FAQ:

1. Does using a fuel-efficient oil really improve gas mileage? Yes, lower-viscosity oils generally reduce friction, leading to better fuel economy, although the improvement may vary depending on your vehicle and driving style.

7. How can I tell if my oil needs changing? Check your dipstick regularly. If the oil is dark, dirty, or smells burnt, it’s time for an oil change.
