Dealer has checked it twice, and they claim all is normal. I don't use this as a family van. This is my work vehicle. I do carry equipment around: 275 lbs. all the time. (Weighed at local propane dealer day of purchase, and 3 days later after vehicle was loaded.) This weight is equivalent to 2 adult passangers. I find this mileage unacceptable. Have owned Jeep Grand Cherokees, Chrysler Town & Countrys, etc. with the same load, and always got 17+ mpg. Spoke with a neighbor who traded in a BMW X5 that he filled up twice a week with premium fuel. He now fills up his exact Sienna as mine, 3 times a week w/regular unleaded, yet it is costing him more per week in fuel costs than in his previous BMW. The reason I bought this van was because of it's AWD. Next problem is the run flats, which I have been advised will last maybe 12-15K before they need to be replaced. NEVER NEVER NEVER will I own a Toyota again.
Run Flat tires is a NO NO. They are no great thing. Running one tire flat for 50 miles @50MPH( as recommended when yu encounter a flat) will destroy the tire to begin with. They have poor traction and high rolling resistance/drag And all Sienna 4WD's are historiclly pigs on Fuel. Has always been that way. Run flat tires are not as serviceable like regular tires are.
Yes Runflats are notorious for wearing out rather fast. And are expensive to replace. Usually special order.

BTW, E85 [I]increases[/I] fuel consumption. This is well documented.
Yu were better off getting a FWD Sienna. Yu just picked the wrong model Toyota. There are many other better Toyotas for MPG. The 4WD Sienna was the worst pick. I know several people who own them. And, they got rid of the Run Flat tires!
