How Long Can You Drive After the Buick Displays Fault Code 82?

Buick fault code 82 indicates that the engine oil life is too low, prompting the owner to perform maintenance and change the oil as soon as possible. Engine oil has a certain service life, and it is not recommended to drive when the oil life reaches 0. The vehicle's onboard computer defines a cycle for oil life based on mileage, meaning the oil should be changed every 5,000 kilometers. While checking the engine oil, owners can also use oil test filter paper to check if the oil has deteriorated. More information about Buick is as follows: 1. Introduction: Buick is an automobile brand marketed by General Motors in the United States, Canada, and China. It is a major pillar of General Motors, driving progress in the entire automotive industry. Buick holds a significant position in American automotive history. 2. Models: Buick includes many well-known models: Excelle, Yinglang, Verano, Envision, Regal, LaCrosse, Encore, Encore GX, Envision, Enclave, GL6, GL8 Land Business Class, GL8 ES Land Baron, the all-electric Velite-6, and the high-end sub-brand Avenir.

Is it allowed to make a U-turn on double yellow dashed lines?

Double yellow dashed lines allow U-turns when there are no prohibitory U-turn signs and when it does not affect normal traffic flow. However, double solid lines prohibit U-turns, and violating this rule constitutes a traffic offense. According to the Road Traffic Safety Law, violators will be fined 200 yuan and receive 3 penalty points. On long roads, solid or dashed white or yellow lines are usually present in the middle section or before intersections. U-turns are prohibited on any solid lines. Permissible U-turn scenarios: Intersections with U-turn signs allow U-turns: If an intersection has a clear U-turn sign, U-turns are permitted. If there is a U-turn traffic light, follow its instructions. In the absence of a traffic light, U-turns can be made as long as they do not obstruct other vehicles or pedestrians. Intersections without explicit "No U-turn" or "No Left Turn" signs allow U-turns: If there are no signs explicitly prohibiting U-turns, they are allowed. "No explicit prohibition" means the absence of "No U-turn" or "No Left Turn" signs and no solid center lines, in which case U-turns are permitted. Yellow grid lines also permit U-turns: Yellow grid lines are no-parking zones marked at intersections prone to congestion due to temporary stops, important facility entrances, or other designated areas. Stopping on these lines (including waiting for traffic lights) is illegal. However, U-turns are allowed on yellow grid lines as long as there is no central barrier, effectively making them "U-turn permitted" zones. Intersections with U-turn traffic lights: If a U-turn traffic light is present, follow its signal—U-turns are allowed only on green. When "No Left Turn" and "U-turn Permitted" signs coexist: U-turns are allowed, but left turns are prohibited. Note that "No U-turn" does not necessarily mean "No Left Turn." Precautions when making U-turns at intersections: Check road markings—U-turns are strictly prohibited on solid lines under any circumstances. Continue driving to find a suitable U-turn spot. If a "No Left Turn" sign is present, U-turns are also prohibited at that intersection, even if "No U-turn" is not explicitly stated, because U-turns inherently involve a left turn. U-turns must be made from the innermost left-turn lane. U-turns are not allowed from the second left-turn lane. Yield to straight-moving traffic before making a U-turn. Failing to do so will make you fully liable for any accidents. Near intersection stop lines, lanes often have guiding arrows. The leftmost lane may not always have a left-turn arrow—if it shows a straight arrow, U-turns are prohibited even without explicit "No U-turn" signs. U-turns on crosswalks are illegal and constitute a traffic violation.

What is the appropriate tire pressure for driving on highways?

Generally, the tire pressure of a car should be maintained at around 220-260Kpa. Before driving on highways, it is advisable to inflate the tires to around 250 or 260Kpa. Excessive tire pressure: The friction and adhesion of the tires will decrease, affecting braking performance, causing steering wheel vibration and deviation, reducing ride comfort, accelerating wear on the central tread pattern, and increasing the risk of tire bulging and stone trapping. It also causes excessive stretching of the tire cords, reducing tire elasticity, increasing the impact during driving, and amplifying road noise. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, leading to internal cracks and blowouts. Insufficient tire pressure: The friction coefficient with the road surface increases, leading to higher fuel consumption. The friction between the tire and the ground multiplies, causing a rapid rise in tire temperature, softening the tire, and drastically reducing its strength. High-speed driving under low tire pressure can result in blowouts. Low tire pressure increases tire deformation, leading to sidewall cracks and excessive flexing, which generates heat, accelerates rubber aging, fatigues the cord layers, and may cause cord breakage. It also increases the tire's contact area with the ground, accelerating wear on the tire shoulders.
