The Changan CX70T originally uses SL-grade 5W-30 engine oil. Any oil that meets this specification can be used, and there is not much difference between brands. Engine oil is a crucial factor affecting engine performance and lifespan. The vehicle comes pre-filled with high-quality multi-grade viscosity oil, which can be used year-round except in extremely cold climates. The principle for purchasing engine oil is "there is no best, only the most suitable oil." It is recommended to first use the specifications recommended by the vehicle manufacturer. When selecting oil, always choose the corresponding specifications. If price is a concern and you drive frequently with frequent oil changes, mineral oil or semi-synthetic oil is acceptable. However, if you drive very little and change oil only once a year, it is advisable to use a higher-quality fully synthetic oil. Regarding viscosity grades, some European and Japanese manufacturers, for environmental and fuel-saving reasons, may recommend low-viscosity oils like 5W-20. Simply follow the manufacturer's recommendations. Of course, if the manufacturer does not specify, you can choose oil based on your driving environment. Generally, commonly available oils like 0W-40, 5W-30, and 5W-40 have strong applicability, suitable for most climates in China and most vehicle usage scenarios.

What is the difference between Audi RS series and S series?

Here are the specific differences between the Audi RS series and S series: 1. Product positioning: In terms of positioning, the S series is positioned just below the RS/R series. This series shares production lines with the A-series mass-produced vehicles, from the A3 to the A8, and all Q3/Q5/Q7 models have their own S versions. The RS series models, as the highest-performance products in the Audi family, feature many handcrafted components, with limited production capacity, hence they are produced in limited quantities. 2. Production location: Except for the S6, all other S series models are produced at the Ingolstadt factory. They come standard with Audi's Quattro all-wheel-drive system and are equipped with only one high-performance engine. Additionally, they can be upgraded with more powerful braking systems and stiffer suspension systems to enhance sports performance. The RS series high-performance models are exclusively produced in Neckarsulm. Quattro GmbH also offers customers other sporty high-performance cars from the RS series, with a complete range of models. Furthermore, Quattro GmbH provides an extremely rich array of personalized customization services, producing high-quality custom components for the Audi brand.

What Causes Uneven Tire Wear on the Front Wheels of a Heavy Truck?

When the front wheels of a heavy truck wear unevenly on the inner or outer sides simultaneously, it is often due to incorrect front wheel toe-in. Below is some information on what to do when encountering heavy trucks while driving: 1. Avoid the truck's blind spots: Trucks have large blind spots, especially on the right side. During normal driving, it's common to see trucks driving along the centerline of the road. If slow vehicles block the fast lane, drivers may attempt to overtake from the truck's right side, which can easily lead to traffic accidents. 2. Dangers of trucks turning: When a truck turns, there is a specific term called 'off-tracking,' which refers to the difference in the path between the front and rear wheels on the turning side. If a car remains in this area, the truck driver may not see it at all. It is crucial to stay away from this zone.

What does it mean for a large truck to stop and then start again when turning right?

The meaning of a large truck stopping and then starting again when turning right is that the truck needs to come to a complete stop before proceeding when making a right turn. Due to the large blind spot on the right side of large trucks, which can easily lead to accidents, regulations require that the truck must stop for 5 seconds before starting to move again. Below is some information about encountering large trucks while driving: 1. Avoiding truck blind spots: Trucks have large blind spots, especially on the right side. During daily driving, it's common to see trucks driving in the middle of the road. Sometimes, slow vehicles in the fast lane may force drivers to overtake from the right side of the truck, which is extremely prone to accidents. 2. The dangers of large trucks turning: When a large truck turns, there is a specific term called 'inner wheel difference,' which refers to the difference between the front and rear wheels on the turning side. If a car driver stays in this area, the truck driver may not see anything there at all. It is crucial to stay away from this zone.
