Hi PW's
I've been using an automatic Coure 2005 for the past year. When I got it it had a good mileage. But recently I've measured the mileage which is about 10 to 9 km/liters.
I've had it tuned recently, tires are in good condition, water in exhaust, AC works well, and has a smooth ride.
But the mileage has decreased.
Any suggestions as to what might be causing it and how I can fix it?
