Good observation buddy! But trust me, I am going to report better numbers with the next tank

i think i have hit the wall with getting better mileage, most of my driving is short city trips (so basically the worst type of driving for fuel economy)

i figure if i can keep it above 30 mpg in the winter, then i'm fairly happy :)

stuffy · 01-11-2007, 09:26 AM

you will get better mileage as the engine gets worked in.
i've had my car for 14 months and 34.4 mgp is the lifetime avg i have achieved.
the best mileage i've had was 45 mpg this past summer on trips with 100% hwy driving.

How do you know how do you know all that? A computer in your car?

no, i just keep track of mileage the old fashioned way.

07WYarisRS · 01-11-2007, 10:15 AM

Keep in mind when the tets are done for in town and hwy mileage they are done in a strait time with few cold starts and shutting the car off. if you fill up you car and drove it intown for a full tank of fuel without shutting it off you will easily hit the toyota mileage claims. Same with the hwy. If I fill the tank and drive it until empty with no stops or cold starts I can easily get toyota's cliamed mileage or better.

So much depends on the driving style, when you drive, where you drive and how often you start your car.
During the week our mileage sucks because the is driven 5 minutes from the house, at lunch the wife drives home, an hour later she drives back, then home again. 4 cold starts = 4 cold 5 minute drives. The car barely gets up to normal operating temps before it's parked again and this KILLS the fuel economy. but it's a far cry better then our truck was LOL.
The more short trips or in town the worse the mileage will be.

Also I get FAR better mileage driving then my wife does and we both follow the posted speed limits most of the time.
The difference is I tend to accelerate slower and coast longer, where she uses the brakes a lot more and has a heavier foot. When she drives the car is shifting aprox 500 rpm higher then when I drive.
Also the speeds you drive on the hwy make a huge difference. Drive 100kph and you will get better mileage them driving 120kph.

There are a few things you can do to improve the mileage as well. The biggest difference for our car was switching the fluids over to synthetics
Amsoil 0w-30 engine oil and Amsoil ATF. I can get crazy mileage (over 50mpg) if i drive on the hwy and keep it at 100-105kph and that's with an auto and car full of camping gear.
Do not over inflate the tires... so many people do this and think that it helps, follow the mfg's recommended tire pressure, it's on the inside edge of the driver door.

So how's that Amsoil ATF? Did you change it yourself? I want to do this but I'll probably pay a shop to do it.

Thanks for that man.
Great comments, glad you posted that so I could read it.

It really appears most of the gas will be used in acceleration. So go easy on the acceleration. You can cruise when your up to speed on the highway and get probably close to 45+ miles to the gallon. But where most of the gas is used up is as I've mentioned in the acceleration to a cruising speed.

TYPICAL TECHNICAL PROPERTIES
Revised as of 12/06
AMSOIL Synthetic Universal Automatic Transmission Fluid (ATF)

Kinematic Viscosity @ 100°C, cSt (ASTM D-445)

6.8

Kinematic Viscosity @ 40°C, cSt (ASTM D-445)

33.5

Viscosity Index (ASTM D-2270)

168

Noack Volatility, % weight loss (ASTM D-5800)

10.2

Flash Point °C (°F) (ASTM D-92)

222 (432)

Pour Point °C (°F) (ASTM D-97)

-52 (-61)

Four Ball Wear Test, Scar in mm; 40 kg, 75°C, 1200 rpm, 1 hr (ASTM D-4172B)

0.40

Brookfield Viscosity (cP)

-20°C = 1298

Brookfield Viscosity (cP)

-40°C = 9326

The question that I have is that it says "AMSOIL ATF is recommended for transmission, hydraulic and other applications requiring any of the following specifications:" and it goes on to list "Toyota Type T and T-IV"
BUT
The manual says "When changing the automatic transmission fluid, use only "Toyota Genuine ATF WS" (ATF JWS3324 or NWS9638)."

wuddup wit dat?

doesn't seem to match-up...

captainzerocool · 01-12-2007, 01:59 AM

Because this is the fuel economy thread I'll post my last tank from my Camry.

I finally broke 30mpg. In the 5 years I've owned the car, this is the first time. That is nearly 95% highway at around 85mph. Nothing above 3000rpm. I've impressed myself with that feat.

And the car has 228,000 miles....

Racer X-8 · 01-12-2007, 12:39 PM

I remember some testing results yielded a general statement that you use less gas by accelerating moderately than by accelerating very lightly.

Sure, accelerating moderately uses more gas than accelerating very lightly, but what makes it win-out in the end is THE AMOUNT OF TIME it takes to get you to your cruising speed. Overall, the amount of gas you use to get you to your cruising speed (the integral, or "the area under the consumption rate/time curve") is least if you accelerate moderately.

Besides that, you stand less chance of getting run-over by the cars behind you! O.o

ECHOKnight2000 · 01-12-2007, 04:26 PM

I hope this isn't too off topic but where i live (Minnesota) its just under $2.00 US dollars for gas! Imagine that! I thought I never ever see that again! Probably won't last long. I'm sure this will put a damper on Yaris sales...

I don't think many people are running out to get "SUV's" that still only manage 15mpg...

You'd be surprised, this is America, land of the house on wheels, but then again it could be just suburbia.

Racer X-8 · 01-13-2007, 09:13 PM

agreed. you know, we americans are pretty stupid, you ever watch Jay Leno doing his Jaywalking thing on the tonight show? ah, nevermind,,, ppl all live for the moment, and at the moment, there's gas at all the pumps and enough cash in their pockets to buy some, that's all there is to it. sorry huh?

Racer X-8 · 01-14-2007, 09:06 AM

Darn, why did I post this question in another thread?...

Why does the Corolla get the nod for best MPG?
