How can i increase my mpg?
Hello all.. I own an '01 TL and this thing is giving me around 110miles at half tank.. I have no mods to the engine at all. I replaced my spark plugs, new tranny, and seafoam.. I do have to replace my timing belt as the other one is bad.. What can i do to improve my mpg?
I drive city most of the time. And I do NOT floor the car at all. I get around 11-17 miles.. And at 17 miles, thats mainly highway.

make sure tire pressure is up to spec, maybe even go a few psi over, get rid of any unnecessary weight in the car, coast whenever possible, and accelerate slowly and smoothly.

city mileage in the TL isnt the greatest for most. There is NO miracle way to improve mileage.

I have tried changing this and that for MPG...but what made me get better was actually changing how I drive. I have a leadfoot and even when I THINK I'm being good, I'm not. I recently started scrutinizing the MPG displayed while driving and I've managed to increase by about 3mpg that way. It made me more honest with myself about my driving habits.
That being said...don't pay attention to the needle...In my RSX...I could swear to the MILE where the needle would be...(on fillup would take 37 miles for the needle to move, etc) In the TL it seems different EVERY TIME! Driving chill this time though, I have been able to hit about 160 miles at the halfway mark. Probably a 300 mile tank, I'm hoping.
Hope this helps. Good luck.

80 miles at halfway mark 
stupid stop and go traffic
but normally, i get about 18-20 mpg city which isn't bad for this car i suppose. i try to keep the revs below 2500 (before u call me a grandma i keep up with traffic just fine, thank you). and i do a lot of coasting.

i went from 310 on a tank to 423 in two different weeks because i changed driving habits.. im at 415 at the moment with 1 notch left...
driving habits do a world of difference.. and im not a lead foot either, just accelerated slower and drove 70 rather than 80-85 on the highways...
100+ miles...
