How does engine oil selection affect Honda City’s fuel economy?

Using the wrong engine oil viscosity can increase engine resistance, leading to higher fuel consumption. What is the recommended engine oil type for different Honda City models, and can switching to fully synthetic oil improve mileage?

The type of engine oil used in a Honda City has a significant impact on fuel economy. Choosing the wrong oil viscosity increases engine friction, which in turn makes the engine work harder, resulting in more fuel consumption. The recommended oil types vary for different Honda City models, but typically, a 5W-30 o r 10W-30 oil is preferred. Using fully synthetic oil, which has better resistance to heat and friction, can improve mileage. Synthetic oils flow more easily at lower temperatures and maintain their viscosity at higher temperatures, optimizing engine performance and fuel economy. Thus, switching to fully synthetic oil, if not already in use, can provide noticeable benefits in fuel efficiency.
