I have an 02 L.L. Bean, which of course has the H6, and I am wondering if getting 300 miles to a tank, or 20mpg, is acceptable for these cars. I live in a pretty suburban area, and while it isn't city driving, there is stoping and going as well. I was hoping for more along the lines of 24mpg. I have been using mostly regular to get these numbers, and now I am in the process of seeing if premium helps. I used fuel system cleaner and ran a cleaner through the engine, and the alignment was checked. The crossbars are on and my tire pressure is at the door recommended pressure. I am thinking maybe I was just spoiled in my little ol Loyale with the 1.8 EA-82 H4, I could get 30MPG all day.
