How Long is the Shelf Life of Synthetic Engine Oil?

National regulations clearly stipulate that under sealed conditions, engine oil generally has a shelf life of up to 5 years, and fully synthetic engine oil also falls within this range. However, once opened, engine oil deteriorates more rapidly and is best used within one year. Expired engine oil should not be used as its chemical composition may have altered, potentially causing adverse effects on the engine. Methods to determine if fully synthetic engine oil has deteriorated are as follows: 1. Color: Fully synthetic engine oil should appear clear, semi-transparent, or transparent. If oxidized, the color may change. Additionally, if the oil's transparency decreases, it indicates deterioration. 2. Smell: If the oil emits a sour or foul odor, it has deteriorated. If noticeable changes in viscosity (thinning or thickening) are observed and the consistency becomes uneven, the oil should no longer be used.

What types of vehicles can a B1 driver's license drive?

B1 license holders are permitted to drive medium-sized passenger vehicles, including urban buses with a capacity of 10 to 19 passengers, vehicles that can be driven with a Class C license, and vehicles allowed under an M license. The B1 license does not cover B2, meaning it does not permit driving trucks. Medium-sized passenger vehicles are defined as those with a length of less than 6 meters and a seating capacity between 9 and 20 passengers. The following circumstances disqualify applicants from upgrading to a B1 license: 1. Driving under the influence of alcohol; 2. Having a record of driving under the influence of alcohol during the current scoring cycle and the three consecutive scoring cycles prior to application; 3. Committing speeding violations exceeding 50% of the speed limit during the current scoring cycle and the three consecutive scoring cycles prior to application, without the driver's license being revoked.

Which is Better: Independent Suspension or Non-independent Suspension?

Here are the specific differences between independent suspension and non-independent suspension: 1. Structure: In an independent suspension system, each wheel is individually connected to the frame or body through an elastic suspension system. In contrast, non-independent suspension connects both wheels via a solid axle, which is then attached to the frame or body through an elastic suspension system. 2. Advantages: Independent suspension offers benefits such as lighter weight, reduced impact on the overall body, improved wheel traction, and greater comfort compared to non-independent suspension. Non-independent suspension, on the other hand, is simpler in design, lighter in weight, takes up less space, and is stronger than independent suspension. 3. Applications: Independent suspension can be further divided into types like MacPherson strut, double wishbone, multi-link, and others. Most modern passenger cars use independent suspension systems, making them more widely used than non-independent suspension. Non-independent suspension typically includes torsion beam, trailing arm, and leaf spring types, and is mainly found in cost-sensitive passenger cars, as well as in trucks and buses.

How Much Fuel Does a Car Use When Idling with AC on for 1 Hour?

When a car is idling with the air conditioning on for one hour, it typically consumes fuel worth approximately 4-5 yuan. Here are the details: Taking the 1.5 Fengxing 330 as an example, the actual fuel consumption is at least 9 liters per 100 kilometers. In urban areas with air conditioning, the consumption varies depending on driving habits, averaging around 10 liters. If driving in the city with the AC on for an hour, the cost would be about 35 yuan. Additional Information: Methods for Maintaining Car Air Conditioning: 1. Comprehensive AC Inspection: When using the air conditioning for the first time in summer, inspect the AC system thoroughly. Check the refrigerant via the reservoir, see if the AC filter is too dirty, and ensure there are no foreign objects in the radiator. 2. Regular AC Cleaning: Some beginners only think about cleaning the AC when its performance deteriorates, which is incorrect. The AC filter should be replaced regularly. In Beijing, spring brings a lot of dust and willow catkins, which can clog the filter, breed bacteria, and cause a musty smell in the AC. It's best to replace the filter once after spring each year. 3. Don’t Turn Off the AC Immediately After Parking: After reaching their destination, most drivers turn off the AC and leave the car immediately. Unlike in autumn and winter, the significant temperature difference between inside and outside the car in hot summer can cause the AC system to become moldy, leading to the growth of mold.
