Maybe you should disclose that reading was from one of your track days!

@JROD9496, if you have a shorter geared M/T, expect lower average mpg. Also, as @radroach said, Winter blends sold starting around mid-September are usually 10%-15% lower efficiency than Summer blends.

First things first, check your tire pressures and get your free four-wheel alignment from the dealership then start measuring.

BTW, I don't bother checking since I drive mountain roads short distances and compared to my FJ Cruiser's 13 mpg on Winter premium, 20+ is money so I don't care since I'm having too much fun.

I think it also depends on your wheel set up, recently got new wheels and my avg mpg is 28.

What?!? I baby my car and never rev beyond 3000 rpm! :thumbsup:

Talk about driving like you you stole it! I did that only RX-7 (a lot easier to bash mpg on that one).

Holly shit 9.7 ;)

Almost all city driving & my mpg sits at 27.6 with 7k on the clock. The highest I ever got was on my trip back from picking the car up in Colorado. I averaged 36 mpg on that trip since it's all highway + it was still during break in.

Btw does anybody follow the shift indicator?.. I never did cuz I feel like its gonna log the engine. lol

Same here, mostly highway. Now 34 mpg / 6,9l average for last 2000 kilometers with studded winter tires and only cold weather starts without preheating. Can't complain.

i get 29 mph with mixed driving. about 31 for more highway oriented trips (6mt)

i get 28.5 mpg when i dont wanna fill up for awhile. But when i have the cash to fill up im at 21mpg haha. All receipt calculated

26.2 after filling up yesterday.


Can't resist WOT, need to stop :(


Wait, hell no I don't!!!! :)

I average around 25, with a 60/40 city/hwy ratio, when I do more hwy I get over around 30ish. I don't drive conservative either.

26-28MPG with mixed highway/town, M-F 100 mile commute through horrible I-405 south, I hit all the traffic jams from Boeing in Everett, to M$ in Kirk, to the Bellevue jerks.

This is with a JL 12W6V2 bumping ALL the time, too.

I average mid to high 20's. I've gotten over 30 on at least one tank. It really depends on how you drive the car, especially with a manual. If you want to get better gas mileage I would suggest looking up ecomodder (pretty sure that's the name of the site). If you drive in a certain way you can get really good gas mileage. If you read up on some of the techniques they use and incorporate a less extreme form of them into your driving you should see better mpg's without having to drive like an old lady.

I'm getting about 9.9 L/100km combined since I got my car on Tuesday. It not has about 670km on the clock. Sometimes it seems like the gauge goes down really quickly though. But I have no where near enough km's to get an accurate reading of how it really is. I also have the auto, which seems like its geared a bit more towards better fuel mileage

Edit: Does the mileage suffer while the engine is still breaking in?

Won't lug as they are the "ideal" shift points. Did it for a couple of days and didn't see any difference in mileage but may have a higher impact with all city driving.
Feels like you are playing a really lame game of Guitar Hero (Shift Hero?) if you try to hit the indicator right on.

Shift points won't change mpg's as much as throttle position.

Are you guys not going above 4k rpms or what

Yep! On a regular basis!!!

If I drive conservatively it's 3.5k and below. Anything above that and it's a noticeable decrease. The shift indicator is way too early and thinks the world is flat.

The trick is keeping it above the torque dip. After all the low torque is indicative of inefficiency and that's like the opposite of what you want for good mpg's, right?

If you want the best mileage, you have to think like a modern AT. It upshifts as soon as it possibly can to keep the RPMs as low as possible. If you're waiting until 4k (or even 3k) RPM, that's too high.

Around town in regular traffic I regularly upshift at 2000-2200. That gives adequate acceleration and does not bog down the engine.

To equate it to MPH I go:

1st to 2nd: almost immediately (and don't even leave second for a rolling stop)
2nd to 3rd: 12-15mph
3rd to 4th: 19-20
4th to 5th:28-30
5th to 6th: 38-40

The reality is, from a dead stop I often skip-shift first to third, third to sixth; from a rolling start it's second to fourth, fourth to sixth. Again, this is on mostly level terrain, in regular traffic. On any given tank of gas I still get after it when the spirit moves me and I still do 70-75 on the highway, but the rest of the time that's how I shift and I maintain a steady 30-32 mpg.

This isn't true. RPM is not a good indicator of engine load by itself. It's a good metric to use in shifting, especially with matching the output shaft and input shaft (the main purpose of a tach). Shifting at 3k-4k rpms will, all other things considered, give you better miles per gallon than trying to lug the thing around. I'll explain why in one sentence:

Throttle position is WAY more important- if you're lugging it all the time, you're consuming extra gas.



Anyone who has owned a turbo-charged car will know exactly what this entails

Boooooorrrrrring

P.S. I added 2 to 3 MPG from switching stock tune to OFT's off-the-shelf 91 octane Stage 1 tune.

So excited about that. I am seeing 30-31mpg on the car, up from 27-29mpg averages (typically was 27mpg)

http://www.fuelly.com/car/scion/fr-s/2014/07Vios/287038

Slowly accelerating, camping in the slow lane (when possible). LOL. I'd rather spend/save money for parts than on gas =P

Primarily freeway driving, but I deal with Cali's Bay Area traffic daily (so I would say equivalent to 50/50 city/freeway driving).

I'd just confuse things as we have a different sized gallon! I think we both use imperial miles though (or do you guys use statute miles?)

I 'can' get 42mpg with highway cruising. I 'can' get 35mpg commuting in mixed traffic, but usually it's around 29-31mpg.

However that spread shows that it really depends on how and where you drive the car!

Apparently stating twice "Level ground" ie "average conditions" wasn't enough so I'll state it a third time:

Under average conditions on level surfaces in regular traffic.

No where did I say this is what happens every time, all the time, regardless of the world around me. This is for tooling over to the grocery store for a gallon of milk. That is not how I drive on a track day or how I even drive merging onto the highway.

This method does not "lug" the engine in anyway in those general circumstances. If the conditions are not appropriate for a low RPM upshift, wait until a higher RPM. Yes, throttle position matters and that is taken into consideration.

Also, I'm glad people driving turbos have an apparently better understanding. I think the most important thing to understand is: we're not driving a turbo.


This I can respect even if I don't agree. :respekt: I personally enjoy the fact that I can be comfortably boring in general and have a blast on the track once a month.

That being said I chuckle when folks complain about our low 0-60 times but insist on hammering it from every stop light anyway. You bought the wrong car if you only get your kicks "a quarter mile at a time". :D

Not sure if it's been mentioned becasue TL;DR but the MPG number on the dash computer is directly and entirely related to the throttle % and nothing else. So if your number is low, your foot is heavy. Period.

Don't believe me? Tune for E85. Computer average stays the same but real world MPG's are 5-8mpg lower.

It's just that throttle position is much more evident when driving a turbo platform, sorry for the confusion

While impressive I do wonder if you've ever surpassed 3,000 rpm

You can do Laguna Seca or Thunder Hill in a day, there are some people who would kill for that opportunity, do it! Get one tank in there in <15 mpg! Hell even an AutoX to get you down in the 20's, the car gobbles that stuff up.

I shift at 3k. :lol:

Usually on each tank, I'll floor it in 3rd gear up to 6k rpm as well, just to blow out any deposits.

I wouldn't mind doing an auto-x. I think it'll be fun.

How badly it must suck to be you to have this car and drive like that.

I don't think mine has ever seen a shift at under 3000. Many/most of them are pushing 5000!

I believe the user manual specifically states that shifting before the rev limiter greatly reduces ownership satisfaction and strongly recommends against doing it.

Fuel used = Throttle position * RPM * time.

50% throttle at 1,500rpm will use half the fuel that 50% throttle at 3,000rpm will. (Assuming a linear map, which we don't really have). Maybe a little less, 1-2% less at 1,500rpm.

I use both the instant and average and I work on the principle of how much torque do I need. If I don't need torque to accelerate I shift for about 1,500rpm

Tonight on the way home I was at 30mph in a 30mph zone in 6th, circa 1,250rpm, maintaining speed and the instant MPG was reading 62mpg.

There is an agrument that says, 50% throttle at 1,500rpm to get X torque uses the same fuel as 25% throttle at 3,000rpm, but it doesn't. The higher the rpm the less efficient the engine. This is simply the physics of friction and momentum.

So if you are driving for fuel economy, low revs, high gears, plan ahead, avoid braking and be very gentle and smooth with the throttle.

Don't tell Tromatic, he'll pity your miserable existence. :D

How badly it must suck to have your sole enjoyment be based on racing stop light to stop light (a race you'll lose against a mini-van, or a Cobalt, or a Neon or a...).

I have my fun on track days - cheers! :party0030:

I will just leave this here for you.
