When you fill up a full tank of gas, and drive with a fairly light foot, how many miles to you get from one quarter of a tank, half a tank, so on? Also, on my 2001 SE automatic, my tach sits at 2900-3000rpm at 80mph while cruising on the highway. Is this too high, or is this about normal.

 

fairly light foot city driving probably between 250-300 on a full tank if im lucky. 300+ on the highway.

at 80 mph im a bit under 3000 rpm.

 

at 80 mph, i am at about 2300 rpms.

i love my 6 speed.

 

I'm at about 3000 rpms at 80.

 

My commute is 40 miles one way with 95% highway.
I usually drive in the 80-85mph range on the highway.

Just for fun... on my car, it is 60 miles when fuel gauge points to F
(way pass F after fill up); 120 miles at 1/4 mark;
230 at 1/2 mark; 340 at 3/4 mark. Light usually comes
on at about 380 miles, when there is about 2.5-3 gallons left.

More accurate calculation yields about 25.5-26mpg almost
every time.

 

I must be in the minority, and very frustrated. I get only about 21 mpg even if I drive like and old lady, and the mileage is even the same at 70-75 mpg on the highway all day long. My high low mileage records are 17.5 - 21.9. I run 93 octane (91 since prices skyrocketed) and that make no difference either. I have an 03' SE with 24,500 miles on it. I even just replaced my air filter and that made no difference.

Any other suggestions?

I get about 90/175/250,280 by tank quarters.

 

yeah man I dont know what it is....maybe someone can help, i always fill the tank past F and i do a LOT of highway driving but i dont think i've ever got close to 300 miles to a tank. usually at about a half tank it'll read about 100-125 miles. I have an '02 GLE with 57,000 miles and i just changed the air filter at 55,000. any ideas? fuel filter maybe?

 

I noticed that I get better mileage after I reset my ECU. Then after a few starts the mileage is down to 18 again. Something must be causing my ECU to change - maybe changing the fuel mixture(?). I'm trying to track it down now. A new MAF didn't help much.

 

i get about 18 mpg, mixed city/highway

so do most people in New York.

 

My car is doing exactly the same thing.

 

You definately have an issue with your car take it in before the 60k Powertrain warranty expires, it seem like you drive quite a bit with that mileage on an 02. Your gas mileage is very low (we all know the 3.5 drinks) I usually fill mine past full and get about 1000-110 miles to the 1st 1/4 of the tank and after that the gauge falls like crashing plane. I usualllly get about 280-302 miles a tank with mixed driving what about you?

 

Your car is normal (we get about the same mileage at the same points except I usually get about 100 miles or so on the 1st 1/4 tank) mine is the same way these cars drink gas, my 350 is the exact same way.

 

WOW!!! so many of these threads have caused me to know that something is wrong with my car.
I have a 2k se, 54k miles, and when i fill up (usually only fills up 16 gal.) i noticed i will only get to about 220 then the light comes on, thats if i dont floor it etc. I wish i could get near 300 a tank, then again i do live in nyc and am in traffic and usually sit in my car for lik 15 minutes at a time without moving so...

My last tank of gas (15.5 gallons) got me 411 miles which was astonishing. I have 108k on my 2k and have never seen this. I average 320-360mi per tank.
Granted I did clean out my K&N.

 

I get sh!tty mileage too (NYC). 47000mi, new plugs, berk intake, new MAF, no apprarent problems.
I got a scantool, so ill check all my sensors, but I dont really know what to look for, like, which reading would be abnormal and which would affect the mileage.
