NICE!

I can do 30+ on highway trips but not as high as 35. Average speed between 70-80.

 

ya so much for the "Smart" car. you know , that little thing that gets 30 MPG haha i think it should be called "Notso Smart" car.

 

I guess that's a regular TL, not a type-s right ? I was surprised to find my type-s can ave. about 27-29 MPG on highway .. very happy with this cruiser ...

 

correct. not type-s But hey we all got 6 cylinders.. so aint like its a big diff. Of course I am used to Camaro's and such.. So to me a 6 banger is a 6 banger just almost..

 

I'm sure mine was going higher had my wife not ask us stop midway to go to the grocery store.

 

very cool.. by the way, does anyone know if those newer clusters are plug and play in an 05?

 

if you like to fool yourself,,,drive an hour, and dont reset the meter until already on the freeway at speed~
Thats where a lot of gas goes- getting it up to freeway speed, then it cruises easily

For accurate mileage numbers you need to do nearly full tank run, refilled to same level and calculate miles travelled and fuel burned

 

For iPhone users, there is a free application called Gasbag, which allows you to enter your information and keeps a running tally of your mileage. It also shows you how much on average you have paid for your gas, as well as your cost per miles driven. It uses GPS, I have used it for a couple of months and know that according to my data, I am getting 24.8 miles per gallon over the last ~1500 miles, and that I have paid an average of 2.93 (Shell V-power 93 mostly) at a cost of $0.118 dollars per mile. You can look at the totals by week, month, year, or all and email yourself your results as a backup. I am not a developer of the program but do make a point to use it every time I fill up.

 

+1.

The MID is inaccurate. It's always 1-2 mpg off. This is the correct way to do it.

 

ive even seafoamed my car (5AT) and struggle to get just 25mph on all highway, doing 70-80 ...what gives?

 

That's why I love the TL. On other forums (IS, Maxima, G) they often have topics complaining about how bad their mpg is while we have topics bragging about it.

 

I had 40 mpg one day a few moments

 

Seafoam and the AEM V2 changed my life as far as MPG!! I highly recommend both.

Use your Cruise Control, keep your windows (mostly) rolled up and turn off the A/C. I took my first road trip last weekend--150 miles each way, plus tooling around the whole weekend. Averaged 29MPG for the whole trip and did it all on one tank of gas.

 

I've always been from that school of thought up until recently.

The TL's computer knows injector pulsewidth and fuel pressure so it knows exactly how much fuel is used down to the ounce. It obviously knows the mileage so the calculation should be extremely accurate.

Filling up at the pump, there are still variables such as pump cutoff point. I have no idea how consistant or inconsistant they are as I have no way to find out. Even if you get only an extra 1/4 gallon one time vs another, that's your 1-2mpg right there. Now average it out over 10+ fillups and it's probably very accurate.

BTW, it was nice meeting you yesterday.

 

I forgot, you can manipulate the MID easily. I have a picture somewhere of it saying >50 for over 30minutes and something like 48mpg for an hour. That was me getting up to speed and resetting it right before I hit the downhill portion of the grapevine heading to Bakersfield which continues slightly downhill for 45 miles.

I've used the MID to tell me when I'm on a slight incline or decline. On my old commute to work I consistanly averaged 26mpg going to work and 35-37 on the way home but I couldn't tell I was on an incline.

 

Which GasBag are you talking about? Neither get very good ratings so I'm curious. I have been using Gas Cubby which provides most of the same info but requires a little moe manual input.

Just saw that Gas Cubby is now $9.99! I got it for no more than $2.99 a few month ago. They may run periodic sales, it's a good app.

 

I get 32 when driving 70, 35 at 65 and 37 at 60mph. Too bad when I drive in city or commute to work I get like 13 MPG...Anyone know why? Tires PSI = 38, Oil Change with 5W-30 Synthetic Mobil 1, seafoamed, and I don't accelerate hard (less than 3k RPM 99% of the time).

 

excuse my noobness, but I didn't know the AEM V2 (that type of part in general ratherl) had fuel gains as well? I thought that was strictly for performance and that nice sexy sound lol

 

You will get mixed responses. Mine is; high performance engine most efficient at a steady 55-65 MPH. Stop & Go traffic kills the gas mileage on this car dead. In addition the extreme heat that we both experience does not help. Keep a eye on your miles per hour as well as mpg. They rise and fall together. My overall average for the year is 18.1 mpg. I have seen a low of 14.2 and a high near 30.0 mpg. It's the nature of my traffic and driving style. I have almost 55,000 miles on the car.

 

The MID is very accurate unless you have changed tire size. Other then that, it is spot on, I have checked mine manually and it matched up.

As for the 35, that is good, but try 34MPG for an entire tank! Had you gone 55 mph, it would have been even better. As you can tell from the photo, I only averaged 38mph, so it was not all highway. This was an experiment last year. I wanted to see how high I could get the MPG using some of the techniques the hyper milers use.

 

I've been tracking every tank i do and MID isn't a 100% on. I fill up at the same gas station using the same pump. When filling up and the pump clicks off i wait a couple seconds and pull it again till it clicks off again. So i like to think that i am being consistent in how full i am getting the tank.

One weekend the MID showed 30, but filled up and it was 28.6. I am jealous of you 30+ guys, but upper 20's is still great.

 

Black_05_TL_6SP thats pretty impressive man! I could never do that my foot is way too heavy lol

 

No matter how hard you try, unless you fill up the fill neck every time, to guarantee that you are pumping the same amount. Once the pump clicks off, you can still fit between a 1.5-2 gallons worth of fuel. So you can have a margin of error in the calculations.

And thank you AnthraciteAspec, it was very hard to stay out of it.

 

I took some screenshots of the application and my data and if I can figure out how to post them I will. The application is called gasbag. When I told someone at work about it last week they were able to find it using the search function.

 

Here are screenshots as promised. I know it's against the male dna, but I did read the instructions and now know how to post pictures.

 

wow i dont think 35 is doable on a type S ... the highest I have hit was 30 ...

 

You are correct (mostly), the CAI is a performance part. However, I have found that the CAI makes my throttle a lot lighter, which can translate into MPG if you don't ride it like Dale Earnhardt Jr all of the time. So, when using Cruise Control and driving normally, what used to be performance becomes MPG.

At least, this is my take on it. I think this is why the marketing guys claim both horsepower AND mileage increases. In fact, it is performance OR mileage---not both.

Seafoam, on the other hand is absolutely incredible. I had never heard of it before this site and used it on my 06 with 39K both in the tank and through the throttle body. The first full tank after application my MID numbers were crazy high. Once everything settled down, I can say that it gave me an additional 3-5mpg on it's own. I do a lot of highway driving and was looking for MPG numbers more in line with what others here have reported. I am now beginning to see them---in the area of 28-31mpg consistently. Will let you know what happens after the 2nd application after 2000 miles.

I know I Hate Cars has some strong feelings on the subject of CAIs and performance/mileage and would like to hear his opinion on my comments, as he seems very knowledgeable and can translate his opinions into very good discourses.

 

In stock form, give it to a hypermiler and you'll get 50!

Do some weight reduction, get prius tires and a few performance mods and you can rock 35 on the highway...

 

LOL. That last paragraph was too nice. It's more like opinions into shrewd crude discourses.

Seriously though, you know my opinon on the CAI, unless it's preventing part throttle detonation it can't increase mileage. More airflow before the throttlebody can't increase mileage, it's totally impossible. Exhaust mods can do both mileage and performance. Intake can only increase performance.

Think about this, the car always maintains the same AF ratio. The throttlebody is an artificial restriction to airflow. Going from a plugged airfilter to no airfilter would only give you the same effect as cracking the throttle open a little more.

I usually top off my summer gas with a mix of tolulene and I see up to a 3mpg increase in mileage during the hottest months due to it being able to run full timing again.

 

I don't mean to beat a dead horse---just trying to express my experiences as best I can. No matter what, all of you guys on AZ have taken me to a higher plane, as far as loving my Acura is concerned.
Will have to investigate tolulene further. At this point, these 2-3 mpg increases are adding up nicely.

Thanks for your comments.

 

Thanks, that's GasBag Pro and today it's $0.99. Funny, there are two programs, the other one is the free trial version. They are listed as 'GasBag Australia' which is what confused me. The pro version looks like it could give Gas Cubby a run for the money.

Whatever, I still only average 18.1 MPG.

 

I have a few pictures of some good gas mileage with my TL as well. I will say that the exhaust mods and lowering springs aid in achieving better gas mileage, moreso than one might think.

I had performance springs which yielded a 1.5" drop in ride height, I'd be lying if I said it didn't help.

 

what does the AEM V2 do that helps improve mpg?

 

It's a performance intake, it flows much more freely than the stock airbox and thus allows air to enter the throttle body more efficiently. An increase in MPG is seen because there is less restriction and the car produces slightly more power.

 

Beside all the factors listed above, tires make a big difference in MPG, i 'm using sticky summer directional with more than average contact patch area. It kills MPG from 30-31 down to 26-27 in my case. This is going from 33 psi to 38, 39 psi.... i was hoping the added psi can counteract the sticky tire, i guess not...

 

I've gotten 32-35mpg on a straight hi-way run. I'm amazed that the TL will return that type of gas mileage. I only get this on a run where I fill up and hop on the highway, never get off. Like when I take my daughter to college.

 

This is the part where I tend to lose people. It took me a while to understand myself.

The throttle valve is just that, a valve. If you reduce restriction upstream of it and it lets more air in for a given opening, you make more power at that opening reducing gas mileage. Even if you don't have to open it as far for the same power, you're getting the same amount of air into the engine and the corresponding increase in fuel.

In other words the throttle valve has nothing to do with mpg. It's the amount of air the engine sees after the throttle valve that determines power and mileage.

An extreme example would be a turbo car. It may blow 10psi of boost at a halfway closed throttle valve. You're making 50% more power now but you wouldn't expect to get the same mileage at half throttle as you did without the turbo. It's the same thing as the CAI, just much more drastic.

Think of it as more airflow= more power and less mpg, regardless of throttle opening.

There's always the chance that the cooler charge is reducing detonation and it's possible to see a mpg jump from that.

As for tolulene, if your car isn't pinging, there's no need for it. If it does ping like mine does in the summer time, you will pick up some mpg from it because it will allow the computer to run full timing. I doubt I break even price wise, the tolulene is more expensive than the increase in mpg but I use it to save the engine and give me a few extra hp.

Hope this helps.

 

I'm not an iPhone owner, but I use www.fuelly.com to log my MPG performance. It's free and a decent tool.

 

i got 29 on my way back from chicago this weekend in my 6 speed. and i was dogging the car. avg speed was over 90
