How to Improve Your Car's Fuel Efficiency?

I have a BMW car and I'm wondering how can I improve its fuel efficiency? What are some tips and tricks to save money on gas and reduce my carbon footprint while driving?

One way to increase your car's fuel efficiency is to make sure your tires are properly inflated. Underinflated tires can decrease your car's fuel efficiency by up to 3 percent. So, regularly check your tire pressure and refill them if needed.

Another tip is to avoid excessive idling. Idling wastes gas and money. If you're going to be idling for more than 30 seconds, it's better to turn off your engine.

Also, try to drive at a steady speed instead of constantly accelerating and braking. This can improve your fuel efficiency by up to 20 percent on the highway.
