Does mixing engine oil occasionally have any impact?

Mixing engine oil occasionally does have an impact. Engine oils should not be mixed. The methods to determine when engine oil needs to be changed and the precautions for use are as follows: Methods to determine when engine oil needs to be changed: The simplest way to check the shelf life of engine oil is to observe whether the viscosity of the oil has changed, determine if the smell of the oil has faded, and observe whether the color of the oil has changed. When observing changes in oil color, pay attention to changes in the additives within the oil. Additionally, filter paper or electronic instruments can be used to check whether the shelf life of the engine oil has expired. Precautions for using engine oil: The selection of engine oil should be based on the requirements of the engine. Choose an oil that matches the engine. Oils of different brands should not be mixed. Multi-grade oils should be selected as they offer advantages such as savings, long life, and high efficiency, providing better protection for the engine.

What size tires fit an 18-inch wheel?

18-inch wheels have a rim width of 7.5 inches and are suitable for 225mm wide tires, with a maximum width of 235mm. There are many ways to represent tire specifications, with four common types in the market: British, German, metric, and American standards. The German standard is similar to the metric system, except that the tire width is expressed in millimeters, and the aspect ratio is added. The inner diameter of the tire is still expressed in inches, followed by the load index and speed rating. Wider wheels and tires are not suitable for civilian vehicles because wider tires create significant rolling resistance, requiring sufficient horsepower to drive normally. Larger wheel sizes result in smaller tire aspect ratios, greatly improving handling and steering precision. The only drawbacks are increased fuel consumption and reduced in-car comfort. It is important to note that the purchased tire specifications should ideally match the original tires installed on the vehicle. If changes to the tire specifications are necessary, it is essential to visit a professional modification shop for a tire upgrade or consult the vehicle manufacturer.
