Hybrid true fuel tank capacity?

[thosw]

Oddly, the large Owner’s Manual states 13.8 gallons and the small Quick Reference Guide (which also came with my vehicle) states 14.3 gallons. Both manuals have a July 2021 published date on the back covers. Can anyone confirm which is correct?

I had not noticed that. Perhaps that explains the discrepancy.

I’m looking at the manual online right now and it says the hybrid capacity is 13.8 gal.

???

So, there's actually a bunch of equipment in the gas tank of the hybrid, more than usual. It's in place to improve gas mileage. At least part of its function is to pressurize the tank. The problem is its eats up space.

As I recall, the actual tank size is in the 14 - 15 gallon range, but that equipment takes up space and it can't be totally submerged in fuel so the actual capacity is 13.8. This is why hybrid documentation is very insistent that you don't try to do a double fuel up to 'top off' the tank. Once the overflow trips the gas pumps auto-shut-off, stop.

EDIT: Oh, and 13.8 is correct as far as capacity goes. I ran this thing dry for my first fill-up and I only got 13.775 gallons in.

When the fuel gauge shows empty you generally have 10-30 miles of reserve gas remaining to get to a gas station safely. Objectively, you should never let you vehicle get that low to find out..

My Impala had 3 gallons (60 miles) of fuel left after it hit empty. I don't think that was reserve though, pretty sure the gas gauge was just busted.

At 20 dte, I only got 13.086g to fill it up and give me 526 dte.

Math on the mileage was 36.6 on the dash, 37.7 on the actual pumped fuel. So, either it clicked early or my Guage is a little conservative on calculating the mpg.

Just filled up for the first time with 4 miles till empty. 14.6 gallons. 420 miles so 28.8 mpg vs computer saying 33mpg. Something seems off..I’m guessing it was the pump I used.

I'm guessing it wasn't entirely full previously. Easier to keep track when you are the one pumping it the same way every time.

I just filled up my hybrid for the first time (560 miles) and put in 14.78 gallons. The gauge said I had an eighth of a tank left and I didn't overfill as per instructions. Somethings odd.

How do you know you "ran it dry" without actually running OUT of gas? Did you? (I wouldn't suggest it.)

I’ve done a complete fill up twice with about 40 miles to empty both times. First time I got the world’s slowest pump and ended up with 14.3 gallons. Today I had a normally functioning pump and put in about 13.4 gallons. So who really knows?
