Hey there, I have a 07' TL Type S and am getting about 250 miles per tank. I've googled around and also read a few threads about mpg here on acurazine, and noticed some people get over 350 per tank!

I recently had the cannister purgle valve replaced ( I kept on getting the tighten fuel cap warning) changed filters, spark plugs. haven't done an oil change because the oil was changed, at the dealer, before i bought the car about a thousand miles ago ( the guy i purchased the car from worked at the acura dealer).

is there anything i am missing here? I dont carry much in the car usually and i drive been driving it mostly highway but some city, getting 19 - 20 mpg (city and highway)

any help is much appreciated!

19-20 mpg seems pretty normal to me. Im pretty sure thats how much most people are getting. It's just that some people may occasionally take a long highway trip that gets them 300+ miles to a tank and post on here so it seems that way. Also, how many miles a tank depends on how low you want to push on your reserve. For example, I've once driven 50 miles after the light came on

06TLMatt

19-20 mostly highway sounds very low to me. I consistently get 29-32 on a 40mi. commute, mostly highway , a couple miles of city.

There are TONS of variables. No two people are going to get exactly the same MPG.

Do you accelerate quickly? Do you coast down hills? Do you set the cruise control when on the highway? Do you use premium fuel? The list goes on and on.

TacoBello

Check tire pressure. Low inflated tires will drop your economy.

Check to see if any brake calipers are seized. That could have an effect, although less likely.

truonghthe

your MPG is normal for the car was rated for. My rule of thumb for good MPG is easy on the throttle and try to keep the RPM under 2.5k during shifting

6MTSSR

First off premium fuel ONLY! Winter weather/gas blend and your mpg will suffer.Was getting 19/20 mpg/250-270 on a tank.Now with the blends changing im seeing 22/24 mpg 325/340 on a tank.07 type s a/t.My car is mechanically in tip top shape and I ck tire pressure once a week.Latest tank I got 343 miles, 22 mpg average speed of 24 mph as per the info center.I drive HWAY/CITY just about a 50/50 split.

xiily

Always use premium fuel, though i haven't choosen one place because the car doesnt seem to like gas from anywhere.. Pretty light on the throttle. My tire pressure is to spec (says on the door jamb, 32psi front 35psi rear, should i change that?). I'll try paying more attention to the rpm's, but shouldn't be too much of a factor since i don't always take off. Usually on the freeway i set cruise control to 70mph.

i'd like to add after the spark plugs, filters, and canister valve were replaced, i was getting 29mpg. but that lasted one whole round trip (~65 miles).

this morning 45 dollars filled my tank, and driven 18 miles round trip getting 11 mpg (i usually reset my meter when i fill up). there has to be something.

Don't fully rely on the MID for your MPG figures. Calculate it by hand each time you get gas.

06TLMatt

If you're actually getting 11mpg and driving normal, there's no way that something isn't wrong.

tires/wheels make a difference too. If you have some heavy 20" rims, or super sticky performance tires, those will make the engine work harder to stay at speed

LaCostaRacer

What does the MID say for Average MPH? There is a huge difference with cruising on the highway vs. driving in town. My guess is your mileage is going to reflect how the car is driven and have nothing to do with the parts that were replaced.

LaCostaRacer

With almost 9 years of back tested data, I will confirm that the MID is pretty accurate within its integer limits. My MID might read 20 MPG when the actual is 19.7- that's enough accuracy for me. For 95% of my fillups- the MID is +/- .5 MPG of actual. Needless to say, I have full trust in the MID reading now.

I just entered 4 months worth of data at fueleconomy.gov the other week and have about 325 fillups worth of data now to substantiate these claims.

MarcDavidoff

The MID is pretty accurate from what I've noticed. I typically get anywhere between 24-30mpg

xiily

I'm assuming that my driving is whats affecting the mpg. As another person suggested earlier today, i'm keeping rpms under 2.5 (which i previously was anyway, but i'm keeping an eye on it) raised the tire pressure. today i drove about ~50 miles highway, and my mpg was 22, but there was loads of traffic into the city.

my husband was able to reset the ecm and pcm (computers) with a scanner ( one of those fancy ones, ) and my whole MID reset. I guess by resetting that, the car computers will learn my style of driving.. anywho, The car isn't throwing any codes, o2 sensors were reading and working properly.

I filled up this morning and i'm about to reach half a tank, with less than 100 miles since fueling up. I'm going to stick to driving it like a little old lady for the next week but I don't know how well driving like that will work for..

regardless of this fuel issue, i love my car. Just wish the fuel economy was better.

How many gallons are you putting into your tank at fill-up? If I fill up when my car tells me to, I only end up putting in about 14.5 gallons (and that is usually around 330 miles), but the tank will hold 17 gallons.

My 2008 TL Base usually suggests I get gas a lot earlier than necessary. But most tanks I'm getting about 350 miles, and my MID shows 24-25mpg. It's not always very accurate and if I calculate it myself I'm usually averaging around 23mpg.

xiily

When I fueled up today, it was about three to four notches to the last line.. it was 11 - 12 gallons to full.

Approx. how many miles do you get after the gas light turns on?

UA7X

I usually fill up when the gauge is below the last line, but I'm also familiar with my driving style and average mileage so I'm confident on what my car can do.

All it takes is getting used to your car based on how you usually drive. If you filled up at 11-12 gallons, you know it was early because the tank holds 17 gallons. So if instead you filled up with 16 gallons, you would probably get another 80 miles or so to that tank.

Simple math will tell you what you should get with a full tank. The Type S is rated at 17-26 mpg, so if you figure you average 20 mpg for the sake of easy calculating, 20 x 12 = 240 miles which is about what you're getting. But 20 x 15 gal = 300 miles, 20 x 16 gal = 320

I would shoot for 300 on your next tank and see how many gallons you put in at fillup.

TacoBello

I found the MID is pretty accurate as long as my driving habits don't vary too much. The only time I found the MID to be off was when I drove the car lightly for 3/4 of a tank of gas, and then switched to mashing the go pedal for the last quarter. The average the MID displayed was more conservative than in reality.

UA7X

I've noticed the same. If I am completely consistent with my drive style the MID is very accurate, but if I drive easy/normal for 95% of my tank, but then also have two or three heavily accelerated pulls my MID will be incorrect by up to 2mpg. But it's designed that way on purpose, it calculates what you are normally averaging, not what you actually average (if that makes sense).

So basically 95% of the time I'm getting 25mpg. But 5% of the time I'm only getting 11mpg and it just doesn't adjust much for that. Most people probably don't calculate their own mpg if the car does it and displays it for them, so there's reason to be a little more conservative (keeps the driver happy).

Challenge accepted 😀

To be honest I baby the heck out of my car, I haven't let the gas light turn on since I bought it back in March. I honestly don't even know where the light is 😂.

UA7X

LOL. You and your car need to become better friends. take it out for a nice evening on the town, get to know it better

I originally thought I was getting terrible gas mileage because I was always filling up as soon as the light came on, but then I read the car has a 17 gallon tank. Ever since then I've been pushing the limits, riding on the edge, living at a 1/4 mile at a time.

Am I sounding too "Hollywood"?

06TLMatt

^ Same - I've never had the light come on... I've always been told that fuel pumps are cooled by the fuel and to not run it for long under 1/4 of a tank ..

Oh Sickest TL

iTrader: (3)

same I've never seen that light lol..

but I get like 550-600 kms to a tank on highway which equates to 350-375 miles

Dunnik

The base TL has the same gas economy as the Type-S, I've read, so as a base TL owner I feel I can chime in on this:

The best I've ever gotten is 6 L/100km on a long highway run - 39 MPG!

For shorter highway runs I seem to be getting 7-8 L/100 km (30-33 MPG).

My commute is about 50 km both ways (31 miles), mostly highway, but with some stop and go city traffic at either end. I average about 10 or 11 (21-23 MPG).

Otherwise, I try to keep the usual economy tips in mind; keeping tire pressures up, keeping revs to at or below 2000 rpm, avoiding the use of VTEC where possible (thought that's always a challenge with this car!), using cruise control wherever possible, and keeping aerodynamic drag to a minimum (closing windows/sunroof above 80 kph). Plus I'm usually sparing with the use of the AC. Hope this helps as a benchmark!

Are you automatic or manual? I have a manual type s and can get 32 highway and the worst I have ever gotten is 23 with really aggressive driving

Because you know, for sake of comparison.

Hi speed

iTrader: (3)

I was thinking the same thing. I'm getting 20-25 mpg ( 6 speed ) with the turbo and a rich air / fuel ratio. My feeling is average speed makes a big difference in mileage since most of my miles are on the freeway. The gear you are in makes a huge difference in the mileage you get. 6th gear is very efficient in the MT cars and if you can spend much of your time there, MPG is very good.

mau108

I'm averaging 29-30mpg on my Type S. 75% highway, 25% city. Whats the mileage on your TL ?

xiily

LOL... Ride or die. Just saw seven this weekend. Needless to say I cried like a baby.

Ive been driving my baby more then usual this week. AND i havent refueled since the day i originally posted this thread. still good on gas, i'll be letting the light turn on this time around. Its gonna be pretty difficult because i really dont want to let the needle drop below a quarter tank. but as long as it rides, i ride...

(was that lame?! LOL )

foxriderar77

Depending on your boost, the turbo may be helping lol. I find on the highway if you can stay right around 70 in 6th you can get like 32 mpg

polobunny

You still got a good 30 miles of highway left in the tank once the empty light turns on.

NBP04TL4ME

I regularly get 24 MPG and don't really do anything special to get that, but it's likely my commute. I had an 04 TL MT prior to my Type S and the mileage was just about the same. On both cars, my commute to and from work was on back roads with a few stop signs but no traffic lights and relatively flat. So avg MPH was in the upper 20's or lower 30's. On the flip side, I have never done any better than 29 MPG on the highway regardless of how slow or fast I drive I have ALWAYS gotten 400 miles per tank and it is well documented that when the low fuel light comes on you have about three gallons of gas left in the tank.

polobunny

You can probably get more than 29mpg if you put it in 6th gear as soon as it safely can. On the 5AT you can put it in 5th at around 38mph and torque converter full lockup happens at 50mph. So essentially, 50mph would likely be the most MPG efficient speed to cruise at on the 5AT TL.

NBP04TL4ME

It's in 6th gear as soon as I reach cruising speed............... Seemingly makes no difference. It's almost as if there is something preventing the MPG from doing any better. I do however see a drop as cruising speed increases.

polobunny

As you attain your cruising speed? That doesn't mean it's the car most efficient speed, though. There's a bunch of other factors however, and I would not really sweat it considering 29mpg is pretty good.

On road trip conditions in summer, doing 55mph in the right lane, my best has been 32mpg. Calculated using my own records and not the car computer as it seems to be slightly unreliable.

Lately I've been doing 20mpg, it's summer, my foot is heavy, a couple of passes in 3rd gear with other cars and my commute is city only. 1/3 less miles per gallon than when on road trip!

NBP04TL4ME

It's not an overall complaint as I am happy with 29 MPG Highway. In my 04 TL I was regularly able to get 32+ so I have been chalking the difference up to the 3.2 vs. 3.5.

truonghthe

the 3.2 get slightly better fuel economy than the 3.5 or at least that what I had been observe through the forum when people post their MID pics.

UPDATE: for anyone still following this thread.

i let the fuel light come on, so i fueled up. 12 gallons still. and was at ~300 miles to the tank. Trying Chevron this time. fingers crossed for average gas mileage

25 mpg is fine
