As this is the OB thread (primarily) I have replied in the 'Optimax' thread.

for those of you that are intrigued by the octane boost offered through the use of toluene further reading is available here

Really intrigued by this thread, and the various inaccuracies within. Just have a quick question for Mycroft.

What's this institute you mention earlier in the thread?

Mycroft

A minor discussion has started on Scooby-net on this subject... so far there is nothing on there is not already in here... but it may generate something new, I will transfer anything 'worthy' over here.

An engine running optimax and booster with no deposits???
Mycroft, you said ........;-)!!!
So perhaps this is not just specific to optimax afterall??
Manganese or something wasn`t it mycroft?
This is really turning into a nightmare......i`m buying a steam engine!!

Jason I think you may not have understood John Banks posts.

John Banks is running Optimax and an OB and he has it.... in fact his motor seems to be coated in fine layer of it...
---------------
I said that the deposit (and I quote) :-

#As he talked me through each car after about 40 minutes or so (yep, a telephone conversation that could have bored the pants off a frigid nun locked in a fridge in the middle of a frozen lake in the Arctic circle) a pattern emerged, all these cars had run Optimax and Octane boosters which is exactly as I suspected the moment I saw that chrystal structure.

Now I must emphasise that NO DAMAGE had occurred, a few very cautious owners had paid for a couple of very expensive re-builds.

This is why this thread has been revived..because almost all the contributors and many of the readers of this thread I believe are just that cautious and enquiring.

Moral..It may look like rust, it may seem like you are heading for a big bill, but if you use Optimax with a high Manganese Octane Booster then don't have a brown trouser moment, check everything first, perhaps a little less OB?#
--------------------------------------
He also says he may have seen a similar thing but he ran both SUL with OBs'.

Steve W asked:-

#are you saying the manganese is from the OB, or, from the
Optimax ? ?

and,

is this deposition only occuring because of the combined use of
both ?#

To which I answered:-

#From 'which' it is impossible to tell, it appears to happen when both are used in combination, Opt and OB.#

It is only a nightmare should you only partially read the thread... this is a thread that needs the reader to think...

Some further reading of experiences regarding the OPTIMAX side of this thread... on page 2, I clarify further my thinking... should you require it.

http://www.scoobynet.co.uk/bbs/thread.asp?ThreadID=207812&Page=1

Should you not wish to trawl through further pages... I don't blame you!!!... my post below my 'contribution'...

###
Optimax cleans the cylinders and head... now once the deposits are gone the reason for your retardation goes as well so you can then return to SUL and it won't retard so quickly... so the real value of optimax is as a cleaner... run it every 5th-6th tank full and the car will be faster overall... you may need 2 or 3 tank fulls to clean it out in the first place but that is it.. in a nut shell, if you run rich and have dark Sparks normally then you should really attend to the fuelling but if you dont then Optimax is good at stopping a big build up of carbon...

EvoRob

Mycroft! What do you reckon to this fuel combination and do you think that it could possibly cause internal detonation?

1 Portion of donner meat and chips, onions, tomatoes, topped with lashings of hot chilli sauce and Garlic Mayonaise and using a can of Tango as a Booster?

Ive not tried it in my Evo yet but it deffo makes me do the quarter mile when im on foot a lot quicker as the chilli sauce gives you a lot of back pressure!

P.S Could you do a lab test for me on that and the possible increases in internal activity that it would create!

Keep up the good work! V-Bird

senna

she-eet EvoBob, that aint on-topic.. someone will have to remove your post.

Heaven help anyone who tries to inject a little friggin' humour.

Steve W

Mr. Myc'... or others ? ?

Burtons (Gants Hill... Ford-ie place) sell Aldons Booster.

It is a 1Litre plazzie bottle and says "contains Xylene Isomers,
TOXIC " etc etc.

It stinks of Paint-ie smells (NOT Toluene, I KNOW what that smells
like - used it in old job)

Q: Is THIS liable to be 'more' Xylene-ie/Toluene-ie in nature than
the likes of Millers etc.

ie. better at actually increasing OCTANE rather than allowing
the Timing to be advanced ? ? ?

(I'm having trouble finding a local Toluene supply and trying to
find some CR*P-in-a-Bottle that'll nearly do the job ! ! )

FatS.

Avoiding Evorobs' diversion as best I can, this thread has to be 'revived' again... due to the introduction of BP 'Ultimate'.

Steve W... you need at least 7% by volume to make any tangible difference. little bottles = little difference.

There has been some discussion on other forums about this 'new' fuel, sadly almost all has been 'wrong headed' or has entirley missed the point.

In an effort to do what all the refinery companies shy away from I will try to explain how things are not always what they seem.

As usual, you need some history for this to make some sense.

In this Country we adopted a system of 'Star'[*] ratings for fuels after it was found that one 'Super' grade of fuel was not as 'super' as it maker would have had you believe, so the introduction of Star ratings came about 2 3 4 and even 5* fuels could be found on the forecourts of the UK.

After a short while even this was 'abused' and further more accurate measures were needed, at this time we faced a choice, we could go for either the 'expensive to check' MON or because of the ESSO companies '100oct 5*' fuel logos on their pumps the alternative bigger numbered RON system, at the time RON was a better guide for the more uniform fuel found in the UK [very small temperature variance through the year] So we then adopted the RON system and the numbers we love to 'bandie' about like '95' '97' etc were 'enshrined' here.

I could if you wish explain the difference between RON and MON in some detail but ditchwater is less dull so I won't.

So all was fine, the fuel until very recently fitted very nicely within the accepted formula from one system to another... you see until now 100 RON always was 91.5 MON and vice versa...

This was due to the base and top out chemicals used to form the basis of the 'formula'

Then they started making some rather neat coc-ktails that really started to blow holes in this, our chosen rating system, you see the real figure that matters is not RON... the really important rating is MON... you could say that our system of rating has been made somewhat redundant...

So although we may rate a fuel here as 97oct [RON] which would have been 89 MON in reality it will still only attain 97 RON but might show 91.5 MON when tested to that 'standard' now by the old conversion factor to get 91.5 MON you needed 100 oct [RON] fuel.

I hope that clears this little matter up.

Questions?

Howsie

Mycroft, I don't suppose the oil compaines list MON ratings anywhere because of this then? Are they listed anywhere on an independent reasearch site or have you done you own?

Cheers,
Howsie

Mycroft

Now you come to mention it, but I do have that info and I will tomorrow endeavour to retrieve it from the system and on my return from my duties post them on here.
