i used to get around 215-220 on a tank of gas, now im getting 300.

i got 300 miles and filled up using 10.89 gallons, thats around 27 mpg. im guessing thats a pretty good number since i drive mostly in the city.

 

i used to get over 300, but now i get around 265-275

and i don't drive as fast as i used to anymore...i'm getting old

 

I need a new cone filter.

 

i don't even know how much i get, lol. do you used the trip meter to fing out?

 

Drive until your tank is just about empty and your riding on fumes. Fill up. You should be able to put somewhere around 15 gallons in if you were totally empty. Then drive until you run out of gas. Then divide the number of miles you went since the fill up by the 15 or so. Thats you MPG. If you were doing all city driving, its your city MPG, if highway, then high MPG.

The downside is that you will be out of gas in the middle of the Nevada desert.

 

Good job! I must say that I'm pretty lucky with my 27mpg fuel economy, especially since I drive in DC rush hour traffic every day.

 

yeah you're dc traffic does suck, why not just take the metro rail?

 

no need to guess at "15 or so" when you fill up just look at the exact number of gallons that were pumped into your tank from the reciept or the display on the pump. Divide that into the number of miles on your trip meter since you filled up last and you'll have an exact number.

I keep a spreadsheet of my MPG on every fillup just for kicks.

 

On long road trips I can break 400 miles per tank easily (usually without the fuel light). Once I get up near 420 I start to question my fuel meter if there's no light by then. As long as I don't go crazy fast - try and avoid letting the VTEC kick then I can see 30+ MPG.

I don't understand why your guys' motors don't do the same.

 

from my house to Chicago is 400 miles it took 12 gallons of fuel MPG = 33 at 70 with A/C on

 

i only get about 300-320 miles outta a tank...it sucks...it used to be about 400+...i dont know what happened...

 

I wonder how non-engine modifications affect mileage. THings like aggressive tire tread, altered suspension (aerodynamics of a lowered car), etc.

Any ideas?

 

well you kind of answered your own question, you said when you were on a 'road trip' and b/c you were traveling at a constant speed on the highway your mileage will be much better than the city. in the city(where most of dirve daily), there is more stop and go traffic and that extra effort to get your car moving from a standstill uses extra fuel.

 

B/C my contract does not subsidize Metrochecks, rather they pay for parking. Hey, my commute downtown is ~20 minutes, and my car is currently 40 feet underground in a nice, cool garage (definitely on a bonus on a day like today where the heat index is 109 )

 

nice, i wish we had parking like that at honda...our parking lot sucks ***.

 

I can usually go 420ish miles before my gas light comes on. Oddly on the road trip i went on last week, i barely got to 400miles, we traveling fast thoung, 90-105 for 4.5hrs w/ the AC on.

 

What about the gas that was in the tank before? Even if you run out of gas, there will still be gas in the tank.

 

It doesn't matter. STart with a full tank set trip meter and drive. when you fillup divide number of miles by the number of gallons that went into your tank. Why would the gas left in the tank matter. all that matters is how many miles you drove and how many gallons you used which you find out when you fill up next time assuming you started with a full tank the first time.

Its not rocket science were talkin here.

 

Its not accurate either.

 

sorry, but had to jump in here. how is it not accurate? it is perfect. As long as you start with a full tank of gas. and then when you fill up next time to a full tank you see how much gas you used.

 

If you don't top off and overfill your tank it is a precise measurement. I'm not sure what your missing...Its simple math. Not everything is as hard as it seems. No offense but if I could say it slower for you I would.

 

it works like this

1. fill up the tank to auto shut off on the pump
2. reset trip odometer to 0
3. when you fill up again note the # of gallons in this example we will use 12
4. look at the trip odometer in this case 400 miles
5. divide 400 miles by 12 gallons and you get 33 if you round to the nearest gallon (actually it is 33.33...)

it is accurate enough that you will never run out of gas if you refill knowing that x miles means you have used y gallons

I always refill at the time gas guage reads 1/2 that is about 8.5 gallons for me on 245 miles of city driving with A/C on

 

wider tires would make more rolling resistance, probably reducing milage
a softer tire compound would also reduce milage
lowered cars are more aerodynamic which would increase milage
with i/h/e you will usually increase milage unless your foot becomes heavy
but once you modify you're fuel system you're gonna head downhill

 

i've always gotten better milage with a K&N filter...and MOST people do also...

 

maybe b/c my old weapon r intake(rice) was crappy and the filter was filthy.
