I'm gonna save you all some trouble

THE BIGGEST THING YOU CAN DO TO GET BETTER GAS MILAGE IS TO DRIVE LESS AGRESSIVELY.

with the TL there is absolutely NO reason go go above 2.5K on the tach in city driving...even getting on the freeway I rarely go above 4.5K

Other things that will help

proper tire pressure
clean air filter
use the right oil for conditions and change it as recommended (definately put a new filter on)
don't wait til the last second to get off the gas and brake.....coasting and anything above 1500rpm = fuel cut (ie not pulsing the injectors)

Mythbusters already disproved the car being sooth = better gas milage (search on golfball car to see what I mean)

negative ghostrider, modern cars such as the TL are designed with airflow even if all the windows are up and all the doors are closed and properly sealed

i am at about 22-23 MPG in my car... i do a mix or city/highway daily--- i installed a K&N air filter to try and help with more MPG. friend has one in her TL & said it helped add about 3-6 more MPG! we shall see. that thing was $60...

the only issue with this is the chance for rocks to fly up and cause damage.

id rather get less gas mileage and have a flawless car then save a few bucks on gas but have nicks in the paint from rocks.

Been awhile since anyone posted here. I decided to look at my stats on my car today and here is what I saw. This is a mix of driving and trust me I love flooring it every now and again.

ZOMGVTEK

Acura604

I drive 60% hwy and 40% city per week.

Amazing to get 560km (apprx 348 miles )out of a single tank! Filled up at this point and had 2 gallons left.

I don't drive aggressively but every now and then when the hwy opens up...I let loose.

08 6MT-S gets better mileage than my 08 5AT TL

So here's a question, let's say you're sitting outside in your car waiting for someone for around 8 mins. Does it save more gas to turn off the car and then turn it back on when they get in the car, or to just sit with the car on in park?

ZOMGVTEK

Anything past about 2-5 seconds of idle will save more gas to kill the engine.

94eg!

Here are my vehicles:

Then what is the reason to drive TL? There is also no reason to own a car with V6 or car at all.

If main goal is to save gas then buy a car that is just for that.

LaCostaRacer

You definitely want to cut the motor for 8 minutes of idle time. I did an experiment a couple of years and tried cutting the motor at traffic lights where the wait might be 1-3 minutes and I increased my MID's and actual MPG by 1.5 MPG- same commute and driving habits otherwise. The arguments for not doing this regularly are: excess starter and engine wear, extra stress with trying to start engine in time (particularly when first car in queue at light).

If you go that route at lights leave the car in neutral if you have an auto- much easier to get going again quickly and car starts in neutral too.

Thats an auto Paper? You got me beat at that speed, but this was the return trip after I picked the car up. Not quite optimal MPG driving, just obeying speed limits.

LaCostaRacer

^ But 168 miles and getting 34MPG is more impressive than 29 miles for 36MPG. Even a short downhill grade will skew a 29 mile run. The best I have done is 34 MPG for 44 miles and an average MPH of 66. I have had lots of 32MPG runs at 400+ miles.

it's not 36mpg, it's 38. However I know people would doubt me as soon as I posted it up, but I guarantee you it's not a downhill road. It was the 60 west freeway from riverside to LA, ask anyone from around here, it's not downhill, it even has an occasional slight up/down. anyways, it was only 29 miles because I made that 1 trip, I would have driven longer but I was already at my destination.

Acura-OC

Officially LA is 98 feet above the sea level and Riverside is 1,536

94eg!

It's still a useless comparison. So what if you get 38mpg for 29 miles. Try tracking your mpgs on Fulley.com for a few months and then tell us what you REALLY average.

YeuEmMaiMai

so you want to drive like an asshat in the city? 2.5K gives you enough grunt to move along nicely...

driving a CL is nice quiet comfortable and relaxing and so is the TL

my main goal is to save wear and tear on my car that i paid good money for and driving conservatively does just that........along with getting me great fuel economy for that car....

Acura-OC

Letting my TL shift between 3.5-4K makes me an asshat? I drive this car the way it was designed to drive, what to save on gas use bicycle.

perilousp

When I got my car I obviously wanted to know its limits, so for the first two tanks I got about 17-19 mpg (all city), but now that I've had my fun I've been trying to see how efficient I can get it. Got anywhere from 33 mpg to 26 mpg driving like a granny, so I'll see what my average ends up being on this tank.

Honestly I do like the whole part where I can drive it to get even into the area of 30 mpg in city, but if need be I can quickly get up to speed/pass someone. My

YeuEmMaiMai

Oobvviously someone dosen't quite understand......lol the TL is not designed to be driven hard all the time. It was designed to be a competent sporty sedan......that is reliable when one takes care of it.

and yes constantly running the car up to those rpms in the city where traffic is congested = asshat...

"derp derp well the car was meant for that derp derp" enjoy the hefty repair bills

It seems that every time I post on here my mileage gets worse

I was getting 26mpg on 91 a while ago, it went down so I went to 94 and it made no difference still at 23mpg. Just before this I was getting 29mpg on 93 while I was down in the states where its warmer.

ez12a

gas is getting a bit cheaper now with the winter blend and all. I'll try to start filling up completely and logging. Been only putting 10-20 each time. I suspect i'll get mid 20s.

piggydog

this car is great on the freeway in 6th gear. I made it from socal to vegas with a third of a tank left. So 400 all freeway miles is definitely doable. City driving is another story.

94eg!

I get 400 miles on every tank just driving to work & back here in Vegas (50/50 freeway & city). Granted our traffic light network is quite advanced though.

1995hoo

There's no question that it's doable and that if you do a full tank out on the open highway (no traffic jams or roadwork delays), you ought to top 400 miles unless you find yourself in the mountains where you might be using lower gears a lot. My record is 455 miles on a tank. I haven't beaten that because usually if I stop for lunch I'll just fill up the tank then, regardless of mileage, to avoid the nuisance of having to make another stop later (or, if I will be passing through New Jersey when I might need to fill up, I make a point of filling up before I reach Jersey because of their stupid "no self-serve gas" law).

wise_optimist

I drive about 85 miles a day, 75 miles of highway, 10 miles of city driving.

I get about 29.5 mpg, calculated manually. It is slightly better when it's warm.

1995hoo

I believe I took this picture in Emporia, Virginia, in July 2011. We were on our way back from Florida. The low numbers for distance and time are because I reset the trip computer each time I fill the tank (after noting down the price per gallon, trip meter, odometer, number of gallons/litres, and the mpg and mph numbers).

-mileage you are getting: 25 city/ 30 hwy
-auto or manual: manual
-year car: 2005
-grade of gas: 93 octane
-where you live: Las Vegas, NV
-regular temps: 60
-highway or city driving ratio: 90 % highway / 10% town/city
Tips:
-open windows/moonroof instead of A/C when possible: Living in the upper Minnesota, open widow is the best AC in Spring and Fall choices
-use cruise control when you can: Too much traffic where i live, over 400,000 people using these highway. Saint Payl/Minneapolis.
-take off from a stop slowly: Shift below 3K RPM
-switch from 1st to 3d etc when possible: Never.
-get into 5th or 6th gear asap: If I do city driving, I stay in 3rd gear since speed is 30mph. Highway, you just have to go traffic speed.
-for manuals put into neutral and cruise up to stop signs and lights or if you see traffic ahead: ? im confused

Can anyone think of anything else? Use some free flowing mods to free up some air in the engine such as jpipe, exhaust to get better MPG.

94eg!

This statement is the complete opposite of what you should do. If you keep the car in gear while coasting, the injectors are completely shut off thereby reducing consumption. Also I believe it's possible for drive-by-wire throttle systems to reduce pumping loss during off-throttle deceleration by leaving the throttle plate cracked open while the injectors are switched off (less engine braking effect). Though I have no idea if Hondas are actually programmed to do this or not.

mau108

How so? I can't fathom how a combustion motor still running without fuel.

ZOMGVTEK

In AT's the torque converter locks up and frivolously spins the engine without running the injectors. In M/T's obviously the driveline is locked already, but the injectors are killed under some circumstances.

At least in my M/T TL, fuel cut won't start unless the engine speed is above something like 1,300-1,400 RPM. It's a bit picky until you pass about 1,500. Changing gears and never touching the gas after changing results in less aggressive fuel cut, until you touch the gas again and let off or are at sufficiently high RPM.

It's typically really easy to tell when its cutting fuel. I have no experience with this 'grade logic' system, but I would imagine it decelerates the car by cutting fuel and braking by using the engine to pump air. Most every modern vehicle has some sort of fuel cut system, some are just less aggressive and less noticeable. If you snap off the throttle above 45-50MPH, you should be able to distinctly feel the engine output reduce, and then the driveline unload as the injectors are cut and the torque on the transmission reverses. Don't touch the throttle until the engine slows down to about 1krpm and you will feel the fuel cut stop. The slop in the driveline as the torque reverses again will give you some feedback as to when this happens. You might notice a slight fluctuation in the tachometer reading when this occurs.

I didn't read most of the thread, but everything the OP said is wrong.

94eg!

The forward motion of the vehicle back-drive the motor via the wheels when it's in gear. That in turn powers the alternator and keeps all electrical systems functioning.

Same way you can bump-start a manual car by pushing it down a hill and then releasing the clutch in gear once it's rolling fast enough.

i got 29mpg mixed driving. I have 2004 6spd TL on conventional 5w20 oil.
