TESTED & CONFIRMED*

HYBRIDS HAVE 16.5 Gallon Gas Tanks

Hybrid Mavericks have 16.5 gallon gas tanks, but you are not supposed to run them dry. I did, once, to get the correct information confirmed.

The computer uses 13.8 gallons for computing your range. 13.8 is the safe limit of fuel you can use EVERY TIME without fear of running out.

13.8 is the maximum you should use between refueling, but 13.8 does NOT equal empty.

You should feel confident taking it down to MTE=0 if you want.

I drove until I couldn't.

No spittering or sputtering, it just quit. Ding and "Stop Safely Now".
It allows EV driving for as long as the HV battery lasts. The range will be based on state of charge of course. You're likely to have at least one-third of a mile, probably 1 mile, at most 2 miles of EV range. The slower you go, the farther you will go. So unless the station is in sight, milk that puppy!

Gas station I used is a new one. Just installed. Just opened for business a few weeks ago. New tanks. New pumps. New nozzles. Recent calibration.

On automatic, pump pumped in 15.823 gallons until first click. 15.823 without any "topping off".

I let it rest a few seconds, then squeezed the trigger 3 more times with short rests between clicks. (Three more clicks)
Total dispensed: 16.645 gallons.

The PSA (Public Service Announcement) is this:

When people believed the tank size was 13.8 gallons, they would hesitate to use more than 11.8 (approximate) per tank, wanting to keep 2 gallons of reserve for various reasons.

At least 2 gallons exists up & beyond the 13.8, therefore drivers need not "conserve" or "reserve" any extra fuel and can drive right up to MTE 0 on a regular basis, and a little beyond, when absolutely necessary.

While I went additional "clicks" for measurement purposes this time, this is not recommended in the owner's manuals. While one or two additional clicks is generally regarded as safe to weed out premature shut-offs on overly sensitive pumps, each owner does so at his/her own risk of spills or equipment damage.

*I'm just going to say at least this much is true. There are some reports of persons adding 17+ gallons to a hybrid tank.

That is some dedication. Thanks for the info. I don't have a hybrid, but makes me feel better that Ford likely underestimates the remaining range on the EBs as well.

I've read posts of people adding 17.5 gallons to an EcoBoost. At least one person added 18.0 gallons.

Someone made a similar post back in the spring or early summer, they ran it right out of gas and limped to a station on electric power.

All vehicles have larger tanks, as in they leave a reserve that's usually good for 50 miles or so beyond empty. Usually as a vehicle ages sediment and condensation builds up in the tank and can be found at the bottom. Not a big deal to dip into that when the truck is new, but wouldn't want to do it too often as it ages, unless you burn through all of it on a regular basis.

I'm not saying this to be a know it all, but the fuel is siphoned (picked up) from the bottom of the tank all the time. There is no "space" for the sedimentation you described. Maybe very old cars were like that???

The sediment floats in the tank, not settling. As the level drops, so does it. The lower it goes the greater the chance of clogging the fuel filter. Fully admit I didn't word that well at all.

You are correct. But more important, on my other cars, and most vehicles, the fuel pump is cooled with flow of fuel thru the fuel pump. Some vehicles can have their fuel pumps quickly damaged by that heat with no fuel. Even says it in the owners manual.

The Maverick fuel pump is in a sump in the lowest part of the tank.
1 gallon (guess) should be sufficient to keep it submerged. Granted I ran mine empty (or did I? Maybe not?) but it's winter. Maybe I didn't run it "empty"? Maybe some sensor triggered when I hit some low limit? It was a controlled stop, no different than any other transition to EV mode.
No shudder / stutter like I was expecting.

Maybe it "shut off" rather than harm itself by actually running dry???
Also I noted no air in the lines or anything upon restarting. Was smooth as ever.
Speculation.

I wish tanks had a little drain or port on the bottom to drain the moisture/ gunk periodically.

Cld this explain why many hybrid owners get higher MPGs than ford states bc they run down the gas further?

That's higher miles per tank, yes. But not a reason for higher miles per gallon.

If you want to remove moisture, add some high proof alcohol.
Wait. Most stations already do.
Never-mind. Moisture should never be an issue. Driving through a hurricane excepted. 😎

Wow, 2.7 gallons available past zero DTE, that’s an easy 100 miles - that’s crazy!
