AWD or FWD? Your numbers are not terribly out of line for AWD.Did a long(ish) road trip (234 miles, up into the mountains) this past weekend. I dumped a bottle of Techron injector cleaner in the tank and filled up. All highway driving pushed me to to an all-time high of 20.99 mpg. My normal in-town driving is around 13-14 mpg. I gotta figure out what is causing my high fuel usage. I feel like I should be getting 4-5 mph higher for all types of driving. I lost the lead foot of my youth.
I can. I just didn't think to hook up the reader until I was already on the way and totally forgot for the ride home.Hey BillG
We both have 06 LEs. I think you should be getting at least 24mpg at highway speeds 65-70 mph. Are you able to see your fuel trims while driving?

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.
I have the same issues with a 2004 Sienna LE IT runs smoothly no engine roughness great pick up. Any help would be appreciatedI have a 2008 LE, 85K miles on it. I just bought it, runs great. But I put a full tank of gas in, and used the gas till the gas light came on, and my reading was 241 miles for that tank of gas. With a 20 gal tank, that comes out to 12.1 miles per gallon.... Anybody care to enlighten me? No CEL lights on, OBD reads everything in the green. Starts right up, runs quiet, doesn't burn oil.. Any suggestions on how I can increase my mileage?
I'm a couple years after.... an 08 AWD, and I get around that on the highway. More like 14-15 in city driving.What's the best folks are getting for an '04-'06 AWD? I'm averaging around 18 MPG cruising at 70 on the highway and wondering if there's anything I can do to improve efficiency.
