My 2017 Highlander V6 elx awd and I just made a 17 hour (two days) trip from Pennsylvania to Florida. I reset the fuel consumption monitor at the very start of the trip and used the cruise control on the almost exclusive interstate trip. At the end of the trip the fuel consumption showed 22.5 mpg! Is this what I should expect or is something amiss? I purchased the vehicle in June with 22,400 miles. It now has 34,000 on it. I had expected to get around 26 or 27 mpg on interstate driving.
