Ive been noticing bad gas mileage in my tl-s, im getting 16 mpg sometimes it even says 15, I dont lay my foot down on the gas to much, only every once and i punch it just for fun, can it be the CAI i recently installed?

Reset ur ecu, or something.

your car should start to get better MPG as it breaks in

a CAI should give you better gas milage usually from 1-2 MPG. car runs on air+gas better air flow with the intake would only increase mpg

If you're blasting your A/C and sitting in traffic, you'll get 16 mpg
What's your avg. mph?

23 mph, and i believe my car is past the break in period, ive had it since march, or maybe it isnt? im new to this stuff

i get about 16-18 mpg in the city, 24-26 mpg on the highway ... i have a 2007 TL-S

say when

I don't know how the tl works with a cai but on my evo the cai makes the car run richer. With out a tune it would get less mpg's. I have no idea if the tl is the same or not.

it just seems like when ever i punch it, and maybe a minute later ill look down and the gas gauge move down maybe two bars , it just seems like its going through gas to much

That sounds about right...I'm getting roughly the same with my '08 TL-S. I don't how some of these guys claim that they're getting 23 MPG and up in city driving. Better than the EPA estimates? Wishful thinking I guess...

im guessing everyone with a tl-s uses the premium gas as the manual says?

I am getting 18 MPG @ 23 MPH. But it's been less than 1000 miles since I installed the CAI. I need to see where is goes over the next 2000 miles or so.

Prior to CAI, I was at 17 MPG @ 21 MPH. That was over ~3700 miles, mainly moderate traffic city commute.

how many miles on the car?

Raise your tire pressure to 35 PSI all around. Also use premium fuel.

When you did you CAI install, did you move the sensor to the AEM pipe or to the factory location. When in the AEM pipe, you loose about 2 MPG

there is about 3800 miles on the care and i do use premium, the cai was installed only a week ago and yes i did move the sensor, ill raise my tire pressure and maybe that will help, thanks for all the replies so far, really appreciate it

It's bound to be in how you drive. There is so much discrepancy between people's gas mileages is ridiculous. I for one have an 08 TLS 5AT. I "beat" on my pretty regularly and I've never once got less than 20mpg city. Right now my MID is at 24mpg 31mph after about 1000 miles on the MID.

I go WOT at least once or twice a day, and use SS mode daily.

Car has a total of about 5000 miles.

what do you know? i got into the car today and the check tire pressure light was on, that might solve the problem, my front two tires were at 28 psi

Bearcat94

Agree. That's why average speed is good to know as well. Look at yours and mine.

You've never gotten "less than 20mpg". I've never gotten more than 20mpg. Even though we'll both go WOT frome time-to-time and drive "city" miles.

BUT our average speeds are almost 10 mph apart - you're running at fuel effiecient speeds more often than I am and/or I am sitting at idle more often.

Move the sensor back to the orignal place, raise the pressure and also don't do so many WOT runs..

CBP TL-S

Yes most deffinatly. I'm not sure where you live because of your fancy latitude and longitude location . I would figure if you lived in a big city with heavy traffic those "city" miles are much more harsh than my city miles. I live in Jacksonville FL, my " city " is pretty spaced out so its not as terrible as say driving downtown all day.

My deal is if your getting at about or at least what it says on the window sticker of the car your ok. People getting better gas mileage than you isn't because your car is broke and the car is so new.

Population growth has been brutal regarding traffic the past 10 years. Roads have not been *close* to keeping up. It's not ATL/Boston/NYC, but it's bad enough.

To OP, I think it's pretty normal if you are only driving in the city.
