My 2005 AWD gets no better than 18 MPG by mleonardo

I bought my van new in 2005 and have gotten no better than 18 MPG HWY. I have used 92 octane and 87 octane. There is no difference. This van has very little power compared to my 1997 GMC Yukon with a 5.7 liter V8 and gets only 2 to 3 MPG better. I like the vans power sliding doors and the AWD is great in the snow and ice but with the new V8s getting close to 20 MPG, I kind of wish I had bought a new Yukon instead. My van is paid off and I plan on keeping it five or six more years but I will be replacing it with a V8 powered vehicle. There is very little difference in fuel mileage but the V8 has a lot more power.

If you want power, the newer Sienna with the 3.5L gets better gas mileage with AWD and has more power than a Yukon and the older Sienna. We drove an 07 XLE and an 07 LE, both were very quick and felt as fast as the newer Escalade my relatives have(has 6.2L). Test one out, you won't be depressed
 
By the way our 04 Limited AWD gets 16mpg in town and 20-21mpg highway.
 
The new 07 LE FWD we had for a couple of days got 21-22 mpg in city driving and up to 27mpg on the highway!

Thanks for the reply. After spending close to 40 grand on my 05, Im not in the market for an 07 or a yukon for that matter. What you say is interesting though. I was thinking about this. By the time I get rid of my sienna, my kids will be close to 12 years old. I think I will probably get a crew cab pick up instead. But it won't be a tundra.
 
I really wish my van got the kind of mileage that you got with that 07. My window sticker stated 20-23 or something like that.

You don't like the Tundra's?
 
My uncle has had his 07 Limited Double Cab 4X2 in Nautical Blue(5.7L V8) for 6 months and now has about 9,000 miles on it. He loves it and it averages 17 mpg.
No problems at all.

We have a 2005 LE purchased new in July of 05. For the first 3 months, I was very careful about how we drove it and I took great pains to accurately compute the mpg. It was so close to the on board computer, I stopped doing it manually. During that first 3 month period, it got 22/23 city and 27/28 highway pretty consistently. I have never reset the mpg computer on board and it now reads 22.1 with 49k miles. We do a LOT of city driving and when we drive on the highway, we are in the fast lane doing 70-75mph. If the 3.5l gets as good or better, thats great, I'm pretty happy with the 3.3l.

Around town we've been getting around 22mpg, but I finally took a road trip and saw 27+ again.

Gross weight and MPG by vinijin
May 14, 2008 (2:31 pm)

I am wondering if there will be any difference of MPG between base model CE as compared to fully loaded Limited. All wheel drive, 17" aluminum wheels, Power sliding doors, power hatchback, and other accessories all add weight to the vehicle. I checked edmunds.com and it lists gross weight of 5690 lb for all the models. But I guess gross wt will be different between these models (and accessories) and will eventually impact MPG.
 
RAV4 uses same engine (3.5 L) but rated 19/27. The gross weight of RAV4 is 4720 lbs. I am ready to buy new Sienna and trying to figure out how to keep Gross weight minimum. Most importantly, will there be any impact of this low weight on MPG ?

1999 XLE mpg = class action suit. by Luzer
May 14, 2008 (3:56 pm)

Around 17 - 18 city
20 - 22 Hwy at 70 - 85 miles per hour.
 
WARNING - These numbers are a little off as my GPS reads about 2 to 3 mph less at 75. (GPS = 73 and Van says 75; GPS says 77 and van is at 80) This translate into about 2.6%to 3% less. So the numbers are about 0.5 mpg too many, best case.
 
My Garmin 650 GPS and my Pontiac Vibe are dead on.
Wheels are original wheels with the XLE.
 
Can anyone share GPS mph experience?
A few post before notes a slight diff.
 
This also affects odometer reading for selling the van, or your lease values....100K miles is really closer to 97,000 miles.....
 
This was not the intent when I started writing this post, but can anyone say "class action suit?"

2007 LE FWD, package 3.
 
Basically a mid-level model.
 
The Limited are heavier, and I have seen a tendency for the lighter models (CE, LE) to get better gas mileage.
 
This is purely empirical data. EPA says they're the same.
