We have a 2004 TSX, and had 1,500mi on it, when we did a cross-country road trip from CA to NJ. On that particular trip we averaged 33.5mpg. The best figure ever achieved in the TSX was 35mpg, with the A/C's compressor on & off. Temp avg. 78F. Tire Pressure 37psi., and 92 octane. (Premium octanes across the country range from 90-93) Since then, we have seen averages in mixed driving around 25-27mpg, in NJ's free flowing routes. Winter driving averages poorly at 22-24mpg. I read that this is attributable not only to the freezing temps, lower tire psi's, but an additive that gas stations use specifically for winter - I dont know how much of the latter is true. The TSX is now 1 year old and has 22,500 mi on it, and running decently. I diligently do my own oil changes every 3,000 mi, and dont wait for the recommended mileage/times - hey, at 9 bucks an oil change, its a relatively small price to pay. I have a 1991 Integra LS-S that has 142,500 and runs better now, and with more zing than it ever did. Somehow, I feel the Integra has more soul & passion. The TSX's character is the more refined, quieter, and safer (Volvo-esque) version that I give my wife to drive. Regardless, both are great cars.

How accurate is INFO regarding MPG? by storyman

The navigation computer on the TSX is set to reset with every fill-up. I'm wondering how accurate are the numbers provided by the computer. From what the computer says we are getting 32 mpg on the highway with high octane fuel.

Can't speak for the TSX but the trip computer in my wife's Highlander is typically about 1 mpg optimistic. Keep track of the miles driven and gallons used over your next 3 tankfuls and compare to the trip computer readings and let us know.

Highway Mileage -- Auto v 6 sp? by jg88

So far, have not been able to discern which gets better highway mileage, the 6sp or auto? Doesn't the auto run at lower rpm's at highway speeds? If so, wouldn't the auto get better mileage in top gear?
 
As for premium v. regular, my findings suggested to stay with premium. With regular, it appeared the mileage dropped more than the cost difference so it was a losing proposition. Also, the shifting with the automatic was not as smooth, it was much more clunky with regular. Since most modern autos 'retard' the spark plug for an instant to make the shift smooth, I wondered if regular gas somehow messed up the timing for shifting purposes. Am referring to my old RL -- may be getting in the market soon for a new ride and am thinking about getting a TSX for this latest version of my on-going mid-life crisis. Right now I drive a company car and it appears to be going away in October. Bummer, loved the price! (Hate the ride, a stripped Impala but free is free...) Am thinking '04 TSX, certified/used, or going back to an RL vintage '01 or '02.

You won't have that much of a price savings by going with a 2004 TSX versus dealing for a brand new 2005 TSX during the close-out months.
 
I understand that the Auto gets better mileage than the manual. Highway gets 32 vs. 29. How counter-intutitive...but the electronics has done the trick.

Saw an ad in the local paper in Houston for a privately owned TSX auto for 22,500 with less than 20k miles. That seemed to be a pretty fair price. Figure when the 06's come out, the 04's will drop onto the lower 20k range. The Acura website lists certified used cars right on the dealer cost plus range but I would consider those numbers to be highly negotiable.
 
Am leaning toward the auto because of highway mileage for expressway driving and also because of the manu-matic capability. Seems like the best of both worlds. Reading 30+ mpg commments in here for highway driving is pretty impressive.

20,500 miles in one year is A LOT of miles....

Is there ANYONE who is having problems with getting the indicated MPG on their TSX? I have a 2005 TSX (V4) that I bought because of the sticker indicated 23/32 MPG. I barely break 14 for city and 22 highway and maybe get 180 miles to a tank of gas. (On the rare occasion that empty dot comes on-and it rarely does since I keep the tank above 1/4 full always-I get so nervous because I literally have 15 miles to go). My SUV friends all get better mileage (including the Acura MDX!) Acura Dealerships all give the same excuse:"Independent/Government regulated, not actual numbers. They hand out pieces of paper indicating a 10/22% decrease in the "real world" consumption but even those percentages don't come close. I use premium only, I've had the tires checked, the engine checked. Everyone shrugs their shoulders while I get more and more aggravated every time I'm at the pump.! Any thoughts?

I have a 2005 TSX auto W/Navi. I have found MPG swings GREATLY depending on the right foot. When I have my "foot to the firewall" often I get the low 20's sometimes dipping into the upper teens. If I drive like a sane person, gentle acceleration never speeding I get 28-29 MPG. On the rare occasion my wife drives even in the city she gets 30+ in the city! Her numbers don't count though, her normal car is a 2004 Prius. She drives my car with a very light foot much like the way she drives her car. On long highway trips I get a steady 35 MPG+ going 70-80 MPH.

I find it hard to believe you only get 180 miles per tankful. That's just unbelievable. I can usually get 350 if I drive conservatively in my '04. Are you calculating the mileage manually or by relying on the navigation system?
 
BTW, the TSX four-banger is an I4, not a V4.
 
Also, when the yellow light comes on, you have better than three gallons of fuel left, which will take you closer to 60 miles than 15. The TSX is very conservative in this regard, with the light coming on so soon.
 
Sorry to hear of your problem, but I've never heard of a TSX getting fuel mileage that poor. Perhaps the motor is not fully broken in. Keep driving it, maybe things will improve. Other than that, I just don't know. Maybe you can look into your local lemon laws.
 
Remember, if you feel something is truly wrong, don't let the dealer off the hook. Stay after them.
