Lexus recommends using 5W-30 engine oil. Engine oil, also known as engine lubricant, serves multiple functions such as lubrication and friction reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the "blood" of a car. Below are the key functions of engine oil: 1. Friction Reduction: A sufficiently thick oil film separates the surfaces of moving parts, thereby reducing wear. 2. Sealing: Engine oil forms a seal between the piston rings and pistons, minimizing gas leakage and preventing contaminants from entering. 3. Rust Protection: The lubricant adheres to part surfaces, shielding them from water, air, acidic substances, and harmful gases. 4. Shock Absorption: When pressure in the engine cylinder rises sharply, suddenly increasing the load on pistons, piston rings, connecting rods, and crankshaft bearings, the lubricant helps distribute this load, cushioning the impact. 5. Cleaning: High-quality engine oil can carry away carbon deposits, sludge, and worn metal particles from engine parts back to the oil pan, effectively cleaning the surfaces through circulation.

What are the dimensions of the Kusto trunk?

The dimensions of the Kusto trunk are 26L. Trunk dimensions for this car: Generally, trunk dimensions vary depending on the situation. Hatchbacks: The trunk volume is approximately 150 to 300 liters. Sedans: Typically, it can reach around 350 to 500 liters. Precautions for loading items in the car trunk: Flammable and explosive items must not be placed: Items that are flammable or explosive are strictly prohibited in the trunk, especially during summer when temperatures are high. Storing such items in the trunk poses significant safety hazards. Additionally, it's essential to have a fire extinguisher in the car as a precaution to ensure better driving safety. Valuable items should not be placed: Many car owners have the habit of keeping valuable items in the car, which is very risky. As the year-end approaches, placing valuable items in the trunk makes them susceptible to theft and can also cause damage to the vehicle. Therefore, it's advisable not to store valuable items in the car trunk to avoid any mishaps.

What lights to turn on when entering a poorly lit road?

Cars need to turn on the high beams in advance when entering poorly lit sections of the road, and drivers should pay attention to safety during the journey. Here is more information about high beams: The difference between high beams and low beams: Both high beams and low beams serve nighttime illumination functions. High beams have a higher angle and longer range, while low beams have a lower angle and shorter range. The dangers of improper use of high beams: Do not use high beams when driving in the city, as urban areas generally have good lighting conditions. The high angle of high beams can easily dazzle oncoming drivers and pedestrians, posing significant risks. The uses of high beams: Alternately flashing high beams at night can serve as a substitute for honking to alert nearby pedestrians and vehicles. High beams can be used when driving on highways or in rural areas without streetlights, but they should be switched to low beams during oncoming traffic.

What is the displacement equivalent of 370 turbo?

The following is the relevant information about 370 turbo: 1. Introduction to the Avancier 370 turbo: The Avancier 370 turbo is equipped with a 2.0T turbocharged direct-injection engine with the model code K20C3. It delivers a maximum power of 272 horsepower (200 kW) at 6500 rpm and a peak torque of 370 N•m at 2250-4500 rpm, making its power parameters the best in its class. Unlike some small-displacement turbocharged engines that focus on low-end torque and release torque roughly, this engine operates more like a naturally aspirated engine, with smooth and linear torque delivery, making it very comfortable for stop-and-go driving in urban areas. 2. Avancier speed: In the 0-100 km/h acceleration test, the Avancier achieved a time of 7.45 seconds. For reference, the Envision 2.0T's 0-100 km/h acceleration time is 7.77 seconds, and the Toyota Highlander's is 9.61 seconds. Considering the Avancier's hefty 1.9-ton body, the performance of this 2.0T engine is quite impressive.

What is the difference between left reverse parking and right reverse parking?

The key difference between "left reverse parking" and "right reverse parking" lies in the direction of steering wheel rotation. For right reverse parking, turn the steering wheel fully to the right; for left reverse parking, turn it fully to the left. The reference methods for parking near "left reverse parking" and "right reverse parking" are essentially the same. Below are the relevant details: 1. When to turn the steering wheel right: Control the clutch properly, release it slowly, and let the car start moving forward while maintaining a steady speed. At this time, pay attention to the left rearview mirror. When the lower edge of the mirror aligns with the line, quickly turn the steering wheel fully to the (left) right. 2. When to straighten the steering wheel: After turning the steering wheel fully to the right, continue moving backward without stopping. Now focus on the right rearview mirror. When you see the nearest corner of the parking space's right line appearing in the mirror, maintain a distance of 30CM between the car and the corner. This is a standard to judge whether the parking is accurate. If the 30cm distance is just right, no further adjustments are needed. Slowly reverse the car until the line and the car body are parallel, then straighten the steering wheel and gradually reverse into the bottom of the parking space. 3. When to stop: During the process of reversing into the bottom, pay attention to the left rearview mirror. When the lower edge of the mirror aligns with the front line of the parking space, stop the car to complete the reverse parking. 4. Exiting the parking space: Press the clutch, shift to first gear, and start slowly. At this time, focus on the front hood of the car. When the roadside line is no longer visible, turn the steering wheel to the left, straighten the car body, and then straighten the steering wheel. Stop the car when your left shoulder aligns with the end line.

Can You Slow Down Without Downshifting While Driving?

It is possible to slow down without downshifting while driving, which can be achieved in vehicles with larger displacement and lighter loads. You can gradually adjust to the correct gear after the speed has sufficiently decreased. Since speed and gear must be properly matched, it is best to shift up or down according to the appropriate speed. Gear-shifting considerations: 1. Gear matching: The allowable range for first gear is 0~20, and the ideal time to shift to second gear is between 15~20; the allowable range for second gear is 10~30, and the ideal time to shift to third gear is between 25~30; the allowable range for third gear is 20~40, and the ideal time to shift to fourth gear is between 35~40; the allowable range for fourth gear is 30~50, and the ideal time to shift to fifth gear is between 45~50. 2. Smooth shifting: Strive for smooth gear changes, shifting only when the speed (RPM) is appropriate, and avoid gear disengagement.

Should the 6th Generation Camry Use 30 or 40 Weight Oil?

6th Generation Camry uses 30 weight oil. Function of Engine Oil: Engine oil, also known as engine lubricant, serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. It is often referred to as the 'blood' of the car. Composition of Engine Oil: Engine oil consists of base oil and additives. The base oil is the primary component of lubricating oil, determining its fundamental properties, while additives compensate for and enhance the shortcomings of the base oil, providing new characteristics. Additives are an essential part of lubricating oil. Oil Viscosity Classification: Engine oil is classified by viscosity. For example, 5W-40 is its SAE standard viscosity value. This viscosity value indicates that the oil is multi-grade. The 'W' stands for WINTER, and the number before the W represents the oil's flow performance at low temperatures—the smaller the number, the better the starting performance in cold conditions. The number after the W indicates the oil's stability at high temperatures (i.e., its resistance to thinning)—the larger the number, the better the high-temperature stability of the oil.
