can anyone out there help me. I recently bought a 2003 TL and im getting less than 200 miles on a full tank of gas (city). Any advice?

 

change your driving habits, make sure your using 91 or better for octane, run some fuel injector cleaner like seafoam thru the gas (wouldnt hurt to do the whole motor) and 200 isnt that far off from the norm for all city.

 

Don't floor it everytime you go too

 

Would D5 or D4 save more gas while driving on a normal basis?

 

??? does the car travel at speeds where it can use 5th or does it not even get there or is it hunting for the right gear between 4th and 5th?

 

just on a simple automatic car is D5 or D4 more conservative?

 

what MPG are you getting?

 

At kragen, or I think any auto part store they sell this thing called a tornado for your air intake system (airfilter) that you put in the intake and it helps you save gas. I got it and well i got to say it did help, but i will advice it is kind of prici <-(cant spell lol) its around $64 thats how much i got it for but you can check.

 

Less than 200 sounds pretty bad. I do all city driving, mainly back and forth to work, and I get about 260 miles a tank. That averages out to 18mpg.

On top of what fsttyms1 said, make sure your tires are properly inflated(i fill to 36psi) and check your balance and alignment.

 

what do you mean?

 

It depends on the speed you are going. Of course D5 is always better if you are going 50mph or faster. D4 will take more gas.

 

yea i get around 300 with all city driving.. which isnt to bad... i suggest u run fuel cleaner or some sea foam....

 

Just searched, this thread seems like itll help me the most.

I have clocked just under 50 miles per what almost appears (almost, but not quite) 75% tank remaining (based off my fuel gauge). Is this normal? I use 92 octane.

What were TL's rated for? I hope I dont have a heavy foot.

I have 90K on my 2000 TL. Ordered some new Iridium 9's, and will sea foam as soon as I get it. Timing belt is right around the corner.

 

TL repin
take the tornado back off and return it- it has been proven to conflict with the vtec mode in the engine- works great on my old truck though! no vtec no vortec uses for the nado

city -19
hwy 29 normal-32 outstanding
combined driving 23
Used TLs get lousy mileage until you seafoam, ngk, air filter of choice and cabin air filter
Thats usually 2 or 3 tanks of gas and you decide to reserve the use of vtec for
~as needed~ instead of all the time

 

Is your check engine light on? Does the car have a rough idle? Right now I get about the same- 200 miles to a full tank but it is because I have a ignition misfire that gives my car poor performance and horrible gas mileage. I am in the process of fixing it, but i get get about the same due to a misfire.

 

That doesn't sound good but you cant calculate mileage from the needle, you have to fill it then next time you fill it you divide the amount of mile with the amount of gallons put in

 

The guage usually says you went 200 on the first half then it plummets
It should only be used to know when to fill up again

 

 

Under 20 MPG with all city driving is TOTALLY normal and expect for this kind of car. There is nothing wrong with the car.

 

I do all city driving (and short trips to boot)...and I get around 16-18MPG...

But I have also taken my car on a long highway only trip and logged 30MPG...

Normal....

 

I do a lot of driving city and highway, that sounds a little low I have never had less than 270 miles to a tank. normally I will see about 350-370 sometimes depending on how much city driving i do. I use 93octane and cruise control a lot. I've seen 30mpg also on highway driving, and around 15-19 mpg on city.

 

Im currently at 254 miles per tank so far. My orange light has been on for a little bit. About 40 miles, I completed the seafoam project as well as using the Iridium IX plugs. Those two items sure did make a difference.

All my driving is city.

 

I get 292 miles driving in low RPM's on the manual mode.

 

help me out here: how much more mpg do you get after seafoam, ngk and air filter.
how does the cabin filter help with mileage? you mean by reducing electric load and hence engine load?
how do you choose to engage/disengage the vtec?

 

I have a 2002 TL Type S and I get about 375 miles a tank, iridium plugs and a CAI with a K&N filter

 

what's this cabin air filter?


EDIT: nvm, i found out http://www.car-stuff.com/cabinairfilter.htm
so where is this located in our cars? thanks

 

It's behind the glove box. You have to remove the glove box to get to it. It's not hard and if you do a search for Cabin filter DIY, you'll find an excellent thread with instructions and pictures. I did mine about a week ago (that thing was FILTHY! ) and it only took me about 20 minutes.
