I don't know what to make of this at all. I don't pay attention to the MPG on the DIC but i reset it with fuel used. It said 12.6 gal used when I filled up today and the pump clicked exactly at 12.6. The last couple times I've been able to squeeze a lot more fuel after the click. This is the third straight time my light came on at exactly 12.6 gal, which makes me think the tank is 12.6 gal for all models with 3 gal of "reserve." I don't understand if it draws fuel from the reserve though...?

of course, you have to actually use the 1 click method to accurately compare. I for one just try to haul as much fuel in there as possible

Interestingly though, my best tank on fuelly hand calculated was 37.2 MPG on a road trip. The DIC told me 36.5 MPG. I literally went gas station to highway to cruise control to gas station. Maybe the DIC screws up when you accelerate?

And the whole reserve thing throws me off. 12.6 on the DIC and my pump cuts off EXACTLY at 12.6 every time. Light comes on at 12.6 every time. This is supposed to be 15.6 wth! I'm somehow able to squeeze an extra gal til I see the fuel coming up and personally I'd rather squeeze in as much as possible since I hate frequent fuel stops/
