Why is the fuel economy on my Volkswagen Touareg not as good as it used to be?

I have noticed that the fuel economy on my Volkswagen Touareg has decreased significantly in the past few months. Is there anything I can do to improve it?

One of the main reasons for a decrease in fuel economy is driving habits. Are you accelerating and braking aggressively? Try to drive more smoothly and you may see an improvement.

Another factor to consider is tire pressure. Make sure your tires are properly inflated as under-inflated tires can decrease your fuel efficiency.

Have you had a recent oil change? Dirty oil can also affect your fuel economy. Make sure to follow your car's recommended oil change schedule.

Finally, if none of these steps improve your fuel economy, it may be time for a tune-up. Bring your car to a trusted mechanic and have them check for any potential issues.
