bike races this weekend: i had to drive up to New Gloucester, Maine both saturday & sunday. a little more than 2 hours each way...

anyways. i just wanted to get there, race & come home, as quick as possible.
so instead of driving at 58mph & coasting... i kept it around 70mph (pizza & beer were waiting for me).

end result: 38mpg average.
not great.. but not as bad as i though it would be.

keep in mind that i also had my girlfriend, a ton of gear, and my bike & xtra wheels on the rack on the back...

Well, here are my stats thus far.

I'm def below the stated fuel efficiency ratings, but that dont surprise me, since I figured they're be in like 'perfect' circumstances.

I think the numbers are not bad, Jem hadar, especially the last tank

.

nsmitchell · 10-19-2006, 11:29 AM

33.1 MPG = Pumped my tires up to 42PSI. 3300 miles so far.

foober · 10-19-2006, 12:59 PM

I've been noticing that if I cruise at 65 to 70 miles an hour on the highway in 5th gear I'm getting 50 to 60+ miles to the gallon. Thats using my scangaugeII device to be able to check on gas usage. Its the picking up speed that uses the most gas. But while cruising you can get rediculously good gas milage.

Here's the scangaugeII website where you can order one if you want. http://www.scangauge.com/

I really recommend it. It tells you so much how your car is working. Great product.

Foober said above: "Its the picking up speed that uses the most gas. But while cruising you can get rediculously good gas milage."
Very very true

. When cruising forward at a constant speed, the car only consumes gas to overcome friction, including wind resistance. However, when the car tries to pick up speed or change direction, it has to consume more gas to overcome inertia in addition to friction.

pdarnell · 10-20-2006, 07:43 PM

Purchased mine in September, it's a red LB auto. I have kept track of my milage since I bought it and the results are below. I just ordered a scanguage II and a cruise control. I hope to break 40 MPG soon.

Thanks, not as good as many here, but im not hating them.

the last tank was so good, bc I had to drive like 600 kms to North Bay and back, with like NO city driving and had no weight at all in my car but for me.

(though I was still surprised at the 43 mpg, bc i was driving 130, 140 the whole way there at back... so i wasnt exactly driving at an fuel economical speed)

I usually drive to TO a lot, so that = 400 ish kms of high driving, but when when i make these trips it always for the weekend, im weighted down w/ a cooler full of ice and a two-four of beer, my bags for of clothes and shit. So that's heavy and extra weight,
.
plus once im IN Toronto, i always end up driving places Downtown, so there's a good mileage killer

I figure thats why Ive only been in the high 30s basically

Thanks for the detailed information Jem hadar. To me, breaking the 7 liters/100 km barrier is really something, especially in the situation that you mentioned above. I feel happy for you! Please keep on posting your numbers here from time to time.
Best wishes for safe and happy motoring!

nsmitchell · 10-21-2006, 06:42 PM

Just changed to Mobil-1 5W-30 at 3300 miles. Let's see how it effects my
MPG.

Shall do, thanks for the words.

haven't gone thorugh my first full tank of gas yet, but I'm down to 2 bars left on the meter and about 290km on this tank, should be able to reach 350... Most of my driving is pretty short trips and not much highway, so it's not that great...

yeah lots of short trips kills the mileage on any machine even more so the colder it is.

Did you buy a used Yaris with 1100 miles on it? How much did you pay?
I have the exact same Yaris and I ain't getting nowhere near 37MPG routinely.
I wonder if some engines were built a little more loose, or if you are just lighter on the pedal than me. Do you have many hills where you live?

Just cuious.

Racer X-8 · 10-23-2006, 06:21 PM

I get 36.0 mpg average. If I drove 110 to 120 miles per day average like pdarnell, I would expect that extra mpg. My driving style is that I don't try to accelerate very hard, I don't care much if the car next to me gets ahead of me (much). I tend to hold my own though on the highway. I get real antsy if I'm being continuously passed. That means I'm doing around 75 to 80 mph on highways usually. Not much around here in the way of hills, definitely nothing around here that you would consider to be a mountain, nothing even close. (Central South Carolina - midlands)

I just started driving my liftback again after having it parked up for 3 weeks. I'm seeing a 5% drop in fuel economy. Granted, the weather had become close to freezing since I last drove the car, but the really really cold weather is still awhile aways. I'm hopping the 5% drop isn't going to get worst as the weather gets colder, or I'm gonna be pissed. I got 33mpg in the last tank, when it's usually 35mpg.

With any fuel injected car your mileage will drop with colder weather

Colder air temps or humid weather = more oxygen and more oxygen requires more fuel to maintain stoich (proper fuel air mixture)
Best thing you can do for you car here in Ontario for the winter is run a synthetic 0w-30 engine oil. If you have an manual trans swap out the trans fluid and replace it with a synthetic 75W-90
I prefer Amsoil or Redline products and they will likely give you the best performance and help restore the mileage the best.
