I suck at driving... 8km/L that sucks
 

8 km/L = 19 MPG
12 km/L = 28 MPG


Okay, so I don't know what I am doing wrong... Most FRS Driver get 12 km/L... I get 8 km/L






FIRST TEST:
1st gear shift to second @ 2000 rpm
Other gear shifting to next gear @ 3000-3500 rpm


SECOND TEST:
1st gear to second @ 2000 rpm
Other gear @ 2500 rpm


Am I doing something wrong, every on the car is main component. I am thinking if Toyota or Subaru can reflash the OEM tune.

I average around 30 and that is spirited driving in the city (not shifting till 4k RPM's, or going from 0 to 35 or whatever the speed limit is (never less than 15) strait to fourth, and then whenever getting on the highway it is WOT to the speed limit....

So I can not say what the cause would be unless you do a lot of city driving and hardly no highway driving.

I am okay with getting 20-25 MPG. I aim at this, I do 85% city and very little highway.


However, I drive in the city when there isn't much traffic.


Assume you're in first gear, you will wait till you're 4000 rpm to shift to second? Then wait till your at 4000 rpm again to shift to 3rd?

If you turn on the gear display on the dash it will notify you of the prime time to shift for fuel economy. You should try it out and see if there is a difference.

I get 24.8mpg on the regular, with that decreasing quite a bit each time I add a new mod for a few weeks.

No really the only time I use 2nd gear or 3rd gear is if I am going to be going faster than 35 such as getting onto the highway or racing then I am wot through all gears till I get to the speed limit. Otherwise it is 1st strait to fourth and wot through first. The exception being if I am traffic then I generally shift around 3000 rpm or so.

sometimes if I am not in a hurry (which does happen from time to time) I will shift around 3k or so while entering the highway

I would suspect most of the reason is you are 85% city driving, when you are stopped you are getting 0 miles a gallon, when the car is not moving you are getting 0 miles per hour. When you go to slow down if you simply down shift instead of going into neutral that can effect it too.

didn't even know that was a feature lol how do u turn it on?

It could also be the gas you are running too.

For the most part winter blend gas sucks.

I personally run 93 with no ethanol so that can effect it as well.

I know many people run 87 which according to the manual it is recommended to run 91 so that can effect the mileage as well

What RPM to do you shift?


I go to Neutral when I know I will come to a stop. I don't downshift unless I brake and I lost a lot of speed.


I don't understand the inept car. You mean I get 0 MPG rating when the car is not moving? Just running?

Its on, I tried it.. I get 8.5 KM/L

Shift points have much less to do with fuel economy than how much time you spend accelerating, slowing down and idling and how you perform those tasks. Even a Prius gets shit mileage when you treat the pedals like on off switches.

You can redline in every gear to get up to the desired speed but if you drop it into a high gear and set the cruise control with the rpms <3,000 over a long period you'll get great fuel economy.

Since you're constrained to city driving it's going to be tough, you need to be very smooth with your foot inputs, accelerate briskly but not quickly, it's better to get to cruising speed sooner rather than later as you're wasting gas stretching out the acceleration time. I've heard before that you should pretend that there's an egg between your foot and the pedals, the metaphor is a little silly but it gets the point across: gentleness.

The biggest gains will be slowing down, coast in gear as much as possible, anticipate traffic as far in advance as you can and minimize your brake usage, downshift through to second to get maximum coasting in gear. By doing this the fuel injectors shut off meaning you're burning basically no fuel.

I'm sure you've figured out the obvious tips, not zipping between lanes doing 5+ kmh over the limit and all that, you can try drafting as well but at city speeds (<55km/h) the gains are small compared to 100+km/h on the freeways.

Good luck and honestly you aren't doing so poorly that I'd worry something is wrong with the car, sounds like you spend a lot of time idling and that's just a consequence of your situation, anything you drive will fall short of the average expectations (the 28mpg mixed vs ~21 mpg city)

It's because you have no load bro.

I will idle less, that's my next test. I think the car starter is taking my gas away lol (I'm in Canada).


I don't understand what you mean by accelerate briskly but not quickly. You are saying to accelerate kind of quickly or not?


How should I coast?

You want to get up to speed quickly and maintain a constant speed, this will be more efficient than very slowly accelerating over a long period of time, you don't want to put your foot to the floor though, maybe 1/8 to 1/4 throttle for me.

When you anticipate slowing down up ahead lift off the gas pedal, let the car slow itself down without using the brakes, downshift when necessary so you don't lug the engine, keep the engine >1,000 rpm.

I usually shift at about 3k-4k rpm. I've lost about 60km per tank with winter gas now, and I've only pushed the car once since it's been winter gas.

I assume you're also breaking the car in right now. That would probably affect it. It's better to rev a little higher with less of a load than it is to force the engine.
So it's better to rev to 4k while not pushing the pedal too much than it is to shift at 2k then put your foot to the floor to try and go faster.
Also, as you learn the car you'll see where the power is and when you should shift.

Veux tu une explication en francais?
