05 LE, package #8. It has 35K on it right now and new Yokohama Avid TRZ's (very sweet tires). We just got back from a week long trip to Cooperstown, NY from Columbus, Ohio. Total milage from driveway to driveway, 1367.2. Total fuel used, 53.872 gallons. Total MPG for the trip, 25.38mpg. Fully loaded both ways, family of 4, lots of luggage, I removed one of the middle captain chairs, I usually do for trips. I also removed my luggage rack cross bars a while ago, as they are never used. My tires always stay at 41 lbs. For the trip there, I went from 57 to 64 mph most of the way, there was a spell when I was going around 72-74 for about 40 miles. While in Cooperstown for the week, I averaged 21 mpg. The most impressive part of the trip was the return. I gassed up just after I got on I-90 and went 495.5 miles on 17.36 gallons = 28.54 mpg. On this part of the trip I was on CC at 63 mph for 90% of the time. Some things I noticed about going a bit slower than I normally have in the past, you will see many of the same vehicles pass you more than a couple times in a big hurry. I was not nearly as fatigued as I was relaxed watching cars pass me all the way instead of hurrying and always trying to find the open lane to keep moving at speed to my destination. Also, you never have to constantly look ahead for cops taking radar. I rather like going between 60 and 65, it still gets you there in good time and these Sienna's just love that speed for efficiency. I'm sure I could get over 30 mpg going a steady 55, but that is just anti-social and kind of dangerous as well. I forgot to add, that AC was used for about half of the trip. AC was used every day while in Cooperstown, city driving and most of the second half of the drive back to Columbus. All in all, I'm very impressed with Sienna's performance. It delivers a quiet ride , lots of room for "stuff", entertainment for the kids, (never heard a peep out of them, well except for the laughter while watching movies), just a very balanced vehicle and I'm glad this one is mine.

| hi new to the forum. Our trip computer consistently shows about 2 mpg above what the actual mileage really is by doing the math. Speedo is GPS verified as accurate for both speed and distance. The trip computer seems to be "programmed"to always show the "optimistic" old EPA numbers. Anyone else have the same problem? Thanks | |

Replying to: dnbqee (Jul 15, 2008 10:10 am) Just FYI. Loaned the van to my lead-footed brother and he "discovered" the 266hp V6.  23.3 mpg.

We just bought the car this last saturday. We are getting, based on the mileage display in the car, 22mpg in 50/50 mixed driving. How close is the display to actual mileage anyways? I should probably try the search feature...

Replying to: dwarfl0rd (Aug 11, 2008 7:03 am) Just got 24.9 mpg in mine doing about 50/50 city highway. So far this tank it says 25.6mpg from mostly highway, but I was stuck on the Chesapeake Bay Bridge last night in that traffic since that tractor trailer drove in to the water (wild).

My family and I just returned to San Jose, CA from visiting family in Arizona in our new 2008 Sienna LE. I took along our new Garmin Streetpilot C580 to help us along our way. One finding was that the odometer read 4.5% less than the GPS. This was confirmed in two ways. First it was noticed that in the "next turn" estimates that the turn would come up sooner that I expected looking at the odometer so I started marking the odometer readings with the next turn at 100 or 150 miles. This method indicated that the odometer read 95.6% of the GPS distance Later I discovered the trip meter function on the GPS and reset it and one trip odometer for the leg home. Over a GPS indicated distance of 1075.4 miles, the odometer read 1025.1, or 95.4% of the GPS. Because of this disparity I have three estimates of the MPG. Odometer: 24.7 GPS: 25.9 Trip computer: 25.3 This is 2056 miles of driving on a van that only had 330 miles at the start of the trip. It is about 90% highway and 2 or 3% unpaved roads. Most of the time we were running 75 MPH through 100+oF desert (as high as 112o at one point) with the A/C running full blast. For a vehicle with this much weight and power I am impressed by even the lowest MPG estimate. The A/C can make the whole van cold in those conditions while the engine barely notices and still has a lot of passing power even while going up a 5.5% grade. And before anyone asks what I was doing in Arizona in August... my dad has an in-hold in the middle of the national forest in the Dragoon mountains (1.5 hrs southeast of Tucson) and it is not nearly as hot as Phoenix or Tucson. July and August are the monsoon season there and just as the day is getting to it's hottest point the rains roll through and cool the place down. We had thunderstorms most days we were there. Very nice.
