    I took my 2.5L automatic on its first extended highway drive with a run up to Mt Rainier (Washington) reaching about 5,500'. Average for the 380 mile trip was 32.3 mpg. Could have been slightly better without headwinds along the way. City mpg is usually about 22. This matches the stated mpg claims almost exactly.

    Re: ATS and MPG - What are you getting?

    Does anyone know approx. how much more you can drive when fuel indicator says LOW? Is it ~50km or so?

    Re: ATS and MPG - What are you getting?

    Each car will vary some. If one fills up as soon as the light comes on, then you can calculate the amount remaining in the tank. Simply multiply that volume by the average MPG that is being achieved at that time and you will have the remaining range. This will vary depending on your current mileage, city vs highway.

    You can get a somewhat accurate reading using the OnStar Smartphone app. I think it was 5-7L left in the tank when I checked.

    After 2700kms, I'm getting roughly 19-20MPG with my 2.0T RWD Auto. 80% city driving

    Re: ATS and MPG - What are you getting?

    after 1700 miles or so, seems my driving limits me to between 23-24 mpg during the week going to/from work in 50/50 driving and a partially lead foot. 26-27 on mostly highway when I popped over to northern VA 2 weekends ago.

    right on the EPA ratings pretty much, I'm a bit dissapointed in highway, but that may have been a fact of my 65-75 mph average traveling speed.

    I honestly believe that resetting every fill up is too often. Also, if one is calculating mileage manually based on miles driven versus gallons boarded, one is probably not considering that very innocuous note that appears on every gas pump stating that "volumes are corrected to 15 degrees Celsius (59 degrees Fahrenheit), which can certainly effect the calculations in extreme temperature conditions... All of which brings me back to the idea that resetting the "average mileage counter" at every fill up is a bit too often.
    You're analyzing this way too much. Thermal coefficient of petroleum products is about 0.000950 / (C or K)

    ie, for every 50 degrees in temperature drop, you net 0.01425 gallons. Calculate that the fact that storage tanks are underground, and even when outside ambient is triple digits, you might be 20-40 degrees cooler down there and it all really makes no difference at all. *maybe* a few hundredths in your calculations.

    You're also not considering that the pump's measuring devices undergo thermal expansion as well, and it doesn't necessarily deliver the exact amount displayed. It will deliver what it believes is the volume of 1 gallon of gas.

    if there were tangible variations in how much product you're receiving for your $3.5-$4, I can assure you, there would be huge uproar.

    That's just what we are getting in both situations.

    Now the gears are turning. I wonder if the accuracy is only there at flow rates the system was designed for. It would be great if it read way low if you stuck a powerful pump between your car and the pump sealed against the nozzle and sucked the gas out of the pump at great speed.

    Interesting idea. What I will say is, Convenience stores sell gas to get you to come into the store and spend money there. Typically margins for a gallon of 87 are between 5-15 cents and for premium anywhere between 20-40 cents per gallon. That's before upkeep of the pumps, lights to illuminate them, state regulators coming out and inspecting the units (or tank), equipment repair/replacement, and trying to stay ahead of the other 3 stores within walking distance by .01 cents.

    I would like to believe that they make every attempt to limit their costs with gas.

    Re: ATS and MPG - What are you getting?

    Just returned from a 2700 mile round trip from Iowa to Mississippi. Whe driving at highway speeds I kept cruise on 77 MPH and made passing speeds from 85-90 MPH. Just a guess, but I would believe I had cruise on 80-85% of time. For the eight tank fills I got from 23 to 28.7 on the trip while using 93 octane.

    Before the trip the only other tank fill I can give a representative highway speed result was 30.1 MPG. Since my engine now has a map of long distance driving I plan to do a trip soon to see what a constant 70 MPH can achieve.

    On the road my 3.6 gets 26-29 mpg. Around town with some highway I have been 24-25 mpg. My only issue is when my son (19 years old!) takes it for a drive the mileage miraculously drops 4 or 5 mpg! His only comment is "if you have it then why not use it!". Who would have ever thought a testosterone laden 19 year old would desire to drive his Dads Caddy because it is so cool. This is not your fathers Cadillac!

    I have a feeling it is because of those times when I'm oly getting 9 mpg lol
    So I now have 2,100 miles. Was using QuikTrip 91 and getting between 23-25. I just switched to BP 91 that has NO additives. It is a lot more expensive but I wanted to give it a shot. I'm getting over 28 mpg! I know those "cleaning agents" definately hurt the mpg's

    Federal law (EPA) requires a minimum amount of cleaning agents and I believe BP is on the "Top Tier Fuel" list which has additional cleaning agents?

    I am getting simular results with my 2014 3.6L @ 4000 miles.

    straight freeway is about 30mpg
    straight city is about 17mpg
    80% freeway 20% city is about 24mpg

    what I realize is that everytime the car has to engage lower gear (<4) it masacre thr mpg...

    Yes, QT and BP are both top tier gasolines chock full of additives.
