Fuel Economy

I just drove cross country from Indy to DC. I almost squeezed 40 mpg (39.6). I averaged 65 MPH the whole way. In West Virgina, Pennsylvania, and Maryland there are some pretty good downhill grades and I thought that would push me over the 40 mark, but as most of you know, you have to go up the other side of the mountain and that eats the gas. Overall, not bad for such a hilly trip. On the way back I am going to drive 70 and see if that effects the mileage too much.

Did a fill earlier . Calculated : 41.82 ( 266.4 mis. / 6.37 gals. @ 1 click ) . Hopefully it pumped enough to fill the tank . Showed full . Time will well , if not still likely be over 41 m.p.g.. Continental w/ Eco Plus tires at 36 . About 30% city and the 2 of us for over 1/2 the miles .

I just got 615 km/tank and a 36.502 litre fill. This works out to: 47.59 MPG (Imperial) or 39.63 MPG (US). I am quite happy about it as I wanted to break 600 km. I gassed up shortly after the gas gauge started blinking.

I am running my tires at 40 psi .. and this tank was probably about 200 - 250 km highway driving.

Keep it a goin' .

My new summer car is a mint 06 civic ex manual with only 42000KM, I can usually get 6.2L/100KM in that thing and I just bought my 08 yaris for a winter car to replace a wrecked dodge sx I had for last winter. I must admit I was pretty happy with my first fill in the yaris.

471KM/24.84L fill right to the gas cap lol. About 10% highway driving. I'm a courier in the city.

I finally got up in the high 30's last week, my average was 39.85mpg, but only for a little over three gallons. I wish I took a photo of the receipt before shredding it, but next time! I've changed my driving habit to driving ~62mph on the highway and driving about ~45-50mph local. I accelerate slower and when coming to a red light, I let off the gas and let the inertia do most of the work. I'm greatly satisfied with the results! My lead foot is slowly letting off... =D

I tried to start a new thread for this, but kept getting an error message.

^^^^^ Bump (post #2041) Anyone?

[why?]

haven't seen anything about it yet. I know it's been fully tested on the Nürburgring, but haven't heard anything about deliveries.

, and thanks for the reply.

Some time ago, I tried 98 fuel (was just 3% more expensive than the standard 95 (lowest we get here)).
Guess what?
I felt no difference, the mileage remained the same, too.

I don't know what's actually better, but you can't always feel a difference even when there could be one. It could be a subtle difference, and subtle differences have positive impacts in the long run, not to mention a lot of subtle differences add up to a big difference. To really know the difference though, you'd have to do actual testing with a good sample size and accurately recorded numbers. This will tell you the real difference despite what you might feel or not feel.

honestly, unless you run it on a dyno constantly there is not going to be any difference you can actually feel, and gas mileage changes so much for every degree of temperature, every time the wind blows, etc, that seeing a difference in gas mileage will be hard outside of a lab, which uses computers to drive the car over a pre-programmed course.

Especially with a near stock Yaris. Now add a turbo and a tuner and that is an entire different story.

The only thing I do is try to use different types of fuels because different gas companies use different additives, and those theoretically might help extend and make the engine more healthy. I have no idea if it is true or not, but it does not hurt my mileage.

Unless you are testing something with instruments, higher octane gas for our near stock Yaris is kind of silly.

There is a reason that all of those numbers are followed up by "EPA estimated mileage" because the manufacturers know that it is extremely dependent on fuel as well as a host of other variables. EPA tests are very tightly controlled so you can have a level playing field on those numbers as well as the emissions have to be within the allowable regulations.

True, but the numbers have zero to do with what happens in the real world, unless you let a computer do all your driving and you never ever go over 40 mph. Not to mention never driving in non perfect weather conditions or ever even going outside a lab. The EPA test gets such stupid numbers they need to do a whole host of random math to get the numbers they publish.

The sedan F.E. is starting to creep up , even with the Blizzak snows .

Called a local gas supplier and was told summer blend not expected until 1st week of May . Meanwhile , RBOB is at $2.998 , hopefully it'll stop rising .
