The disk brakes on your wheels also use no fuel whatsoever when you apply them. Yet, one of the effective ways to increase your gas mileage is to drive to use your brakes as little as possible.
If the people at Consumer's Report ever mangage to make a stock 5speed Yaris get 45+ mpg, I'll gladly listen to what they say, until then, I'll take the advice of the group of people who actually do get that kind of gas mileage.

However, if the situation is such that you have to use your brakes anyway, you should leave it in gear and cut off the fuel.
You can actually feel when the fuel comes back on as you coast down, there is a sudden decrease in engine braking when that happens. On my Yaris, this happens at about 17 mph in fifth gear, 24 mph if the AC is on. I bump it into neutral as soon as I feel the DFCO (deceleration fuel cut off) end

Holy crap, 17 MPH in 5th gear. Wont that lug the engine even if not on the gas? That cant be good for it. Does anybody on here do that when slowing down?
