ok i filled up my 05 tl 6speed with 93 gasoline and about 186 miles later im on empty .... smh ... im think wtf im pissed. this has been the case since i got the car. no im not a speed racer and yes i do most of my driving in the city but damn 186 miles thats crazy. last onth i changed my air filter, oil, spark plugs and also did the injectors cleaner from advance auto is there anything else that i can do?

 

How many gallons did it take at fillup?

 

the car was on empty.... like bout to shutoff and i filled it up and gas was bout 4.24 for premium and i remeber it came to 66.03

 

Maybe you have a leak somewhere?...check after u pump gas..drive it home and park it..look under the car see if its leaking??

when i first bought my TL ...

my first tank ran me 220 miles...i got iffy and started cleaning and changing spark plugs

my 2nd tank..ran me 270 miles...

my 3rd tank i ran 320miles... with 14.1 gallons

im currently on my 4th tank and hopefully runs better

 

I would definitely check if there is a leak or something. When I drive like a maniac I get at least 260 miles on a tank.

 

If my math is correct that works out the about 12MPG. What does your MID say the mileage has been? I've read some people getting mileage in the mid low teens with purely city driving. Maybe you should try to change your driving style and see how much it helps.

 

thats pretty bad mileage, i drive alot of city but i still get about 17 mpg.

 

i get an avg of 23 to 25 miles per gallon now...17 is a bit low

 

might be an ecu problem? Reset ECU by disconnecting battering for a few minutes and re-attaching. Maybe the previous owner had a lead foot and the old ECU setting are stored. MAKE sure you have the radio codes!

 

That's about 12 and I'd say it's a little on the low side, but I'd check the mileage over the next couple of fillups to be certain. If a lot of idle time and traffic jams, it's possible as the EPA has 18/26 for the '05 and the EPA test:

The city test is approximately 11 miles long and simulates a stop and go trip with an average speed of about 20 miles per hour (mph). The trip lasts 31 minutes and has 23 stops. About 18 percent of the time is spent idling (as in waiting for traffic lights). A short freeway driving segment is included in the test. The engine is initially started after being parked overnight.

I'm getting at least 325 to a tank with the turbo and double sized injectors. Sounds like you have a fuel leak to me or someone is syphoning out your gas. 180 miles should be closer to a half tank. Check the Mid to look at average speed and MPG.

 

is the number showing on the trip computer reflect the mpg? mine only shows 15 but i think i am getting 22 combined

 

try resetting your computer... it helped on mine gained about 2mpgs

 

Sorry, but these fuel mileage threads get old. If you stay out of the gas, your mileage shouldn't change much at all, regardless of the turbo and injectors as the turbo would be idle and the injectors are governed by the electronics. Our RX 7 Turbo with 14lbs max (7lb factory) and larger secondary injectors doesn't change the mileage as the secondaries only come on above 3600 and then all 4 dump fuel into the chambers.

 

How many miles are on the car? It may be time for some maintenance.

 

ok i have 97k on the car and i check the trip reader it s said 13mpg and an average speed of 13mph
