Question Gallons to Fill a Tank

The 2012 Hyundai Sonata Hybrid is rated to have a 17.2 gallon gas tank. Every time I go to fill up on my gas tank (after the Car is on E), I can only fill 14 Gallons of gas. Does anyone else have this same problem? Where are the other 3 gallons?

Any advice would be appreciated.

What I've found in my car is that there's at least two gallons left in the tank when my Distance To Empty (DTE) indicates ---. The DTE shows three hash marks like that once it drops below 30 miles to empty. On one occasion I drove 80 miles past that --- point before filling and it still only took 16.9 gallons.

So to answer your question the other 3 gallons are still in your tank, kind of like a reserve when your gauge first hits empty - or when DTE indicates 60 miles.

People who actually USE all 17.2 gallons before filling up find it REALLY inconvenient......because it seldom stops running right beside a gas station.

Hahaa, ya know.. Ive been getting just oer 15 gallons on my fillups with a tiny bit of forcefeeding up to the next dollar or fitycent mark, have full pips and its always good to have a reserve just in case.

If I may interject in this conversation...I highly recommend that you NEVER allow the fuel to get to empty! The problem arises when the fuel gets that low the chance of the fuel pump running dry becomes greater. The fuel as it passes through the pump acts as coolant and cools the pump. Take a look at how much a new fuel pump costs plus what it takes to replace it and you also will never let the fuel level drop below 1/4 tank as I do. Consistently running low on fuel is one of the top three reasons for pump failure.

Agreed its good to keep the FP cooled, the fuel flowing thru it also helps accomplish this, would always recommend running tank as low as possible to prevent build up of bad fuel or water since those sediments normally sink. Fuel system repairs ie: clogged injectors, flushing out bad fuel, pump filter replacement would be much more costly.

Yep.....right to the bottom.....where the fuel pickup is located.

You don't have to do anything special to ensure that no harmful liquids "accumulate" at the bottom. There's a LOT of sloshing around during normal driving too.
