As previously reported, our new Toyota Highlander averaged 18.5 mpg in mixed city & highway driving on its first full tank of gas. Yesterday, I had a chance to test it out on the interstate, and it did pretty well.
It was early on a Saturday morning, so the roads were clear and I was able to cruise at a consistent 70-75 mph. Yes, we’ve moved beyond the engine break-in period, so I’m free to just dial it in and go.
Anyway, I reset the mileage meter just before pulling onto the interstate and saw an average of 24.5 mpg vs. an EPA rating of 25 mpg on the highway. It was a smooth ride, and I was quite pleased with the mileage overall.
