embarrassingly bad mileage... REALLY - Page 5 - Toyota Yaris Forums

ozmdd · 04-19-2009, 11:30 PM

Tire pressure and TRULY mellow acceleration are the keys to high MPG. If you've upgraded to bigger/wider tires/rims, you'll also see a slight loss of MPG due to more rolling resistance, but you get increased grip.
I drive "normally", without much attention paid to coasting, and try not to do to much jack-rabbit stuff in traffic, but I occasionally do have to double downshift and pass the ultra-morons on their cell phones. Also, I run some fairly stick tires 215/40/17 (Azenis 615's) on 17x7 Draglites, but I keep the pressure fairly high (35-ish) and the stock TPMS is happy. Most of my driving is city/freeway. I generally average 34 in town. I've gotten 41 on a tank on the highway on this same setup, but it was in the winter (no A/C), 65 MPH on cruise for literally 95% of the tank on west Texas highways (zero traffic, one restroom stop). On the outbound leg of that same trip, I was on the Interstate where the speed limit is 70, 75 and 80 mph, and I only averaged 36.5 with a headwind. The Yaris really suffers above 65-70 MPH, due to the simple physics of drag and a smallish HP rating. I suspect that a 55 MPH long-distance road trip could go well above 40 MPG, but I'd rather spend a few bucks more and get where I'm going in this lifetime.
Hypermiling is a fun game, and I did it quite a bit when I initially bought the Yaris (novelty, $4/gal gas and new car break-in), but I personally think I'm doing my share for the environment by simply driving a Yaris. I like my driving better now that I don't overthink it. Hypermiling is a lot like dieting.

lol, I agree. though I stick around 65+ usually, anything over 65+ and air seems to stack up too easily, almost exponentially

I live in NYC as well, and during the winter, the snow, and the cold make me get around 26-28MPG, this is both stop and go, and mixed highway.

Now I'm getting closer to 28mpg average per tank. But honestly even on the highway in NYC, if its a quite night, everyone including me is driving at 70mph+, and when its the day, the highways are stop and go. Thats all because of the city/people going from long island o NJ and vise versa. Then there are the college kids driving too.

Wait until its the end of July, and there wont be as much traffic anymore.

But also, to add to my low MPG, I am on ADR Model Flite 4, with 205/45/17 Falken 912? tires.

So I know for a fact the day I went from stock tires in the summer, and 35+MPG, I dropped to 30MPG at the best because of these rims/tires. And it just gets worse with the cold weather and traffic. I ain't complaining though, because 28-30mpg is still wirth it. Especially the way I drive lol... heavy foot 80% of the time.

This is neither here nor there but my previous car (2003 licoln LS) would monitor my MPG for me, and It would always amaze me how fast the number would start going down when I was stuck in traffic (bumper to bumper and less than 5mph)

any way, basicly what Im trying to say is if your at a stand still for half the time your running the car than I could see why you might be only be getting half the normal MPG.

I get around 34 mpg consistently, and I drive spiritedly. I also change my oil every 4000-4500 miles, rotate my tires each time, and so on...the worst mileage I got was 26, once. it was saddening-- but it was summer, hot as hell, drove a lot and with many passengers, and I had the AC on all the time. if you're getting below 28, I'd suggest different gas- most gas is now ethanoled down which will lower your mpg a bit, but also no-name pumps are putting crap in there...i think if you make sure your car is in good shape, especially the tires and alignment, and turn off your AC once in a while-- the mpg will look better.
