Total combined mileage to date (4 months) 8,000 miles
30.0 mpg
 
Total mpg highway 32 Total mpg city 26
 
Have used all three grades of gas with premium getting the best mileage by about 5%. What little you save getting another grade of gas (87 or 89) tends to be eaten up in less mpg using the lower grades.

I took a weekend trip during Labor Day from Albuquerque to Bison Ranch in Northern Arizona. On the way back from Arizona, I average 42.5 mpg at 60 mph for 40 miles until I reached the interstate. I watched my mpgs decline on the interstate for 240 miles to an average of 35.3 mpg with the cruise set to 80 mph (used 91 octane, elevation between 5000-7700 feet, outside temp between 75-90 degrees, no wind, 3 passengers and lots of junk in the trunk, recent oil change of Mobil 1 5w-30 and cleaned my K/N filter before trip).

Is frequent shifting the automatic in/out of neutral bad? by obladida1

First off: You guys are my heros! I WISH I could get that kinda mileage out of my '07 auto/nav. I live in the L.A. Valley and I commute to the beach, so I have a big twisty hill to get over twice a day. My average for almost 4K miles is 26.9.
 
When I am going downhill, I sometimes drop the tranny to neutral and coast much of the way. Is it bad for the automatic transmission to be popped in/out of neutral and/or left in neutral for extended periods?

Why in the world would you want to shift to neutral and coast?

I'm not sure I'd be willing to risk damaging an automatic tranny by coasting in neutral like that, but I do it all the time with the 5MT in my '02 Elantra. It's one of the fuel saving techniques I've used to average 33.2mpg over the last 99,000 miles versus the car's 21/30 revised EPA numbers. If you've got a long downhill stretch where you don't need to use engine braking to retard your speed, you can save a lot of gas. Before they put in a couple of traffic lights, I used to coast over six miles on my daily commute from the top of the Palmer Divide clear down past the infamous Ted Haggard's New Life Church (Ted being infamous - not necessarily the church) on highway 83 here in Colorado. Traffic was always very light at 5am and I never went more than 10mph over or under the limit.
 
You might want to check your local laws, though. I don't know about California, but it's technically illegal to coast in neutral here.
 
Thanks to all for the great info on TSX mileage. I've about settled on one as my next ride. I get the feeling that it'll be a lot harder restraining my right foot in an Acura than a Hyundai, though!

i wish that were true but my husband tends to speed more in our 05 hyundai elantra GT 5 speed than he does in our 06 acura tsx 6 speed. we also get good gas mileage in our elantra-average 33.5 mpg. it has just over 60,000 miles-
