What Does Deviation Mean?

Deviation refers to when things or actions do not proceed according to the predetermined idea or trajectory. Vehicle Deviation: Vehicle deviation occurs when a car, while driving straight on a flat road, spontaneously veers to one side, causing the alignment between the front and rear axles to become inconsistent with the centerline of the driving path. Hazards of Deviation: Minor deviations can lead to tire wear and tire failure, while severe cases can result in dangerous situations such as tire blowouts and loss of vehicle control. How to Handle Deviation: If you encounter deviation during a long journey, do not panic or slam on the brakes. Instead, firmly grip the steering wheel with both hands, try to control the vehicle as much as possible, and gently apply the brakes intermittently—avoid locking the brakes. If the rear wheels are deviating, it is best to use intermittent braking (pump the brakes) to shift the car's center of gravity forward and prevent the tires from locking up. If the front wheels are deviating, the driver should try to pull the car to the side of the road and reduce speed. After stopping by the roadside, be sure to turn on hazard lights or set up a warning triangle.

What do the 92, 95, and 98 services mean?

92 service refers to 92-octane gasoline, 95 service refers to 95-octane gasoline, and 98 service refers to 98-octane gasoline. 92 service: 92 service refers to 92-octane gasoline, which has an octane rating of 92 and contains 8% heptane. It is suitable for mid-range vehicles (those with relatively low compression ratios). 95 service: 95 service refers to 95-octane gasoline, which consists of 95% octane and 5% heptane. High-compression engines should use high-octane gasoline. Using low-octane gasoline in a high-compression engine can cause abnormal combustion, leading to knocking, increased fuel consumption, and reduced driving power. Of course, high-compression engines can also use lower-octane gasoline, but it is not advisable to choose gasoline solely based on compression ratio. Instead, follow the manufacturer's recommendations for fueling. 98 service: 98 service refers to 98-octane gasoline, which has an octane rating equivalent to a mixture of 98% isooctane and 2% heptane. The advantages of 98-octane gasoline are "two highs and two lows": higher anti-knock performance and power output, and lower harmful substances in the gasoline and lower exhaust emissions.

What grade of engine oil should be used for Toyota Yaris L?

Toyota Yaris L's dedicated engine oil recommended by the manufacturer is 5W30 semi-synthetic oil. In practice, 0W20, 5W20, 5W30, and 10W30 can all be used, but the most suitable engine oil for Toyota Yaris L is 5W30 semi-synthetic. Here is the relevant introduction: 1. The meaning of engine oil grade: The engine oil grade usually indicates viscosity and quality. The viscosity of lubricating oil is often identified using SAE grades. W stands for winter, and the smaller the number before it, the better the low-temperature fluidity of the oil, indicating a lower usable ambient temperature and better protection for the engine during cold starts. The number after W is an indicator of the oil's high-temperature resistance; the larger the number, the better the oil's protective performance at high temperatures. 2. Engine oil classification: It is represented by a combination of two letters. The S-series represents oil for gasoline engines, with general specifications ranging from SA to SN (in alphabetical order, but without SI). Each subsequent letter indicates better performance than the previous one, with more additives to protect the engine. The further back the letter, the higher the quality grade. Among international brands, most engine oil grades are SF or higher.
