415 miles today!
Went from Oakland to Reno and back on one tank! took 10.5 gallons to fill, with an average speed of 64 mph. So 39 mpg.
All readings off a GPS. |

Not bad (really good actually), especially with those hills/mountains. lol. You should get a Scan Gauge II. It'll be very beneficial. Also, I don't recommend letting your gas tank fall below 2 bars. I let my tank get down to the blinking bar, and I kid you not, my mpg's went from 42 mpg to 29 mpg for three tanks, and then started climbing back up. I think some low laying debris got sucked up???? I never let my tank go below 2 bars now.

That's pretty darn good, considering that it includes climbing from Oakland to Emigrant Gap on the way up and Reno to Emigrant Gap on the way back. The best MPG I've gotten on a tank in my Yaris, if I remember correctly, was between 48 and 49 MPG from Winnemucca, NV to San Rafael, CA.

Good, good. Let us know if you see a decrease (or increase) in your next few tanks. ;)

That's weird. You get better mileage filling up more?

I took it as filling up more often (like filling up to half tank only). I should have probably read it twice. I will re-reply to him.

Since I wasn't sure if you meant filling up more often, or filling up more per fill up, and since I answered in terms of the former, I will answer for the latter now.
Filling up more per tank will not get you better mpg as it'll be adding more mass/weight to your car. I fill up to full because I don't want to have to keep filling up often, so I take that mpg hit. I don't let my tank go lower than 1/4 tank (which isn't really 1/4 tank because the gas tank isn't a perfect square) because in my experience, it did something that caused my mpg to decrease a lot. I'm assuming it's sucking up sediments/debris that settled at the bottom of the tank or something. |

If you do not commonly let your gas tank go to near empty, you should not start doing it, because Kaotic is right, crap sinks to the bottom and sucking anything up could cost lots of money.
I never fill up until the bar starts to blink, and I almost never have to put ten gallons into my car.

Any and every automobile gas tank has the gas taken out from the BOTTOM. The pickup tube might be located on the top of the tank, but inside, it goes down to just about the bottom, NOT Flush, to the bottom, but almost. Think about it! Otherwise, how can the gas get emptied while driving anyway??? Next time, try drinking a drink with the straw half way to the bottom of the glass and see if you can empty the cup. |

Why do you feel the need to post in bold large font?
If you want to run your tank near empty, so be it. I do know that the pick up line is at the bottom, but that does not automatically mean that any sediments will be sucked right in. Furthermore, the fuel pump is in the tank and is cooled and lubricated by the gas, so by letting your gas levels lower, you take away its lubrication. This can damage it. So, even if you don't believe in the sediment reason, it's still bad to run your tank near empty, unless you don't mind replacing your fuel pump more often than it normally needs to be. |

I guess I must have gotten a 'Wednesday' fuel pump . I almost always take my tank as close to empty as possible before filling up. The original fuel pump still works, and I'm still getting over 40 MPG combined.

But yeah, I have no clue how much shorter running your tank near empty will do to your fuel pump's life. May not see it until ~150k miles or somewhere near there. |

Think about it. acting like an asshole does not make you correct. It just makes you an asshole.
Your logic is flawed. No tank is perfectly straight anywhere. Crap will always fall below the gas level, and unless you run the tank near dry, it will stay there until the car is crushed. And the Yaris' inner liner is rubber. That means the weight of the gas will always flex the bottom lower. But most importantly, something believed and repeated by so many people for so long usually has a kernal of truth somewhere. Look at what we call old wives tales. Science is finally catching up to their truths. Quote:
