Increasing Gasoline Octane Overseas

I wouldn't think so.

Just a small status update. I have already been researching the toluene option and looking for paint thinner but as I said before this place is like searching for a needle in a haystack if you want something. I have already been to the turkish version of a home depot and the best I found was stripper that was 40-50 % toluene using the MSDS with a couple other chemicals which i know wont cut it. I have searched google for any paint thinners in turkey but that has proved little success as I have researched the few products that came up with little to no toluene. The chemicals here are nothing like in the states brand wise much less able to read the label. I have inquired to Torco and another supplier for the accelerator if overseas shipping would be possible so i am waiting to see on that. Is there a second or third octane booster recommended? Seems my options are getting slimmer and slimmer to retuning again or getting a legit octane boost which may not be possible.

Not really... You can give us the names of the other chemicals in the various paint thinners, I'll try to help you out.

I assume they don't use any alcohol there to raise octane.

In that case... You could run up to 10% of your favorite 100% alcohol, 1-Propanol, 2-Propanol (rubbing alcohol), ethanol, methanol (although I wouldn't want to run that much methanol)
And I'd still recommend something like MMO as a lubricant

So one company I have found is Polisan brand MX Primera thinner. This seems to be the most promising but they do produce other thinners but not with toluene.

2-butoxyethanol- 1-5%
2-methylpropanol-1 - 1-5 %
Methanol- 10-15%
Methyl acetate - 30-40%
Toluene - 30-40%

Looking into Methyl Acetate.

As of right now, I think your best bet is to take your tune off, reset the ECU, pump 90 on base, drive slowly for a tank or so to let the ECU learn, then drive with that

Xylene is ok too, you'll just need to add an additive like MMO

Or see what logs look like driving gently on the 91 octane tune.

I guess. I don't know how flexible the tunes are that a tuner puts on, but I'm willing to bet that the stock tune can fix the car to 85 octane without breaking a sweat as long as you give it a tank or two without beating on it

It depends on the 91 tune. If it's super aggressive, no. If it's a fairly conservative tune, he might be better with that than the stock map. That's why he should look at some data logs and see how it looks.

The 91 octane tune was done by jon at z1 motorsports. Mods include z1 intake manifold , Stillen Gen 3 intakes , and Fi catback exhaust. All I am looking for is a increase in one octane point to get me to 91 or 93 would be great but I have to work with what I have and being in Turkey that's not much.
