After doing the above, i now get at least 2mpg more than i did before.

 

I got 250 miles on my first tank but I also got a 105k service (timing belt, spark plugs, fluids, etc) so its not really a true measure...at least I hope not. Plus, my tranny just went out so I won't know for sure for a couple of weeks. Just filled it up with 93 octane though.

 

just cleaned out my intake mani. looling forward to see what i get now

 

I guess my car gets pretty good mileage. I did a 380 mile trip with 5 passengers and trunk full of luggage and still had 3 lines above E. Then drove 30 miles and then the gas light turned on. All while sometimes doing speed limit to 10-15 above.

 

It's easy to get 400+ to the tank doing consistently all highway. I wonder if anyone pulled 500 when the gas light first comes on.

 

Key to good gas mileage:

Don't live next to people.

 

415-450 on a topped off tank... 130K miles on the ride, with like 50K being put on in the last year. commute went up, which blows, but the tl is going strong.. RIDE IT TIL THE WHEELS FALL OFF!

 

i've gotten upwards of ~475 doing 75mph from nashville to florida. but that was 40k miles ago

 

with clean internal engine parts and good gas- serviced- oil fresh -tire pressure etc etc, the car should run like new till you get rid out if--and get great trip gas mileage
Only reason not to is time to clean egr ports <g>

fsttmys motor at 200- looked factory fresh inside- with very little wear in the cylinder walls, where most wear occurs in engines

 

im at 171k on my 2002 TL-S

drove from Fresno to LAX all on one tank last week. had the cruise control on and kept it at about 75-80mph.

gas light came on about 5 miles from home..i think the total mileage was about 458 miles

 

Damn you guys get some good mileage. I got like 240 miles before the gas light came on. But I live in the city so I do really bad. That driving was like 90% city and 10% highway.

 

Driving city will lower your mpg significantly.

If you haven't done the EGR ports, clean the TB plate, and seafom the engine then you should. It'll greatly improve gas mileage.

 

I'm at 420 or so, and still a few ticks above empty. This'll be the longest full-to-light yet.

The Seafoam [fuel and crankcase so far] made a decent difference.
The biggest economy increase, however, came with new plugs, engine air filter, and running 93.

 

Ya 20 MPG average sounds about right. City isn't too good but if you do more highway miles you'll do much better. I got a 19 MPG average on my 03 TL during the past couple weeks.

 

I've got an '02 TL-S, got only a K&N air filter; haven't ever changed any timing belts or anything or used any fuel treatments, never changed spark plugs etc, use 91 gas, do mostly city driving, w/ some minor freeway (highway driving), get between 18-21 mpg. Lucky to hit the 300 mile mark before light turns yellow if mostly city driving.

 

I would say I get pretty bad gas mileage, but I have a feeling thats due to my style of driving and a little do do with the car. I would say I drive 70% highway and 30% city most of the time. But I'm usually driving around 80. Then there's the usual people in the fast lane who drive slow which cause me to slow down then I have to go around them and step on the gas, just wastes gas there. I know I can save gas by slowing down, but people still need to learn the rules of the road! The farthest left lane is only meant for passing!!!!!!!

 

I hit exactly 250 with my last fill up of 93 octane. Filled it to the top which was roughly 17 gallons. MPG came out to 14.705 so its safe to say I get about 15 MPG and this is all city driving, but some roads are more open than others (speed limits, traffic, stop lights, etc.)

 

Your gas mileage isn't very good. I typically get 21-22 mpg in mixed driving - 50% surface, 50% freeway. but never any lower than 19 mpg. So you added 17 gallons and only got 250 miles since your last fill-up? Wow.

 

well being in the city its more stop and go than anything. i just filled it back up and im changing a few things around with my driving habits. any recommendations on ways to improve my mpg's? what exactly does the seafoam do? ive seen that a lot of the forum users have used it.

 

plus all i have is a k&n box filter. any other modifications i can make to add to a higher mpg?

 

I get about 22-23 in town. 29-30 on the road (Loaded doing 80).

 

300 city/ 420 highway
