MrJimmy

Hey guys, I was just wondering what your average mpg is on your TL with mixed driving. I average about 19-21 mpg with 40% city and 60% Highway. I was wondering if that is alright for this car. Thanks

The TL is rated for 20mpg city except for the Type-S which is rated for 19mpg. You're doing just fine.

welcome to the forums!

as you can see there's a lot of threads about mpg. 19-21 is fine in my opinion. you'll hear people take pride in the fact that they get more than that and you'll also hear people complain how their TL is a gas guzzler.

if you stick around a little longer, you'll see other members start new threads about gas consumption.

don't forget to use the search bar!

Thanks a lot you guys! Much appreciated

your MPG look fine to me, I got 20 mpg and avg speed 26mph.

Why so many MPG threads at the end of the summer but not at the beginning?

^ idk but ydafuk is there a mpg thread to begin with?

I had something mean typed out but you seem like a nice guy. MPG is directly related to average mph displayed on the MID. City and highway don't tell us anything. The TL ranges from 12mpg to 34mpg depending on average mph.

ZOMGVTEK

I know everyone is big on the average MPH being directly relatable to MPG, but thats not always the case. Generally if you have a higher average speed all it means is you are stopping less. Going slower and stopping less is a better bet.







Driving the slowest possible in top gear for MT, or the lowest speed the torque converter locks up for AT is almost always the best MPG speed. This tends to be about 35 for MT and 45-50 for AT. Starts and stops absolutely trash MPG, you can easily get <5MPG going from light to light in heavy traffic. Generally you don't do this for a whole tank, so it gets averaged out, but technically anywhere from about 0-60 MPG is achievable. More like 15-30 for how most people use it. If you idle the thing in your driveway for 30 minutes in winter and then drive a short distance, expect <10 MPG. I know people that do this, so its not as crazy as some might think. They then tend to complain about it.

I hate cars

No.

ZOMGVTEK

I'm a bit unclear as to what you are trying to say. Are you suggesting driving at 70 will yield better average MPG as compared to 60 or 50? Does that also mean 80 would be even better?

If you are monitoring instantaneous MPG, its rather easy to notice how speed impacts efficiency. All the evidence I have points to low speeds and high load being nearly ideal.

chaddfaulk

I usually average about 22mpg in my '05...no complaints here!

I hate cars

That's a blanket statement. Stopping less brings the average mph up which is why average mph is a catch all for every driving situation. Stoping more brings average mph down. See why this works?
Again, the reason we use average mph, not instant mph. Driving steady state at 35mph in top gear with no slip in theory can get the best mpg. However, that does not happen in real life. The average mph catches the starts, stops, acceleration, etc.

Nope. Once you're up to a 60mph average speed it's safe to say you're on the freeway and driving steady state. Once you're in steady state mode, more speed means less mpg. In mixed driving, the higher the average speed, the better the mpg because is usually means less stopping and starting.
Only under steady state conditions which do not exist except on the freeway. Instant mpg and mph does not apply to the real world. You can get great instant mpg doing 35mph steady state but the first time you stop and accelerate, that 35mph average mph goes down significantly as does the mpg. It's safe to say that if at some point you're going 35mph steady state, you're not on the freeway and you're going to be braking and accelerating back up to that speed quite often. Again, the average mph is a catch all and it's been proven time and time again to be the most important factor in mpg.

danlib21

in my '07 I average about 26 mpg and I do a lot of highway driving near philly so the speed goes up and down constantly because people in PA dont know how to drive. On weekends i often drive to southern DE and I go about about 80mph the entire way and average 32 - 34mpg.

BeezleTL85

^ you can go 90 and it'll stay about the 32 mark. Out of my daily 150 mile round trip about 100 of those miles are doing 80-100mph and I get 30-32 all day, but my avg mph on the mid never says more than like 65ish

rydjohnson

23 city and around 31 highway for my 5AT

I calculate mine whenever I fill up. Usually it is between 26 and 28. The best I got was just under 32 and the worse was 24.

Pat04TL

Jimmy, our cars are getting older by the day. Unless the mileage drops dramatically and quickly (indicating a bad O2 sensor or God-knows-what), I don't care about mileage anymore. Not having a major repair bill to pay (which tends to greatly increase $/mile) is good enough for me...

4drviper

semi daily commute to school

dist : 157
time : 4:30
avg spd : 25mph
avg mpg : 25mpg

drive like a grandma and never exceed 2000rpm lol

LaCostaRacer

The Avg MPG=7 but Avg MPH=27 situation brings up a anomaly with the MID which must involve the differences in how the car was idled or driven. Fortunately, the big clue in the picture is the 5:10 time that tells me that car was idling for a very long time. To go 102 miles with a 27 MPH, it would take LESS THAN 4 hours to do that feat but yet it took 5 hours and 10 minutes.

What's up? Why did it take 5:10 minutes to do something that should have taken less than 4 hours to complete? My guess is you idled for a very long time or something.

Acura-OC

157/4.5 = 35 mph

Moe5193

HAHAHAH

2003av6

In the wife's tl she gets 23mpg on avg.

As long as i don't get in it!

LaCostaRacer

For you unbelievers of the MID, all I can say is how long have you been collecting your data? I have been collecting data for over 6 years and the MID is spot on. Both of you are not letting your tanks go down either so perhaps the MID is inaccurate in those circumstances possibly. I usually fill up just below the 1/4 reading uand have never had errors remotely close to what you guys are reporting here.

Acura-OC: don't know what to say. You MPG would correspond to the 35mpg (we have had threads in the past on the speed .vs. MPG chart), but the MID says 25 MPH.

ZOMGVTEK: If we use Acura-OC's logic and divide the distance by the time we get 19.61 MPH but yet your MID states 27 MPH. If all MIDs really understate the MPH as what Acura-OC is trying to say, you are way off and the MPG would truly be around 7 MPG.

Acura-OC

My MID is spot on with MPH calculations. MPH=Distance/Time is not my logic.

LaCostaRacer

^ Ok things are a bit confusing. How come 4DrViper posted 25MPH in the original data then? I'm inclined to believe the MID actually read 35 MPH too. A picture is worth a thousand words and in this case there was no picture. My guess this was a copy/paste error on 4drVipers part. 25 MPG would be a reasonable read if the average was 35 MPH- no issues there.

Do you guys ever wait for an entire tank before posting MID readings? I think you'll get much more accurate results if you did.

ultimatum127

18 MPG for me, i drive pretty aggressively though, but if the mood is right i can average about 26+ city and freeway driving 50/50 with coasting and timing sometimes even 30!

I hate cars

I take it you didn't read the thread.....

4drviper

SORRY i got confused with trip A -___- ;

here are the pics.

** I bedded in brakes 2 nights ago so..... that's why it went down to (i swear it was 26) 24mpG

LaCostaRacer

^ Yes- all the numbers make sense now. You have an unusually high MPG number for the speed though. Looks like it was a steady state drive of around 25MPH with little idling.

4drviper

nope. like i said in the original errorneous post, i just taught my car to sip with my right foot.

I idle a lot. like till 150F coolant temp in cold morning and when hot, takes time to hook up ipod charger and aux and punch in destination in gps lol and check gauges.

and,, because y'all racecar

I hate cars

The AF ratio is a constant for a given condition. The car learns certain things over time with the short term and long term fuel trims along with timing and other things. The car doesn't lean out over time though. There's power enrichment mode under heavy load and full throttle fuel tables as well but the ECU can adapt very quickly. There's no need to slowly lean out.

Factory ECUs are far superior to aftermarket in many areas. It's hard to match the drivability under all conditions of the factory. There are so many engineers and man hours devoted to making the car run perfect under any condition.

4drviper

well thanks for clearing up the techncial side of my explanation but you know how OEM ecu occasionaly sprays more-than-necessary fuel even if at the moment the car is driven lightly,
if you drive hard than soft, than hard, than soft etc.
(fuel, spark, shift, lockup, etc)

and yeah if aftermarket ECU was smart like OEM,, hondata reflash would cost 200 grand lol

AcuraTL-X

i own a 2004 acura tl 5at, and i do atleast 200 miles highway per week. So my average mpg is 27-28. If i do city while using sportshift and shifting at 2-2200 rpm, i do about 20-21.

I hate cars

I can't believe people are still posting half tank miles and mpg with no mph. Both are worthless.

nickn7

with 100% city driving i average 16-17 mpg and I would say i drive fairly passive for the most part (definitely not flooring it off of every red). Sometimes i just miss a lot of lights, but even at that i don't get any less than 15
