FA20 is VERY fuel hungry
 

Has anybody noticed the surge of fuel that is used when you stomp the gas? Im not sure how much it uses but dang, gotta say its kinda scary! I mean it gets up and goes but it uses alot to get there.

All engines use lots of fuel under acceleration ...? Not sure what the issue is here. Are you meaning that the mpg/lper100km indicator actually shows it and thats why you think its high?

your right foot is VERY heavy.

I dont really notice that much of an increase in fuel consumption when pushing the car. 4 Cyl for the win

I can damned-near hear the gas drain from my tank when I step on it in my truck. Even pushing it for all its worth, I get much better gas mileage in the FRS than I do from that, so...:iono:

I get 15mpg in my van when I'm hyper-miling. So yeah, there's that.

anyone else notice the harder you hit your head on a wall, the more it hurts?

yes, my right is very heavy.. at times..lol. I mean in some spurts where I have been able to hit a triple digit speed, doesnt happen often.. Im also reving to 7k as well and shifting. I know its how long you accelerate for too. So yeah it adds up, but still, I shouldnt be able to see that much of a difference in a couple of seconds?

Never tried, sorry. Tell us more about your experience.

The last three sports cars I've owned were pretty awful on gas, particularly city gas. Oddly enough, my vette got 30mpg highway, so the average was the best of the three. The FR-S over this last week seems to be averaging 25mpg. I think that's fine. As good as my vtec accord.

I remember resetting my fuel average before doing a 1/4 mile run on my motorcycle. With burn out, staging, pass, and return to staging i averaged 15mpg on a bike that returns 50mpg on the freeway. Full throttle applications will be thirsty no matter what kind of vehicle you drive.

A buddy of mine has a built chevy 360 in a chevy monza that runs low 11's and he gets about 1-2 mpg going down the drag strip.

That right there makes a huge difference. Running the car to redline vs running the car to 3.5/4k is going to make a huge difference in the gas you use. And flooring it to get to said points make a difference as well. I get 30mpg in the FRS if i'm not putting it to the floor at every stop sign/light. Having fun every once in a while (basically when I dont have a pile of traffic around me to hold me up), I am still managing 28mph ish city. Of course, if i'm not going to floor it, I shift at 3k-3.5k. :burnrubber:

For commuting I actually shift at 2500 if I'm not really in any kind of hurry (aka in traffic and stuck behind people anyways). Weekends/evenings are different obviously

on weekdays im very casual and let the carshift on its own to keep the gas mileage up.

All vehicles are that way...../facepalm

I've had some pretty varied tanks, my best was 34.6MPG. (After I installed my coilovers, been driving sloooooow.)

And my worst was 26.4MPG, I'm pretty sure I did a lot of pulls on the highway, haha.

Comparison of past cars I've owned over the same daily commute:

- FR-S: 28 mpg
- GTI: 24 mpg
- STI: 19 mpg
- RSX: 30 mpg

Is it fat out the back (black smoke)?

This thread has to be a joke....

My guess is the OP is driving his first car with an MPG indicator. My Jeep drops to damned near 0 when I gun it. It shows instantaneous MPG. If you were to continue to 'mash it' for a whole tank you'd get absolutely shitty range out of that tank.

Pretty much sums it up. Sure I'll hit ~50L/100kms when accelerating ... but I accelerate for what 100m then I'm at a steady speed. Thats why you'll get worse mileage, but instead of getting 8L/100km you'll get 9 or 10 L/100m

A built supra turbo will use a gallon per minute at WOT. That is fuel hungry.

There is a joke here. ;)

YOU, are very, very good (in my best DeNiro impression) lol

You. You're good you. :D

I'm getting 31.1 mpg currently on my frs

Yeah, but you're not DRIVING IT TO THE MAX, BANGIN' OUT EVERY GEAR LIKE UR ON THE 'RING like some of the more "special" members of this forum

I got around 24.5 on the tank I did highway pulls. The gas station where I filled up had a CONTAINS 10% ETHANOL warning, whereas other gas stations that I've filled up the car don't have it advertised and I got better mileage. That might just be my right foot on that one tank though...

Ethanol-free fuel definitely gets better fuel economy. Definitely.

The catch is that the other stations where I fill up aren't advertised as "ETHANOL FREE" I just can't find the "CONTAINS 10% ETHANOL" sticker. Ethanol has a lower energy density than gasoline, so getting less MPG makes sense, but without testing my ethanol content I'm really just speculating about the EtOH content of these various stations.

This thread is even funnier because there's a thread just a few down about a guy saying he's getting 40 MPGs, LOL!!!!!

Everybody move along. The Troll's feeding time is over.

All this talk of consumption is making me hungaly...

It's almost as if that pedal you press to go faster is called the gas pedal

^ lol

trying to be constructive to this thread:
VW R32:16-20MPG (3.2 VR6)
BMW 135i: 18-22MPG (3.0 I-6 twin-turbo)
FR-S: 22-28MPG (2.0 Boxer-4)
I'm as they say a spirited driver, sometimes more than other so consumption obviously varies.

In summation, you want to get better gas millage get a Prius.
1.8 I-4 hybrid 50MPG :thumbsup:

The engine does have two fuel delivery systems, port and direct. My guess is that it can deliver more gas under load than unitary systems.

So let me get this straight:

Your other car is an S2000, and you complain about fuel consumption with this car?

Do tell...

The preferred nomenclature is "accelerator" :bellyroll:

This thread. 8/10.
