How can I optimize my vehicle's fuel efficiency?

I have noticed that my car's fuel consumption has been increasing lately and it is becoming a costly expense. What are some ways I can improve its fuel efficiency?

One way to optimize your vehicle's fuel efficiency is by regularly maintaining its engine and ensuring that it is properly tuned. This includes cleaning or replacing air filters, spark plugs, and fuel injectors. A well-maintained engine uses less fuel and provides better performance.

Another way to improve fuel efficiency is by reducing your car's weight. Remove any unnecessary items from your vehicle, such as heavy tools or supplies, and try to travel with less fuel. This will reduce the overall weight of your car and help it use less fuel.
