Got a 1.3 JDm yaris F CVT.. have 185/70 tires..
normal driving, no aggressive stunts.. traffic moderate to heavy on daily 66km drive.
getting only 14km to the liter or 32 MPG..
what am I doing wrong here? or need to do to the car to get it to do some good miles

malibuguy · 07-08-2011, 07:53 AM

i dunno

i used to drive my mothers '07 dodge caliber for a 1/2 year a few years ago, thats a 2.0L CVT & was getting 32-34mpg while using A/C...& thats a much bigger & heavier vehicle

just try to minimize the CVT slip i guess with light throttle use

When I first bought my Yaris it had a full tank of gas. I got about ~55 mpg out of it "mostly highway". At first I didn't really believe it because the sticker said it should only get 29 to 35 mpg.

I noticed I got a lot less mpg when I filled up the tank with new gas. Maybe it's just the ethanol gas stations use down here? Because now I get about 35 to 40 mpg on average. Which is still better than what the sticker said. The Toyota dealership had to bring my car from another state because they didn't have anymore of the specific Yaris I wanted, so I guess they used real gas there.

Also I notice a slight difference between gas stations. I get better mpg when I use Chevron or Shell vs lesser known "non-name brand" gas stations. Although Shell can be more expensive than other brands.

change your driving style. There are a ton of tips in the fe forum, just browse over them all and you will get better gas mileage. Driving for gas mileage is a completely different beast and takes some time to get use to.

I have to commute over an hour to work now, and in this heat there is no way i am turning off my a/c. Worst tank of gas was 39 mpg with highway speeds right about 80 or so. When I give myself enough time to go slower I get better.

In general I am pretty sure neutral coasting will get you better gas mileage, however the hypermilers seem to believe you need to drop speeds around 20 mph to really see the benefits, while with DFCO you get automatic benefits. It depends on your driving style, I am too lazy right now to shift into neutral, so my mileage is with DFCO exclusively. DFCO also works well with my natural driving habits anways, having horrid depth perception seems to be a plus in this instance.

If fuel economy is youir goal, dump the 185s ASAP, and get a good set of 175s. MY 07 sedan really benefitted from the narrower tire, and more rigid walls helped also. Run a few pounds below max printed on the tire. Works for me...

hitmoninfinity · 08-08-2011, 03:00 PM

Hey guys, I'm wondering if you could give me some insight. I just got new tires and wheels for my 07 4 door. Ever since I'm getting at least 20-30 less miles per tank. I'm averaging about 325 miles per tank right now. I had steelies before, but the new wheels are the same size. I guess the new wheels are a little heavier but should they make that big of a difference?!

goliath1812 · 08-08-2011, 03:35 PM

hmm, when I switched over to Konig Heliums (same size wheel) I didn't really notice a difference in MPG, even though the wheels should be much lighter than the steelies...

TLyttle · 08-08-2011, 11:22 PM

Not enough info, hitmon. Are the tires or wheels wider than the ones you were running before? Is the compound or tread design more aggressive than before? Did you change the pressure?

I'm not sure that lighter wheels/tires make much difference to MPG; handling I can believe, but I'm out on MPG difference.

I ran the stock junk tires out (that didn't take long), and bought Hankook mileage tires (not my original choice). Not much difference in handling or mileage once I took the pressure up a few pounds, and they do seem to be wearing much better.

Lots of variables that will change your fuel mileage drastically! Wide wheels eat gasoline, as do wide tires, soft compounds, and tread design. It takes gasoline to push wide, soft, noisy tires, simple as that...

The tires and wheels are the same size as before. Specs say the wheels weigh 17 lbs. Not sure what the steelies weigh. Tires are Yokohama AVID TOURING-S 32ish PSI.

Anyone have any ideas on what else might cause a sudden drop in MPG?

malibuguy · 08-09-2011, 01:47 PM

my last tank was 42.5mpg beating the fuck out of it & locating where the speed limiter kicks in

16.139878951 km per Liter of 87 Regular Gasoline from Petro Canada in my 2007 Yaris Sedan having 89,127 kms on odometer and 15" steel rims. Calculation Method used is 601.9 km in 37.175 Litres.

On average drove within/around speed limits. Journeys involved combined Highway and city with couple of times stop & go on Toronto Area freeways and 60% of the time Air Conditioner was on as well.

Spidermandud · 08-11-2011, 07:44 PM

^37.96 mpg

I had to look it up. :D

malibuguy · 08-16-2011, 11:30 AM

my last tank, 51.9 or .89 something like that

my best tank with the exhaust, but only i think my 3rd best overall

'08 sedan w/ 4 speed auto . 40.63 m.p.g.. Tires at 35 p.s.i..

RT_Smith · 08-22-2011, 09:53 PM

'07 Sedan auto on 175/65R14's with 111,000km driving at ~105-110km/hr and 90+% highway and occasional A/C.

18.24km/liter or 52mpg

I find temperature makes a big difference. The warmer the better.

RT_Smith · 08-22-2011, 09:55 PM

That's on regular 87 octane Shell.
