Gas Mileage

Hey all, so looking at the responses to my "which gas grade do you use" question, I thought I would see what kind of numbers people are getting for mileage. In any responses please note which grade of gas you are using.

Just as an aside, does anybody find the computer to be really optimistic?

So far we have about 1000 miles (1600 kms) on ours, use premium gas and have been getting 23 mpg (US gallons) or 10.2 l/100kms. Although the computer is claiming 26.4 mpg (8.9 l/100 kms)

While this is pretty good, I have to be honest and say that I had hoped for better - I was hoping for my actual to be more like what the computer was saying.

So what do you guys get for mileage?

I am not the sharpest knife tool in the tool box but I am a little confused. ( I have 2016 HSE LUX)

The distance to empty said I have 60 miles today. I filled up and put 12.035 gallons of premium gas in it. The tank holds 18.5 gallons per the owners manual. That says I can go 60 miles on 6.465 gallons of gas or 9.3 MPG.

Also, when I filled it up, it says my distance to empty is only 292 miles. This equates to only 15.8 MPG. I thought it was supposed to get 20+ MPG. That is more then 25% off.

I was so confused by how little gas I put in compared to how soon the car said it would be empty that I completely forgot to write down how far I had been on that tank of gas to calculate the gas mileage. Only the 2nd fill up and the car only has a little over 500 miles.

The distance to empty seems like it is WAY low. No, I would never run it completely out of gas but only being able to drive 250 miles before stopping for gas is going to be a real pain in the a$$.

Thoughts???

Yes this is a known issue.
I noticed the same issue - can't fill more than 14 gallons even when the gauge says it's empty.

It's a software fix to deal with the "reserve" fuel of 1 gallon vs 4 gallons.

See your dealer to fix it.

Todays Update: Went to the dealership this AM and they said that there is NO known software fix or update for the fuel gage reading and that the "car needs to learn how I drive for the system to work properly" - WTF!


The range until empty says I have 62 miles and the car only took 12.035 gallons when I filled it up. It better learn fast because based on these numbers on the last 6.5 gallons of fuel, I will get less than 10 miles to the gallon. (When I fill the car up, it says the range until empty is 282 miles or 15.25 MPG. That's a little shy of the 20/26 MPG they advertise)


Am I crazy or is the dealership full of poo?

I just spoke to my dealership and they gave me a similar response. They said my vehicle already has the "software update" and that I shouldn't let it go below a quarter of a tank because it puts stress on the fuel system.

The system displayed 20 miles left until empty, yet when I filled it up I was only able to put in 14 gallons worth of gas.

Is my dealership full of crap or should I just live with filling up every ~300 miles?

The dealer "fixed" mine by replacing the faulty instrument panel and updating the software, but the issue still remains. Every time I filled up the tank, it always says "distance to empty" is around 290 miles.

BTW, my average mixed MPG is 19.5mpg only. ECO mode only gives me 19.6.

I just returned from the dealership after picking up my vehicle. The computer system showed 5 miles until empty. This time I was able to get 15.5 gallons in the tank.

After filling up "distance to empty" shows 298 miles. My average MPG for the 560 miles on the vehicle is 19.7. Doing a bit of math, that should give me about 344 miles until empty (19.7*17.5). 18.5 gallon tank (minus 1 gallon of reserve fuel).

I did however confirm with the mechanic that the vehicle will not shut itself off if the reading hits 0 miles until empty. He said it was just a reading and not a very accurate one at that. Perhaps the computer system will adjust over time?

I know this is such a little issue but it is a real pain in the a$$. You mean to tell me that a $50,000 car can't figure out at least fairly accurately how far you can go until the tank is empty. Yes, I understand that I could drive like a maniac and that could drastically change how far I can go until it is empty but come on.

It's the little things that make people want to jump off the Tallahatchie Bridge and this is one of them.
