2007 Sienna Limited AWD
We get 17 city and 20 on highway.
Brand new we were getting 19 city and 22 highway, about 3 years ago we were getting 14 city 16-17 highway. I replaced the plugs, 3 rear coils, changed differential oil, transfer case oil, transmission fluid and coolant and it got better. It can probably improve if we change our driving habits .Azul yours is a 3.5L engine. 04-06 had the 3.3L engine. Getting 17 mpg around town is not bad at all.
