I have the worst e46 for gas mileage. I get 16 average currently, and that's with 23 on the highway.

Winter driving, heavy wagon and AWD, heavy wheels, high revs at highway speed, plus who knows what else. At 80 mph, the car revs close to 4k.

We have different diffs. My wagon weighs 200 lbs more than your AWD sedan and it's expected to carry lots of weight so they changed the diff to give it better acceleration.

Damn I'm a 2.7-2.8k in my xi and that's on a positive grade at times.

You probably need new precat o2 sensors.

Rpm is fixed to wheel speed in any given gear. Grade doesn't matter. You may need a new clutch.

I've been thinking of this too. She needs work and although there are no codes for o2 sensors, I probably wouldn't get codes even if they were bad. That's what I've gathered so far in reference to them. And besides those, I know that there are other things which need help as well.

I have an automatic. I was implying that even with an incline I don't need to apply that much throttle to maintain 80 mph.

Man, I want those wagon diffs! I'll bet sedans would scoot with 'em? Gas mileage? Meh - scoot wins.

Sorry. Just dreaming.

According to bok choys, we both have the 3.23 diff (if you have a manual). I thought the sedan and wagon came with different ones but apparently not, it's just the automatics that came with a different one.

Considering this, what are you revving at during 80 mph highway cruise?

Was wondering what rpm you guys are turning at 80?
Seen a few different responses on this from sedan people.
My 02 sedan 325 manual turns about 3500rpm at 80, seems a little high but my clutch doesn't feel like its slipping. I have seen some people say they are turning about the same rpms, and then I also read people saying they are doing ~2800rpm at 80mph in their sedans. So which is it lol?

It depends on what transmission and diff you have. Typically, the 5 speed autos rev lower at highway speed than the 5 speed manual.

I've come to the conclusion that the Expedition isn't really big enough for my needs and have begun my search for an Excursion. I fear it may not fit in my garage...but whatever. The V10 ones are way cheaper than the diesels but we'll see what I end up with.

Back on the gas mileage front, we got a huge snow storm a couple days ago and I again got 14mpg. Funny how that happens.

Really, I would have thought the manuals would rev lower. I edited my post to include i had a manual tranny.

I figured you had a manual based on your revs. We have different diffs though because of AWD and RWD so mine revs slightly higher.
