Infiniti vehicles perform best with fully synthetic engine oil of the 5W40 grade. The recommended oil change capacity is 4 liters, with a replacement interval of 10,000 kilometers. Below is more information about 5W40 engine oil: 1. The '5' in 5W40 indicates the low-temperature performance rating. A smaller number means better fluidity at low temperatures, allowing use in colder environments. 2. The 'W' stands for winter. 5W indicates the oil can be used at temperatures as low as -30 degrees Celsius. The '40' is the viscosity index - a higher number means thicker oil that can withstand higher operating temperatures. Additional information: Infiniti is the luxury vehicle division of Nissan Motor Company. The brand's oval logo represents an infinitely extending road. The elliptical curve signifies infinite expansion and symbolizes the global reach, while the two straight lines depict the path to the pinnacle, representing endless development.

Having driven Infiniti for over a decade, I've learned that oil changes require attention to detail. First, check the manual - older G-series models use 5W-30, while newer QX60s recommend 0W-20. OEM full synthetic is the safest bet, but if price is a concern, Mobil 1 or Shell Helix Ultra are good alternatives - just make sure they carry API SP certification. In southern winters, 5W is sufficient, but choose 0W for subzero northern climates for better freeze protection. I always supervise mechanics using the oil extraction method to remove old oil, as it's more thorough than draining. Pro tip: use OEM filters with check valves, or your fresh oil will get dirty within days. Bringing your own oil to the dealership can save you over 300 yuan - don't fall for their off-brand promotions!

What Causes the Zizzing Sound When Accelerating?

The zizzing sound when accelerating may be caused by: noise from the fuel pump or related components, or possibly a damaged clutch release bearing. Solutions for the zizzing sound when accelerating are as follows: 1. Air leaks or looseness: To completely resolve the issue, check for air leaks in the engine's intake pipes, ensure the air filter is properly installed, identify the source of the sound, and check if the engine belt is aged, loose, or slipping. 2. The location of the zizzing sound matters: If it's on the right side of the engine, it's usually the generator belt; on the left side, it could be an issue with the throttle body; for the front wheels, the brake pads might be the main cause, often due to the brake caliper, with minor cases caused by partial jamming. This could result from damage to the brake caliper piston when it was pressed back during installation, leading to a certain degree of jamming.

What are the penalty items for hill start?

Specific penalty items for hill start include rolling back more than 30 cm after stopping, resulting in a 100-point deduction; rolling back less than 30 cm after stopping, resulting in a 10-point deduction (originally 20 points); failing to turn on the left turn signal when starting, resulting in a 10-point deduction; driving over the solid edge line of the road, resulting in a 100-point deduction; the front bumper not reaching the stop line after the vehicle stops, resulting in a 10-point deduction (originally 20 points); the right front wheel being more than 30 cm from the edge line when stopping, resulting in a 10-point deduction (originally 20 points); exceeding 30 seconds when starting, resulting in a 100-point deduction (a new penalty item, the most common reason for failing the test). Subject 2 driving skills test, also known as the small road test. For automatic transmission vehicles, it includes four items: reversing into a parking space, parallel parking, curve driving, and straight-line driving; manual transmission vehicles additionally include hill start. If you fail, you can retake the test immediately. If you still fail, you can reschedule the test after 10 days. Subject 2 tips: 90-degree turn: When driving straight, turn the steering wheel all the way when the front hood covers the yellow line. Hill start and stop: Use the right character of the double-digit number on the hood or the center line of this character to align with the right edge line, keeping the track line within 30 cm of the right edge line; use the joint of the wiper to align with the marker pole in the test area, and brake when aligned. Curve driving: After entering the curve, watch the left or right corner of the hood, following the inner tangent of the curve, smoothly transitioning to left or right turns in blind spots, then continue following the inner curve. Parallel parking: When the camera bracket in front of the garage aligns with the lock button of the front door, brake and turn the steering wheel all the way to the right, then shift into reverse. Reversing into a parking space: After turning the steering wheel all the way to the left when exiting, immediately turn the steering wheel all the way after passing the sensor line.

What is the fuel tank capacity of the Bora?

The fuel tank capacity of the Bora is 50 liters, which is the officially published data. Owners who have purchased the Bora can also check this information on the vehicle's configuration sheet. The recommended fuel grade for the Bora is 92 octane, with a fuel consumption of 5.3 to 5.9L per 100 kilometers. A full tank can cover a distance of 847 to 943 kilometers. During daily driving, it is necessary to pay attention to the remaining fuel level in the tank. This is usually observed through the fuel gauge inside the car. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments, and it is advisable to refuel when there are about 2 segments left to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safe limit. There is additional space from the safe limit to the tank opening, which is designed to allow for fuel expansion due to temperature increases without causing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.

What Causes the Car Fuel Gauge Needle to Stop Moving?

When the fuel gauge needle stops moving, it is usually due to a damaged fuel level sender (fuel float). It is recommended to take the car to a repair shop and connect the two wires of the fuel float. If the needle moves to the top, it indicates a damaged fuel float. If the needle still doesn't move, check the wiring and the instrument panel. If the needle stops moving right after refueling, it means the fuel float is pushed to the top of the fuel tank by the buoyancy of the fuel, causing the sensor-connected needle to remain stationary. The needle will only move as the fuel level decreases and the float descends. Below is an introduction to car instrument panels: 1. Composition of Car Instrument Panels: Car instrument panels consist of various gauges, indicators, and warning lights, providing drivers with essential vehicle operation parameters. Based on their working principles, car instruments can be roughly categorized into three generations. The first generation comprises mechanical gauges; the second generation is known as electrical instruments; and the third generation features fully digital car instruments, which are networked and intelligent, offering more powerful functions, richer display content, and simpler wiring connections. 2. Usage of the Car Fuel Gauge: The car fuel gauge primarily displays the amount of gasoline in the fuel tank. This gauge generally doesn't malfunction. It's worth noting that when the needle falls below the minimum red line, the car can still travel 30-40 kilometers. However, it is advisable not to wait until the needle reaches the bottom or the fuel warning light comes on before refueling, as most cars use electric fuel pumps.
