The results are in and I'm somewhat pleased. I got 331 miles on a full tank which is roughly 14 gallons. I think there's 3 gallons on reserve but not sure I just filled up after the the gas light came on. Anyways it's an average of 23 MPG which is reasonable for a mix of highway/city driving. This was after just changing out the dirty air filter that was never changed before. My first tank made my heart sink, 200 miles on 12 gallons which averaged roughly 16 MPG, almost worse than my Yukon. I guess I spoke too soon about the factory MPG rating of 19/29, it's not a lie.

 

now read the thread on cabin air filter DIY
that makes the ac work better!

 

The air filter killed your gas milage like that? Thats crazy.

 

I'm not sure, but the wife wasn't pleased about the first tank. The filter was unusable though when I took it out. The whole thing was pitch black and it was the original Honda filter which I'm sure is the original from when it was brand new. I'm definitely gonna do the cabin filter DIY 01tl4tl. Thanks for the great advice.

 

This also points out the lack of maintenance this car probably had. You might want to check everything else out too. (Transmission fluid especially)

 

Yeah, I didn't expect it to be perfect considering it's a used car. I'm waiting til next week after bringing the car in to the dealer for transmission diagnostics. The interior is pristine and the exterior is great minus a cheap repair on the rear bumper. I'm gonna do everything in my power to restore the car back to new or at least close to new.

 

23mpg sounds right, and normal for mix driving.

 

do seafoam.

best way to calc mpg:
fill tank, reset trip counter. drive drive drive drive. fill up again. take the trip mile# and divide it by the number of gallons replaced on fill up. i understand that pumps might stop at different top off points, but in the big picture that difference is not significant enough to swing the number that greatly.

89 octane is the lower number, 91+ is the higher number.
i get btwn 28-31 all highway, 22-26 mix, 18 - 24 when i start and stop the engine a lot and all local nyc area driving w/heavy foot. i have an 03 tls w/50k

 

Will seafoam soon after dealing with the transmission. That is the exact way I calculate my mileage, I always reset the numbers at each fill-up and write the mileage on the reciept. I know that's a little anal but at least I have a record each time. I didn't know you can actually drive a car in NYC My friend lives there and doesn't have a car because it's way too hard to get to where you want to go but that's probably just his view on it.

your buddy is right, but obviously not a car junky driving in the city is like an arcade game. but you need to be like a ninja to keep your car in one piece.

oh yeah use tire pressure like 2-3 lbs over the factory spec to give you a boost and firm up the ride.

 

Just 2 to 3, thats it??? Mine were/are always 6-8 over

 

haha with the nyc roads.... you would have the most bulged tires ever. i ran 33- 34 with my oem tires. even then i still got a lump or two. i wish they made performance tires with a 200 load rating. that would make driving less active avoidance and more enjoyable.

 

Chanrith suffers from slipping trans- the mileage will improve after replacement
Then you learn to to drive without constant use of vtec and the economy begins to appear
Some new spark plugs will do wonders after the seafoam too

 

I did it and i never had any issues with tires and my car has seen every type of road possible, including logging trails. Hell my car has seen more off road driving than most SUVs on the road

 

i got less than 100 miles on my fresh tank of premium and my needles already at the half point

 

I get 470 freeway miles and about 380 city, mix at 425 and hit about 16 gallons in the tank so 29 freeway/23 city/Average 26 MPG.

02 TL 133, 000 miles. Again, nothing like a Honda

 

would driving normal and having air intake improve mileage drastically? sorry for noob question.

 

BWAHAHAHAHAHAAHAHAHAHAHAHHAHAHAHA

 

'00 TL 131K miles, 26 MPG in mixed driving. Nothing A/M except for a K&N air filter.

 

26 MPG is good. I'm hoping that the new trans will improve the economy. The service manager made the calls and my 110,000 mile TL qualifies for the warranty coverage. After the trans, I have to do the timing belt/water pump then it's on to seafoam and change of spark plugs.

 

I/H/E (Comptech) + pulleys + appropriate maintenance + frontal lobe telling right foot to take it easy = 28-29mpg mixed driving
