54.5 mpg, 1st tank hypermiling ('08 Toyota Yaris manual)

[snakester]

A few weeks ago I got gas & checked my numbers and came up with 45.3 mpg and it got me thinking. That's when I found this site and researched new driving techniques. My 1st full tank hypermiling got me 54 mpg and I was astonished. This was before adding air in the tires! After filling up two days ago I bumped my air pressure from 36 to 41 psi to try and tell a difference. The last two days my numbers have been significantly worse than before and at first I attributed it to the tires. But after searching these threads, I am chalking it up to the weather which has been much colder and windy, and am hoping to return to the incredible figures I was seeing last week.
I can't wait to do some more mods, but after seeing Donkey's MULE VX, I might get carried away. That car is awesome.

Good job, keep it up!
I'm probably going to ad a couple of more aero mods on my Festiva shortly, but by far the greatest increase for me came when I read the P&G and EOC threads here and applied them to my driving habits.

Congrats, snakester! Fun isn't it?

Glad you answered your question about tire pressure.

Very nice. Going to have to research "hypermiling"
