^ Don't misinterpret the MPH thing from the previous post to mean "The faster you drive, the better MPG you will get". Yes, if you can maintain a high speed cruise that will be ideal. But racing from light to light as fast as possible will give you worse fuel economy.

How would a clogged air filter not effect gas milage? If you are not getting good air flow it will not run efficient.

How about over 2 years of info- would that sway you into believing in the MID? Check out this link and you'll see what I mean:

That mid seems to says it all:
Low avg. speed of 22mph over 1800 miles @ 15mpg = lead foot + city driving.

Time for Sea Foam treatment... It works wonders. Have you changed your plugs ever?

The low mph aso means hes sitting at a stop a lot or sitting in his car with the engine running. The fuel calculator is still working when you're just sitting with the engine running. Keep that in mind folks.

I hate cars

Air fuel ratio remains a constant. More air=more fuel=lower mpg.

This myth originated on carbureted engines and it was real on those engines. A restrictive air filter was the same thing as having the choke partially on. It resulted in a richer mixture and less mpg. On a fuel injected car, AF stays the same no matter what and the only thing you can lose is power from restriction.

+1.
Myy MID is also very accurate at the pump, 24-26MPG, mix of 65% HWY, 35% city. Pure HWY I am usually around 28-31MPG. Reset w/ each fill-up. I also do a hand calc, based on Gallons put in and total miles on prev. tank. They are remarkably similar, always within 1mile of each other.

I always us premium fuel hereby get 93 Oct I just reset he mid yesterday ill see how it goes

Cool, keep us updated. If you reset it at every fill up, you can gauge how your driving style effects your mileage. If you see you're getting 13mpg for the first half a tank, it might prompt you to lighten up your foot for the other half.

quicksilver10101

I second this. Exactly what I get with the same conditions...if you driver her like shes meant to be driven, the MPGs will drop into the teens. If your driving like miss daisy with those numbers, there is def a problem!

To add another point of data regarding the MID, I filled up today at a calculated 21.9MPG, and a MID-indicated 22MPG. The MID is damn accurate.

supra98

yea, just got new plugs. No seafoam yet.

Well def try that. would you like the hd youtube diy vid thats on a j30 Accord.

I reset mines after each full up

i'd say yes, i normally get >385

Boostedsti

I get around 17 mpg atm. Im not thrilled since my STI was getting about 15-16 mpg, maybe its because I drive 9 miles to work 1/2 in city, other half on freeway that has hills at times. I do get good MPG when i take long road trips though...

Chad05TL

I hate to tell you this but you're not getting 35 mpg. Thats way higher than this car is rated. But mine used to say that too, but then it mysteriously changed to something much lower. The best way to tell is check how many real miles on the odometer you get per fill up. The old fashion way.

Chad, that is not my picture.
I simply found it to show Josiel that one says MPG and the other says MPH
if you look at the distance traveled with the corresponding time, you'll see why it reached 35 MPG

Chad05TL

and coasting.. haha

ParaSurfer1979

I get 33-34mpg in mine. When you live in flat areas of the country where it doesn't take as much effort to get to or maintain speed, then mpg should be higher.

Chad05TL

Have you actually checked it manually? Like with a calculator and reading the gallons on the receipt... You can't trust the dummy thing.. Because nobody gets more gas mileage than what the car is rated unless you lightened up your car.. but even then I would be surprized to see more than what it is rated. Manufacturers always rate at maximum mpg. And they rate their cars at optimum conditions and perfect tire pressure and all that.. Probably on a nearly empty tank too.. And since they rate at maxium MPG, and its a lot lower than your "33-34", then thats proof that your gauge is messed up because "AVG MPG" is always LOWER than just "MPG".. which is maximum.

So with all that in mind, you can believe what you want to believe.. but my question is, why are these 6 cylinders rated at 19 in the city when a corvette is rate pretty clsoe.. like 16.. And thats 400+ horsepower. Sounds like Acura needs to step up. I assume that is optimum also for a vette and no heavy acceleration.. The hwy mileage is about the same.. http://www.fueleconomy.gov/feg/bymod...Corvette.shtml

loc05tl

mpg is one of those things you shouldnt be worry about in a TL man. for how nice and powerful it is, getting 18-36 mpg city/highway is pretty damn good. Thats what i have all the time, just 20 ish. I live about 305 miles from vegas and I actually did make ONE WHOLE TANK all the way up to vegas. pretty sweet huh ? all freeway at 70-80 mph.

ParaSurfer1979

I've used a calculator if you are asking me because you quoted no one... As far as mpgs for cars. If you look at the paper on the window, there is a range foe city and hwy mpg

yiujai86

I've used the TL for food delivery in the past 2 years netting over 50k miles (don't ask, it's either the TL or the ES) which means all city driving. Lead foot give likes 12-14 mpg and normal driving gives up to 15-17. To get anything past 17 mpg on pure local mean I have to roll up to every stop light, grandma style the pedal and drive 15 mph between stop signs. Highway is like 31 mpg @ 65-70mph.

I've noticed local to some people means the speed limit is 30mph and for other the speed limit for local is 45mph so everyones local mpg will be different depending on where they live; rural or urban.

smarty666

Cold weather makes the car work harder. No matter how you drive, the mpg is going to go down in the winter time. I get 23-24mpg avgs now compared to the 27mpg avgs in the spring and fall.

TJK715

You can do the sea foam and plugs wires thats good but that will not make a change, the air filter will if its really bad. I drive for work and have over 500k miles with several different cars. I have always checked my MPG's just to keep tabs on the car. Things i have noticed that make a difference in the MPG's. The biggest one is how you take off from a dead stop, such as stop signs and stop lights. If you give it hell and give it full throttle at a stop that seemed to make the biggest diiference. Barely pushing on the gas and slowly rolling to your desired speed, yes you will not have fun and look old but what do you want MPG's or fun. It cost money to have fun. All the numbers that everyone has provided are accurate and the MID about the cars Average Miles Per Gallon is dead on + or - 1. I ve used 87 and 93 and the mpg's seem to be about the same. Once you have had the car for a while the mpg;s will get better. Or once you get a few speeding tickets. 15-21 around town 30mpg on the highway. Keep in mind If you let your car warm up like I do in the winter for 15-20 minutes that will contribut to the lower around town mpgs. If you you dont have a copld air intake that will help for a few.

I would suggest, when you reset it,do it when your on the highway so you start off with a good number then you work your way down due to the city stop and go much easier to keep the mileage higher.

Its like in school when you start off with an "A"(good mpg). As you do your thang correctly you can keep the "A" then if you started off with the "F" and tried to work your way up to the "A", but if you reset right after you get out of the gastation you already start with the "F" due to the city stop and go which already kills the mileage.
