These days I'm doing a bit of highway driving 100-200 miles round trip. With just me in the van I am seeing 25-26mpg at 65-70 mph. My 06 LE has 171k miles. I'm happy with those numbers and I am running premium gasoline

Have you ever done any mileage comparisons between using regular or premium?

With 140k miles on it, my 2007 van is getting the best mileage in its life. When new, it would top out at 25 mpg on highway no matter what fuel grade I used. For the last year or two, I've been getting a good 27 to 28 mpg on the highway using 87 octane fuel. All mpg measurements are hand calculated per tank.

Several years ago I had a 2004 Sienna LE van with 254,000 miles on it. We use to take trips to Florida in that van. After filling up with Sunoco premium, I drove that van from Longwood Florida, 570 miles, to Granite Falls North Carolina on one tank of fuel! What a great vehicle that was!
