I usually drive 60 something miles to and from work every day. I would fill up every sunday evening to be ready for the week. I drive about 62 miles each way and by thursday I need to fill up again.

I know this is unrelated but I took my 08 Camry SE 4 banger to get the recall done last week and everything is fine.

I filled up on sunday as usual and today I checked the fuel gage and it is a little below the half mark. I am very surprised of this hope stays like this permanently, lol.

Hmmm, thats a little strange. Are you sure they didn't do anything else to it?

All they did was the recall (shave the gas pedal and put a metal backing plate). They even told me I needed an air filter, an alignement and new tires,

My driving habits are the same, use the same type of gas, no additives of any sort.

They probably did what stealerships do best.... SOMETHING WRONG!

Fill your tank to the brim, drive it down low, record miles driven, refill tank to brim, divide miles driven by gallons refilled.

Either you have some miraculous improvement or they muddled up the fuel gauge circuit somehow.

You say improvement but to what degree? Exactly how many MPG's have you gained from this divine encounter?

This is the time of year that the gasoline mfg's change over from winter blend to summer blend.

If you log your fuel usage (the only way I know of to know what's going on with your fuel consumption) you will see a gain in MPG in the spring and a corresponding loss in the fall - I don't know the exact details but the summer blend gas definitely gives more MPG at least on cars with electronic fuel injection.

Beyond that it's possible you ran into some straight gas rather than the now almost ubiquitous gasohol. Regs require gasohol to be labeled on the pump "Contains up to 10% Ethanol" - no sticker, no hooch.

I can smell the difference between straight gas and gasohol, I don't know if most people can or can't.

This is true too. It's not easy to get a consistent full level on most cars, if the car is not level when you pump in the gas, variations in how sensitive the shut-off mechanism is on the gas pump, etc. all make it easy to put say a gallon more gas into your car one time compared to the last.

If you want to really know what's going on MPG wise you would need to average something like 5 to 10 tanks worth of gas, or just add up the miles and add up the gallons for several tanks worth of travel.

Really you would need to calculate the standard deviation in your MPG data (and for this to be valid without weighting it per fill-up volume you would need to buy about the same amount of gas on each fill-up), you can figure your confidence interval from that.

See what happens when you make a simple happy comment and there are engineers about?

new air filter = better mpg. Also, maybe the dealership put the correct psi in the tires. Also = better mpg.
