701 miles on 13.51 gallons.  Way too close to ever try it again.  Carried around some gas in the trunk just in case. Had to use the A/C sometimes.  700 mile tank.JPG   74.87KB   0 downloads

When Miles to empty reaches 0 you should be able to go another 25 miles. BTW I tested the FFH tank and it holds 14.1 gal., how many gal. did it take to fill up your car?  Good job!

Yeah it was about 668 when it went to 0.  Squeezed in 13.6.

So you went 33 miles passed 0 to E, Now that I think about it I may have gone 60-80 miles passed 0 to E. I thought the FFH would never run out of gas.   At the end I was using a 4 mile loop so I was never to far from the Station where I wanted to fill up. I did try to keep HVB charged up so I would have good range in EV.  When it finally did I was about 2 miles from Gas Station, but was able to EV all the way there.

ptjones So you actually drained it?  Is that when you got 902 miles?  Isn't it bad for the injectors to drain the tank down to nothing in any car? That's what I've always heard, but not just when empty but for the little bits of debris that could be in the bottom of the tank.  I won't be doing this again (unless I am managing 60miles per gallon) but the best I've ever gotten is 53mpg but never could get over that.  I'm taking it easy right now and the dash is reading 54 and since I am mostly aclimatized to the summer I don't need ac, maybe I can continue that for a personal best.

Here is a thread I started back in Jan. 2014 on fuel tank capacity: http://fordfusionhyb...1gal-fuel-tank/  and as far as harming the fuel injectors from running out of  gas, I ran out of gas 6 times in my CMAX in the first couple of years I had my car and now I have 161k mi. and I'm getting the best MPG's ever.  BTW when you run out of gas there is still gas in the tank and there is also a fuel filter to protect the fuel system.

610.9 miles. Readout indicated 55.2. Actual 53.3. Very happy!

I literally mean run out of gas as in ICE won't run nor start.  I once ran out of gas in my other Ford just to see how far it would go before empty and it took a while to get it started again after putting a couple gallons in it.  Conventional wisdom back then said that having air sent through the injectors could hurt them or the fuel pump but perhaps on the newer systems they do something to compensate for that. Also, having a clogged fuel filter is a problem too.  Changing those out is a messy pain in the arse.  I know, I've done it.

As soon as the fuel system losses pressure the ICE stops, there is still fuel in the lines so after putting fuel in the tank the ICE will immediately start. I currently have 175k miles on My CMAX.   BTW the fuel filter never needs changing.
