Mine is a 3,3. It is 273 miles from my house to Valdosta Ga. Twice we have filled up within a mile of home and driven straight to Valdosta, Both times on ECO and at 72mph average using cruise. It took 8.81 and 8.80 gallons to fill it when we arrived, both times. That is 273/8.80 = 31.02 mpg. So if you drive 400 miles at 31 mpg then 400 miles is easy as it takes 12.9 gallons which leaves you plenty of gas in the tank.
This past week was a pretty normal week, drove 345 miles, used 14.02 gallons of 93. That is 24.6 mpg. This was mainly in town, one 85 mile interstate trip in there. That is using Smart Mode with cruise anytime I can. So I think mileage is good. I do not use the car computer to figure it, although it is very close most fill-ups. I try to only use Shell 93 but have had to buy other brands a few times but then only one such as Exon or Mobil. I, as I have said before, worked in the manuf of fuel awhile ago and I do not use cheap no name fuel, many of you do, that OK as it is your car. But for me, name brands Premium only.
You may be getting great mileage for those two times, but it all depends on traffic conditions, the lack thereof, weather, and road conditions. On flat roads with little to no traffic, and no wind against you, only freeway miles - you certainly could get 400 miles. But even so, I sincerely doubt you or anyone here will ever REALISTICALLY drive 400 miles in one tank, as there is too much variability in road conditions. I would hardly say it's "easy." Also, I always fill up with Shell premium as well, though I've tracked absolutely no difference in my mileage when I used Chevron a few times.
I've gotten even better mileage than you (35mpg) but such was only on a flat freeway, driving in ECO with no stopping related to traffic, weather was nice as well, and I wasn't going very fast at all. No way those conditions would stay for a full 400 miles. I have a 3.3 AWD, btw.
You seem to be really intent on proving superiority to the rest of us, so let's see some proof of a 400 mile tank during regular driving. I don't doubt you can do it, nor do I doubt anyone here can do the same - but such would be only under carefully selected conditions. No way you can do it with mixed city/hwy driving with varying weather conditions. My argument is that you'll only get that kind of mileage when everything is near perfect - which is extremely rare.
