Hi all, i ve seen a few articles on Aussie sites/forums about deposits left in intakes/plugs and turbos from octane boosters, this can be good for the combustion process surely??? has anyone any experience of this here? one shot I saw had VERY fuzzy looking plugs.... just curious...

Cheers

 

bttt

 

Interested to know two..

Was going to start using some... intension was only to put it in with normal unleaded if I couldn't get super.. but I knew it would end up being used all the time.. Anyway... was looking into NF or Millers and then saw John Banks post with orange deposits over everything and have put the idea on hold.

Not sure if the deposits are there normally and the octan booster just coloured them or if the octan booster caused the deposits..

I shall search for the thread and link it, if I find it.

yup I remember that pic too, its the plug pic that worried me i'll try and find it... its just ive recently changed my plus to solve a high rpm hesitation and so far so good, it "only' appeared after a few months of booster use...

Cheers

 

Ive got the plug pic on my desktop but I can't upload it with turbo... any other way?

Cheers

 

you can use Turbo uploader or go to the post it is in and click <edit> and copy the image url bit out of that thread and it will reference it directly etc..

Cheers JGM, the old link I had for that was dead...

here ya go



the text with this pic just states the its due to octane boosters, no brand, but the site is Aussie

Cheers

 

Does it tell you how old they are tho'.

My plugs look fine, running 15/16psi on an MY94UK with NF and UL.
Have been fora few months now (well on my 3rd bottle of NF)

 

nope there no more info on them at all sorry m8, but i see ur point, but if this is what happens over time, imagine what the rest of the intake system will be like...

Cheers

PS: i'm a NF user too, at leat 4 bottles with UL on standard MY00 UK, so im alittle concerened...

 

My plugs had the orange coating but did not look black and bubbly like the insulators on those ones. I thought it was due to octane booster, but then others said their plugs were orange and they had only ever used Optimax.

Perhaps Optimax is NUL + NF

 

Don't too much John - there's someone doing tests who says exactly that

 

Just some background on the photos posted.
I personally know the owner of the plugs.
He used to own an V5 (? - MY00) Oz spec Sti.
PowerFC, BPM zaust, AVO FMIC etc etc....
He used to do some high speed cruising (200km/hr + )every week and used Nulon Pro Strength Octane Booster exclusively.
His Cat. converter was also contaminated by the Ob as well and had to be replaced.

 

If you plugs end up like that the recomendation is to either change the brand of fuel/fuel additive you are using or the valve guide seals need replacing.

In other words if your plugs look like that never use that fuel additive again

 

If your plugs are an orange colour, your should try a colder plug.

 

Using to much by the looks of it.
Engine can only use so much RON, Obviously thats not possible with OB from the UK.
