I've driven 1000+ miles on my 98 GLE now, and my old trusted "# miles driven/actual gallons pumped in" calculations show an avg of 25.5MPG in mixed driving.

With 170k miles, that's not bad at all!

 

No man, pretty good!

 

I just picked up my 4th gen and drove 130 miles and just ticked under the full mark on arrival. Pretty impressed. 194k.

 

Yea, these cars seem to be pretty reliable with a decent amount on the clock. And to boot, they get good mileage!

 

I get 25 mpg with the turbo. Mixed driving also. 400 miles per tank, 93 octane. I get 380 per tank with 89 junktane.

 

These are some pretty good numbers. I'm getting around 230 miles a tank in my car. Sucks, only 62k on the clock and gas here is around $4.40 a gallon but I do all my driving in the city.

Honolulu is traffic ridden and nothing but stop and go. My gauge says it's averaging 17.7 mpg, so I guess I'll take it.

 

I average about 26 going back and forth to work, but today i took a 150 mile trip and returned 30 mpg on my 95 GLE with 180k

 

Better than mine... I average 18 to 23mpg, usually around 20. Damn lead foot but the go-fast pedal sure makes my Cattman Y sound

 

That's one of the things I liked about my 4th gen...good gas mileage, even with over 200k on the clock.

 

I get only 19-21 MPG. But at least its been consistent, lol

 

I can't keep my foot off the gas either.
The TCW-3 did help my milage, and I switched to the 17's recently; so that helps I'm sure, but I'm still averaging 16mpg~all city.

I took one highway trip with the 18" G35's and that threw my mpg up to 19, but that was only about a 40 mile drive.

I'm going to try harder to shift earlier or just into a higher gear, but the sound is

 

28mpg pure highway driving. 13 mpg in NYC.

300k on the clock

 

My 95 GXE with over 223k has been getting in the 21-23 range lately, down from an average of about 25. Going to replace O2 sensors this weekend since they look like they're original and see if that helps any.

 

My mileage is getting better still not good. For some reason getting a CEL for the coil packs but no misfiring. Computer playing tricks on me?

 

do you have aftermarket coils?

You can't always feel a misfire too btw

 

That is pretty good for mixed driving.

 

No misfire codes

 

seen some good mileage results posted here. on my last 3 fishing trips on mostly hiways doing 55-60mph, i have gotten 30, 29, and 31 mpg in my '97 maxima se. getting better with age. 206,000 miles on odometer.

 

After market coils usually have the wrong resistance value built into the primary winding, causing a DTC. This is a well documented issue and as already posted in your own thread, buy new or used OEM.
