well im only on my second tank of gas right now. I got 18 mpg on my first tank in 85% city driving...thats pretty bad i dont even drive it hard. hopefully the gas milage improves over time

 

average is 26, highest is 29. I'd get better but I can't stand goign slower than 78-80 on the freeway.

 

looking good on the gas.. =)

 

i average about 24, but i have a lead foot and the car's not even broken in yet.

 

I got 22 miles on my first tank, most of which was city driving. It's pretty good considering that it's usually a stop and go for me. Oh, and I'm also still in the breaking in period (just over 500 miles), and just like jaydub, I do have a lead foot as well.

 

I wasn't sure myself... until I let mom drive. She kept it at or just under 70 for an entire trip. I myself can't stand driving slower than 75-80 in some places around here. Ideal fuel consumption takes place between 45-70. The logic is pretty simple; the engine is designed to get the best mileage at lower RPMs. Since you can't Upshift once you hit 5th, you force the engine to run higher the faster you go. Keeping the needle at or below 3k RPMs, you're just sipping on gas.

 

highest was 30 on my first tank... since then it's been dropping

maybe it's because im driving it harder haha, but i do like 70% highway driving. hm. i get about 25ish now

 

Best was 31mpg.

 

Lowest recorded: 24 (mixed)
Average: 26-27 (mixed)
Best recorded: 28.9 (almost all highway)

I recently switched from highest octane to 87, and I noticed that I have been averaging higher = approx. 28 mpg (mixed). Could the warmer weather be a factor too?

 

I got 30 mpg on a couple long highway only trips. In the city it drops to between 21-25 mpg. With gas prices pushing $3 in LA i'm driving real conservative now.

 

The tC is not "supposed" to be run on only 87octane. The Owners manual states 87 OR better. A higher octane will slightly improve performance too, though in most cases it wont be noticed. So, like dieselstation said, 87 is what you should run, at the minimum. If you dont mind spending the extra cash... or if you have a turbo and dont want to detinate, Premium is your answer...Ultra 94 out here in Jersey!

 

i normally get 27 but im now on my 5th tank of gas and i got 29.1. i was surprised, that was 50/50 city/highway driving.

 

26

 

lowest-24
highest-27

About an even mix of city/highway driving.

 

Going to work I drive about 20 miles on the interstate (4 miles on a mountain, down in the morning, up in the evening) and 10 miles on a curvy mountain road. First tank was high 25, last tank was 27.8.

 

who cares...its a matter of maybe 5 dollars....I use v-power..i think it burns faster.

 

I calculate mi/gal each time i fil up. I drive 98% freeway. Here in CA, freeways are most always stop-n-go all the time!! Yet, I still average 27.8 mi/gal.

The best I've received was from Chevron 87. 32 mi/gal.
Worst mi/gal is a tie between Exxon and Union 76. - 25.x/gal

Traffic sucks

 

My "old lady" drives our tC to work every day and goes about 73 miles one way...almost all highway. She drives at or below the speed limit and doesn't accelerate fast at all. The low has been in the mid 20's (when we first got the car) and now it's up to 34/35 for the high end. (A little over 7000 miles now....since the end of February!) We run Mobil Clean 7500 part syn oil and 87 Octane from BJ's.
Funny...the mileage seems to always go down when I use the car.

 

I get a pretty consistent 27 MPG in combined (mostly city!) driving.

I definitely think Scion did a good job estimating the MPG. Of course, if you're buying a car for the MPG, you probably shouldn't buy a tC...

 

20-22 (city) 29 (on a 2 hour Highway trip with some limited city driving) 1,700 miles in the car so far.

after the car is fully broken in I should get more of an average 23 for city.

So I am getting what the sticker says, give or take 1-2 MPG, so no surprise.
