It raises the octane up to 102 (if you put in SUL to dilute it ). So it's like SUPER-Optimax. Gets rid of all the crap in the engine and puts a huge on your face!
run my 95 wrx on 97 octane (best we can get in N ireland) and NF black bottle. 100ml per tank, so i get 600 miles out of a bottle. it costs 13 odd quid but much cheaper than a rebulid IMO.
excuse my ignorance here, but isn't all this octane boost stuff for jap imports only?? thats what i was told cos i was gonna give some a try on my UK scoob.
£13 does approx 6 tank fulls- so it's cheaper for a start - and it's the only OB I have used that keeps my knocklink really quiet, plus all the other usual effects..
You can trust your engine with it but it is agood question about the cats - not sure on that as mine is decatted - e mail Dingy on here, he is the distributor for this stuff. It comes from Australia, the home of many big power scoobies, and I've certainly never heard of a problem with it.
It's what i do and I'm happy with it, and have been for about 18K miles now. If I run ordinary SUL and NF, I have to double the amount of NF to stop the knocklink having a disco.
