Hi Guys,i live in rep of ireland and 97-98 ron petrol seems to be getting near impossible to get so im just wondering could anyone recomend me using 95 ron with octane booster and if so any specific type of booster,i have a tin of pro boost not to sure if its any good.

Cheers guys(its a 99 sti version 6 by the way)

 

ProBoost is Ok, Put the whole tin in to a tankful especially on 95Ron fuel & don't wrag the **** off your Scoob & all should be fine,
Is it A JDM ?? Import, & if so still on the Standard Jap 100 Ron Map ?? All the more reason to not thrash it on Uk Fuel.

You'd need a fair bit of OB to get the octane up to 100RON (a whole bottle of NF = 6RON? @ £13 a bottle). May be better to have the car mapped to whatever fuel you can get hold of and however much OB you are prepared to use all the time.
