Miles to Empty

[New recaros]

Yeah I used to hear that sort of thing from time to time, back in the day. I’ve never heard it in recent higher-tech times, however, and I’ve never experienced anything like that in any of my vehicles, including the Raptor.
I’m curious if you have any real technical backing for this, or is it just a habit you have?
For me, I wanna “use what I bought,” i.e. I have a 36 gallon tank and I’d like to be able to comfortably use most of it…

There very much is technical backing to keep you tank full.
When you use the fuel from the tank, air replaces it. What does air have? Water vapor. When you cool the water vapor, It condenses into water. Water in the fuel is no good for anything. I try to keep my tank half full to reduce the chances of water in the fuel and prolongs the life of filters, injectors etc…
