So in light of a few threads of Sienna owners talking about poor mileage, I'm curious as to what kind of Mileage your Sienna gets. Also, it'd be nice to specify the year and mileage (odo) on your Sienna.

So Let me start off, I have a 2000 Sienna with 104k miles, and I get 18-19 mpg with mixed driving (probably 60/40 Freeway/City)

'01 Sienna, 27 hwy, 22 around town, mileage 264,000. Goal: 300,000

17-19 MPG, since day 1 in a 2000 with California emissions.

Some post much higher mileage, others are similar to mine, a few are worse. Only difference I can account for is the emissions standards, so please also post what yours is.

Ours is a 2000 with Cal emissions. (I think that most Siennas have this system)

It's got 237K miles on the clock. We've never averaged better than 19MPG consistently. This summer we've been getting 17MPG on a good tank.

Always get about 12 L/100km = 20 MPG US. Mixture of city/hwy. Got 150,000 km (93,000 miles) on my 2002.

'98 Sienna with 297,184 miles and Federal emissions.

Mileage is consistently 17 mpg around town. On this summer's trip to the beach we never got less than 22 mpg, and on two legs of the trip we got 24.

This is my wife's daily driver, and she spanks it hard. Makes me wonder how she's gonna treat ME when I get old and high mileage!

I can't believe you're about to roll 300K. That's exciting.

I'm working on mine today. I hope to find some MPGs but I doubt that I will. I'm changing the oil, the trans fluid, and cleaning the throttle body with some CRC. Maybe the throttle body cleaning will help but I doubt it. We'll see. I've never cleaned it before. The van's at 237K now.

Gas mileage tips: Front tires 38 psi, rears 36. Synthetic oil in engine and transmission. Air filter new. All four rear captains chairs removed (240 lbs) and factory running boards (130 lbs). I could remove the chairs because for my job I haul boxes of stuff occasionally and our kids are grown. Horizontal roof rack bars removed. Best mileage will come in cool weather where the A/C is not being used, cruise at 65. That is all I can remember.
