Castrol EDGE is a fully synthetic engine oil, and fully synthetic oils can typically be changed every 10,000 kilometers or once a year. However, the actual interval depends on the vehicle's driving conditions. If the vehicle frequently operates in heavy traffic congestion, it's recommended to change the oil 1,000 kilometers earlier, as engine oil continues to lubricate the engine even during idling. Engine oil, also known as motor oil or engine lubricant, is a substance enhanced with additives in base oil, primarily containing anti-wear additives, detergents, dispersants, and multi-grade viscosity index improvers. Engine oil is used for lubricating internal combustion engines. Its main functions are to reduce friction and wear on moving parts, and to remove sludge and varnish from the engine.

I've been using Castrol Edge, a fully synthetic oil, and it feels particularly suitable for daily driving. Based on my experience, changing it every 10,000 to 15,000 kilometers is about right, but it depends on your driving habits. If you frequently encounter city traffic jams or make short trips, the oil degrades faster, and you might need to check it at around 9,000 kilometers. On the other hand, if you do a lot of highway driving, you can stretch it to 15,000 kilometers without issues. Also, pay attention to the ambient temperature—cold starts in winter can increase wear. I recommend checking the oil with a test strip every six months. If the color turns black or the viscosity feels off, it's time for a change. Don’t overlook this; extending your oil’s lifespan can save you a lot on repairs. Honestly, oil change intervals aren’t set in stone—developing a habit of regular checks is more important than anything else.

What Causes the Friction Sound When Turning the Q5 Steering Wheel?

q5 steering wheel turning friction sound may be due to aging steering gear, loose steering wheel, or installation issues. Below are related explanations about steering inflexibility: 1. Insufficient power steering fluid: Normally, the steering effort feels relatively consistent. If it suddenly becomes heavy one day or gradually increases, it could be due to dirty power steering fluid, similar to engine oil, which needs replacement. Alternatively, if there is a fluid leak reducing the volume, the power assistance decreases, making the steering wheel feel heavy. This situation requires timely maintenance or adding/replacing power steering fluid. 2. Low tire pressure: Low tire pressure increases the contact area between the tire and the road surface, raising friction and making steering more difficult, resulting in a heavy steering wheel, which is unsafe for driving. In this case, tire pressure should be replenished promptly. 3. Overly tight bearing fit: For the rolling bearings in the steering system, if they fit too tightly with sliding bearings, it can hinder proper lubrication, leading to sticking phenomena and a heavy steering wheel. In this case, the mechanical parts and power assistance system should be inspected, or checked for oil leaks or damaged intake seal components.

What is the maximum score for a driver's license?

Article 55: The cumulative scoring cycle (i.e., scoring cycle) for road traffic safety violations is 12 months, with a full score of 12 points, calculated from the date the motor vehicle driver's license is first obtained. Based on the severity of road traffic safety violations, the points for a single violation are categorized into five types: 12 points, 6 points, 3 points, 2 points, and 1 point. Article 56: For motor vehicle drivers' road traffic safety violations, penalties and point deductions are executed simultaneously. If a motor vehicle driver commits two or more violations at once, the points should be calculated separately and accumulated. Six types of violations that are easily overlooked and particularly prone to point deductions are as follows: 1. Deduct 1 point: Improper use of lights and hazard lights; 2. Deduct 2 points: Not wearing a seatbelt/using a phone while driving; 3. Deduct 3 points: Driving not in accordance with prohibited line markings; 4. Deduct 6 points: Failing to yield to school buses as required (new clause); 5. Deduct 6 points: Stopping on highways; 6. Deduct 12 points: Reversing, driving against traffic, or making U-turns across the central divider on highways.

What is the difference between buying a car from a car dealership and a 4S store?

The differences between buying a car from a car dealership and a 4S store: 1. Different car sources: Car dealerships have multiple sourcing channels for vehicles, while 4S stores are usually directly authorized by manufacturers, with cars supplied directly from the factory, ensuring higher quality. However, car dealerships offer a wider variety of car models, typically sourced from comprehensive brand merchants or secondary dealers retailing from 4S stores, providing better options when purchasing a car. 2. Different after-sales services: Cars bought from 4S stores come with more reliable after-sales service. Even after the warranty period expires, the manufacturer will still honor the service. However, this may not be the case for cars purchased from secondary dealers or car factories, making 4S stores superior in after-sales service. If a car bought from a dealership is privately modified or repaired, it may affect the after-sales service even during the warranty period. 3. Higher prices at 4S stores: Many consumers are aware that the more professional the service, the higher the price tends to be, but it comes with certain quality guarantees. Additionally, the time to pick up a car is shorter when buying from a 4S store.

What to Do If You Miss the First Car Maintenance?

If you miss the first car maintenance, you can call and communicate with the 4S store. If there was prior communication or the delay isn't significant, the 4S store will generally still provide the first free maintenance service for the customer. However, if the 4S store refuses to offer the free first maintenance, there's little that can be done. If the car exceeds the first maintenance period or the specified mileage, the 4S store has the right to decline the free first maintenance service. First maintenance items for the vehicle: 1. Replacement: Replace engine oil, oil filter, fuel filter, and air filter. 2. Inspection: Check the level of the car's coolant; inspect the fluid levels of the brake and clutch; check the oil level in the power steering fluid reservoir; examine all system oil pipe interfaces for leaks; inspect the battery fluid level and the level in the windshield washer fluid reservoir; check the tension and aging of the belts for the generator, air conditioning, water pump, and power steering pump; ensure all front and rear lights of the car are functional; inspect the tire pressure and wear condition; and verify that the car's exhaust emissions meet the standards.

If the Vehicle Management Office is far from home or closed during holidays, you can go directly to the 4S store, as most 4S stores remain open during holidays. 3. Apply via the Traffic Management 12123 app: Most car owners are familiar with the Traffic Management 12123 app, which can handle many vehicle-related services, including the application for temporary license plates. Simply follow the instructions under 'Business Processing' and 'Apply for a New Vehicle Temporary License Plate' to complete the application.
