I know, probably been done a million times...............

having owned a MY03 STi PPP for nearly 2 yrs, its got to go due to the arrival of another kid and the missus giving up work - the 19-20 mpg is just too much, particularly as I do about 15k miles a yr.

did own a MY01 WRX before that, which used to average about 23mpg.

was wondering if anyone with an 03 WRX really gets anywhere near the claimed 30mpg? anyone regularly get 25?

could do with honest answers please, as 25ish might make all the difference to being able to stay in Impreza land.

use to get 23 out of my old standard uk turbo and that was 150kgs lighter. 30mpg would need to be a long motorway run or not using the turbo.

I get 25ish mpg with my MY03 JDM STi though this is on the motorway at approx 80mph, i doubt id get 20 in town

Tony

PS, my MY00 PPP'd turbo use to give me 30+mpg

Jamesemt

I get around 25mpg per tank...but that is only back road blasts for 50 miles - the other 200 or so miles are commuting (I never fill up on empty...)

If you fancy some kind of swap...then email me off the board!! (Sorry, had to get that in ).

chrisp

in two year my 98 uk never got any better than 25.

heres one for you

if your speedo is 10% overeading its your odometer 10% out as well

TonyBurns

I took into consideration that, my speedo was 3% out and i still got 30mpg

I even nearly made 40mpg when running the car in (now thats scary!)
Though i never repeated it again

Tony

chrisp

lol I only get 35mpg in my 1.6 focus, must be me

pbee

when i first had my my03 i was getting 33mpg on motorway runs and averaged around the 30mpg mixed driving, the car is now modified and im not sure i want to work out the mpg.

if you leave it alone you should see 30 mpg

chrisp

do people do this accurate or guess, heres how I do mine (rightly or wrongly)

i.e. :

1) fill to brim
2) reset trip counter
3) empty tank
4) fill to brim
5) reset trip and note distance
6) take number of litres divide by 4.54 to give gallons
7) divide number of gallons into distance travelled to give mpg

CRAIGFIN

Chrisp,

Thats exactly what I do. There is no more acurate way than that to work it out.

Craig.

Andy-pay

yep, thats how i work mine out.

any WRX owners like to add comment??

WRX03 PPP = Max 33.3MPG on a very long drive, car full of luggage, an hour or so stuck in traffic in Welsh towns, and a lot of motorway driving. Normally around 27 MPG with a mixture of point 'n' squirt driving on the b roads and some motorway driving.

Andy-pay

27mpg sounds promising!

did you ever run the car prior to PPP, and if so did the PPP make a difference?

Jiggerypokery

Only the first 1000 miles, and that was very gentle. I would guess the PPP would make it easier to achieve better fuel economy, because you can use the higher torque low down in the rev range instead of always using the turbo.

Nick100

Standard MY03 WRX. Have religously recorded mpg from about 500 miles to 17k now. Sad I know. The mpg is improving with mileage, as the engine loosens up more.

Don't always run tank to empty but sometimes down to 1/4, but always fill to brim and record mileage.
Best ever on a tank full : just over 32mpg on a long motorway and steady A road run. Worst 17. Average is about 27-28 with a fair amount of motorway running.

DJ140

I average around the 25 mark. 80% of the driving I do is on the motorway though and I would guess it drops to around 20-22 around town.

WRX03 PPP = better MPG!!!

pbee

there is a slightly more acurate way to work out the mpg

fill the tank up, reset the odometer, use as much as you wish, fill the tank up and keep the reciept for the gallons / litres and record the odometer reading, you now have a exact (well debatable) figures to use rather than guessing where "empty" really is.

you can now work out the mpg every fill up rather than having to run it dry all the time.

Once got 31mpg on a trip from Halifax to London but i never went above 70mph as it was really pi**ing down for the whole journey and most of the time i had to cruise between 50 & 60 (boy was that a boring journey) but most of the time i get about 25mpg

Jamesemt

Most people do this anyway, mate... I have a program in excel which does it all for me cos I'm a bit bad at maths.

WRX Jase

03 WRX PPP

Had getting 29 - 30 average over a year (25K miles).

Plenty of long Motorway runs though but the odd bit of town and country work ;-)

SL_WRX

My MY03 WRX Wagon's best with a few average runs but mostly around town was 23 MPG, average of 22.

Lets face it - unless you are always doing motorway miles, you aint going to get anything much better than 25 mpg.

simpsons !

My wrx MY04 has now done 5500 miles and i'm averaging 26-27 mpg, would say about 75% is motorway running and i cruise at between 70 - 80 mph. Hope this helps you stay in scooby land !

Tony, those are pretty remarkable figures. I usually got about 25mpg out of my MY00/PPP and I'm seeing about 22mpg from the STI. The best I ever had was about 33mpg during the fuel crisis, and that was depressing in the extreme

Andy-pay: why not enquire about a Tek 3 remap? Maybe one of the tuning firms could map the car for economy rather than power - it might be cheaper than selling the car and buying a new one.

Andy-pay

hadnt thought of that.

seems the WRX's are a bit better than the STi then, pretty much what I thought - just need more peeps to be getting over 25mpg, to convince the missus!

Barmyclown

Tune it for economy , is a good idea, you could always use it as an excuse to replace one cat with a sports one, ditch the others, free flowing exhaust and, new manifolds. Then Tek3 for an economy tune , you should still see a small improvment in bhp an torque plus better economy. Or use the switcheable map feature in ecu , and have one economy map and one of a bit play map.

Was this PPPd when you bought it - experinece with NA Alfas has convinced nme that "performance" mods can give better MPG when the performance is not being used.

Not sure how relevent this is to turbo cars but would definetly like to improve the MPG on my bog standard MY99 (with Subarau warranty - hence the interest in PPP differences)

chrisp

If remapped correctly the air/fuel mixture should be better across the rev range thus giving better economy. Scoobs overfuel at top revs as protection but means they run rich and use more fuel if you use high revs. Obviously by remapping your are removing some of this protection though, a good mapper should be able to tap into this and give you best of both worlds.

wrxmania

I get on average between 220 and 280 miles for £35 - £40 Optimax, equating to about 24 MPG to 29 MPG. Pretty good for the car, and that is mixed use, a lot of congested traffic etc.

I think the PPP has made my economy worse - but this could be I just drive the thing more enthusiastically I suppose. But 19-20 seems to be about the norm for PPP STi, having read other threads.

who could do the 'economy' switchable map then?
