I had a 2007 Titan with the 5.6 and had to fuel up every 4 days commuting. Now I can go 2 full weeks without fueling if I don’t drive anywhere over the weekend. I have tons of pictures on my phone of my mileage. My best 50 mile avg was 36.something. If anyone wants to see any pics of the range and mileage pm me your phone number and I will send them to you. It’s no BS. My commute is pretty flat with some small hills on the way.
