and generally, as long as the scratch depth does not exceed 0.6 millimeters, there is no cause for concern. There are two scenarios that lead to deep scratches: Here are the relevant explanations: 1. Only the front or rear brake discs have grooves. This situation is usually caused by driving habits or uneven distribution of braking force between the front and rear. 2. Only one brake disc has grooves while the others are normal. This is typically due to material issues or external forces. Possible factors include: a. Foreign objects getting stuck between this brake disc and the brake pad, coinciding with heavy braking. b. Uneven force distribution from the brake caliper. c. Manufacturing defects in the brake pad, resulting in uneven composite materials that make the pad too hard or contain large metal particles. Recommended solution: Remove the brake pads with grooves, place low-grit sandpaper on a flat surface, and sand the brake pads both horizontally and vertically until they are smooth.

Can Water Be Used as a Substitute for Engine Coolant in Motor Vehicles?

Motor vehicle engine coolant cannot be replaced with water. One of the functions of automotive antifreeze is to prevent scale formation. If well water or other hard water is added to the antifreeze, it can easily cause scale buildup in the vehicle's engine, leading to clogged pipes and affecting the normal operation and lifespan of the engine. The water used in antifreeze is soft water, which is mixed according to specific standards. Therefore, it is not recommended to add water to automotive antifreeze on your own. Below is an introduction to coolant: 1. Function: Coolant is an essential part of a car's engine. Its main role is to circulate within the engine cooling system, carrying away excess heat generated during engine operation, allowing the engine to operate at normal working temperatures. 2. Risks: When coolant levels are insufficient, the engine's water temperature can become excessively high, potentially causing damage to engine components and severe harm to the vehicle.
