To improve fuel efficiency, it’s suggested drivers should maintain which of the following?

Maintaining tire pressure, oil level, and engine temperature is crucial for optimizing fuel efficiency in vehicles. When tire pressure is appropriate, it reduces rolling resistance, allowing the vehicle to move more easily and consume less fuel. Under-inflated tires can lead to increased fuel consumption and wear over time.

Keeping the oil level within recommended limits ensures the engine operates smoothly; insufficient oil can lead to friction and decreased efficiency, resulting in more fuel being burned. Proper oil viscosity also aids in engine performance, which can contribute to better gas mileage.

Engine temperature plays a significant role in fuel efficiency as well. An engine that runs too cold may not combust fuel effectively, leading to wasted fuel. Conversely, an engine running at optimal operating temperature ensures that fuel is burned efficiently, reducing overall consumption.

Thus, all these factors—tire pressure, oil level, and engine temperature—contribute collectively to improving fuel efficiency. By maintaining each of these components, drivers can achieve better gas mileage and drive more economically.
