The telltale tale of one Yaris... bought on 4-18-06 and now at 10,485 miles. I just filled her up tonight...

US gallons I assume? Or imperial!

I really drives me nuts about how both systems use "gallons" but they're different measures!

Ugh.. just annoying trying ot figure out which one often ppl are referring too!

I'm in SC - that's South Carolina. I realize my "location" maybe obscures that little tidbit of information to where ppl aren't sure what the SC means - so sorry. US gallons. Now, go get some sleep. :p

31MPG - Drivin' it hard on this tank, but no AC. Sprint starts and high speed driving. I need to mellow out some...

I once tried taking a trip with 4 ppl and a luggage carrier on the roof. The poor thing was really struggling, I had to floor it a lot. The darn luggage carrier really did need a roof rack, so I deemed it unsafe and returned home after about 30 miles of trying. My point being, loaded-down like that, it really is underpowered so badly, the mpg would have probably been like 20-25.

I was considering taking the Yaris on a camping trip with the wife and 2 kids this weekend. I just don't think we could stuff 4 sleeping bags and our tent in the hatch. I will try though. And a cooler. Maybe one of those folding coolers and I will just buy food after we set up camp. Thinking about Loft Mountain Campground in the Shenandoah National Park, Virginia. I may end up taking the Odyssey though. It gets about 20-25MPG on the HWY...

Darned luggage carriers are almost always designed to be strapped-down to a roof rack. I bungee-corded mine thru the windows, hooked inside to each other. I thought it would work, but the air pushed it back almost to the antena and the front of it made a "wall" that the air blew against. Argh, and the buffeting was getting pretty bad above 60 mph. I was extremely relieved to get it home unscathed, we threw the bags in the trunk of our 32 mpg Infiniti G20T and re-started the trip 1 hour later than expected, all the way to Kissimmee, FL. We would have been in big trouble if we didn't bail.

Got my scangaugeII today and went out and did some research.

I can tell you from just what I've seen so far most of your gas usage is in the lower gears and when your speeding up. While coasting on the highway the yaris gets around 60 miles to the gallon. It appeared to get even around 70 but that was going at around 55. I noticed that the slower you go in a higher gear the better gas milage you get. I guess thats a given. But even taking it very easy on the gas pedal in 1st and 2nd gear you only get around 15 to 25 miles to the gallon.

just the scanguageII gizmo. Here's the website. www.scanguage.com

Its a pretty amazing little thing. Does alot.

wow thankx for the link. Pretty kool little thing. The prius's come with something similar sock. I'm ganna go ahead and order one.....it'll work as an rpm gauge also so

Filled the Yaris up this morning and was pleased to break into the 4's...
654.4km and 32 litres = 4.9l/100km which is about 48mpg for the tank.
Best tank yet.

[sam07yaris]

good . try to get a few extra mpgs in there and beat my 51.2 mpg 147miles @2.7 gallons

[swng]

Update:
Latest tank gave me 45.38 mpg (Imp), or 37.79 mpg (US), or 6.22 liters per 100 km. I started with a full tank and drove 628.4 km and refilled the tank till the nozzle clicked with 39.114 litres. The ratio between city and highway driving was around 30/70 and the AC was on about 20% of the time. The load was driver plus one with some personal belongings most of the time. My city is quite hilly.
NB: The result could have been inflated a little because unlike in the past, starting from the latest tank, I heeded advices about not to "fill till it spill" whilst for the tank before that one, I did just that.
Here are some more details:

are you using a scangauge to measure this?

i dont mean to doubt you... but damn, thats some gooood mpg's!
my best was 44.2 for a FULL tank... 95% highway at 58mph, coasting in neutral whenever i could.

[ItsMyDaily]

do you guys think it would help an auto yaris to be in neutral at red lights or when stoped rather then being on the brake.
I'm to used to manuel cars :D

Your mpg would be negligible -to- zero change. You're in LA. Do you sit in snarled traffic jams that much? I'm hardly ever sitting still, so even if it mattered, the % of "driving" time sitting still is negligible to zero by itself. I would be more concerned about the effects of the abnormally high amount of shifting in and out of "drive". What mechanism(s) might wear-out doing that? I dunno, maybe that's no biggie.

I believe the La traffic is what is getting me in the mpg category. Needless to say I tend to back many back streets to avoid it. I do get caught sometimes though, but not much you can do there. I did not think of anything being worn do to the shifting involved going to nuetral, and back to drive again..hmmm...I'm curious to know if anything would be effected in the long run as well.

From what I've been reading though. People are averaging their mpg's driving between 55-60mph. While I tend to keep mine between 60-70mph. It's kinda hard not to go faster when you drive in LA highways, where everyone is basically speeding. even the people that aren't trying to speed are going over the limit.
