which fuel??
 
ive just bought myself a turbo and some1 has told me that i should run the car on super unleaded at all times, is this true? can u guys who have no doubt been scooby owners 4 long time advise me on this plse???

What kind of scooby have you bought? UK unmodified ones will run on supermarket unleaded; Jap import Stis are at risk of going bang without optimax plus octane booster.

Rokay 27 December 2004 10:45 PM

Uk cars should be fine on unleaded fuel. JDM models unless re-mapped should be run on the likes of Shell Optimax or BP Ultimate. add a booster additive Millers or NF booster. As a bit of reassurance a knocklink monitor is well worth having. Have a STi myself so feed only the best. Optimax + booster.

On the inside of my MY00 wagon it says "Use super Plus unleaded only"
I run her on optimax and she run fine.

mine is a uk unmodded MY00 turbo. whats the best way of checkin 4 sure? where exactly on ur car does it tell u 2 use super?

R5_GTT_Steve 27 December 2004 11:21 PM

Sorry ,its on the inside of the fuel flap.

My dealer told me when I got mine (UK MY00) that the info on the inside of the fuel cap refers to ordinary UK unleaded,which he said is "super" in Japan.At the last service I had the ECU reset and have been using Shell Optimax ever since.Has it made a difference?.......hhmmm.......I'm not sure,I think so but then I think I want to believe it has and my mind's playing tricks on me.

Read the back cover of the owners manual - "Gas station Reference"

Under "Fuel" for "Turbo Models"

Then make your own conclusion ;)

I know this has been covered a million times before and for the specialists I'll apologise for the doofishness of this question but:

a) What, in fairly simple terms, is knocklink ?
b) Is it audible ?

Its a device that basically has a microphone on the engine, it picks up noise in varying degrees, the noisier the worse the outcome, it has 5 lights on, 2 green (good) 2 amber (warning) and 1 red (knock, danger), it tells you if your car is suffering from det that you cannot hear

The best advise i can give is run it on the best fuel possible, if thats optimax then run it on it, you will notice that the car will be smoother, it will get increased MPG but you may suffer a slightly heavier right foot which eliminates this in the process ;)

my uk 02 sti has "use 98 ron only" on inside of fuel flap, dealer said it should be run on standard unleaded (95 ron) but i run mine on 80% optimax but occasionally top it up with sainburys 97 ron all seems ok with this

jowl 29 December 2004 02:19 PM

I've always run my MY97 uk turbo on Optimax though it should run on normal unleaded.

Thanks. One day I'll understand more about the mechanical side of cars than "this is where the petrol, oil, fluids etc are inserted". :D

I do know the very important stuff like:

Which is the second best car in the world ? (after a DB9 which I can't afford)

:D :D
