I just picked up my all wheel
I just picked up my all wheel drive hybrid sienna at Thanksgiving. Running the heater, I am getting 22 to 27 miles per gallon on the highway, in an area with rolling hills and strong winds. The only time I get above 30 miles a gallon is I if there is no wind, or the wind is behind me, or I am going downhill. I am extremely disappointed in the gas mileage, and wonder if there is something wrong with my car, because it appears to be an outlier with low gas mileage. . I have it an Eco mode, and I drive like a granny.
