abysmal mileage!

[MadMax]

No joking here, are you sure no one is siphoning gas from your Yaris?

Also, it could be "winter gas" as well. I noticed I went from a average of 37 MPG to 34 MPG on this last tank. The additional of ethanol does not help either; but your decrease is significantly higher than what I've seen (8-9%)...

Doesn't matter how heavy your wheels are, your not going to see a major drop in mileage. People have repeatedly reported getting similarly high mileage with a full load of passengers (800++lbs) as they do with just a driver in the car. In comparison, wheel weight is insignificant.

yeah, that's what's so strange about this.. i drove from new york to florida, with a car FULL of my stuff, i mean, there wasn't a single free space at all. i even had socks stuffed in every opening i could, just to fit everything in there. that said, i still got between 33-37 mpg.

i've considered that, and even turned the sensitivity up on my car alarm! when i lived in new york, i noticed the difference in mileage from winter driving, but i'm in florida now. i haven't really altered my driving habits much, except i'm now taking advantage of the DFCO as much as possible! lol

A drop to 24mpg seems to indicate some sort of other problem (unless your new wheels are seriously heavy.)

i know that the wheels aren't lightweight. i'll try to take one off and weigh it, but the most accurate i'll be able to get will be my bathroom scale lol. they were cheap off craigslist, so that leads me to believe they aren't.

could it be the fact that i'm now at 65k miles and just, for the first time, used said fuel cleaner? could there be some clotting... idk, i'm just thinking aloud now lol.


thanks, everyone for the input! i appreciate it. i just filled the tank a few minutes ago and reset the trip, so hopefully i'll notice some sort of improvement...
