Please post your actual TSX MPG. "Real World" Fuel Economy vs. EPA Estimates |

Replying to: KarenS (Jun 02, 2005 9:21 am)  , but whatever the reason, this is a good subject. Like I said in that post, I got 497 miles on one tank when I drove to Virginia and back. I usually get on average, using premium gas, around 420-430 when the weather is warm. In the winter this year, I was only getting about 300-320, which was disappointing to me, but given the freezing cold we had here in PA this season, I guess it's alright. I had assumed that this mileage was about 30-32 MPG, but I had just computed the MPG now and its not really even close to it. I believe the HWY mileage posted on the window was like 32 MPG. The tank is 17.1 gallons, and even on that almost 500 mile tank of gas, the MPG was only 29.24. My average was only 25.15 MPG. That's not even close to what the EPA says. Reading that article and how they figured the MPG, it's pretty disappointing that my car gets so little compared to what it SHOULD get.

I am going to cheat and post a message that I placed in the 'problems and solutions' forum: xxxxxxxxxxx Here is an interesting article regarding the use of Premium Gasoline. http://www.usatoday.com/money/autos/2003-07-30-premiumgas_x.htm Essentially...it is USA Today which quotes a senior Chevron Exec to saying: "I personally use regular even though my owner's manual says you'll get better performance with premium," says Lewis Gibbs, consulting engineer and 45-year veteran at Chevron oil company. He's chairman of Technical Committee 7 on Fuels, part of the Society of Automotive Engineers (SAE) Fuels & Lubricants Council. Gibbs knows gas. xxxxx Basic response so far is that MPG improvement is seen with premium. Somewhat interested to know more as I only had my TSX for one week so far. So I'll keep an eye on the messages on this site. Sorry if I offend anyone by double posting the above message.

I like the new topic, so I'm interested to see what other people post. Take into account, these are MPG from Minnesota, so the winter certainly makes a difference. My TSX is a '04, 6MT. I only use premium (92 plus) gas. In the winter with a ski rack on, I got about 23 or 24 MPG at about 50% city and 50% hwy. All highway at 65 mph with loaded car and skis on the top, I got just over 29 MPG on one trip. Pretty good. In the winter without a rack, I got about 25 MPG at 50/50. In the spring/summer with a bike rack, I get about 26-27 MPG 50/50. On a long all hwy trip, I got just over 28 MPG. But then again, that was with a rack on the top (no bikes). In the spring/summer without a bike rack, I get about 27-28 MPG 50/50. On a long trip I got about 31 MPG once. I think the wind may have been at my back though. I am usually pretty good about not hammering the gas most of the time, which makes a big difference. If I drive hard a lot, I can lose 2 MPG in 50/50 driving easy. Sometimes more. I have also noticed that if you don't accelerate hard when the engine is cold, you get better gas mileage....but that could be in my head. Overall, I am pretty impressed with the performance/gas mileage mix. I am a very happy owner. Just one comment about the guy quoting miles for a full tank of fuel. I don't know if this still applies to newer cars, but I have always been told to keep your gas tank at least 1/4 full. It helps to extend the life of your fuel pump by keeping it from overheating. Plus, you won't ever be the guy on the side of the road walking to the nearest gas station  Anyone else have a comment about this?

Replying to: delmar1 (Jun 02, 2005 12:42 pm) Pretty simple to see if this makes sense. If premium costs 10% more and it doesn't increase your mileage by 10%, then your wasting your money (unless you can tell the performance difference.)

Replying to: lmacmil (Jun 02, 2005 2:39 pm) So if the break-even is a 10% cost improvement with premium...is there a 2.5 to 3 MPG improvement that is consistently achieved??? Especially with same driving conditions and style.

Replying to: rko2 (Jun 02, 2005 1:08 pm) My dad's a mechanic, works on Honda's. He's up on all the new technology and stuff in the newer cars. I was talking to him once about letting the tank run completely dry to see how many miles you can really get out of a full tank. He said that wasn't a bright idea because, especially on newer cars, the fuel injection system relies on the fuel to keep the injectors cool. If there's no fuel through the lines, but your foots on the pedal to go, the injectors could burn out and maybe even start a fire (unusual though). I asked him if that's the case with running the tank close to empty each time, because honestly, that's what I do. He said, as long as there's fuel in the lines everything should be fine. I got REALLY good with estimating how much gas I have in my tank from my old Civic. The gauge was a little whacky and no one was ever sure how much gas was in it. After driving that thing for 4 years, I got great at knowing it. With the TSX, it took about 2 months to get used to the tank. I know that when the fuel light comes on, that I have about 50-70 miles left (roughly 2 gallons). I never once ran out of fuel in either car. Thanks for the concern about me running out of gas though. I appreciate it.

Replying to: delmar1 (Jun 02, 2005 3:19 pm) My biggest question is why some people are so hung up on a savings of roughly $2 a tank using regular, when there are downsides for doing this. You spent over $25,000 on a car that you bought because it is all around great, but I presume also because it is quick and fun to drive. You also probably spend over $800 a year to insure it (most likely much more). So you have invested a lot of money in this great car, and some people are trying to save a few extra dollars a month to live with poorer performance. Plus, I would hate for something to go wrong with the engine under warranty and the dealer give me a hard time covering it because I was using regular fuel. Not saying that it would happen, but there are crazier stories out there. It just doesn't macke sense to me. Does anyone have another explanation? I may just be missing something here.
