I was low on fuel the other day and started wondering if I ran out of gas, would the truck go into all EV? If so, would it be restricted to something like a limp home mode? I searched through the owners manual but couldn't find anything.

Hilarious posts aside, the battery is not big enough to give you very much range. Also, depending on the battery technology, it can be harmful to run a battery completely dead. I know my Sonata Hybrid warns me when the fuel gets too low that if I don't stop for fuel I could permanently damage the battery - of course that was written by lawyers.

In general it is bad to run a car dry. It kills fuel pumps that are cooled by being submerged in the fuel tank, so I wouldn't try it.

But classic Seinfeld is way funnier than my boring reply.

The battery management system would not allow you to run it below the Ford-prescribed safety factor, and the 15 miles of standard battery-only range would often be enough to limp you to a gas station. As a Powerboost and Tesla MX owner, I've seen lots of Tesla videos and discussions on Tesla forums about what happens when you run the battery low on EV's (and have done it a couple times myself, had to be flatbedded once in the Black Hills) - so who's gonna take one for the forum team and try it? My money is on the battery-only system running until the battery safety reserve is hit.

I’m still waiting for my Powerboost, but when I got my 2015 3.5 EcoBoost(my 1st vehicle w DTEmpty) I put a can of gas in the back when it got low. When it reached 0 to empty I checked the odometer and kept driving. 40 miles later I got bored of driving and went to a gas station and filled up 37 gallons in a 36 gallon tank.
Tried the same in my 2020 Escape Hybrid ( not plug in). 37 miles later display said “safely pull over”, which I did. I don’t think it went 500 feet on the battery.
