I have a 1993 WRX saloon with Green panel filter, Walbo, STi 2 TMIC, decat and full system, all mapped on a PFC, for about 280bhp. My daily 11 mile abode-to-work-to-abode commute - plus the occasional hoon - gets me no more than 50miles from a tenner.

Basically I get about 5 miles or less from a litre of fuel... or no more than 22 miles per gallon.

 

I've only ever used V-Power in my scoob. But would use Tesco90 if I needed...

Never used BP Ultimate, but from what I've read on here, it seems to be the Devil's ****.

 

In the scoob am lucky to get 40 miles to a tenner but the old faithful 1.8d no T van does 95 miles to a tenner. Doesnt seem to have the same smile factor tho

 

Do you have to come to Scarborough everytime you fill up?

 

I go to Guisborough now.

I use to use the Shell garage next to Proudfoot, as thats only 10-12 miles from me. The Staxton one (passed Morrisons) is too far.

But yeah, I have to travel!!

 

The joys of a scoob.

 

tell me about it!!

 

a tenner can only but you just over two gallons of fuel

I think i get about 70 miles easy A road driving which prob = 30mpg

 

i get better mpg with tesco 99 ron. i get 55 miles for a tenner

 

i use v-power or tesco99, theres no noticeable difference between the two for me, although i seem to get 2mpg more with tesco. i get 22-25mpg so thats prob 50ish miles to a tenner.

 

i have a 2000 sport special edition, it only gets about 30 miles per tenner, and that is not even hard driving!!!!!!!!

could a remap help this???

how much would a basic remap cost???

 

When driving sensibly I get 40-50 mpg think its the going rate tbh mines high milage

I have a standard turbo 2000 on a T reg 103k milage run on 95ron no problems.

Its been proven that tesco 99 ron is the best out of al uk pump fuel for power and ecomomy in a test done by thorney motorsport

heres a link for you to the page and test its awesome the results!

BP ultimate is like nats ****!

Coolant temp sensor!!!

 

LOL I put some of Texaco's finest in once... Never again.
I was running low and it was the only garage for miles, the car ran like a dog. I thought the head gasket had gone or a plug had died... NOPE it was there crappy fuel!

Tesco 99 or V power for me

 

what is this?

and how do i fix it or how much would it cost to replace/repair?????

 

I have no trouble with Texaco 97. I use it (and sometimes Esoo 97) if I think I can't make the Shell garage lol.

You prob just happened upon - unfortunately - a stale batch...

Subaru Impreza Turbo ECU Water Coolant Sensor

 

do you guys agree that this is likely to be the problem???

what would you guys estimate my car (2000 sport) should do per tenner?

 

Is it running rough? Does it want to stall, or the revs dip and rise, as it's warming up? These are typical symptoms when they are on the blink.

It certainly could be the problem i.e. if it's knackered and its output voltages are out of range, then it's probably telling the ECU to overfuel an up-to-temp engine - hence the bad fuel economy.

For the sake of only £30 (equal to a a 60% fill up!), then I'd defo replace it and see how it goes... it'll pay for itself in only a few miles if you gat back to normal consumption again.

With a non-turbo, I'd expect about 25-30mpg on the combined cycle (it won't be much more than that, as the AWD system saps a lot of the engine power).

 

i am a bit worried that the part will not fit as my car is a 2000 sport and the link says it will fit All Impreza Turbo's 1992 to 1998

will it fit or do i need to find a one for my car?

 

See post # 11 in that thread link above...

...Of course, it could be your O2 Lambda sensor...

 

do any of you guys use the octane booster?? iv heard people mention to keep some in glove box if u really are stuck middle of nowhere and last resort is lower octane stuff, never tried it to be honest just wanted see if guys have tried it.
J

 

I wouldn't bother.

Just stick in enough 95 to be able to get you to a Shell or Tesco, drive there off-boost, and then fill up with the proper stuff when you get there. # simples #

 

if i am dion local journeys which is alot of the time i use normal unleaded but if im gion on more of a trip i use v power or optimax

 

is there any way to test if this is working?

 

O2 Lambda sensor???

 

Get a duel map
one 95 and one 99, then theres no need to worry.

45 miles for a tenner drivin normal

10 miles for a tenner on track

 

i get around 100 miles for £20 using tesco 99 but if i give it some goes down to around 70

 

tesco 99

 

10= 35 miles to work and back then around town a little
