Maybe its my old age but my 07 ES 350 seems to be getting less mileage after two years than a year ago. It is still respectable. Maybe its the winter fuel formula or a dirty air cleaner but it has 24K miles on it. Onn a trip with three in the car it gets around 27 mpg at 70. Around town it is 20 mpg. Last year in similar driving it got 22/29 respectively. So it dropped about 2 mpg. Has anyone else experienced the same results?

 

We just returned from a trip to FL and were getting 30-32 mpg at 70-80 mph with two people and a full trunk. Most of it was closer to the 30 than the 32. This was per the cars computer. When I've checked it manually, it's usually about 1 mpg less than the computer.

 

When comparing current gas mileage with previous you should keep in mind the increasing use of alcohol in new gas. Alcohol blends will deliver poorer mileage than straight gasoline.
