gallons to fill an empty tank

FAQ. Also, page 206 of the 2005 Owner's Manual.

 

There is no needle and there is no E

SOrry, was kinda of funny

This will depend as the tank is like a bladder which expands and contracts depending on the temperature and other factors. One time you will fit 11.3 gallons, next time you will fit 9.6 gallons, next time you will put 10.7 gallons, next time you will put 8.9 gallons Have fun figuring out how much you will put next time.

 

With my car if I wait for the flashing bar, I can generally put in just over a full 10 gallons.

If I get it really low, almost dry, but still running, I have put in 12.4 gallons.

If temperatures are under 10 degrees, I might not get the full 10 gallons in.

If I fill just to the click off, my fill ups at the flashing bar would be typically 6 to 8 gallons.

But each car is different slightly.

 

It hasn't been really cold on the days I've filled up lately, but I've been short of a full tank for some reason.

I'm nearly 100 miles into a tank averaging over 44MPG, but I've lost the first bar on the gauge already. Normally, if full, I'd expect 160+ miles to do that.

I guess when I see gas about to splash out at me, I'm not supposed to give up...

well, it's about 38 degrees here. I am averaging 54mpg but I also lost my first bar at 100 miles. Just tell you how different each car is or how much external factors can affect the accuracy.

 

I think you didn't understand my answer.

I can fill up to 11.9+ gallons on my E tank. It varies by the bladder, and how close I want to run it.

 

<_< Well.... FIRST, you'd have to empty the tank... I have found the technical 11.9 gallon capacity to be a "specification" somewhat unrelated to the practical day-to-day operating conditions.

How many miles per tank depends largely on your driving habits and specific conditions - terrain - percentage of freeway to short trips - how you accellerate from a stop - how many cold starts per 100 miles, etc. The fuel tank bladder makes accurate calculations difficult if not impossible. Ambient temperature contributes to the confusion by making the bladder stiffer in cold weather. To add to the confusion, the MFD's (Multi Function Display) MPG is an estimate, although mine appears to be more than 95% accurate compared to over a year of manual calculations (miles driven/gallons).

My advice: Don't try to get the absolute most miles/tank and risk running out of fuel. You just can't tell where or when you will exhaust your fuel and the very limited range of "all electric" could be more than a minor inconvenience. I fill at the last "non-blinking" pip on the GUESS gauge.

 

Sort of depends on what the definition of is "is". First all the reasons stated, then the gasket on the fill port causes many pump auto-shutoff to cut in too early and can make filling the tank very difficult. You might do a search and read past threads.

 

Back in 2015 I ran out of gas and didn’t realize it. Miles driven was about 450 and mpg was showing about 44. I thought I had broken something because all the lights came on. Had the car towed to a dealer. They gave me a stupid sticker along with the bill for the diagnosis. I had run out of fuel. They put 3 gallons in and I drove a few hundred feet to the station and added 8.9 gallons for a total of 11.9. Normally I fill up with 2 pups on the indicator bar and I’m lucky to be able to get 7 to 7

i ran out and it took exactly 11.8 gallons. I keep a spreadsheet for my real mpg and don’t let the pips go below 2 before filling up. My recorded average over 165000 is 43.5. Less in winter and better on road trips
