Fuel Efficiency and the Yaris

[galactic7gecko]

This is all fascinating info. I have changed my driving habits/maintenance somewhat since discovering this thread. I have a couple questions though. My record MPG is only 36 and this was taking it slow. I have a 3 dr hatchback AT, tires are at 36 PSI (maximum recommended by manufacturer), I use the recommended oil, I just ordered a scan gauge II. I would be ecstatic just to break 40 MPG! I coast whenever possible and shift to neutral whenever possible. I hope the Scan Gauge guide me.

Does anybody have any other recommendations or do I just not have an efficient version of the Yaris!?!?

Thanks!

Slow down. Seriously, if you think you are driving like your grandmother, you are prolly going too fast. And pretend their is a grenade under the pedals. The less you use them, and the softer you press them, the better your gas mileage will be.

What's your commute like? Is it mostly highway or city? Is the terrain generally flat or do you have a lot of hills? What's the average temperature when you're driving? These are other factors that affect your MPG but the biggest thing is driving.

[galactic7gecko]

My commute is around 20 miles round trip its mostly flat except for the freeway where it tends to get a little hilly with the exits and ramps and all. The avg temperature of where I drive is around 90 is this beneficial?.. Sunny Corpus Christi, TX... it always seems to be hot! The highest mpg I've managed to achieve is 36 mpg is this because I have an automatic transmission? Thanks for the replies KrazyDawg and Why? I just installed my SGII and I'm awaiting to see how this tank goes. I'm really hoping to break 40, any other words of wisdom?

[why?]

so you probably use your a/c all the time, that doesn't help, but i wouldn't turn it off either.

The SG2 is a great thing to have. Use it, and it will help you get better gas mileage.

Sorry if i've been living under a rock, but what's an SG2?

Oh...that's wicked. i'm gonna have to pick one of those up.
Thanks man.

I'm I could increase one thing in regards to the particular exhaust strain problem. I will be today about my own next pair of auto tires about my own '99 Corolla. This kind of established will be the same for the established I needed earlier. These kinds of auto tires are usually Kumho 795 Vacationing A/S. For your initial established, My partner and i preserved the particular recommened strain (this could be the strain outlined around the driver's door) which can be 25 PSI. These kinds of auto tires donned as a result of the particular use cafes with 55K a long way and also My partner and i averaged thirty five MPG above this period (roughly 90% interstate and also 10% metropolis driving). Once i obtained the next established, the particular exhaust person My partner and i obtained these coming from recommended My partner and i work these with 5 PSI on the advised strain. This individual mentioned not merely would certainly my own miles increase, yet thus would certainly treadwear, managing, and also path noises. This individual has been proper. My partner and i will have concerning 50K

Two fill ups ago I had the first oil change and had them put synthetic 0-20 in my 2012 Yaris. Since then on the past two tankfuls I got 43.4 and 43.2 MPG.
In addition to synthetic oil I run 40 lbs of pressure in the tires.

[KentSzabo]

I am on my second synthetic oil change with over 10000 miles on it and at the last fill up I got a calculated 44.4 MPG, awesome.

Here is something interesting I found by accident, When I first got the car I installed a cold air to help My MPG in 2007(I was at the most getting 33 MPG combined) I changed back to stock in 2012 and my MPG increased 6 + miles per gallon..Whaaa Who..I might add I drive 75 to 80 miles an hour on freeway, stock tires now with max air 50 lbs..

[Spidermandud]

That is interesting. Perhaps the CAI helped your foot slow down, so now that you moved back to stock it's natural for you to not stress it as much? Not sure :l

Did you notice much difference reverting?

Does it make much difference if i gas up at night than throughout the day? and i heard from a good friend of mine that if you gas up notice that there are 2 - 3 types of levels in the nozzle of the gas pump. you only put in in the first level. (or the slowest pump) as to get more gasoline :) is this true? :)

[charles nelson]

I found that my driving follows the 'Popular Mechanics Fuel Economy' advice. Buy 91% (non-ethanol) gas if price is less than 120% of ethanol gas (has more energy per gallon),
watch upcoming signal lights to sync with green before you have to slow down or stop, if you have auto-trans...accelerate smoothly and quickly to get transmission into higher efficiency upper gears, use A/C if speed is above 30 mph.

I don't think it matters much what time of day you fill up. However, a slower pump will allow more air to escape your tank when filling up. Trapped air will cause the fuel to come up the filler tube and trigger the automatic shutoff on the pump nozzle. Some people think the tank is full when the nozzle clicks off and just puts the nozzle away without topping off. A slower pump will allow more fuel to enter the tank before the nozzle clicks off, so you end up with a fuller tank. If you're one who tops the tank off, none of this really matters much.

My '08 Yaris gets 36mpg during the winter months and 40mpg in the summer. I think the colder temps have something to do with this, but I also found out that gas stations have a summer fuel mix and a cheaper winter fuel mix. The different mixtures and the temps combined probably cause the difference in mpg. Of course, I'm not a slow poke when on the highway, so I could get better mpg if I tried.

Popular Mechanics Mag tested driving habits and mpg. They found that with an automatic transmission they got better mileage if they accelerated quickly but then tried to coast to a stop. Going faster more quickly put the transmission into the higher more efficient gears more quickly. Slow acceleration kept the cars in the lower mpg range longer.

Not for manuals. You control your RPM shifts.
