I don't care about mpg like everyone keeps asking about, but I do hate stopping 5 times a week to fill up. How many miles per TANK do you guys get?

 

290 miles/19/20mpg and sometimes even 21 if i dont push the gas pedal... this is mostly city driving.

btw i get 290 miles because i still drive the car when it says 0 MILES... so when i fill up the tank it only goes up around 15 gallons, so i guess 2 more gallons are still in there....

 

I get 220 on my current car 11 or 12 gallon tank
What is avg for a car, is 290 good?

 

I'm getting mostly 26-27 mpg but I do a lot of highway miles.

 

we weren't talking mpg, but miles per tank
thanks anyways :p

 

What's wrong? Can't do the math?

I usually fill up at the 300-mile mark.

 

no, no I can't
Y DON'T YOU RUB IT IN!
I'm sensitive you know

 

75% highway driving 23 mpg average i usuallt get about 300 per tank. when i fill up it says there are about 30 miles till empty. i dun know how accurate this is because if it is a 17 gallon tank like advertised and i am getting 23 mpg like the computer says i should have another 30 somewhat miles left. i think its hiding a gallon or 2.

 

340-350 for a tank. 14 - 14.5 gal per fill. 60 miles commute. 14 miles ity remainign highway.

 

I average 320 miles per tank and usually need to put in about 15 gallons. This is mostly suburban non-highway driving.

 

There, There.

 

I get 25 MPG City/Highway; Highway...80 MPH, 29 MPG...K&N filter increased MPG by 2

 

I never get more than 18mpg in my usual pattern of driving, which is about 90% short trips in urban setting and about 10% highway. Hence I have to fill up at around 250-260 miles per tank.

 

I'm averaging around 24 mpg, in mostly non-highway drving. Going about 270-280 miles before filling tank.

Getting K&N filter any day now (shipped just the other day). Hopefully that will help to stretch it out even further.

 

the 6MT gives a little more, I tried both.

my 6MT shows 429 Miles to empty in the MID, but in reality I get around 350 miles out of a full tank.
30-33 mpg on the highway (60-75 mph avg)

it all depends on your style of driving and how many stop lights you encounter...on your way.

 

SWEET!

 

240-280 miles on a tank. Mostly city driving with lots of traffic lights.

 

A K&N panel filter increased your mileage by 2MPG?

 

Yes it did, took about 1 month for the computer to learn and make adjustments for the increase in air flow. I could've disconnect battery so the car would've learned quicker

 

That's ridiculous.

Write Acura and tell them how they could increase fuel economy by ~ 8% simply by fitting the car with a K&N air filter from the factory.

I've used those filters in every car I've owned since 1989 (~ 10 of them). There was NO PERCEPTIBLE GAIN in MPG. Any gain that does occur could perhaps be measured in 0.00X MPG.

 

Believe whatever you want to believe, but I used it on my 03 TL and the MPG also increased by 2.

 

I get 19-20mpg, the idiot light usually goes on between 260-275 miles. It generally takes 14.x gallons, so i figure there's 50ish miles left in it.

 

Manufacturers go to extremes to obtain high MPG figures to meet CAFE requirements.

They'd ALL be installing K&N air filters as standard equipment if they were good for 2 MPG because the manufacturers could buy those filters for ~ $8 more per filter than what they pay for the OEM crap. That $8 would by FAR be the best $$$ per MPG investment they could make.

 

Do you really believe they go to extrermes? Come on you're not that gullible?

 

You think specifying an air filter that would cost them ~ $8 more per car to gain 2 MPG is "an extreme?"

Do you have ANY IDEA what (real) EXTREMES these manufacturers go to in order to extract an additional few tenths of an MPG?

A K&N panel filter isn't going to yield a 2 MPG gain in fuel economy, all other things being even remotley equal.

I don't think I picked up 2 full MPG in my LS1 Z28 with the COMBINATION of headers, a low restriction SLP "cat back," a K&N air filter and Bosch Platinum+4 plugs.

And trust me, the headers and cat back freed up that engine a LOT more than the air filter.

But you picked that up with just the K&N?

 

Real world, truly objective testing shows little to no difference between aftermarket "performance" air filters and (clean) paper ones.

This extensive test showed HP gains that fell well within the margin of error of the dyno. And if measureably more power isn't being produced, then the actual difference in air flow restriction to the engine can't be much different. And if those two things aren't much different, fuel economy won't be either.

Do have any reason to lie about it, I'm just stating a FACT!!!

 

I average 18-19 mpg with City Highway driving combined. Normally fill up at 260 - 270 mile mark.

.

 

You're stating a "fact" as you see it.

There are a HOST of other variables involved, all of which you've chosen to ignore.

For one, fuel economy tends to markedly improve as a new engine loosens up (with mileage). That process can take up to 5,000 miles with today's newer engines.

In order to PROPERLY substantiate your claim, you'd have to make the same long highway drive under similar traffic and atmospheric conditions (temp, humidity) with the cruise control locked @ the same speed using the OEM and the K&N filter (both clean).

You would then be controlling most other variables.

If you did that, you'd see there is no quantifiable difference in terms of MPG between those two filters.

 

Had the car since 31 Oct, apprx 48oo mile; one trip average speed 80 MPH, 29 MPG

 

not this flaming again. sigh.

 

Again, you have to eliminate every other variable before you can attribute a change of that significance to any single variable. And you have to PRECISELY MEASURE mileage.

I'm a mechanical engineer, have tested a host of fluids (both liquid and gas) systems and have been playing with cars (including air filter swaps) for the past 2 decades.

And I'm telling you that there is NO WAY that a simple air filter panel swap is going to produce an ~ 8% gain in fuel economy.

Additionally, it's worth noting that such a reduction in restriction on the intake side would yield a substantial gain in drivewheel HP (on a chassis dyno).

Stock '04 6 speed TLs dyno @ ~ 230 drive wheel HP on a properly calibrated dyno. Yours should produce SIGNIFICANTLY more than that if the K&N is capable of reducing intake restriction by as much as you claim.

Trust me, it won't.

 

Here, read this. This guy is also a mechanical engineer.

The differences between "performance air filters" and standard paper filter are nil on anything short of a full tilt racing engine that gobbles loads of air...

The differences in pressure drops between the "performance" filters and paper filters is next to zero.

And the "performance filters" don't filter out the dirt as well, either.

I am getting about 320 miles in a tank of gas. I don't bother filling the car up until after the trip computer say 0 miles until empty.
FYI
My first tank of gas, I ran it down to zero and it had exactly 3 gallons left.

Now when the computer indicates 0 miles empty, I reset one of trip odometers. I assume I can drive another 60 miles without the car running out of gas. I try not to run the car on fumes under cold weather.

 

350 miles until the idiot light turns on.

You 3rd generation guys must have leadfeet

 

lead feet and nicer cars

 

220-240 miles, 12-14 gallons, MPG 15-16, in city.

But, when cruising in Highway, I ever did 400 miles, 14 gallons, many times.

 

They only go to the measures they are forced to comply with and will always try to get away with whatever will save a buck on the bottom line.

The K&N is cost prohibitive and requires more work to keep clean than just replacing a filter. Imagine the calls from people when they read how often they have to clean and oil their new filter in their car. I doubt the average house wife or average Joe would be interested in such a deal.

 

Yup, and more horsepower.

 

They don't yield a 2 MPG gain (~ 8%) in fuel mileage, though...

Any gain that might exist is but a small fraction of that.
