If anyone out there owns a 2006 Hyundai, Tucson 2.7, 6 cyl, AT, front wheel drive, let me know how your gas milage is. I have 10,500 miles on mine and get about 19.5 city, and 20.5 hwy. Hyundai is giving me a line that it isn't broke in till 15,000 miles, then milage should improve. After the laughing is done I'd like some comments on this. Thanks

Your mileage is probably as good as it is going to get. Hyundai is hoping you'll stop bothering them so they are blowing smoke.

Using synthetic engine oil and transmission fluid will likely increase your mpg 8 to 10%.
