You know, I just had to throw in a comment here about mileage after reading
a couple of posts saying 2003-4 2.7L V6's getting over 30 mpg hwy.

Those folks who are doing over 30mpg with this engine are either not
calculating their mileage properly, or are driving 50mph over FLAT
INTERSTATE w/cruise control and NO A/C running AND not stopping for any
reason for 300 miles straight.

The best I've EVER gotten with my 2004 V6 Sonata GLS was 27.5----and that
was with "normal" interstate driving of 65-75mph-with A/C running with rest
stops ever 100 miles or so-----

Yeah, that sounds about right. When my GF drives my Sonata on the
highway she gets about 27 MPG. When I drive it on the highway I get
about 24-25 MPG (I drive between 70-80 MPH and pass occasionally, she
between 65-75 MPH). Her city mileage is about 22 MPG, mine is more
like 18-19 MPH.
 
I think a fifth gear or lower gearing on the overdrive would probably help
out a lot----2600 RPM @ 70 mph is too much-----a fifth gear, like my
Explorer, would prolly bring it down to around 2200 or so, and improve
mileage----

yep. I get 17-18 mpg city, LOW 20's highway. (2004 2.7l V6 with only
1800 miles on the odometer). Hope it gets a little better after it's
fully broken in. My big Ford Explorer (4 liter V6)gets almost the same MPG.

Wrong, I went 75 miles per hour on average, with rest stops, with AC
on and got well over 30 MPG. Sure, it was mostly flat, and I did use
the cruise. This even takes into account a 30 mile stretch of
construction where the traffic was stop and go. I probably averaged 55
to 70 MPH in that stretch.

According to http://www.fueleconomy.gov/feg/driveHabits.shtml, driving at 75
mph vs 60 mph makes a difference of about 5 mpg. It looks like driving just
a few mph slower than you are now should make up the discrepancy you're
seeing.

You're not just talking about a "few" miles per hour, you're talking
about 15 miles per hour. On the stretch of I-94 I was driving, I would
have been blown off the road as most drivers were going 80 to 85 MPH.
That's the stretch from metro Detroit, west, across the state.

According to the site, every 5mph is like paying $.10 extra per gallon. At
$.10 per gallon extra, that would be about a 5% drop in fuel economy per
5mph. You'd be talking 3-5 mpg on most cars for a 15 mph difference in
speed.

I also don't know when these figures were last revised. In my 1979
Fairmont, that was about right. But in my 1990/1002 Tauruses, there's no
noticeable mpg change between 55, 65, and 80 mph. I think new
transmission technologies and more aerodynamic cars play a large role in
this fuel economy at higher speeds.

This makes no sense to me at all. My father in law has a motor home
that only gets 10 MPG. That's with him going 55 MPH. You're trying to
say if he went 15 MPH faster, his mileage would drop 15%? to 8.5 MPG?
I'm not even sure how you can say " You'd be talking 3-5 mpg on most
cars for a 15 mph difference" It all depends on how many MPG a car
gets.

Agreed. The kooky way the federal government related the difference is
already a big part of the problem. I was simply trying to put out a
general range based on their info that would cover the most common
passenger vehicles. To say an additional $.10 per gallon introduces more
error into this calculation than is already there because now it has to
change based on current gas prices. This computation method is really
ridiculous, if you ask me.
