Real-World Gas Mileage With a New Toyota Highlander

It’s official. Our Highlander averaged 18.5 mpg on its first tank of gas. This involved ca. 300 miles of mixed city/highway driving, including a fair bit of stop-and-go traffic, some country roads, and a smidgen on the freeway.

I’ll be updating periodically, but one interesting experiment is that I have coming up this weekend is a roughly 2 hour (each way) interstate trip that should give me a sense for mileage at the top end.

Update: The results are in. Check out our highway mileage.

Of course, this was still within the engine break-in period, so things may change. If anything, I’m hoping that the mpg will improve a bit over time.

Oh, and for context, we have a FWD XLE with an EPA rating of 19 mpg in the city and 25 mpg on the highway, and 21 mpg in combined driving.

      Probably should adjust the air pressure for the additional load, will help mpg as well
