The EPA estimates and manufacturers' are a good barometer BUT, what MPG/MPL did you really get on your last tank of fuel?

Houckster said

Here's something else. I have a set procedure for refueling. I park so that the tank will fill as completely as possible to the shutoff. Then, from experience, I add 2.2 gallons more. I do this, of course, to minimize the variation in how full the tank is.
..
==========
consider this...
==========
...
When you add 2.2 gallons of gasoline more to your fuel tank after the first shutoff - you probably overfilled your fuel tank above the amount it was designed to hold under varying temperature conditions. The extra gasoline you put in will likely fill the fuel tank's vapor release valve which releases gasoline when the volume of the gasoline expands due to its temperature rising above the temperature it was store at in the gas station's pumps ( see Ideal Gas Law). In cold weather, gasoline isn't likely to expand in volume but in the summer gasoline may expand in volume if the temperature get high enough some of your gas is then lost as gas vapors from your fuel tank's vapor release valve. The risk of losing gasoline via the vapor release valve is minimized if the extra gasoline is burned immediately. The lost of fuel via the vapor release valve can lower a vehicles overall fuel efficiency.

Better than it was on the previous tank-full, gas prices had dropped somewhat our area, No calculations needed, just economy driving habits still. All leaving a bit more pocket $$ for other frills spending! Great!

35MPG with non-ethonal regular. Smart FourTwo 2012. non-ethonal premium give a few miles more but is too expensive around here. 10% ethanol drops the MPG to 30<32 MPG

Houckster sez...
There has to be a reason but I don't know what it could be.

If It only happens once you may never know...
If it happens intermittently then it's like chasing a haint.
If it's constant I know you'll find the problem...

You know that truck inside out... it's just a matter of time.
It would be interesting to know... keep us informed...

Years ago I faintly remember something about an issue with a fuel tank/bladder... don't think Rangers have bladders...also something about a plastic (I think) tank and something to do with faulty vacuum recovery...imploding tank or something like that.
But I don't remember it being Ford...
Unfortunately "REMEMBER" is the key word. (CRS)

My ride is in a garage so no one has access to it and I don't have any friends who would even think of adding gas to my tank.

I couldn't ever say anything about gas mileage after that without everyone busting out laughing. Now that I look back...yeah I guess it was pretty funny.

My last tank fuel yielded 20.531 MPG which is very good relative to the EPA estimate of 14.985. That's 137% of their fuel efficiency expectation.

Here's something else. I have a set procedure for refueling. I park so that the tank will fill as completely as possible to the shutoff. Then, from experience, I add 2.2 gallons more. I do this, of course, to minimize the variation in how full the tank is.

A couple of days ago, I filled the tank as I always do and I found that my latest tank of fuel seems to be yielding 24.844 MPG. I am unable to determine just why this is happening. It is possible that maybe the last purchase of fuel which should be E10 may have been E0. It is also possible that I added more of the fuel helper solution than I normally do.

Of course, despite my precautions about refilling the tank the same way each time, there may have been a problem somewhere that might explain why I got the current reading. Hopefully there is no problem.

I'll know more after a couple of more refuels.

reb4:
Yeah sometimes I use Plastic...Usually when I'm buying 50-75 gallons of a mixture of fuel (Regular/Premium/Diesel)... Pain in the a$$ to run back and forth to the cashier multiple times...

I live in the "Boonies" so the local retailers "Gouge" on the prices so I keep "stocked up"...

Most of the time I just pay cash...regardless of whether there's a discount or not.
I try and use each card once/twice a year to keep them active. I very seldom carry a credit card. (Only when travelling) I cancelled all debit cards...

It's amazing just how many people have lost the ability of counting money, especially counting back change. LOL

We're about as different as daylight and dark....

THat's pretty good price OldHillbillyAZ... I rarely pay cash, don't carry enough with me to do so, and usually not worth the difference, since I get cash back on my credit card purchases....
