Hi,

What sort of MPG will I get from a 02 plate sti with 340bhp remapped, fuel pump upgrade and decate pipe? Hard driving and careful driving.

 

my classic is running 351 and caareful driving sees 23-25mpg giving it some toe sees anywhere between 7 and 12 mpg depending how hard you push its a brand new 2.0l p1 engine forged build hope that helps a little enjoy the fun times

 

if mpgs are a concern why buy or think ov buying, its not gonna be good

 

 

my 4.0l lexus does better than that.

 

i get 14/15mpg combined 315 bhp(est) lucky to see 200/210 mile on a tank anyway..put it this way if i get 70 miles by the first quarter line on the guage after fill up am happy then half tank shows 110 then its just down hill from there on looking for a shell sign...they aint much diffrence in driving soft or hard fuel still gose so use it wisely i.e just have fun

 

Same as, do you know if the tank is bigger at the top? as mine seems to take a while to get to full then to 1/2 seem slower than 1/2 to 1/4?
after it goes passed 1/2 it seems to drink it not even on boost nice and steady, I only put £20 in this week and this is the least i've put in since owning the car, My partner puts £20 a month in her 206 and drives more than me or so it seems, may be a 206 on the cards? I dont thinks so

I would like to know how much other have blown on fuel in a week or so i normaly do £50, which is around £8 a day on average and if i got a taxi 1 ride would be more than the scoob, I think i will keep the scoob

 

70 quid a week easily, in the summer alot more driving length and breadth of country and evening week day use as Ive a van for work thank god..i think nothing of just geting in the car on a sunday and doing 300+ mile round trips all over the place i just love driving it 14000 miles+ a year and dont use it for work

think so cos it has a cut out at he bottom of tank to fit over the chassi for the prop shaft think its why it has a float fo the guage at each side of the tank to compesate this though

 

My 350bhp STI does 14mpg round town with a bit of hard driving in between, motorway off boost i have seen 27! track day......well into single figures!

 

Ive just bought an import version 2 and im pleased with the MPG so far, if i get 200 miles to a tank i will be dead chuffed, i usually drive a 4ltr landrover hybrid which averages 9 around town and around 14 on a run so the scooby is my cheap run around lol

 

I'm not sure how to work out MPG, but I get 250 miles on £55 petrol but i get 250 miles on £34 of LPG

 

£55 is about 50 litres. 250 miles / 50 litres = 5miles/litre. 4.5litres in a gallon. therefore 5 x 4.5 is about 23 mpg

£34 is about 63 litres of LPG. 250 miles / 63 litres = 4miles/litre therefore 4 x 4.5 is about 18mpg

HUH????? my maths must be crap. your getting more mpg out of SUL than LPG.

 

your mileage for LPG must be wrong. it has to be more that 250 miles to a tank of LPG

 

Must get me a SUL conversion then lol

 

1. Let car get low on fuel...
2. Brim up...
3. Zero odometer...
4. Do the miles, let fuel get low again (anywhere)...
5. Brim up again...
6. Check how many litres go in (this is how much fuel you've used for the miles showing on your odo...
7. Divide these litres by 4.546 to get to gallons...
8. Then divide the recorded milage by the gallons...
9. Hey presto, a pretty accurate MPG calculation.

Continue from point 3 to start the process over again...

 

10, say "i cant believe it" over and over again
11,after doing this a few time and realising rubbish mpg..accept the fact n hav fun

 

LOL! Too ruddy true andy!

 

It's because LPG you get double fuel for you money, LPG you get less mpg but cost half the price.

 

i get about 28 when sensible on the motorway. about 8-12 when giving it some.

This is a classic STI with filter n 3" decat. pre fuel pump n map.

 

totally depends on your tank size. MPG is actually worse on LPG than petrol, but it costs far less so you have to work out the 'equivalent' MPG which varies depending on cost of LPG and SUL at the time. Hard driving I get about 18MPG on petrol or equivalent on LPG for the same driving is about 28MPG at todays costs. Or to put it another way it costs me £0.27/mile to rag it on petrol or £0.17/mile to rag it on LPG

Here in france the equivalent is higher at 34mpg due to the prices here. Back on UK prices this goes up to 29/46mpg for SUL/LPG respectively on a gentle motorway cruise (55mpg equiv on french prices).

 

Spot on


Our Imprezas may have crappy MPG but its a great car to drive.

When I start to worry about MPG I will go and buy a Fiesta lol

 

And if you've not got a heavy right foot and do 20 mile journeys to work... I get over 300 miles to each tank of £45 - almost exactly 30mpg everytime.
