Fuel would have to be £'s per litre or annual miles into six figures I guess before the mpg should worry your pocket half as much as depreciation!

350 bhp classic ra and i can get 190 miles in a 45 litre tank if im careful and go on the motorway, hard driving and im lucky if i get 170...... so average about 13-15 mpg

gingerboy

As a previous TSL333 STI owner I can verify you hit the nail squarely on the head with your quoted mpg figures - pretty much exactly what i used to get.

God I miss the car, however I dont miss filling the thing upwith shell optimax .

glad you enjoyed actually driving the car

gingerboy

Huge understatement to say the least .

I wonder how much a kidney would go for on e-bay , or alternatively how much I would get for two very cute children and a pregenant wife .

Lets hope the wife doesn't have a look on here today otherwise I am dead meat.

I was being reserved

I'll start the bidding on the kidney, lets say £50? there's a potential 200miles travel for that

gingerboy

£100 and you have a deal, I onder if the wife is still up to speed with the removal of a kidney using only a kitchen devil.

Basically the cost when driven 'normally' say 60mph - 70mph on A roads and motorways is the same when I was on 284 bhp and 283 torque to now that Im on 340ps and about 360 torque. Of course the difference is when your foot hits the right pedal yeeeeeeeeeehaaaaaaa

Under 350 bhp if you guys cannot get 300mls to a tank, around 25mpg of normal driving, you are either doing lots of cold starts and all urban/town driving, there is something wrong with your driving style or your car is badly set up.

jd5217

try living over here then with lots of short journeys and a 35mph speed limit.

gingerboy

Best I ever saw was 280 miles and that was driving like miss daisy down to cornwall from South wales with the odd spirited splurge.

If you are achieving 300 miles to a tank good on you.

Agree, 250 tops for me, and thats with the red light being on for 10 miles or so

......get out the slow lane

Spot on can normally get around 320 miles out of 55 litres ( 26.44 mpg) driving around normally out of a MY06 STI PPP (320bhp / 330lbs)

Typically driving with 80-90 indicated, cross country. Not known to hang about. Obviously something wrong somewhere for some of you.
380-400 bhp Wagon =22-25mpg subject to right foot.
Around 600bhp Wagon =280 mls on a trip but 220 mls with cold starts, town only or during mapping.
So if you are not getting 300 mls to a tank at or below 350 bhp, excluding all town work or cold starts, it is time to start looking for the reasons.

I'd be dissapointed not to get less than 280 to a tank. 350 has been known on long runs.

I havent done a motorway run in mine yet but how can you expect a sti 350+BHP to do over 300 miles to a tank with a full decat, andy f turbo and remap??

harvey

iTrader: (48)

If it has complimentary mods, is tuned properly and driven intelligently it will do just that. If you cannot achieve 25 mpg from a 2 litre turbo there is something badly wrong.

I have much better fuel consumption after being mapped. 300 miles per tank was extremely rare, now I can usually get 300 miles and sometimes more if I cruise along motorways

Jacey Boy

As I said, I have not done a motorway run yet, but I have taken it easy and only still achieved 250 miles round town/normal work runs, there must be a very light foot somewhere watching the £1.00 litre optimax!!

guilty
350/350 uk my00

i was getting around 16MPG using it for work , 4 miles there, 4 miles back.
so,i bought a 2nd car to look after the scoob , the scoob has done 20MPG on a run though dunno what it does on a tank as i always fill it before it gets below a quarter but it never reaches 200 miles

thing is i bought a pajero turbo diesel(2nd car) and it does even less

recently did a track day with the scoob and worked out that i'd done 6MPG

bothered ? nope

scoobyDAZZA

oh,just to add, i have my map tweaked everytime i add a mod and it gets serviced very regularly, so it's definately well maintained.
Bob does the mapping

my cars been mapped by andy f, get serviced every 3000 miles, and warmed before every journey-much to the annoyance of my neighbours...
but only when it was standard i got about 250-270.... maybe because its an ra, "normal" driving is probably at higher revs than others....... but who knows.. all i know is that if the petrol prices keep on rising like they are im gonna have to buy some sort of runaround for the meanwhile....

Why warm the car before you drive it. That is a waste of fuel for a start and will affect your mpg.

Today : 331.7 mls. 52.59l Optimax.= 28.63 mpg
Sunday 30 April : 335.8 mls. 52.56l Optimax. = 29.00 mpg.
Thusday 27 April :275.3 mls. 47.68l Optimax. = 26.21 mpg.
All in Blue STi 3 Wagon and not hanging about.

Jonny Gav and I went to Liverpool in the M/Y95 WRX Wagon which was around 385 bhp at that particular time. Filled before we left and had 80-90+ indicated all the way. We were looking at a Scoob with a knackered engine and decided to buy it on the spur of the moment and tow it back. We were in a hurry as we wanted back before dark, no battery on the towed vehicle for lights. 60-80 indicated all the way back.
Filled the car up next morning at the same pump. 23.5 mpg.

If those of you who get poor fuel economy are happy with that, then that is fine but I would say there is consider scope to improve fuel economy for a large percentage of those who have posted on this thread.
Also remember that the tank is 60 litres (in most cases) so if you cannot get 55l in you are filling well before empty so cannot expect to get 300 odd miles.
Main causes of poor mpg will be poorly set up car and driving style/habits. It also helps by keeping the car light ie don't cart about all your worldly possessions in your car.

Not wanting to state the obvious, subject to mapping, your MPG is is dependent on the power you're "using", not the power you have.

Flat out, my 550bhp + (the Lateral Performance car) uses over 3 lts a minute. Howerver, it consistently gets circa 300 miles to a tank motorway cruising.

My Forrester can also do close to 300 miles to a tank motorway driving, although I need to be more aware of how I'm driving.

However, Whilst the Forrester "appears" to give similar MPG, driving the identical route to Steven Darley's, is 210 miles in the Forrester, and 190 miles in the Impreza !

So you need to allow +/- 10% for mpg, the same as you do for speedo error.

With 340ish BHP on a 2.5 with RA gearing (about 75mph @4krpm) I can get 25 mpg on a run, 17mpg around town, so if you guys can't get that on a 2.0 with decent gearing I'd check your lambda sensor!

Out of interest, how many of you that have poor mileage are running a PPP map? The best I've managed on the WR1 was about 330 miles when I drove back to the Isle of Man at a steady 80 mph (using Tesco 99 RON). Hard driving in the IOM see's about 8mpg.

On a mixture of town and A-road's, I'm lucky if I get more than 240 miles and this is if I try to economise, which isn't often

May be Prodrive have played safe and run a rich AFR on their maps to ensure people don't lean out?
