Dear experts need help to save petrol on my car. Currently one tank of 40litre I can only travel 300km. Try a lot of method to lean out the fuel but there is no improvement.

Anyone can help?

Make sure you o2 sensor is in good working condition. Make sure your fuel tables are tuned so that your short term fuel trims are close to 0%. There is no silver bullet.

It also depends on your driving habits.
