what fuel do you put in your impreza unleaded or lrp (4star) cant find super unleded around.

optimax, 99.9% of Shell sell it. cheaper than SUL.
get the pamphlet next time your in shell.

Bloody hell dont put this in your car, you will damage your o2 sensor and CAT in no time...!!!

The stuff doesnt even have a british standard so someone told me..???

Dan:D

Is Optimax really cheaper than SUL now? What about all the stories of it killing engines, or are they just bs?

I use Optimax w/ no problems, ~78.9ppl here in the northwest

I use Optimax and SUL (when I can't make it to a Shell garage !) ... these are about the same in East Herts, SUL about 2ppl cheaper at the mo ....

Cheers
Phil :D

dump...DONT use LRP end of story !

yaeh and if its an import use octane booster!

I used unleaded dont panic but just looking for a opinion. Whats this octane stuff.

Octane booster is mainly used for jap imported cars, they are run over there on 100 ron, our nearest is optimax at 97 - 98 ron from shell, I use millers octane booster, 1 bottle per tank which gives that extra 2 ron.

simb

I use Shell V-Power 100 octane available at *ALL* Shell stations in Germany! Before that ran on Optimax! Both in UK spec PPP RB5 and German spec STi-8 before that 98MY UK spec on SUL - Never had any problems using SUL/Optimax/V-Power!!! RB5 PPP hated the occaisional 95octane UL when I couldn't find SUL in UK! 98MY gave better MPG with SUL than 95octane!

Dump, dont you have a 94 WRX?
then you really ought to be using octane booster IMHO..
not just standard unleaded.

Ft (with the *bright* button)...;)

heard theres a guy in dumfries has a scoob running on mineral water with no probs

if you have an import you can just run it on Optimax cant you? have been told that before before, hope its true, how much does octance booster help though? where can you get it? and how much does it cost??

Just a quick question. Is it really necassary to use octane booster in an Import. I am in the process of getting a STI wagon from a Jap importer and they have said that they will take care of everything including SUV. I was under the impression from their literature and talking to other Impreza drivers that this will make the car pretty much the same as a UK car. Obviously I want it to be more powerful.... (around 265bhp which is what they have told me) but is the octane booster to up power even more or must it be used every day if the thing is to run properly ?

Too late to cancel as cash has been transfered, but an idea of if I need to be bulk buying octane stuff would be appreciated.

Finally whats the best stuff to use then, and where does it come from ?

Dan.

I've a 1999 wrx import & been told to run it on Optimax only or super + octane booster is this true????
...cos dont want to melt another engine :( :(
